Subtleties of treating cucumbers against diseases using folk remedies. How to process cucumbers in a greenhouse How to process cucumbers if they are sick

The fight against diseases and pests of cucumbers is one of the main concerns of summer residents who practice growing this vegetable on their own plot. Our material today is devoted precisely to this topic.

More than 70% of summer residents who garden on land plots grow cucumbers and other popular crops. Site selection, seed preparation, soil fertilization and long-term care are just a small list of the concerns that are necessary to obtain good results at the end of the season. But all of them can be crossed out at one moment, and the cucumber bushes in the garden, on a net in the open ground or on a trellis in a greenhouse will not have the long-awaited fruits or their quality will be very spoiled. This may be the case if the crop is attacked by pests, or if it is infected with certain diseases. Naturally, there is very little desire to lose the harvest, especially at the moment when the cucumbers began to bloom and showed the ovary. Therefore, you should take extreme measures and fight for your rights to tasty and aromatic fruits that are needed for fresh salads or canning.

Prevention of diseases and pests

Even at the moment when you are just thinking about planting this crop at your dacha this season, you must simultaneously take preventive measures that will not only help save cucumbers from pests and diseases, but can also prevent them. A small list of requirements, on which you will not spend much time, will save not only the plants and the quantity of the harvest, but also its quality, especially if you are dealing with varietal crops.

• Only high-quality seeds that have been prepared and disinfected should be planted in the ground.
• Prepared seeds should be sown only in well-warmed soil. The minimum temperature at a depth of 8-10 cm should be at least +12+14°C.
• It is customary to plant cucumbers only in high-quality soil, clean, loose, fertilized, and fertile.
• In order for the bushes to suffer less from various diseases, it is necessary to choose varieties that are resistant to them.
• It is imperative to remove all plant residues from the garden bed, regardless of what crop they belong to. It would be most correct to burn them outside the territory of the summer cottage.
• Don’t forget about weeding, because weeds not only interfere with the growth and ripening of cucumbers, but are also carriers of many infections.
• You should be very careful with planting and care, and observe crop rotation.
• It is imperative to destroy diseased plants in and around the garden bed as much as possible, as well as catch and destroy pests that just appear in the planting area.
• Proper soil fertilization, application rates and frequency, as well as soil disinfection if cucumbers are grown in a greenhouse are also important.

Remember, it is much easier to carry out timely prevention and thereby preserve the harvest than to constantly treat plants and waste time trying to get rid of pests in vain.

Diseases and pests of cucumber (video)

Fighting cucumber diseases

Powdery mildew

This is the most common disease, not only of cucumbers, but also of many other crops. It affects the deciduous part of the plant, a little less often signs can be found on the stems and petioles, and even less often on the fruits. The cucumber appears on the top of the leaf as a small white spot, which gradually covers the entire leaf, and then the entire plant. Over time, whole lashes fall off from the common bush, which are already colored brown. The plant gradually dies, and if it continues to grow in a diseased state, the quality of the fruits noticeably decreases and the quantity decreases.

This disease is promoted by high humidity and constant temperature changes, dense planting, and weeds inside the bed. It also develops well when watered with cold water, due to winds and drafts, and also if summer residents choose the same place for annual planting. The disease remains in the soil, on weeds, plantain, and also on affected plants left in the garden bed during the winter.

Fighting the disease

There are many ways to combat this cultural disease:

• It is necessary to plant only strong and resistant varieties and hybrids;
• At the first signs of the disease, the affected parts of the plant are torn off and disinfected or burned;
• If the bush continues to hurt, it is treated with ground sulfur powder (about 25-30 g per 10 m2 of planting) or colloidal sulfur solution (0.3% sulfur, 25-30 g per bucket of water);
• Spraying with mullein is also considered effective;
• To prevent the disease from affecting the crop in the next season, it is necessary to get rid of plant debris and carry out deep digging of the soil of the bed;
• If powdery mildew has just been noticed on cucumbers, it is necessary to increase the potassium fertilizing rates;
• If the disease continues to spread and endanger the entire garden bed, you can use toxic chemicals - Topaz or Oksikhom, strictly according to the manufacturer’s instructions.

