Disease treatment for cucumbers


Growing cucumbers, it is necessary to pay special attention to the state of the soil, the level of humidity and temperature. Such actions will prevent various ailments. Prevention of cucumber treatment is particularly important when caring for seedlings.

Basically, gardeners struggle with plant diseases carried out using household formulations. In this aspect, they are guided by insignificant cost and increased effect of action. Some of them have a much better effect than commercial fertilizers. At the moment, effective recipes have been developed against each pest.

Professional Cucumber Cultivator Tips

When cucumbers have small flowers, a light shade and thin lashes when flowering, this means that the plant lacks nitrogen. In this regard, the question of how to handle cucumbers summer residents recommend using a mixture of mullein. Fertilizer can be prepared by taking 8 liters of liquid and 1 liter of mullein.

If the shape of the fruit is round, and nearby the stem the body is narrowed, then the fruit lacks potassium. Its deficit is replenished by the daily use of wood ash cultivated in water. On one cucumber bush will be enough one liter of solution.

After picking cucumbers, all beds must be cleaned of weeds. Their disinfection can be carried out using a solution of copper sulfate. These preventive measures will prevent crop from fungal and other diseases for several years ahead.

Preventive spraying of plants

Many gardeners are interested in the question of how to spray cucumbers to get high yields. For these purposes, perfectly suitable milk mixture with the addition of thirty drops of iodine. You also need to add three spoons of rubbed soap.

The resulting solution should be used 1 time in 10 days, until the fruit ripens. This mixture is universal against various pests and plant diseases.

In order to treat and protect cucumbers from fungal diseases, an ash solution that acts as foliar feeding of plants is effective. To prepare such a solution, it is necessary to dilute the sifted ash in 2 liters of boiling water with the addition of soap.

Soap is required to rub. In order to prevent such a solution is used once a week. With the appearance of obvious signs of the disease it is used in 2-3 days.

One of the excellent means for preventive measures is considered to be a mixture based on rye bread, 30 ml of iodine, as well as water. Experienced gardeners claim that if you regularly spray cucumbers with this solution, this will increase the yield. The fruits will ripen much faster.

How to deal with powdery mildew

A lot of trouble gardeners delivers mealy dew. Its manifestations are evidenced by white bloom on the leaves. After some time, the leaves become reddish color. If you do not take any measures, the leaves begin to turn yellow and dry. This leads to the cessation of fruiting cucumbers.

It is believed that spores of fungi, which remain in the soil from plants of last year’s crop, lead to this disease. It provokes the development of the disease overcast and rainy weather, as well as watering with cold water. To prevent the development of the disease, you can the following folk remedies.

Take the serum, which is diluted with water in a ratio of 1:10. Processing contributes to the appearance of a protective film on the plant. It is possible to add 10 g of blue vitriol to the serum (3 liters). This amount is required for dilution in 7 liters of water. Using tansy, nettle, wormwood (100 g of grass and one liter of water) will allow you to prepare an effective decoction.

Also good results are obtained using the infusion of mullein (1 l is taken to 3 liters of water). Infused for 3 days, and then the filtered composition is diluted in 3 liters of liquid.

Can be treated with ash solution. Good results can be obtained by treating cucumbers with the following composition: 4 g of soda, laundry soap and 1 liter of liquid. Treat plants should be in the evening.

Quite an effective remedy is an infusion prepared on the basis of finely chopped 30 g of garlic, which must be infused in a day in 1 liter of liquid. The resulting composition is diluted in 9 liters of water. With the appearance of new foci of the disease, the treatment is repeated. You can process plants and a solution of potassium permanganate.

Effective measures to eliminate white rot

A disease like white rot has the ability to damage plant leaves with a white patina. Professional gardeners recommend immediately begin processing cucumbers.

If this is not done in a timely manner, then the disease spreads to both the leaves and the stems. Such a plaque can cause the whole plant rotting. Pathology spreads quickly enough when plants are planted close enough to each other in the greenhouse and insufficient air circulation is observed.

At the first symptoms of the disease, it is necessary to disinfect the soil or the greenhouse in time. To do this, prepare a specially designed mixture. It is prepared using two grams of copper sulfate and ten grams of urea. All this must be diluted in ten liters of liquid. Before you begin to process the plants, the mixture must be shaken.

Elimination of brown spot popular methods

Brown spotting or leaf mold is considered a fungal disease. It can damage cucumbers. The first symptoms of pathology manifests itself during the flowering period of the plant. Light olive spots appear on the upper side of the lower leaflets. They become yellow as the pathology develops. On the lower side of the leaves there is a light gray bloom. Due to the pathology leaflets can dry out.

