II. Conference progress. Part I (lesson 8)

Conference Chairman opens the session:

- Dear Sirs! Allow me to open the conference "Insect pests and measures to combat them." Well-known entomologists are present here, who will help us learn more about the biological characteristics of insect pests, about the characteristics of plants damaged by them, which will help in the future to fight hard against harmful six-legged.

When we talk about insect pests, we are not talking about the damage that insects cause to plants, but rather the damage they do to the economy. We know that most insects eat plant foods. But are they all pests? No, not all. Pests are those that periodically give outbreaks of reproduction and during these periods they literally destroy vegetation. Such insects include, for example, locusts. The calculations of the English naturalist Carruthers, who in 1889 observed the flights of huge swarms of locusts across the Red Sea (from North Africa to Arabia), make it possible to judge the results of the mass reproduction of insects. The space occupied by one of these flocks was 2304 square meters. miles (5967.36 sq. km.), and it was not the largest of the clouds seen by Carruthers. The weight of this cloud was about 42 million tons, and the number of individuals was at least 24,400 billion (according to A. Brem, "The Life of Animals").

An example of the possibility of mass reproduction (under favorable conditions) and the appearance in a short period of time on large areas can be the winter scoop, the female of which lays up to 2000 eggs, and in the south the butterfly gives 2-3 generations in summer; many species of aphids have 12-18 generations during the summer, 40-50 individuals from each female, and the possible offspring of one female is calculated by astronomical figures by the end of summer. The offspring of only one female could cover our entire planet with a layer 3 m thick! Fortunately, this does not happen in life, aphids are destroyed by adverse weather conditions, pathogens and various predators.

In our area, pests are, for example, insects such as aphids, woodcutters and many others. Our esteemed experts will introduce us today to some of them.

Pests of field crops

Many insects are crop pests. Feeding on various parts of plants, they can drastically reduce the expected yield. Knowledge of the features of the external structure, development and lifestyle is a necessary condition for combating them.

Asian, or migratory, locust.

Locusts are representatives of the order Orthoptera. They differ from grasshoppers similar to them in short antennae, never exceeding a third of the body in length. Single forms are called fillies; those that form mass aggregations are locusts.

In autumn, the female locust, with the help of the ovipositor, lays eggs deep in the soil, at the same time releasing a foamy substance, which, when hardened, glues the eggs into one continuous capsule. The eggs laid in the pod remain to winter. In the spring, young locusts, similar to adults, but wingless, hatch from eggs that have overwintered in capsules. Eating intensely, they quickly molt 4-5 times and after the last molt become sexually mature and capable of flight (frame 6). The most interesting biological feature of the locust, discovered by the English entomologist B.P. Uvarov, is the presence of two development programs. If the population density of juveniles hatched from eggs is low, then the protective coloration of insects is more pronounced, and they have no interest in traveling. On the contrary, if the number of individuals per square meter of soil is large, then their development is associated with the neglect of camouflage and a powerful desire for organized migration.

Accumulations of flightless locusts are called swarms. After the last molt of insects, when they "stand on the wing", their clusters are called a flock. A swarm of locusts is dangerous, devouring everything living on its way, but a swarm of locusts is especially terrible. Young locusts are highly dependent on succulent food, so their breeding sites are usually close to wet lowlands. That is why the mass appearance of bands and flocks is preceded by rainy years. With age, the locust becomes more and more omnivorous, while adults devour everything vegetable, up to the young bark of trees, because they have powerful gnawing mouthparts.

Neither the natural enemies of the locust, nor the measures taken against it in the fields could protect the country from new locust raids. The fact is that the main places of locust hatching are not fields and not steppes, but marshy “floods” overgrown with reeds and reeds in the lower reaches of the southern rivers - vast places where in former times it was almost impossible to reach. These floodplains, where the locusts had fresh food all summer, turned out to be the natural reservoir from where, after fledging, they made their raids on neighboring, and sometimes very remote agricultural areas.

In the reduction of locust breeding centers, a large role is assigned to the chemical method. If locusts appear in alarming numbers, strong insecticides (chemicals used against insects) are resolutely applied, making sure that after their use there is no grazing here for a month or two.

Bread beetle.

A one and a half centimeter beetle with red elytra in June sits openly on the ears of ripening rye, wheat, barley, gnawing grains. Having devastated about a dozen ears of corn during their free life on cereal, the beetles mate, after which the female lays up to 50 eggs deep in the soil. The arcuate larva, yellowish with a brown head, spends about 22 months in the soil, feeding on the roots of various plants, including cereals. If there are more than 20 bushes per square meter of eared cereals, the crop can be considered almost completely destroyed by pests.

Bedbug turtle.

The harmful turtle is one of the most dangerous pests of cultivated cereals, especially wheat and rye. Adult insects hibernate under fallen leaves. In the spring, they "stand on the wing" and fly to the plantings of cereals. Here they feed for some time, sucking the juices of plants; then, after fertilization, the females lay up to 200 eggs on the lower surface. The emerging larvae first feed here, and then gradually rise up to the young spike. When the grain is poured and hardens, the bugs inject enzymes (digestive juices) into it, converting the gluten into a liquid state, and suck out the contents. Damaged grain becomes puny and wrinkled. The flour obtained from such grains is unsuitable for baking bread, as the damaged grain loses its gluten.

In autumn, having acquired the ability to fly after the last fifth molt, the turtles move to the forests, as we already know, for wintering under fallen leaves. There are years when turtles appear in huge numbers, arranging pogrom and devastation in the grain fields. The harvest from plants weakened by bugs is sometimes lost almost completely. This is usually preceded by mild winters that preserve the entire mass of hibernating bugs.

That's all I would like to talk about in my report. But I have a few questions for you.

- Representatives of what orders of insects are pests of field crops?

- Are there representatives of the order Lepidoptera or Butterflies among the pests of field crops?

- Look at the appearance of the winter scoop. Determine by appearance which group of diurnal or nocturnal butterflies it belongs to, provide evidence.

- Find a continuous broken line that would go around all the cells in such a way, without intersecting anywhere and without going anywhere twice, so that, following the line, you can read about the meaning of click beetles.

Pest control

Most species of ladybugs are voracious predators that feed on harmful insects. About 100 species of ladybugs live in Russia, all of them are small in size (the length of the adult body is from 1 to 18 mm), differ in the shape and degree of flattening of the body.