Downy mildew (downy mildew)

This disease easily destroys entire cucumber fields if you do not pay attention and help the crop in time. Downy mildew manifests itself as yellow-green spots with a light green coating, which immediately attack the upper parts of the leaf. The spots can be of various shapes; they quickly spread to all plants, forming a purple coating on the lower part of the leaves. Most often, the disease appears in mid-July (in greenhouses and in June) and quickly affects not one plant, but also all neighboring plantings.

Downy mildew of cucumbers spreads due to condensation, high environmental humidity, temperature changes at night and day, due to cold watering, morning cold dew and fog. It spreads very quickly, as it is even carried by the wind.

Fight against peronosporosis

• Treatment of seeds before planting, heating and disinfection with a solution of potassium permanganate;
• Planting occurs only in warm and healthy soil; waterlogging is not allowed. Watering young plants only with heated water, mandatory fertilizing at all stages of crop cultivation;
• If the disease is already present in the garden, the plants are treated with a milk solution (1:9 with the addition of 10 drops of iodine for every 10 liters), also with a urea solution (no more than 1 g per 1 liter of water);
• You can also treat with a solution of Bordeaux mixture;
• If the disease has been noticed in the garden bed, we recommend not planting cucumbers in this area for about five years;
• If you cannot cope with downy mildew, we recommend treating the cucumber bushes with chemicals.

White rot

This disease quickly spreads throughout the plant, covering the foliage, stems, tendrils, and even flowering and ovary. All parts of the plant are covered with a kind of mucus and plaque.

White rot thrives in greenhouses where there is high air humidity, air stagnation, high density of plantings, and temperature changes. Remember that pathogens remain in the soil for a long time.

Fighting the disease

• First of all, they level the agricultural technology to the proper level, also balance the humidity and temperature, make the plantings more sparse and weed-free in the garden bed;
• Diseased parts of plants are carefully cut off and burned outside the dacha, and the wounds after cutting are powdered with lime or ash;
• The greenhouse or soil near the bed is completely disinfected, and the plants are also fed (2 g of copper sulfate and 10 g of urea per bucket of water, spraying consumption - 1 liter per 10 m2).

Root rot

Root rot can affect seedlings and even adult plants, regardless of where they are planted. Part of the root of the bush dies off, the entire root system and the neck of the plant begin to get sick, the stem becomes thin, and the plant slowly dies. Root rot “burns” the root, and the stem becomes rotten.

The disease spreads due to improper sowing (poor quality seeds, cold soil), cold watering, heavy soil, high humidity, and temperature fluctuations. The infection can remain for a long time in the soil of the garden bed and on the remains of diseased cucumber bushes.

Fighting the disease

• Water only with warm water, not at the root;
• Treating the lower part of the bush, cleared of soil, with chalk or fresh sawdust, sand or peat;
• Normalization of environmental temperature and humidity, timely removal of weeds;
• If the plant is sick, its affected parts should be removed from the garden bed. If the bush begins to wither, it should be completely removed from the territory of the dacha;
• The cuttings should be powdered, the soil should be disinfected, watering should be moderate for a while, the bed should be dusted (at any planting site) with dry bleach (about 150-200 g for each square meter of the bed, and be sure to cover it with a rake);
• After detecting the disease and taking measures - removing diseased plants from the garden and disinfecting the soil - all boxes, trellises, guy ropes, tools, etc. should be washed with powder.

Anthracnose

The disease manifests itself as large round yellow-brown spots on the cotyledons and foliage of the plant; due to increased humidity, the plant becomes covered with a pink coating. The plaque spreads throughout the plant, concentrates in some places, forms small sores and kills the cucumber bushes. They quickly darken and the fruits wrinkle. The severity of the disease increases with increased humidity, dew and rain; anthracnose quickly spreads to the root system and destroys the plant. After this, the infection can be transmitted through plant debris and seeds.

Fighting the disease

• It is required to sow only healthy seeds and only in well-prepared, heated soil;
• Every year, properly cultivate the soil, destroy plant residues and weeds, and correctly change crops;
• If you discover a disease, we advise you to immediately treat the plants with Bordeaux mixture (4-5 days before harvest, every week) or a suspension of bleach (35-40 g per bucket of water, 20 days before harvest, every 10 days) ).