Especially the disease spreads with high humidity. This pathology can affect crops, both in greenhouses and in the open field. It is possible to treat the affected plant with copper-containing fungicides.

In order for the drug to adhere perfectly to the plant, a small amount of liquid soap must be added to its composition. You can replace it with dishwashing detergent. It is necessary to treat the plant against cladosporia in two stages. The interval between them should be from 7 to 10 days.

Effective measures to combat root rot

Such a disease affects plants due to regular abundant watering of plants with cold water. The consequence of the disease is high humidity in the greenhouse and significant soil temperature. Recognize the disease can be on small cracks. They are treated with an ash solution with the addition of 5 grams of copper sulphate.

If the disease is started, the treatment of cracks with activated carbon, dry chalk, ash will be effective.

Experienced gardeners recommend resorting to the use of folk remedies. So, the prepared mixture in a ratio of 1: 2 water and iodine process the stems of plants. Work this solution every 3-4 days. Effective use of infant formula (1 liter) with iodine (30 drops). All this is mixed with 15-20 g of chopped soap in 10 liters of water.

Spider mite and its treatment

No less dangerous infectious disease is a spider mite, which may have a specific color: yellow, brown, green. The pest (1-2 mm) is located on the back of the leaflets. He sucks the juice, leaving holes on the cucumbers.

A good remedy is garlic solution (50 g of minced garlic and 0.5 l of water). The mixture should infuse. Then it is filtered and mixed additionally with the same amount of H2O.

Good results are obtained using the composition based on chopped bitter pepper. It is poured with a small amount of water and languished on the fire for an hour. The resulting mixture is required to dilute in a ratio of 1: 3. Has also proven itself tobacco dust, which powders pre-moistened leaves.

The destruction of gourd aphid

A big danger for cucumbers is melon aphid. It can be dealt with using the following composition: five liters of water, two hundred grams of ash and ¼ of a bar of grated grated soap. The affected parts of the plant are wiped with a sponge dipped in the composition, and it is also applied to the soil near the bushes to scare away the ants.

The processing of the sheet works well, if you take 2 liters of H2O and 40 ml of 9% vinegar. In the evening, plants can be treated with a milk composition at the rate of 500 l of milk, 10 drops of iodine and 1 l of water. You can use 60 g of soda diluted in 10 liters of water.

Ways to prevent anthracnose

Basically, the disease threatens cucumbers planted in the greenhouse. Spores of the fungus spread at the affected areas of plants at an increased rate. They focus in circles. As a result, have the ability to merge. Spores are found in seeds obtained from infected fruit.

The disease can be effectively eradicated using a 5% solution of copper sulphate. After that you should apply honey, lime and coal. You can also make the treatment of plants Bordeaux mixture. These measures are taken 4-5 days before harvest at weekly intervals.

Used suspension of chlorine lime at the rate of 35-40 g per bucket of water. Processing 20 days before picking fruit at intervals of 10 days.

A mixture of iodine and Zelenka

Good results are obtained by processing cucumbers with green paint and iodine. In their composition there are copper compounds that adversely affect plant diseases.

Folk remedies based on antiseptics are easy to prepare. To do this, add 10 ml of zelenka to the bucket of water. After spraying, cucumbers will not become greener, but this remedy will definitely protect against diseases.

Wood ash application

One of the effective folk remedies for cucumber diseases today is wood ash. In addition, the ash eliminates pests and parasites, and also contributes to the growth of culture.

Wood ash will help defeat various types of vegetable mottles that develop under the influence of bacteria. Prevent the occurrence of the disease by spraying the leaves with ash solution. It helps to slow down the development of powdery mildew, which is accompanied by the appearance of spots and white deposits on the sheets. Ash solution will be better to stick to the culture, if you add a little soap into it. Treating the land in the area of ​​ash makes it difficult to move slugs on it.

Traditional methods of treatment of cucumber diseases help to avoid the use of chemicals.

Use garlic solution

Garlic infusion is effective not only from diseases, but from pests. Prepare it easy. There are 2 main recipes. According to the first, you need to chop the garlic cloves and place them in a liter jar, pour 0.5 liters of vegetable oil and 0.03 liters of liquid soap. The mixture should infuse throughout the day. To spray cucumbers, it is necessary to dilute 0.02 l of the solution in 0.5 l of water and stir until it becomes homogeneous.