The most common species of the family is also very useful - the seven-spot ladybug. Beetles and larvae of the seven-spot ladybird feed on aphids, scale insects, and plant mites. Insects are quite voracious: in one day, a ladybug larva eats up to 70, and an adult beetle - up to 200 aphids. In addition to the seven-spot ladybird, more than 20 species of ladybirds can live in the garden. Cows, laying eggs, attach them in places of accumulation of sucking insects, and the emerging larvae immediately pounce on the prey. No insecticide, even a biological one, can cope with the suppression of aphids as successfully as a ladybug.

The method of intra-areal dispersal consists in the relocation of entomophages within their range from old breeding centers of the pest to new ones, where the entomophage has not yet had time to accumulate. One of the pests of the tea bush is the tea pulvinaria (Holiptera order, the family of grasshoppers and false scale insects). In the fight against it, the predatory beetle of hyperaspis is settled, which destroys the eggs and larvae of the pest.

In the microbiological method of control, pathogens of pests are used - bacteria, viruses and fungi. Even in the USSR, the bacterial preparation entobacterin was created (gray powder, which is used in the form of a suspension for spraying fruit in the fight against gnawing pests). More than 50 species of insects are known to be effective against; it is used, for example, in the fight against apple moth, hawthorn, cabbage moth, American white butterfly. However, it must be remembered that biological preparations in high concentrations can be harmful, and some substances, even in a minimal amount, can be deadly. Therefore, you need to use them, following exactly the manufacturer's instructions. Plant protection products contain, in particular, the following substances of natural origin:

bikol- acaricide. Prepared on the basis of the bacterial strain Bacillus thuringiesis var. thuringiesis. Used in the destruction of spider mites. Has an intestinal effect on pests. Bitoxibacillin- acaricide. Prepared on the basis of the bacterial strain Bacillus thuringiesis var. tenebrionis. Used in the destruction of spider mites. Has an intestinal effect on pests. It differs from the previous preparation in some additives (various special wetting agents and adhesives are added to them).

Boverin is an insecticide based on the fungus Beauveria bassiana. Used against thrips. Plants are sprayed with a 1% solution of the drug. Verticillin- an insecticide prepared on the basis of spores of the fungus Verticillium lecanii. This drug is used in the fight against whiteflies. Its action lies in the fact that the conidia or blastospores of the fungus penetrate the integument of the insect and penetrate into its body, growing and affecting its organs. Mushrooms Verticillium lecanii reproduce especially well at high air humidity, therefore, before applying the drug, the soil in the pot should be thoroughly sprayed. Before using the drug for 12-24 hours, it is soaked in water to accelerate the germination of spores. Gaupsin- a bioinsecticide and fungicide, a two-strain broad-spectrum preparation intended for treating gardens and kitchen gardens, as well as for protecting indoor plants from fungal diseases and various pests (curly, black spot, powdery mildew, bacteriosis, late blight, septoria, black rot, aphids, spider tick, caterpillars, thrips, etc.). The manufacturer claims that the effectiveness of gaupsin in the fight against fungal diseases is 90-92%, with pests 92-94%. The biological product is not toxic to humans, animals, fish, bees, does not accumulate in plants, soil. In addition, gaupsin is compatible with many pesticides (except for Bordeaux mixture and other copper-containing chemicals - after their use, the first treatment with gaupsin is only after 21 days). The drug is diluted with water at room temperature at the rate of 200-250 g of gaupsin per 10-12 liters of water. Use only freshly prepared solution. Freezing of the drug is not allowed.

Many harmful insects are destroyed by insectivorous birds (tits, flycatchers, starlings and rooks), as well as frogs, toads, lizards, moles, shrews, hedgehogs and bats. Of the birds of prey, the most useful species is one of the small falcons - the kestrel, which eats rodents and insects. The common buzzard, or buzzard, mainly feeds on rodents. Most species of owls are useful.

Insects in the house are a phenomenon that is unpleasant in all respects, which causes a lot of inconvenience to its inhabitants. Insect control is a necessary procedure to help get rid of pests and their detrimental effects on human health, as well as on furniture, clothing, and food. What methods and means for controlling insects are best used, you will learn from this article.

What types of insects are most often found in the house?

• flies;
• mosquitoes;
• ants;
• cockroaches;
• fleas;
• ticks;
• bedbugs;
• mol.

What harm can insects cause and why fight them?

It’s not worth just ignoring various arthropods, and it’s unlikely that it will work, as pests will constantly remind you of their presence. Peaceful coexistence with them is impossible in principle for the following reasons:

1. Insect bites are very painful and can cause severe allergic reactions.
2. Many of their species are carriers of various infections that are dangerous to human health.
3. Insects can spoil food, clothes, furniture.
4. The presence of pests in the house is also unfavorable from the point of view of aesthetics - few of us will find a cozy apartment where cockroaches run in the kitchen, and flies are literally teeming in the living room.

On a note! It is almost impossible to protect the house from the appearance of unwanted “guests” at 100%. Insects can not only fly into rooms through open windows, but also enter housing through sewers, ventilation, and cracks under the door. It is not uncommon for them to enter the house with food, bring things or cling to shoes. In an apartment building, insects may well move to you from neighbors. In this case, insect control must be organized immediately and all residents of the entrance should be involved in this. Only in this way disinsection - an event for removing insects, can be effective.

What are the challenges of pest control?

The main problem in breeding insects is that they are very tenacious, persistent and are distinguished by their ability to adapt to any environment, temperature and humidity changes, and even to the means used against them.

Here are just a few facts that will convince you that pests that have entered your home show amazing vitality:

1. Cockroaches - they can go without food for about a month, they are omnivorous - they can even eat cosmetics, in addition, they can live for several weeks without a head.
2. Bedbugs - able to survive in almost any conditions, even in the absence of food and air, while the female bug lays 5 eggs per day.
3. Flies are even more prolific and lay 100 eggs per hour.
4. Fleas - able to attach eggs to any surface.
5. Ants - arrange their nests in hard-to-reach places, and the population of the anthill is more than 1000 individual individuals.
6. Almost all insects are resistant to radiation.