Cladosporiosis (olive spot)

This disease affects cucumber fruits and only in rare cases the stem and foliage parts. They become covered with small but numerous watery spots that grow and become hard. At this moment, the skin cracks, the fruit becomes crooked, the leaves become deformed, and the ovaries die.

Olive spot spreads through the air and can infect crops during rain or when watering.

Fighting olive spot

• Try to choose disease-resistant varieties for planting;
• If the cucumber is grown in a greenhouse, reduce the ambient humidity;
• Treat plants with Bordeaux mixture, its 15% solution, as a preventive measure;
• Be sure to fertilize with potassium sulfate.

Cucumber pest control

melon aphid

Finding melon aphids on cucumbers is not a problem. Small insects that destroy everything in their path are located from the bottom of the leaf and attack flowers, ovaries and fruits. During the period of its active activity and reproduction, leaves fall from the plant, flowers fade, and the yield decreases sharply. If during the period of aphid attack there is wet weather, the plants often cannot be saved at all.

Fighting melon aphids

• It is necessary to promptly remove plant debris from the site and try to destroy weeds;
• It is also necessary to observe crop rotation, dig up the soil in the fall, and disinfect the soil;
• If aphids have already appeared on the plants, spray with fermented grass (leave 1 kg of grass all day in a bucket of water), or spray with an ash solution (200 g of ash and 50 g of planed soap per 10 liters of water);
• Substantial colonies of melon aphids are removed from cucumbers using Inta-Vir according to the instructions.

Spider mite

Spider mites live on the underside of cucumber leaves and feed on its greens. A small red-green sucking insect is very dangerous for cucumber bushes, especially in greenhouses. By damaging the plant and entwining leaves with small cobwebs, the mite destroys entire beds, especially in hot weather, when the number of individuals increases significantly.

Fighting spider mites

• The first thing you need to remember is proper soil moisture and, if over-moistened soil is favorable for many diseases or pests, then for spider mites the element is over-dried;
• It is imperative to clean the soil in greenhouses and disinfect it;
• An infusion of garlic or onion (200 g of peel per 10 liters of water) and periodic spraying, 4-5 times throughout the season, cope quite well with tick colonies;
• Also, you should constantly monitor the cleanliness of the bed, the ambient temperature (if the cucumber is grown in a greenhouse);
• To destroy spider mites on cucumber bushes in a natural way, you can plant dill nearby, the flowering of which attracts ladybugs - the enemies of many plant pests.

Ants

On the one hand, ants are useful for the dacha area, but on the other hand, they dig many underground passages, besiege some plants, and also bring aphids to the plants.

Insect control

• You can fight ants using special traps - bottles with sweet syrup;
• It is necessary to loosen the soil in cucumber beds more often;
• If you notice ant nests, they are dug up and filled with kerosene;
• You can remove ants by dusting the soil with slaked lime or ash, as well as pouring boiling water over their nests.

Slugs

The main activity of slugs occurs at night, when they, not afraid of daylight, devour cucumber greens and spoil the fruits by eating the pulp. Also, slugs spoil the quality of the crop with traces of mucus and dark droppings.

Fighting slugs

• You can fight slugs in cucumber plantings by pollinating the soil with ash, slaked lime, and constantly digging up the soil;
• It is imperative to ensure the cleanliness of the area and the removal of plant debris;
• A good method for fighting slugs is to lay out special shelters around the area, under which the slugs will gather in the morning (burdocks, rags, boards, pieces of cardboard). You can also always treat the beds with Metaldehyde.

Whitefly

A fertile insect of very small size that moves quickly through the air, but loves to produce larvae on the lower part of cucumber leaves. The larvae are voracious and constantly suck plant sap, thereby causing the development of sooty fungus on the foliage and inhibiting the plants. It is very difficult to fight whiteflies, especially in greenhouses.

Pest control

• It is difficult to remove whiteflies due to their high fertility, but the methods of controlling them are quite simple. They involve spraying or washing off insect larvae from the leaves of the plant. Next, you should slightly loosen the soil in the garden bed and sprinkle it with humus or peat;
• The fight against whiteflies is also possible with the help of tobacco, which is planted along the perimeter of the cucumber bed. When whiteflies collect on a plant, it is treated with Inta-Vir.

It is necessary to know not only the peculiarities of the agricultural technology of this plant, but also diseases that can cause irreparable harm to the plant and destroy the entire crop.