According to the second recipe, the same amount of garlic cloves is taken (they need to be passed through the press), 1 l of water and 0.015 kg of soap. All ingredients are placed in a two-liter jar and pour water. The full jar is covered with a lid and placed in a dark place for 12 days. After this, the infusion must be filtered, and diluted with water before use.

When spraying with garlic tincture, it is important to strictly observe the recommended concentration. To do this, 0.05 liters of tincture must be diluted in a bucket of water. Ready vegetables are sprayed several times until the pests leave them.

Whey Spraying

If plants are sick during harvest, they cannot be treated with chemicals. It is advisable to solve the problem with iodine and milk, or at least serum. Its composition contains monoacid bacteria that can inhibit the activity of fungi and saturate the culture with useful substances.

As a result of applying the serum on the leaves of a vegetable, a thin film is formed that protects them from the ingress of fungi. However, the treatment of plants with serum has one major drawback - the short-term action. Therefore, such treatments should be regular.

It is desirable to process the culture in July, since during this period it is most weakened. Undiluted serum processing of the culture is prohibited. Before use, dairy product must be diluted with water in a ratio of 1: 1. The finished solution is heated to 25 ° C and only after that they can process the vegetable.

Feeding with mullein solution

Powdery mildew, which is characterized by the appearance of a gray plaque on cucumbers, gradually leads to their death. The first symptoms of the disease are easy to defeat with the help of natural supplements - mullein tincture. In addition, this fertilizer has been shown to improve crop growth.

It is very simple to prepare a healing solution: it is enough to dilute fresh manure in water in equal quantities. The solution should be allowed to stand for a day, then dissolve in a ratio of 1:10. The solution must be thoroughly mixed and poured over the rows between them at the rate of 1 bucket of fertilizer per unit area. Dung slush should be combined with water (1: 4) and left to warm for a week, then pour into a solution of water and feed the vegetable.

Iodine treatment rules

Treatment of cucumbers with iodine helps to save them from a number of diseases. In particular, iodine helps to defeat root rot. The causative agents of the disease live in excessively moist soil. The disease is accompanied by darkening of the roots, yellowing of leaves and falling off of the ovaries.

Effective treatment of root rot provides for lubrication of cucumber stalks with iodine solution (part of iodine into two parts of water). The procedure must be repeated several times.

The use of this folk remedy effectively against powdery mildew. You can get cucumber from this disease by preparing a mixture of 1 liter of milk and 10 drops of iodine, which dissolve in a bucket of water. The mixture should be sprayed plant and soil.

Onion Husk Infusion

What could be more harmless infusion of onion peel? But for aphids and ticks - death. You need to take half a bucket of onion peel (for example, I collect it during the winter), pour 10 liters of hot water (70 degrees) and insist for 24 hours. Separated infusion needs to be diluted in half and spray the plants every other day (only 3-4 times). By the way, such an infusion also feeds plants with a mass of extremely important trace elements.

Powdery Mildew Fight

I can offer the most affordable and most popular: whey. It is necessary to take 3 liters of serum and 1 teaspoon of copper sulfate, 7 liters of water. Spray abundantly.

I just want to note that downy mildew (peronosporosis) in recent years is not as common as at the end of the 20th century: they learned how to prevent the disease, to effectively deal with the lesions. Seed treatment, soil disinfection after cucumbers with copper sulphate (50 g per 10 l), etc. - preventive measures, but mandatory. A disease occurs after prolonged cold rains, due to sudden changes in day and night temperatures. If you did not observe such factors, you may have stimulated the development of the harmful fungus yourself by pouring cold water on cucumbers.

Cucumbers: basic information

  • Preventive measuresThis disease manifests itself first on the leaves and cuttings, and then affects the fruits, forming carnival spots on them, turning into ulcers that penetrate into the cucumber and change its color to a pale color.
  • You can slow down the disease or stop it with the help of such drugs as Aktara, Aktelikt.This fungal disease appears on the leaves as white spots, which are formed by the superficial mycelium of the fungus. For the sprouting of mycelium, a low temperature to 15-16gr is necessary. and high humidity for 3-4 days. You may notice that the disease appears within 2-3 days after or during cold prolonged rains.
  • The main activity of slugs occurs at night, when they, without fear of daylight, devour the greens of the cucumber and spoil the fruit, eating the flesh. Also, slugs spoil the quality of the crop with traces of mucus and dark droppings.Cladosporeceae cucumber - a disease of the plant that affects the fruit
  • Root rot can affect seedlings and even adult plants, regardless of where they land. A part of the root of the cucumber bush dies, the entire root system and the neck of the plant begin to fall ill, the stem becomes thin and the plant slowly dies. If we talk about the course of the disease, the root rot "burns" the root, and the stem becomes rotten.In order for the disease not to hit the plants in the next season, it is necessary to destroy the plant debris and carry out a deep soil digging of the beds,

