Cucumber leaves turn yellow. How to feed cucumbers

Every second gardener faces the problem of yellowing leaves on the lashes of cucumbers, and, regardless of whether the crop is grown in beds or in closed structures. Factors causing spots on sheet plates ah, yellow edging of leaves, drying and withering of cucumber tops, a lot.

Knowing the main reasons that provoke the yellowness of the leaves will help the gardener avoid crop losses and extend the fruiting of the plantation for maximum term. To prevent problems in planting pumpkin culture, beloved by summer residents, there are a number of preventive measures, which will be discussed further. We will also touch on the topic of what to do if the leaves have already begun to turn yellow in order to preserve the cucumber crop.

Why leaves turn yellow on cucumbers: causes and methods for their elimination

Lack of light

Cucumber bushes, even when grown on supports, resemble the jungle. Not surprisingly, the lower leaves lack sunlight and turn yellow. This is normal. Just regularly remove the lower leaves and thin them out in the middle of the lashes for more permeability of the thickets to light.

Irrigation irregularities

For cucumbers, both a lack of moisture and its excess are detrimental. In dry summers, it is recommended to water the cucumber plantation every other day, moistening the ground to a depth of at least 30 cm. With a lack of water, the roots begin to look for it on the surface of the soil, which provokes their drying, yellowing of the leaves and existing ovaries.

Never water a plantation with ice-cold water from a well or artesian well, it must be preheated to a temperature of at least +24°C. Water under the root or into drainage grooves dug between rows. They will also help in removing excess water during the rainy periods of the season.

Fungal culture diseases

Fusarium, pitiosis, powdery mildew and other diseases caused by fungal spores provoke the appearance in different places sheet plates of light, brown or yellow spots and borders. Fungi are activated during sharp fluctuations in temperature, during periods high humidity and when condensation forms on the leaves. Avoid getting drops of moisture on the tops during watering.

Etching helps prevent the development of diseases planting material in solution blue vitriol(1%) or potassium permanganate (1%) and compliance with crop rotation rules (cucumbers are not grown after all plants of the pumpkin family).

In case of activation of the pathogen, it will be necessary to resort to the treatment of plantings of cucumbers with chemical or biological fungicides, for example, with a solution of whey or milk with the addition of a few drops of iodine tincture, otherwise crop losses cannot be avoided.

Biological preparations using natural enemies of phytopathogens and phytophages against pathogens, for example, Trichodermin, Planriz, Pentafag-S, have proven themselves well for protection against bacterial and fungal diseases.

nutritional deficiency

A lack of potassium, copper, iron or manganese can be manifested by yellowing of cucumber leaves and the appearance of light veins on the plates. Root and foliar top dressing with a solution of micronutrient fertilizers, potassium magnesia or ash infusion help to eliminate the imbalance. At the first sign of trouble, it is recommended to shed the soil on the beds with a slightly pink solution of potassium permanganate.

Pest Invasion

The spread of cucumber aphids, spider mites, whiteflies and other insects that feed on leaf juice in plantings is manifested by yellowing of cucumber tops. Synthetic insecticides or folk remedies help get rid of insects.

In more detail, how to deal with the listed pests using folk remedies, we told in the link.

plant aging

Massive yellowing of the leaves and their coarsening at the end of the season is a normal process, signaling the end of the growing season. In dry summers, this period comes earlier.

To prolong the youth and fruiting time of plants, experienced gardeners foliar treatment is carried out on the tops with a strained infusion of rotten hay (1/2 bucket of raw material is poured to the top with water, insist 72 hours). Multiplicity of the event 3 times with an interval of 5-7 days.

This information will help you avoid problems such as yellowing leaves when growing cucumbers. Carefully observe the condition of the leaves of plants in order to take timely action at the slightest sign of trouble. Excellent harvests of pumpkin culture to you every season!

Every gardener knows that the leaves can be used to judge the health of cucumbers. If they turned yellow, then there is reason to think. So, why do cucumber leaves turn yellow in a greenhouse and open field, further ...