Varieties of cucumber disease

Diseases that affect cucumber vines at different stages of its growing season can be divided into three groups.

1. Fungal diseases.
2. Bacterial diseases.
3. Viral diseases.

Fungal diseases of cucumbers

The most common fungal disease of cucumbers is powdery mildew. The reason for its appearance on the leaves is sudden changes in temperature, excess nitrogen in the soil or. Sick plants are covered with white powder, lag in growth and gradually dry out.

Downy mildew or peronosporiasis occurs as a result of high humidity, watering with cold water, and a sharp change in temperature. First, brown spots appear on the leaves, which dry out after a few days. Fungal spores remain on the back of the leaves. They are carried by wind and pests to neighboring areas. The disease occurs from plant debris or seeds infected with the mycelium of the fungus. The disease is provoked by high humidity and watering with cold water, as well as sudden changes in day and night temperatures. It appears during the fruiting period.

Dangerous fungal diseases of cucumbers should also include white rot, olive spot, and root rot.

Bacterial diseases of cucumbers

The main signs of bacterial wilt (caused by Erwinia tracheiphila) are:

• sudden wilting of the plant;
• the appearance of a white sticky mass (similar to saliva) that is released from the stem;
• leaf spotting and wilting.

The virus remains on the remains of the stem until next year. If signs of bacterial wilt are noticed, then all dry stems must be burned. Planting melons and melons in this area is contraindicated for 5-6 years. Seeds collected from such plants are also carriers of the disease.

The causative agent of wet rot is the bacterium Pseudomonas burgeri Pot. The source of infection is untreated infected seeds. Often the disease proceeds slowly and begins to progress only with a decrease in air temperature. The owners complain about a bad variety or freshly harvested seeds, because the shortfall in yield due to this disease can be as much as 40%.

The first signs of wet rot:

• slow shoot growth;
• wilting and drying of the lower leaves;
• a large number of barren flowers;
• the shape of the fruit is ugly;
• watery skin of the fruit and oil spots on the leaves;
• rapid loss of turgor in the afternoon;
• softening of stems and browning of blood vessels;
• brown mass inside the cucumber pulp.

Cucumber diseases spread very quickly in high humidity. Greenhouse plants suffer the most from this virus.

Angular leaf spot causes the death of cucumbers in a short time and is considered the most dangerous disease, as it is quickly transmitted from one plant to another. The infection is spread by wind, water droplets, pests and contaminated seeds. The disease is characterized by the appearance of brown spots on leaves and fruits, which dry out the tissue over several days. The bacterium multiplies most quickly in warm, humid weather.

When affected by vascular bacteriosis, the fruits lose their taste and commercial qualities. They are unsuitable for food as they turn wooden. The infection spreads through contaminated seeds and plant debris.

Viral diseases of cucumbers

Viral diseases of cucumbers are characterized by a change in leaf color. Spots appear on it that resemble a mosaic, and the leaf blade itself curls and wrinkles. All viral diseases are seed-borne or pest-borne. Before planting, it is recommended to warm the seed at a temperature of +70 degrees for three days.

Cucumber mosaic appears 25-30 days after planting on young leaves. The leaf becomes spotted with yellowing and becomes deformed. If you do not start fighting the disease, then within a few days the fruits will become infected. The carrier of cucumber mosaic is aphid.

White mosaic on cucumbers appears in the form of white and yellow star spots. Often the entire leaf turns white, and the fruits are painted with white stripes. A plant can be infected with the white mosaic virus only by contact and seeds.

Green mosaic can be confused with an ordinary type of fungal virus, but it only affects young leaves. Blister-like growths, mosaic yellowing, and wrinkling appear on them. Plants grow poorly, the ovary dries and crumbles.

How to deal with fungal diseases of cucumbers?

The most successful fight against disease is the absence of disease. Preventive measures will help achieve this result. What do we have to do?

• Observe .
• Maintain regular watering with warm water.
• Loosen the soil.

In the fight against fungal diseases, spraying cucumbers with infusion of mullein and marigold has worked well.
When infected with powdery mildew, drugs such as “Topaz” and “Qudris” are very helpful. "Oxychom."