But for cucumbers, it is no less dangerous than a regular mosaic, especially its more aggressive strain, which causes the symptoms of a white mosaic.
  • When sunny weather occurs abundant sporulation and spread of the disease. From individual spots, the leaves are covered with an almost continuous white bloom, later moving to the shoots, the leaves are deformed and dry.
  • You can fight with slugs in cucumbers by pollinating the soil with ash, slaked lime, constantly digging up the soil,
  • Melon aphids meet on the cucumber is not a problem. Crayons insects that destroy everything in their path, located on the bottom of the sheet, attacking flowers, ovaries and fruits of cucumber. During the period of its vigorous activity and reproduction, leaves fall off the plant, flowers wither, the harvest sharply decreases due to the weakening of the mother plant. If during the period of attack of aphids wet weather is observed, the plants often cannot be saved at all.

Root rot of cucumber spreads due to improper sowing (substandard seeds, cold soil), due to cold irrigation, heavy soil, high humidity, temperature fluctuations. The infection can remain for a long time in the soil of the garden and on the remains of diseased cucumber bushes.

  • The virus is very resistant and easily transmitted from plant to plant, stored in seeds, plant debris, and can even live on garden tools.
  • Cucumbers are susceptible to the disease during a period of sudden changes in temperature and low light. Calcium deficiency and excessive nitrogen content also make plants resistant to powdery mildew.
  • A good method to combat slugs is considered to be the layout of a section of special shelters under which slugs will be assembled in the morning (burdocks, rags, boards, pieces of cardboard). Also, you can always treat the beds of cucumbers with Metaldehyde.
  • Also, it is necessary to observe the change of plants, dig up the soil until the fall, disinfect the soil,

  • Features of care:
  • In the process of watering, see that the water gets only on the ground.
  • In order to prevent the occurrence of the disease should start with the seeds. Do not forget to leave them in zinc sulfate solution for a day. Next, planting material must be dried and you can land. A good effect is the treatment of cotyledons and leaves of the Bordeaux mixture.

The main preventive action is the observance of sanitary measures before planting and during the cultivation period. This application of crop rotation or replacement of soil in the greenhouse, watering with warm water without spraying, timely removal of dried leaves and affected areas.

Fighting gourd aphids

  • Of the chemical agents, these are the drugs Kvadris, Topaz, and Jet. Spraying is carried out both on the upper and lower parts of the leaves and shoots.

  • Cucumber Root Rot - A disease that quickly ruins a crop
  • Disembarkation occurs only in heated and healthy soil, over-wetting is not allowed. Watering young plants only with heated water, mandatory dressing at all stages of cucumber growing,
  • Do not forget about the weeding of plants, because weeds not only interfere with the growth and ripening of cucumbers, but also are carriers of many infections.

Plant genus:

When planting cucumbers, only a nutrient pot is placed in the hole. The stem of the plant does not touch, hilling is not carried out

Fighting slugs

  • This is one of the most common diseases of cucumbers in the greenhouse. Its main danger is that it can appear at any stage of plant development. However, most often peronosporosis occurs in August, during fruiting. The disease persists on the soil for a long period - up to 7 years.
  • Fitosporin-M
  • Another bacterial disease of cucumber, the main source of infection are seeds obtained from diseased plants. The disease mainly spreads in film greenhouses at high humidity with the formation of droplets covering the plants.

It begins with the formation of a different shade of brown uneven spots on the leaves of the plant, then the spots grow, become darker, even black, dry and fail, be it hardened. Later, the fungus infects the fruit, forming on them the depressed brown spots, extending deep into the cucumber up to 3-5 mm.

Whitefly control

  • Be sure to carry out cleaning of the soil in greenhouses and disinfection,
  • The disease of cucumber is manifested by large rounded patches of yellow-brown color on cotyledons and the deciduous part of the plant, but, due to increased humidity, the plant is covered with a bloom of pink color. The raid spreads around the plant, concentrates in some places, forms small ulcers and kills the plant. The disease quickly affects cucumbers, the bushes of which darken and the fruits shrivel. The strength of the disease grows with increased humidity, dew and rain, anthracnose quickly spreads to the root system and destroys the plant. After that, the infection can be transmitted with plant residues and seeds.