Why cucumber leaves turn yellow - diseases and pests

Consider the main reasons why the leaves of cucumbers turn yellow and dry out.

• Insufficient watering or waterlogging

As a rule, this is the most common reason why cucumbers begin to turn yellow.

Cucumbers need to be watered warm water(+ 24C) 1-2 times a week, after 3 days, in the period before flowering and fruiting.

When cucumbers begin to bear fruit, they need to be watered more often, after 2 days, and in the heat, daily watering is required, wetting the soil deeply.

In cool weather, the number of waterings should be reduced.

• Cushioned landing

If you notice that the old lower leaves on the cucumbers have turned yellow, then this is a direct indicator that the cucumbers are too densely planted and they do not have enough sunlight.

Thin out plantings, tie up and form whips, regularly remove old leaves.

• Changes in night and day temperatures

Remember one thing important rule, cucumbers stop growing if the temperature in the greenhouse becomes + 10 C or lower, and when sub-zero temperature they are dying

Therefore, monitor the temperature and be sure to cover the plantings with covering material if there is a threat of frost.

• Nutrient deficiency

This plate indicates the main symptoms of how a lack of trace elements in cucumbers manifests itself.

• spider mite, whitefly, tobacco thrips

These pests usually live on the inside of the leaf. They cause the leaves to stain, turn yellow and dry out.

To prevent this from happening, you need to ventilate the greenhouse, spray the leaves, and water rationally.

Acaricides and insecticides are used for processing (Caviar M, Aktara)

• Downy mildew or downy mildew

These are numerous pale yellow spots on the leaves that increase in size. Further, the leaves turn brown, dry, covered with a white bloom.

The disease occurs with changes in temperature and high humidity.

Treatment bottom surface leaves with HOM preparations, oxychom, bardos liquid

• powdery mildew

White appears on the upper side of the sheet. This can only occur when overfeeding with nitrogen complex fertilizers.

Spraying with fungicides (Topaz, Fundazol, Skor, Previkur)

• Anthracnose

The disease is characterized by yellow spots on leaves and fruits.

This fungal disease affects both young and mature plants. The ovaries wither, the leaves turn yellow, the roots rot. As a rule, this is due to poor soil in the greenhouse and sudden changes in temperature in it.

Reasons why cucumber leaves get yellow, can be very diverse. Unfortunately, such a problem can affect both plants planted in a greenhouse or greenhouse, and - in open ground.

When is yellowing a normal variant?

If the individual lower leaves of the bush turn yellow, you should not worry. This is considered the norm, as the cucumber bed is often very dense, and sometimes the old leaves do not have enough light. Therefore, the leaf turns yellow and dies, but this does not affect the well-being of the plant itself.

Unsuitable agricultural conditions

Cucumbers are plants that require constant care. They love warmth and moisture, they need nutrients for normal growth. If these conditions are not met, then their leaves turn yellow.

temperature difference

Cucumber crops are hard on frosts, due to which their leaf color may change, and the bushes will stop growing and developing. Such a situation can occur, for example, at the end of May, when the seedlings are already in a greenhouse or under film shelters. If the air temperature drops sharply, the plant may turn yellow and stop growing.

Incorrectly selected watering mode

If yellow spots appeared on the leaves of the plant, then watering was poor. Cucumbers require abundant watering so that moisture saturates all the roots. If there was little water, the plant is forced to have roots near the surface, where they are easily damaged during loosening and weeding.

Excess water is no less harmful than underfilling. It leads to rotting of the roots and death of the bush.

Lack of nutrients in the soil

If a plant lacks nutrients in the soil (such as nitrogen, magnesium, or iron), it may experience yellowing of the leaves. In the future, the unfavorable composition of the soil may also affect the stems of cucumbers.

How to understand which substances are missing?

1. Nitrogen. If this is the problem, then at first the leaves become lighter, and over time they begin to turn yellow. Gradually, the color and lashes of cucumbers change, and the fruits grow ugly.
2. Magnesium. If the leaf of the plant turns yellow around the edges, this indicates a magnesium deficiency.
3. Iron. If the color of the leaf has changed to light purple, and green streaks are visible against this background, this is due to iron deficiency.