On a note! We hope that the above information will finally convince you that the fight against insects in the house is a difficult but necessary process, and the sooner you do it, the better. Difficulties arise due to the fact that many insects tend to mutate and can become immune to certain types of substances. Therefore, it is extremely important not only to choose the right means that repel and destroy pests, but also to use them in the required concentration.

What are the pest control methods?

There are several ways to control insects and pests, which are characterized by different directions of action and can be applied in practice:

On a note! Individual methods by themselves are rarely used. Most often, you have to combine several methods at once, and sometimes even insect control means, for example, physical with mechanical or chemical.

What pest control products can be used in an apartment or house?

Disinsection - the fight against insects, as a rule, is carried out in two directions:

• preventive measures - the creation of unfavorable conditions for the life and reproduction of insects in the premises;
• extermination measures - the destruction of pests that have appeared in the chosen way.

Depending on which types of pests you want to get rid of or even prevent their appearance, the following groups of insect control agents are recommended for use.

Prophylactic

Aimed primarily at the destruction of flying insects. Include:

• Repellents.
• Spirals.
• Fumigators.
• Mosquito nets.

Chemicals - insecticides

Forms of application:

• suspensions;
• powders;
• aerosols;
• crayons;
• dusty.

Folk remedies

The main thing is the use of natural ingredients. Advantage - they can become an alternative to chemical agents if it is necessary to remove insects in a house where there are allergy sufferers or small children. The disadvantage is that, as a rule, they are ineffective, since they are aimed mainly at scaring away, and not at the extermination of insects.

Recipes for folk remedies for insect control

If you decide to start your fight against insects with the most gentle and safe means from the “folk” category, use the following recipes, tested by home craftsmen in practice.

Method 1

If there are fleas, ticks or bed bugs in your carpets, try to deal with them using the simplest method:

1. Mix equal proportions of salt and soda.
2. Sprinkle the dry mix over the carpets.
3. Leave overnight.
4. Vacuum thoroughly in the morning.

Method 2

You can remove bed bugs from upholstered furniture using the following recipe:

1. Take 1 liter of clean cool water.
2. Squeeze the juice of 1 lemon into it.
3. Pour into a spray bottle.
4. Treat beds, sofas, pillows and all textiles with the resulting solution.

On a note! To make the solution more saturated, you can boil finely chopped lemon in boiling water for 5 minutes, then strain and add to water. Next - apply according to the scheme.

Method 3

Some types of insects cannot stand certain smells. To disinfect surfaces and repel pests, proceed as follows:

1. Pour 5-6 liters of cool water into a bucket.
2. Add 8-10 drops of aromatic oil - lavender, eucalyptus or rosemary.
3. Wash the floors in the house with a solution.
4. Change the water.
5. Add your chosen fragrance oil to it again.
6. Wipe down all walls and surfaces.

Method 4

In the fight against small insects - fleas, ticks and bedbugs, the following solution will help:

1. Take dry, strong-smelling herbs like mint, eucalyptus, rosemary, or lavender.
2. Prepare a decoction - boil in a steam bath or pour boiling water in a thermos and let it brew for about 30 minutes.
3. Pour the decoction into a spray bottle.
4. Spray sofas, armchairs and other upholstered furniture with the solution.

Most popular pest control chemicals

Folk methods no longer work, because you missed the moment and the insects have long settled on your territory? There is a way out - on the modern market there are a lot of various drugs that will surely help you neutralize flying or crawling pests. The most famous of them are:

• Raid.
• Raptor (Raptor).
• Dichlorvos.
• Combat.
• Gel “Clean House”.

On a note! If you find it difficult to choose the right means or, having tried repeatedly, they no longer give the desired result, invite representatives of the sanitary and epidemiological station or use the services of a special insect control service that will carry out high-quality disinfestation of residential premises using the most effective means to date. However, keep in mind that the involvement of specialists will require certain financial costs from you.

We hope that the tips in this article will be useful to you, and you will be able to choose and apply the most effective insect control agent correctly. Good luck in this difficult but necessary event!

The season is coming! The season is not only gardening, but also mosquito, fly and gadfly ...))) Yes, soon in all gardens of the country we will endure the bites of mosquitoes, gadflies and annoying flies!

It is known that it is possible to fight all pests with chemistry, but

• firstly, it is harmful to our health,
• secondly, it is harmful to the environment,
• thirdly, in such a struggle we exterminate beneficial insects

So what to do? And there is a way out! Nature has thought of everything for us a long time ago! The main thing is to learn to read the Book of Nature!

We consider many plants to be weeds and as a result, the more well-groomed the site, the more pests. And Nature has long taken care of this and solved the problem. Green pharmacy, not only heals, but also has repellent properties.

Plants containing certain specific substances are called repellents.. Phytoncides, released into the environment, have a depressing or irritating effect on certain animals.

As a result, many pests "without a fight" leave the occupied territory and go in search of a better life.

The best way to expel pests is to plant the most suitable repellents next to the cultivated plants.

1:2647

The role of plants - repellents!

1:64

2:568 2:573

First of all, these plants act as protectors! They protect our gardens and gardens, as soon as they are planted in certain areas of our gardens. Who are they protecting from?

2:907

From the whitefly

2:946

3:1452 3:1457

Effective infusion of garlic. Chopped garlic cloves (150-170 g) pour 1 liter of water and insist in a tightly sealed container for five days.

For spraying, 6 g of concentrate diluted in 1 liter of water is enough. Keep in mind that folk remedies can help if there are not too many pests.

3:2001

It is more effective to plant nearby repellent plants: nasturtium, peppermint, thyme, bitter wormwood.

3:201

From white cabbage

3:253

4:757 4:762

10 g of white mustard powder is infused for two days in 1 liter of water, filtered and before spraying, bring 200 ml of the solution to a volume of 1 liter

Chamomile infusion and hellebore infusion give good results. For 10 liters of water, take either 1 kg of raw, or 500 g of semi-dry, or 100-250 g of dry hellebore.

This solution is infused for about two days or boiled for 30 minutes. A decoction or infusion is filtered and used for spraying.

It is more effective to plant nearby repellent plants: celery, tomatoes, peppermint, sage, bitter and medicinal wormwood.

4:1720

From the cabbage caterpillar

5:557 5:562

repellent plants: onion, sage, tansy, thyme, medicinal wormwood, nasturtium.