If the first signs of downy mildew disease are noticed, then it is necessary to stop and spray the plants with a solution of potassium permanganate or whey tincture. In the acute phase, such drugs as “HOM”, “Kuprosat”, “Ridomil Gold”, “Polycarbacin” help. These drugs have an excellent effect in the fight against root and white rot, olive spot.

Ways to combat bacteriosis in cucumber diseases

Bacterial diseases are the most common and every gardener needs to know the main rules for protecting plants from viruses of this group. Preventative work allows you to protect young plants at the initial stage of their growing season.

• Preliminary treatment of soil against painful bacteria.
• Disinfection of seeds before planting (soak for 12 hours in a dark solution of potassium permanganate).
• Regular weeding and removal of their remains from the garden bed.
• Control of pests that are carriers of infection.
• warm, settled water: pour water into the furrows, and not under the root of the plant.
• Spraying cucumbers against pests.
• Compliance with crop rotation: return cucumbers to their place only four years after melons.
• In a greenhouse, the occurrence of bacterial diseases is directly related to the formation of condensation. To avoid large amounts of dripping moisture during periods of temperature fluctuations, it is necessary to use room heating at night.

What if it was not possible to protect the plants from infection? How to treat cucumbers against diseases in order to preserve the harvest? Copper-containing preparations will help: “Kuproksat”, Bordeaux mixture. Treatment must be carried out twice, with an interval of 10-12 days.

Fighting types of viral mosaic

The best way to combat viral mosaic is prevention.

• Before planting, soak the seeds in disinfectants or warm them at a temperature of +70 degrees.
• Destroy all plant debris in the garden after harvesting.
• Control aphids and other insect pests.
• Disinfect consumables.
• Water the furrows with warm water.
• Tie the plants to a support.
• Monitor the quality of the soil.
• Discard diseased plants.

These rules will help avoid infection with viral mosaic, but if the plant is sick, you should not immediately resort to chemicals. Tinctures made from onion scales, dandelion, tobacco, and garlic will help cope with the problem.

To know exactly what virus you are dealing with, you need the help of an agronomist. You can use the Internet or books on vegetable growing, which show cucumber diseases in pictures and describe the characteristic signs of each type of infection and how to combat them.

Video about cucumber diseases

Having decided to grow, whether for yourself or for sale, it is important to remember that it is better to prevent problems from occurring than to deal with the consequences later. Knowledge of the rules of agricultural technology and the correct treatment of cucumbers against diseases will help even novice gardeners to get the desired harvest.

Iodine treatment

Treatment of cucumbers with iodine allows you to cope with the following problems without the use of chemicals:

Use of wood ash

It is a natural alkali, which not only has fertilizing functions, but is also capable of killing harmful microorganisms and. Ash is an excellent helper in the fight against various types of cucumber spots that appear as a result of bacterial growth.

For prevention, it is recommended to lightly sprinkle the plant leaves with an ash solution in the early stages of microorganism development. A similar solution and iodine for cucumbers will help slow down the development of powdery mildew, which leads to the appearance of spots and white coating on the leaves. In addition, all this will avoid the intervention of chemicals.

To improve the adhesion of the drug, you can add laundry soap to the solution; 50 g of soap per bucket of water is enough. fertilizing increases the resistance of cucumbers to. In order to scare away and make it difficult for them to move, the soil is treated with ash or a mixture of this substance with tobacco dust.

Spraying with garlic solution

Garlic infusion is effective not only against aphids, but also other pests.

A similar solution can be prepared using two recipes:

• Take cloves in a volume that fits in a liter jar. Combine them with 0.5 liters of purified vegetable oil and 30 ml of liquid soap. The garlic is thoroughly chopped beforehand. The resulting composition is infused for 24 hours, after which it is filtered. For spraying, take 20 ml of the prepared solution and dilute it in 500 ml of water. The diseased plants are thoroughly mixed and treated. In order not to harm the plants, it is important to strictly observe the concentration.

Important! To obtain a good and high-quality harvest, even an unpretentious cucumber needs help. Do this using folk recipes or chemical elements- you decide.

• The second recipe consists of the same amount of garlic, 1 liter of water and 15 g of soap. The garlic is passed through a meat grinder, poured into a 2-liter jar, and the rest of the container is filled with water. Then, sealed, stored in a dark place for 12 days. After time, filter and use as intended. Before use, the resulting composition is diluted with water and a small piece of soap is added. For the correct concentration, 50 ml of garlic infusion is diluted in a bucket of water. Shake everything thoroughly and spray the plants.