If the disease is already present on the garden, the plants are treated with a milky solution (1: 9 with the addition of 10 drops of iodine for every 10 liters), also with a solution of urea (not more than 1 g per 1 liter of water),

It should be very careful with planting and care, observe crop rotation.Cucumber

You definitely need to know how to treat cucumbers for diseases

How to make so that cucumber diseases do not make themselves felt? Use biologics! To begin with, the treatment of old, otblodonosivshih plants. Apply tools such as a mixture of disinfectants, fungicides and insecticides. You can stay on this version, as Aktellik, “Bayleton”, “Farmod-3”. Good effect give checkers "Fas" and "Climate".

The main features: the leaves turn brown and large oily spots are formed on them. The main cause of this cucumber disease is a sudden change in temperature or watering with cold water.

Root rot can both fungal and bacterial origin. The source of infection can be affected seeds and soil containing pathogens.

The disease manifests itself by the formation of angular gray spots on the lower leaves of plants. The spots have a Pancake week, and on the lower side of the leaf there is an accumulation of yellow drops in which the accumulation of bacteria occurs. When these drops are washed away, the disease spreads to other leaves and conquers more and more space. If you reduce the humidity, the drops dry up, and the spots turn black and fall through. The ingress of bacteria on the fruit leads to the formation of small ulcers and curvature of cucumbers.

The cause of the disease is mainly infected seeds collected from diseased fruits, the fungus is also stored on plant debris and in the upper soil layer.

- a difficult process, but if you take it seriously, and even carry out preventive measures, it can be greatly simplified. We recommend reading the article about the best methods of dealing with slugs.


As a preventive measure, it is necessary to observe crop rotation, warm up or pickle the seeds and use disease-resistant cucumber varieties.

If the disease develops on an adult plant, then in addition to the defeat of the leaves and stems, it also affects the fruits, especially at low temperatures. They bend, mosaic yellow spots appear on the green body of the fruit, sometimes the fruit dries out, becomes wrinkled, and the flowers do not develop.

Treatment methods

The fight against cucumber diseases is a whole “epic” of consecutive actions aimed, first of all, at preventing the occurrence of infections. It is better to tackle the soil, seeds and seedlings in advance than to poison the almost ready crop with pesticides. In the fight against diseases of tomatoes in the greenhouse will help this material.

  • To begin with, reduce watering and fertilizing for a week.
  • Votes, average:
  • At the first signs of the disease, spraying with Ridomil Gold, MC, Kuprosat is possible.
  • Prevention and treatment of cucumber mosaic.
  • The author: Valery Medvedev

Ants can be removed by dusting the soil with slaked lime or ashes, as well as boiling water over their nests.

Treat the plants with Bordeaux mixture, its 15% solution, as a preventative,

  • A complete disinfection of the greenhouse or the ground near the garden is carried out; plants are also fed (2 g of copper sulphate and 10 g of urea are used for a bucket of water, spraying consumption is 1 l per 10 m2.
  • If the plant continues to hurt, the shrub is treated with ground sulfur powder (about 25-30 g per 10 m2 of planting), or with a solution of sulfur colloid (0.3% sulfur, 25-30 g per bucket of water),
  • Ask a question for free
  • Attention, only TODAY!
  • Next is the treatment with the drug "Topaz" or "Oxyhoma".

Preventive measures

  • ​Грибковое заболевание огурца, возникающее вследствие резких перепадов температур с повышенной влажностью, часто проявляется от полива дождеванием холодной водой.​
  • ​В качестве предупредительных мер, старайтесь соблюдать севооборот, не допускать появление на грядке сорняков, высаживать огурцы в компостированный грунт, укрывать от возможных похолоданий. Не допускать появление тли, как переносчиков заболевания.​

Spraying of plants with mullein is also considered effective,

More than 70% of summer residents who are engaged in vegetable gardens on the territory of land plots grow cucumbers and other popular crops. Site selection, seed preparation, soil fertilizer and long-term care are just a small list of those concerns that the plant will have to achieve high results at the end of the season. But all of them can be crossed out at one moment, and there will not be long-awaited cucumbers on the cucumber bushes on the bed, on the grid in the open field or on the trellis in the greenhouse, or their quality will be very spoiled. Perhaps this is the case if the crop is attacked by pests, or cucumbers will be infected with certain diseases. Naturally, the harvest is very reluctant, especially at that moment when the cucumbers began to bloom and showed the ovary. Therefore, one should take extreme measures and fight for their rights to tasty and fragrant cucumber fruits that are needed for fresh salads or canning.