5:707

From an earthen flea

5:756

6:1262 6:1267

when fleas appear, the plants are pollinated using sifted wood ash, tobacco dust (in equal proportions) by dew.

6:1495

And one more recipe for an old, undeservedly forgotten means of dealing with a wide variety of insects:

6:1689

In an enameled or metal vessel with a capacity of at least 5 liters, boil 1-2 liters of water, dissolve 200 grams of laundry or green soap in it and bring to a boil, after which 200 grams of kerosene are added.

The mixture is forced to boil two or three times, removing from heat when it rises in foam above the level of the dish. The resulting emulsion concentrate is diluted with warm (30-40°) water to 10 liters.

6:742

But it is more effective: plant repellent plants nearby: catnip, peppermint, bitter and medicinal wormwood, tobacco, tansy, head and leaf lettuce.

6:1025

From the five-point hawk

6:1088

7:1594

7:4

good results are given by infusion of calendula and peppermint. For 10 liters of water, take either 1 kg of raw or 500 g of a semi-dry mixture of plants.

7:237

But it is more effective to plant nearby repellent plants: dill, borage, basil.

7:387

From the Colorado potato beetle

7:440

8:946 8:951

for the successful use of folk remedies and methods of dealing with the Colorado potato beetle, it is necessary to fulfill a number of simple requirements when using them.

1) It is recommended to process plantings in warm (at a temperature of 18-25 ° C), calm weather, in the morning after the dew has dried or in the evening before it appears. It is better to spray herbal preparations in the evening hours, since in the sun they lose their insecticidal properties faster.

8:1747

2) Working solutions must be prepared 1-3 hours before spraying. For better adhesion, green (potassium), laundry soap, liquid soap or washing powder is added to them. Usually 20-40 g per 10 liters of solution. Having previously cut and diluted the soap in a jar of water, pour it into the working solution.

8:554

3) Treatment with infusions and decoctions is repeated after 5-10 days as needed. The last spraying is carried out 20 days before harvest.

8:816

Folk ways to deal with the Colorado potato beetle:

8:913

9:1421 9:1426

A week or two before planting potatoes in the garden, dig several holes up to 10 cm deep. The earth around them is sprinkled with hot coal ash and slag taken from the furnace of a boiler or stove. Beetles crawl into these holes and die. In the same way, peat or wood ash has a detrimental effect on the pest.

9:1986

In the spring, before the emergence of potato shoots, 3-4 pieces of tubers are placed in half-liter jars. Then the banks at 10-11 o'clock are placed on the site in the recesses previously dug in the ground. Beetles caught in jars are destroyed.

9:410

It is recommended to soak tubers in the spring for 1 day in a solution of urea. Lay out on the site in cloudy weather or at night. The beetle dies by attacking poisoned baits. This method is repeated in the fall after harvest. (CHEMISTRY)

9:861

An infusion of wormwood with ash is also used: a glass of wood ash is added to 150-200 g of crushed fresh wormwood, everything is poured with hot water, infused for 2-3 hours, stirred, filtered and potato bushes are sprayed with the resulting liquid.

9:1289

Potato bushes can be pollinated with sifted ash (preferably birch). About 10 kg of ash per 1 hundred square meters of plantings. (1 kg per 10 sq.m). After a day or two, not only the larvae of the Colorado potato beetle die, but also most of the adults. Together with organic matter, pour wood ash into the furrows. The soil, flavored in this way, is disastrous for the beetle.

9:1884

After hilling around each bush, sprinkle 1 tbsp. a spoonful of ash. When the stems rise by about 15-18 cm, the planting is sprayed with ash-soap infusion.

9:293

Gives good results spraying potatoes with an infusion of fresh walnut leaves. Leaves, fruits and walnut shells are used to combat the Colorado potato beetle. From autumn, fallen leaves are harvested and stored in a dry, ventilated place. 3-4 weeks before the mass appearance of the beetle, the leaves are soaked in a bucket (2 kg per 10 liters of water). Before use, the infusion is filtered twice.

9:1013

The Colorado beetle does not tolerate marigolds (this plant is also called calendula). Where potato beds are “circled” by a row of calendula, and additionally “stitched” diagonally by this flower, there is no pest, although neighboring plantings are affected by the Colorado potato beetle.

9:1502

Repel the Colorado potato beetle and beans planted next to potatoes. In addition, potatoes are more productive from such a neighborhood, and beans are not superfluous on the farm.

9:288

In the aisles of potatoes (or in the rows of bushes), plant sidun beans. These two cultures grow without interfering with one another. But bean beetles do not tolerate and leave the site.

9:602

In a bucket of water (10 l) dilute 100 g of birch tar. Spray plantings with a solution 3 times a week.

9:782

Good results are obtained by using a 4% solution of chicken manure (about 80 buckets per 1 hundred square meters). In the cases described, the beetle disappears for several years (up to 10 years). Processing should be carried out only after harvest.

9:1182

But it is easier and more efficient to plant nearby repellent plants: catnip, coriander, nasturtium, onion, tansy, horseradish, vegetable beans, white yasnitka.

9:1442

From moles

9:1474

10:1980

10:4

Old grandfather's, truly natural way. You have to be like an animal. They (mainly males) mark their territory to scare and warn their own kind. And we mark - with urine (male), pouring it into molehills. The effectiveness of the method exceeds expectations.

Throughout the site, in a spread of 2 - 3 m, we drive thin metal rods into the ground, empty beer cans, put them upside down. Any breeze, rocking the banks, creates a very unpleasant noise for the moles.

10:861

The surest way is to get a dog. People who have done so say they have forgotten what a mole is and how to deal with it. Apparently the dog also marks its territory with urine.

10:1186

Any bottle is dug into the ground, into the mole's hole at an angle of 45 degrees. The howling of the wind in empty bottles scares away this animal

10:1435

A good way is a piece of ordinary water pipe and a plastic bottle. Pieces of pipes are hammered into the ground so that their lower end is deeper than the level of the animal's moves. A pin with a diameter of 8-10 mm is hammered into the upper part of the pipe, reinforcing it in the center of the pipe with a wooden plug. A hot nail or metal pin is used to burn a hole in the bottom of the bottle with a diameter greater than the diameter of the pin. Cuts are made on the bottle along a solid line, and along a dotted line, the plastic is bent. There should be 4 such bends. At the slightest breath of wind, the bottle rotates, the hollow pipe resonates and creates noise that the animals are afraid of.