Such spraying can be carried out as many times as necessary.

Milk serum

When plants begin to get sick during the harvest period, chemicals should not be used. At this time, in addition to iodine, cucumbers are also treated with milk and its processing products, for example, whey. It contains monoacid bacteria, which suppress the activity of pathogens of fungal diseases and saturate plants with useful substances.

The medicinal composition, which forms on the leaves of plants in the form of a thin film, protects them from the ingress of fungal microorganisms. However, the disadvantage of this product is that the effect does not last long, so you need to regularly treat the plants. Professionals recommend planning treatment for July, as this is when they are most vulnerable. The serum should not be used undiluted.

Before use, it must be diluted in the same amount with water at room temperature. Then the composition is heated to 25°C and the cucumbers are sprayed. Additionally, you can add laundry soap, this will help improve the adhesion of the product to the leaves.

Fertilizing plants with mullein solution

When affected by powdery mildew, which manifests itself in the form of a grayish coating on the entire bush and gradually leads to its death. The first manifestations of the disease can be removed by treating with an environmentally friendly fertilizer - mullein infusion.

It is prepared in several ways:

Take a certain amount of fresh water and fill it with the same amount of water. Leave for 24 hours, and after the time has elapsed, re-dilute in a ratio of 1:10. Stir thoroughly and water the prepared mixture between the rows at the rate of 10 liters of fertilizer per 1 m2. Use slurry and combine it with water in a ratio of 1:4. Leave in a warm place for 7 days. Then add more water in the amount of 3 servings and fertilize.

Important! An additional benefit from manure is the heat that will be released from the overheating of the manure. This will have a positive effect on crop growth.

Iodine and brilliant green

Cucumbers used to be often treated with brilliant green and iodine. The beneficial qualities of antiseptics are manifested due to the copper compound present in the composition. A solution based on iodine and brilliant green is prepared as follows: add 10 ml of brilliant green to a bucket of water.

How to spray cucumbers against diseases for a good harvest

A sufficient amount of sun, regular watering, fertile soil and the absence of pests and diseases are the key to a rich harvest of cucumbers. But often even experienced gardeners have questions about how to spray cucumbers against diseases, what preparations to use for feeding and in what quantities. Let's consider folk remedies that are used for the prevention and treatment of the most famous cucumber diseases.

Treatment of cucumbers against diseases

Cucumbers are most susceptible to fungal diseases. Among them are powdery mildew, root and gray rot, and bacteriosis. The danger of these diseases is that they affect several vital parts of the plant at once, which leads to a decrease in yield or to the death of plants. Let's consider publicly available folk remedies that can be used for treatment and prevention.

Treatment with iodine for root rot

The causative agents of root rot are fungi that live in the soil and reproduce in high humidity. Rot manifests itself after planting seedlings in browning of the roots, yellowing of the lower leaves, and death of the ovaries. Regular pharmaceutical iodine will help to cope with root rot.

Treatment of cucumbers with iodine is carried out with a dilute solution: iodine is mixed with cool water in a ratio of one to two and the plant stems are lubricated 10-15 cm from the ground. Treatment is carried out every 3-4 days until the signs of the disease disappear.

Treatment of cucumbers with milk and iodine is considered effective. To prepare the product, take 1 liter of milk, kefir or whey, 1 tablespoon of crushed laundry or liquid soap and 30 drops of iodine per 10 liter bucket of water. Cucumbers are sprayed with the prepared solution once every 10 days.

Gray rot is a bacterial disease that affects all plant organs. It appears in the form of gray or brown spots, which increase in size over time and completely cover the leaves, fruits and stems with a gray coating. Large amounts of moisture contribute to the development of the disease. Kitchen soda helps to deal with gray rot.

Treatment of cucumbers with soda is carried out with a weak solution (75 g of soda is dissolved in a 10-liter bucket of water). Plants are sprayed every three days.

Treatment of cucumbers with trichopolum against bacteriosis

Bacteriosis of cucumbers or angular spot appears in conditions of high humidity in open beds and in greenhouses, manifests itself in the form of brown angular spots on leaves, cotyledons and fruits. The disease is especially dangerous during the flowering period of cucumbers.