10:2539

But it is more effective to plant nearby repellent plants: castor beans, daffodils.

10:141

How to get rid of ants in the garden:

10:236

11:742 11:747

Loosen their nest and sprinkle with lime or tobacco dust;

11:868

Ants do not tolerate strong odors. On the anthill, you can put the head of a smoked herring, sliced ​​\u200b\u200bgarlic cloves into several parts, spread out tomato tops or parsley leaves;

11:1217

A decoction of tomato tops helps well. The more concentrated the solution, the better;

11:1376

Take corrugated cardboard about 20 cm wide, sprinkle it with a soot solution or powder it with cinnamon. Ants cannot stand the smell of soot and cinnamon;

11:1647

Not a very pleasant way, but you can water the nests of ants with urine, this often helps;

11:162

Make a solution: take ten liters of water, two glasses of vegetable oil, some cheap shampoo and vinegar. Poke a hole in the center of the anthill and pour this mixture into it. Close with foil for a few days;

11:576

Bring large red ants from the forest and settle in the garden, and after that the black ants themselves will leave your territory

11:805

Plant nearby repellent plants: Peppermint and spike, tansy, bitter wormwood, lavender, small valerian, peppermint and spike, tansy, bitter wormwood, lavender, small valerian.

11:1162

From cabbage fly larvae

11:1224

12:1730

12:4

Sprinkle the soil under the plants with ordinary wood ash, which has a double benefit for cabbage: it repels the cabbage fly, and it is a good fertilizer.

12:279

Exclusion from the crop rotation of radish, which most attracts cabbage flies.

12:422

To repel flies, sprinkle with naphthalene, after mixing it with sand in a ratio of 5-8 parts of sand and 1 part of naphthalene; instead of naphthalene, tobacco dust is used in a mixture with an equal amount of lime (300 g of the mixture per 10 m2).

12:842

You can also soak peat chips (200 g per bucket of peat) with creolin and sprinkle around the plants.

12:1028

In the fight against larvae, a tobacco solution is also used: 200 g of tobacco and 1 tbsp. a spoonful of soap in 10 liters of hot water. The drug is filtered and sprayed with plants and soil.

12:1330

Plant nearby repellent plants: garlic, marigolds, radishes, sage, wormwood, hyssop.

12:1505

From the carrot fly

12:46

13:552 13:557

You can prepare a spray solution from dry tomato plants. Pour 1 kg of dry mass into 10 liters of water, leave for 4-5 hours, then boil for 2-3 hours on low heat, dilute with water 2 times, add 30-40 g of soap per 10 liters of solution. The decoction retains toxicity to pests for a year when stored in a cool place.

13:1142

Sowing carrots in early or late periods in dry, unshaded areas. Sowing is important to do immediately sparse: then you do not have to thin out the plants, during which a strong smell of carrots appears, and a large number of flies flock to it.

13:1605

To scare away the carrot fly, the aisles are pollinated with ground hot pepper or ash.

13:166

Spray the soil and plants with infusions of black or red pepper (1 tablespoon per 10 liters of water), garlic, onion peel, marigolds, tomato tops, wild rosemary, spruce and pine needles and other odorous plants. But in order for the smell of these herbs to constantly stand over the carrot bed, it must be sprayed every three days.

13:731

Pour boiling water over crushed bitter wormwood. Infusion to process the beds.

13:874

Between the rows of carrots, especially in May and June, pest repellents are added: mustard, ground red or black pepper (1 teaspoon).

13:1149

It’s great if onions, garlic or tomatoes grow next to a bed of carrots.

13:1291

To protect crops from carrot flies, which cause a lot of trouble, on one side of the garden, place onions on a green feather, on the other - garlic;

13:1567

Plant nearby repellent plants: lettuce, leek, onion, rosemary, sage, tobacco, wormwood.

13:187

From wasps, hornets, gadflies, horseflies and bees

13:269

14:775 14:780

All of them are similar in many ways, and therefore the methods of struggle do not differ.

14:904

If a wasp, a bee or a gadfly flies up to you, remain calm, stay still, do not wave your arms or make sudden movements - this can provoke aggression.

14:1246

After bathing in the river, dry your body immediately, it attracts insects, as does sweat and various perfumes. They don't like strong odors.

14:1505

Lubricate exposed areas of the body with any cologne that has a little mint oil or mint drops added (5 drops per tablespoon of cologne). The tool works for about an hour.

14:335

You can make a trap for wasps. Take 250 ml of water, 4 teaspoons of honey and some vinegar. Heat water, dissolve honey, cool, add vinegar. Pour the solution into a dark glass bottle and place it near the place where the wasps roam.

14:784

If you find a wasp nest in or near the house, wait until it gets dark and the wasps gather in the nest, soak a cloth in turpentine, wind it around the end of the pole and plug the entrance tightly with it. Leave it like this for a day (But in my opinion, this is not humane!)

14:1242

If wild bees, wasps, hornets are trying to make their home near you, plant a bush of peppermint or plucked greens.

14:1477

But given that the benefits of wasps are not commensurate with the inconvenience of their neighborhood, it is best to contact a beekeeper. They know how to deal with them. In the evening, they fumigate, put a bag on the nest, cutting the nest to disconnect it and take it away to the forest. The bag is left untied along with the nest, hastily moving away. All this time you should be in a mosquito net, tight clothing and gloves.

14:2241

If this is a garden plot, plant repellent plants nearby: peppermint.

14:149

From mice

14:179

15:685 15:690

It’s not bad to prepare baits from vegetable oil, flour and gypsum, which will harden in the stomach of a rodent and cause death (I AGAINST daring!) A similar remedy: spread a mixture of alabaster and sugar (or flour) near the holes and put a saucer with water next to it.

15:1149

Rats and mice cannot stand the smell of mothballs and mint, which can also be used as a rodent control.

15:1381

Finely chop the cork and fry it in pork fat. Then throw the bait to the mouse holes. After eating the cork, the mice immediately die from the swollen mass in the stomach.

15:1676

Scatter hot peppers and dried chamomile flowers along the trajectory of the possible movement of rodents, scatter burdock thorns in the corners of rooms.