To treat plants, spraying and watering with a trichopolum solution are used. For spraying, dissolve two tablets of the drug in 1 liter of water; for watering, use five tablets per 10-liter bucket of water. As a preventive measure, before planting, a Trichopolum tablet is placed in the hole, and a few days after planting, it is sprayed with a freshly prepared solution.

Treatment of cucumbers with brilliant green against downy mildew

Downy mildew or downy mildew is one of the most dangerous fungal diseases of cucumbers. The first symptoms most often appear during flowering and fruiting in the form of yellowish-green spots on the upper part of the leaf and a gray coating with a purple tint on the lower part. Over time, the spots increase in size and the leaves become brittle and crumble. As a result, the development of fruits slows down, already ripe fruits lose their taste.

The danger of downy mildew is that fungal spores can remain in the ground for several years and infect plants every year. For treatment, use brilliant green. Thanks to the copper contained in the preparation, the solution not only acts as an antiseptic, but also feeds the cucumbers.

The healing qualities of brilliant green

Few people know that damaged cucumbers can be stored. If the skin of the fruit is slightly damaged by a disease or pest, carefully treat it with brilliant green. If there is surface rot or mold, it must first be cut out. A wound treated with brilliant green is covered with a film and the fruit can be stored for several months.

Treatment of cucumbers with brilliant green is carried out with the following solution: 50 g of urea, 2 liters of whey and 10 ml of brilliant green are dissolved in a bucket of water (10 l), and sprayed once every 10 days. As a preventive measure, spraying is repeated three times a season after the start of flowering, once a week.

Feeding cucumbers

Cucumbers, like any plants in the garden beds, need fertilizing. We recommend using root fertilizers (adding nutrients to the soil, under the roots); their effectiveness is much higher due to the rapid penetration of substances into the root system. Foliar feeding (spraying) is important in preventing diseases and the spread of insects.

Feeding cucumbers with iodine

In addition to its powerful antiseptic effect, iodine, even in small quantities, accelerates metabolism and stimulates plant growth, increases the yield and taste of fruits, and promotes the accumulation of vitamin C.

To feed, add a few drops of the product to the settled water for irrigation. Watering cucumbers with iodine is also a preventive measure against the development of powdery mildew and root rot.

Iodine can be used with milk or whey. To do this, dissolve 30 drops of alcoholic iodine and 1 liter of milk in a bucket of water and leave to infuse. Watering cucumbers with milk and iodine is carried out every 10-14 days.

Feeding cucumbers with brilliant green

It is worth treating cucumbers with brilliant green not only when yellow or brown spots appear on the leaves of cucumbers, but also as a preventive measure. To spray, add 5 ml of brilliant green (the contents of half the bottle) to a bucket of warm water.

In addition to fighting diseases, fertilizing with brilliant green promotes the accumulation of copper in the soil, which is especially important for areas in swampy areas. This microelement improves plant metabolism, promotes the formation of chlorophyll, and accelerates fruit development. To prepare a solution, add 10 drops of brilliant green to 10 liters of cold water. Water the cucumbers once every 2 weeks after the first leaves appear.

Feeding cucumbers with soda

Baking soda is one of the most useful and affordable cucumber fertilizers. It protects plants from fungal diseases, microbes, insects, increases productivity and improves the taste of fruits.

Cucumbers are treated with soda to prevent the appearance of aphids and the development of powdery mildew. To prepare the product, add 1 tbsp to 5 liters of warm water. l. vegetable oil, 1 tbsp. baking soda and 1 tablet of acetylsalecic acid (Aspirin-S). Spray the prepared solution once a month after sunset or in cloudy weather, due to the likelihood of the plant getting burned.

Watering cucumbers with soda begins when barren flowers appear on the ovaries. To prepare the mixture, dissolve 2 tablespoons of soda in 10 liters of water and water the cucumbers once every few days.

Bottom line

Processing cucumbers with iodine, milk, soda and brilliant green is very popular due to the availability of ingredients and a wide spectrum of action. Few store-bought products can boast of simultaneously feeding and protecting against diseases. Using folk remedies in the right proportions will help you grow a magnificent harvest and save on the purchase of expensive drugs.