15:276

Quicklime is mixed with sugar and scattered in places where rodents are most concentrated. Mice and rats willingly eat the bait and soon die. Quicklime in the stomach is heated by the action of water and gastric juice, causing the death of the animal.

15:746

When using means of control such as mousetraps, it should be remembered that mice have an extremely acute sense of smell and will try to stay away from a mousetrap that their compatriot has landed in. Therefore, when re-installing the trap, you need to pour boiling water over it, and take the bait with gloves so as not to leave your smell on it.

15:1366

In the garden, plant repellent plants nearby: at home, where we keep food, lay out dry branches: wormwood, garlic, rank, daffodils.

15:1619

From apple honeydew

15:54

16:560 16:565

To destroy the larvae in the period from bud break to flowering, sprinkle the plants with infusion of yarrow, ash, tobacco, shag, soap solution.

16:847

Fledged psyllids and those that have returned to lay eggs can be destroyed by tobacco smoke. Pour 1.5-2 kg of tobacco waste on pre-prepared heaps of straw and fumigate for two hours for two plants inhabited by adult suckers. Fooled by the smoke, copperheads fall to the ground. Now it is important to immediately collect them from the ground under the plants, otherwise many will come to their senses and rise into the crown.

16:1553

Some gardeners use spraying with bitter pepper infusion (1 kg of fresh or 0.5 kg of dry red pepper per 10 liters of water). The infusion is boiled for 1 hour over low heat, then infused for 24 hours. The resulting concentrate can be bottled and stored in a dark, cool place. Before spraying, 125 g of concentrate and 40 g of laundry soap are added to 10 liters of water. Plants are sprayed with an interval of 10-15 days.

16:761

Plant repellent plants nearby: black henbane, common harmala, creeping mustard, vine clematis, medicinal dandelion, bittersweet nightshade, real tobacco, garlic.

16:1099

From nematodes

16:1132

17:1638

17:4

Arranging quarantine for new plants. Disinfection of dishes, tools (the simplest measure is scalding with boiling water). Sterilization of the substrate in a water bath at a temperature of +50-55C for at least 10 minutes.

17:365

After spraying the plants, allow them to dry quickly, at low temperatures, keep the plants in relatively dry conditions.

17:610

Nematodes are very sensitive to heat and can be killed by a 30-minute water bath at 45°C.

17:831

Among garden plants, everyone knows how hostile to nematodes, erect marigolds and asparagus. They can be planted in row-spacings or for the whole season they can occupy a plot intended for potatoes to destroy the pest.

17:1243

An effective preparation is well-made ripe compost. Therefore, where the soil is fertilized with compost, the risk of mass spread of nematodes is minimized.

17:1560

Plant nearby repellent plants: marigolds, calendula, erect marigolds, asparagus.

17:170

From codling moth apple

17:229

18:735 18:740

After the end of the collection of fruits - collection and destruction of the remnants of the packaging material; cleaning dead bark from boles and branches on old trees.

18:1015

Mulching between rows and minimal tillage in tree trunks.

18:1170

Satisfactory results are achieved by hanging on trees special pheromone evaporators (polyethylene and rubber tubes, rings, cords, paper tapes with a consumption of 20-100 g/ha of pheromone) in order to disorient males.

18:1600

To destroy the caterpillars of the first generation in the second decade of June, belts are placed on the boles of productive trees. They can be agile, requiring periodic review, and suicidal. For the manufacture of hunting belts, paper, gauze, burlap, matting and other materials are taken.

18:520

Most of the codling moth caterpillars gather under belts made of burlap and old cloth. Belts are applied at a height of 30-40 cm from the ground, they are looked through weekly, crawled caterpillars are selected and destroyed.

18:898

19:1407

Self-killing belts are imposed on trees no younger than 15 years old. For the preparation of belts, wrapping paper is used, cutting it 40-45 cm wide, and one of the longitudinal halves is impregnated on both sides with the composition of chlorophos - 1.5%, preparation No. 30 - 5%, earth - 50% and water - 43.5% . The belts, applied to the trees with the oiled side, ensure the death of the apple codling moth and other pests that have crawled under them throughout the season and do not require viewing.

19:2227

The fight against apple codling moth can be successfully carried out with an infusion of wormwood. For this, wormwood is harvested from the moment of its flowering, dried and stored in the attic. To prepare the infusion, finely chopped plants are placed in a cauldron (half or 3/4 of the volume) and poured with water; after a day, boil for 30 minutes, cool, filter through gauze and dilute with the same amount of water. Spray trees with an interval of 10-12 days.

This method is effective, and in combination with light traps, it allows you to save the crop without the use of poisons.

19:987

There is another way to deal with the apple codling moth. In the garden, immediately after flowering, hang jars of apple syrup seasoned with yeast. You can prepare it from apple juice of dry or green fruits, previously mashed together with the rotting part. Butterflies fly on such syrup and die in it.

19:1567

Plant repellent plants nearby: garlic, wormwood.

19:118

From slugs and snails

19:168

20:674 20:679

A good neighbor for strawberries is parsley, if you sow it with a border around strawberry beds, then they will not be afraid of snails and slugs.

20:934

Spread wet rags or burdock leaves between the rows of plants on which snails have become accustomed, in the morning the mucus will hide under their shadow, and you will go and collect them in the morning.

20:1249

Arrange saucers with dark beer for the night in the aisles of strawberries. Pour beer somewhere up to a height of 1.5 -2 cm so that the slugs drown.

20:1490

Sand and sawdust. Snails cannot crawl on sand and sawdust, so a sawdust and sand circle around the plant can be very effective.

20:1770

An ordinary cup of coffee will scare away pests and will not harm plants. USDA research staff in Hilo, Hawaii, tested caffeine sprays on houseplant-eating slugs. They noticed that a 1–2% solution of caffeine killed almost all snails and slugs in two days, while lower concentrations (about 0.01%) repelled them.

For comparison, a cup of instant coffee contains approximately 0.05% caffeine, coffee brewed from ground beans has even more. Coffee grounds can also be used as a snail repellent, but spraying with a caffeine solution is much more effective: slugs crawl away as soon as they come into contact with caffeinated soil.

20:1308

Caffeine can kill small snails and slugs, and scare large ones away from the garden. It is best to use caffeine for small gardens and plots. Unfortunately, it can act not only on snails and slugs, but also on beneficial insects. High concentrations (from 2%) can damage foliage and cause yellowing of plants.

20:1921

To kill snails (slugs), the surface of the soil should be sprinkled with freshly slaked lime powder, in the amount of 40 quarters per tithe. Sprinkling of the soil with lime is carried out in 2 steps in the interval of 10-15 minutes. At the first sprinkling, the snail is protected from lime by secreting mucus from itself, while at the second sprinkling, the snail is no longer able to excrete mucus, turns black and dies. Sprinkling the soil with lime in this way for two days in a row, in the morning, you can finally destroy all the snails.

20:888

21:1397

Sprinkle the earth in the evening or in wet weather with finely crushed iron sulphate mixed with sand. None of these animals will pass where iron vitriol is poured, since they die from contact with this substance.

21:1828

Hedgehogs, frogs and toads eat slugs and snails with great pleasure. True, in the conditions of our sites, quite often these natural enemies simply have nowhere to stumble, and therefore they bypass the gardens.

As for hedgehogs, there is definitely no place for them on 6 acres: it’s too crowded and noisy. And frogs and toads can be completely lured to your site by making some mini-shelters for them in the form of piles of leaves and branches, or even digging a small pond.

21:863

Perhaps the simplest remedy is to sprinkle (or, rather, pollinate) the aisles with lime after rain or watering, when the slugs begin to move actively. Getting on strips of lime, they burn their abdomen and die. You can take not pure lime, but mixed with ash or tobacco dust (1: 1). In the absence of rain, the soil is treated in this way late in the evening or at night, when slugs are on the soil or on plants.

Soil treatment is periodically repeated (after 7-15 days), which leads to the gradual death of mollusks.

21:1829

Plant nearby repellent plants: fennel, garlic, rosemary, parsley, oak bark.

21:160

From the scoop

21:189

22:695 22:700

Butterflies can be caught using fermenting kvass (dilute it 3 times and add some yeast). Jars with bait are hung in plantings. Butterflies can also be caught on fermenting molasses (bred 3 times, poured into bowls).

22:1137

To use an effective and harmless biological method for combating scoops - a Trichogramma predator that destroys pest eggs. During the laying period, carry out a three-time release of Trichogramma (30-40 thousand individuals per 1 ha with each release) with an interval of 5-6 days.

22:1629

Against caterpillars of younger ages of each generation of scoops, apply biological preparations: concentrated lepidocide, BA (biological activity) - 2000 EA / mg - 40-50 g per 10 l of water (1.5-2 kg / ha); bitoxibacillin, BA - 1500 EA / mg - 50 g per 10 liters of water (2 kg / ha). If necessary, re-treatment should be carried out after -8 days. (The working solution must be prepared immediately before the treatment of plants.

22:725

Caterpillars of younger ages can be destroyed with an infusion of wormwood. 1 kg of dried and crushed mass of wormwood is added to a small amount of water, boiled for 10-15 minutes, then the solution is cooled, filtered and diluted with water to 10 liters. Spraying of plants is carried out several times at intervals of 7-10 days.

22:1280

Plant nearby repellent plants: amaranth, oak bark, geranium, marigolds, kosmeya.

22:1435

From Medvedka

22:1471

23:1977 23:4

The best way to deal with this insect is to invite a mole to the charged area :). Moreover, the habitat of both is similar - both love light, soft soil, and the bear for the mole is a delicacy.

23:401

In areas infected with a bear, it is impossible to feed plants with fresh mullein - it will attract a pest from all over the area. Diluted bird droppings, on the contrary, scare away the bear (you need to water the ground with infusion of chicken droppings in dry weather).

23:859

Marigolds sown along the borders of the site block the access of the bear from neighboring territories - the bear does not tolerate the smell of marigolds.

23:1109

In autumn, when the soil temperature is not lower than +8 degrees, it is recommended to dig trapping pits 50-60 cm deep in the areas infected with the mole cricket (at least two pits are dug per 100 square meters of territory), covering the bottom and walls of the pits with an old film and filling the pits with semi-rotted manure - in them the bear climbs for the winter. With the onset of persistent frosts, manure with bears is scattered over the surface of the earth and the bears die from the cold. After the soil temperature drops to +5 degrees and below, the bears become inactive and mainly settle in a vertical course - this must be taken into account when making trapping pits, without postponing their digging until late autumn.

23:2345

In the spring, after mid-May, on the eve of the egg-laying period of the bear, it is recommended to dig shallow holes on the site and fill them with fresh manure or chopped straw, or simply lay out heaps of manure on the surface of the earth. Medvedki crawl into manure for laying eggs; the larvae hatching from the eggs do not leave the nests in heaps at first and feed on manure. After 3-4 weeks, the manure, together with the larvae, is removed and burned, or placed in specially equipped pits.

23:844

In the spring, before the emergence of seedlings of plants, baits are prepared for the bear from grains of corn, barley, rye, and wheat. It is important to prepare and lay out the bait just before the emergence of seedlings - otherwise the bears begin to feed on young plants and almost do not eat the bait.

23:1349

The grain is steamed until swelling and dusted with aldrin powder (50 g of powder per 1 kg of dry grains). Up to 0.8 kg of seeds are consumed per 1000 square meters, evenly distributing them over the soil surface, covered with a rake and watered. Zinc phosphide is also used as a poison (for 1 kg of dry grain - 50 g of the drug, adding 3% sunflower oil); mix thoroughly and close up to a depth of 3-5 cm. Medvedki find bait by smell, eat it and die. Poisoned insects are regularly collected from the surface of the earth and destroyed so that they are not pecked and poisoned by birds. (AGAIN CHEMISTRY!)

23:2423

In the summer, this method of dealing with the bear is also used: a few drops of sunflower oil are poured into the opening of the bear's stroke and 1-2 liters of water are immediately poured from the watering can. After a few minutes, the bear comes to the surface of the soil and dies.

23:446

Plant nearby repellent plants: marigolds, garlic.

23:554

From aphids

23:580

24:1086 24:1091

In addition to special preparations for combating aphids, which are sold in stores, various infusions are also used, which are prepared on the basis of available means. These methods of struggle are harmless, environmentally friendly.

24:1479

Soap solution. Dissolve 25-30 g of laundry soap in 1 liter of water (soft).

24:1620

Ash-soap solution. Pour 30 g of soft wood ash (or 15 g of hard wood) into 1 liter of hot water, bring to a boil, strain the solution and dissolve 25-30 g of laundry soap in it.

24:344

Dry mustard. 60 g of powder is brewed with a liter of water and insisted for three days in a tightly closed container, dissolving the infusion in three liters of water, spray the plant.

24:643

Infusion of wood ash: 3 kg of wood ash is poured into 10 liters of hot water, kept for two days, filtered and sprayed or washed with plants.

24:912

Ash decoction: 2-3 kg of wood ash is poured into 10 liters of water, boiled for 30 minutes, settled and plants are treated with a cooled solution.

24:1147

Infusion of garlic: 200-300 g of unpeeled garlic heads are finely chopped and poured with two liters of water. After a day, the mass is squeezed out, 8 liters of water and 20-30 g of laundry soap are added to the solution. For the treatment of plants, the prepared solution is diluted: 8 liters of water are added to two liters of the solution.

24:1657

Infusion of onion or garlic. 100 g of onion peel or 75 g of finely chopped onions or garlic, insist under a lid in 5 liters of water during the day, strain. Spray 3 times at weekly intervals.

24:352

Tobacco infusion: 400 g of tobacco or shag are infused in 10 liters of hot water for two days (you can insist for a day and then boil for 2 hours). Before spraying, the infusion is filtered, if boiled, it is diluted with water (1: 1), and 30-40 g of laundry soap is added.

24:807

Infusion of potato tops: green, disease-free tops of 1-2 kg are infused for 3-4 hours in water (the tops are placed tightly in a container and poured with water to cover the tops). Use freshly prepared infusion.

24:1216

Coniferous infusion: 200 g of pine or spruce needles are crushed, poured with 2 liters of warm water, insisted for 6 days in a tightly closed container, then squeezed and filtered. Before processing, dilute with water up to 20 liters. Plants are treated with an interval of 3-7 days.

24:1683

Pepper infusion: 1 kg of raw or dried peppers are boiled for 1 hour in 10 liters of water in a sealed container. Insist for two days, filter. To treat plants, 0.5 l of infusion is diluted with 10 l of water and 40 g of laundry soap are added.

24:401

Infusion of citrus peels: 100 g of dry tangerine, orange or lemon peels, pour 1 liter of warm water and insist under the lid for 3 days. How to use: Spray the plant as needed.

24:772

Tar soap - 40 g of soap per 1 liter of water.

All infusions are designed for a large number of plants and a huge amount of water. But these proportions can always be converted to the amount you need.

24:1123

Aphids are eaten by adults and ladybug larvae, hover flies, lacewings, and several species of wasps. To naturally attract these insects, as well as birds, to your garden, plant fragrant herbs, nettles, and green manure.

24:1573

Plant plants that are attractive to aphids away from crops that you want to protect against these pests. Aphids especially love nasturtium, cosmea, sleeping pills, mallow, tuberous begonias.

24:367

Kalina and linden are favorite aphid trees. Never plant valuable aphid-attacked crops in the vicinity of these trees.

24:623

Some plants repel aphids. Among them are traditional onions and garlic, as well as Dalmatian chamomile.

24:817

Plant nearby repellent plants: catnip, coriander, chives, fennel, garlic, marigolds, mustard, nasturtium, mint.

There are 4 main methods of pest control: agrotechnical, mechanical, chemical and biological. Agrotechnical method pest and disease control is mainly to prevent their occurrence.

With the help of various measures, the resistance of plants to adverse environmental factors is increased. The choice of soil plays a significant role in growing plants.

It should be remembered that in each region the composition of the soil is different, in addition, the quality of the soil on the site is determined by many factors: nutritional value, duration of use, location of groundwater. All these indicators should be taken into account when laying the garden, then the plants will be healthy and give a good harvest.

Before planting plants, it is necessary to determine the level of groundwater. If groundwater is located close to the soil surface, it is not recommended to grow plants with a deep, powerful root system on the site, as they will freeze slightly.

Experts recommend alternating horticultural crops on the site, as this prevents the occurrence of many plant diseases. In addition, the timing of planting in open ground plays an important role in the stability of plants. Plants planted ahead of time are usually weaker and more often affected by pests.

The increased resistance of plants to pests largely depends on the correct and timely care, the application of the necessary fertilizers and the loosening of the soil.

Some pests move to cultivated plants from weeds, so it is necessary to weed the site in a timely manner, remove fallen leaves, mowed grass and other plant waste.

If, despite the agrotechnical measures taken, horticultural crops are still damaged by insects, then in this case it is recommended to use a mechanical, chemical or biological method of pest control.

Mechanical pest control consists in the direct destruction of eggs, larvae and adult insects. At the same time, various activities are carried out: insects are removed from the branches and leaves of garden crops, winter masonry and spider nests are destroyed, and trapping belts are used.

Many gardeners place special traps on the garden plot in order to prevent the penetration of rodents and rats into the garden. The most effective method of mechanical pest control in combination with the use of other methods.

Chemical control of pests and diseases used when other means have not brought the desired result or if pests have spread throughout the site.

The following chemicals are used: insecticides - preparations intended for the destruction of insects; fungicides - drugs necessary to combat viral and fungal infections; acaricides - drugs that prevent the appearance of ticks in the garden; nematicides - preparations intended for the destruction of nematodes; molluscicides - drugs that prevent the appearance of slugs in the garden; zoocides - preparations intended for the extermination of rodents; herbicides are drugs used to control weeds.

In addition, drugs are divided according to the degree of impact on pests into intestinal ones, which contribute to their poisoning and death, and contact ones, which cause paralysis of the nervous system and cessation of breathing in rodents and insects.

With the chemical method of pest control, it is necessary to accurately calculate the amount of the drug used and make sure that the agent used is evenly distributed on the branches and leaves of plants.

Do not use excessive amounts of chemicals when processing plants, as this causes damage to the leaves and deterioration in the taste of the fruit.

In addition, uneven treatment of plants with chemical preparations leads to the fact that not all pests are destroyed, conditions are created for them to get used to this agent and form insecticide-resistant species.

Application biological pest control contributes to the preservation of the natural balance in the garden. Many pests have natural enemies, such as insectivorous birds, bats, hedgehogs, frogs, lizards, which prevent their spread and regulate their numbers.