Excess ovaries

In addition to the above reasons, there is another one that can explain why cucumber leaves turn yellow in a greenhouse. If we grow cucumbers not in open ground, but in greenhouse conditions, they begin to grow rapidly.

If you planted a hybrid variety, then up to 150 ovaries can form on one cucumber. Often this situation weakens the plant, which is why it changes the color of the leaves to yellow.

Diseases and pests

If the plants are sick or attacked by pests, this is reflected in their leaves. This is especially true for fungal infections.

1. Fusarium. At first, the plant develops well, but during the appearance of the ovaries, the leaves of the cucumbers change their color. Over time, the ovaries dry and die.
2. Powdery mildew. Spots form on the tops, which eventually occupy the entire area of ​​the leaf, if you look closely, you can also notice a white or slightly reddish coating on the leaves. In the future, the affected leaves turn yellow and dry completely.
3. Peronosporosis or downy mildew. Yellow spots are visible on the leaves of the plant, which eventually acquire an oily structure, and then turn brown. On the underside, where spots are visible, plaque appears Brown. From this disease, a cucumber can die in a few days.
4. Root rot. It is she who often affects cucumbers in greenhouses. At first, the weakest plants begin to suffer from rot, but gradually the disease gets to stronger ones.
5. Melon aphid. If you turn the lower leaves of the plant over, you can see a colony of these insects that suck the juices from the cucumber.
6. Spider mite. He settles on the leaves, with inside, and weaves cobwebs. As a result of the defeat, the tops of the plant are covered with light or yellowish spots and gradually die off.

We figured out why the leaves of cucumbers that have already been planted in the ground turn yellow. But sometimes, yellowing affects the plant while still in seedling state.

Why do cucumber seedlings turn yellow?

The causes of yellowing of leaves in seedlings and adult plants are generally similar. If they are detected and eliminated in time, seedlings can be saved.

1. There are few micronutrients in the soil. Because of this, the plants become lethargic, grow poorly. They need nitrogen, potassium, calcium, manganese, sulfur.
2. You either watered the seedlings too often, or you forgot to do it.
3. Plants don't get enough sunlight. Place seedlings on bright window sills. If the weather is cloudy, illuminate it with lamps.

1. The seedlings do not have enough space, as you planted them in tight cassettes. If the roots of the cucumber rest against the walls of the pot, the plant cannot develop normally. Choose large pots for your seedlings and don't plant them too early to prevent them from overgrowing.
2. The cucumbers are frozen. Seedlings are recommended to grow at a temperature of 20 to 25 degrees C °. If the air temperature is below 17 degrees C °, then the plant cannot fully obtain all the nutrients it needs. If you keep seedlings on the balcony, take them indoors at night so they don't freeze.
3. Diseases or pests are to blame. As in the case of adult plants, this can be a spider mite or melon aphid, as well as diseases such as root rot, powdery mildew and fusarium (which we talked about in the previous section).

Why do cucumber ovaries turn yellow?

If the leaves of cucumbers turn yellow, you can intervene in time and save the plant and the future harvest. It is much more offensive when they turn yellow, dry, and then the ovaries and small cucumbers fall off.

What can cause the ovaries to fall off?

1. Lack of lighting. If you plant cucumbers too thickly, upper leaves bushes will be the penetration of sunlight. Remember that modern hybrid varieties often overgrow in greenhouses.
2. Temperature fluctuations. Cucumbers must be protected from overheating and a sharp jump in temperature. If it was very hot during the day and cold at night, the plant may begin to get rid of the ovaries.
3. Lack of nutrition. If cucumbers do not receive the nutrients they need (nitrogen and potassium), this is also reflected in the ovaries: they change color and fall off.
4. There are too many ovaries on the bush. The plant spends a lot of energy on the ovaries, so it does not have enough strength to grow fruits from them - large cucumbers. Excess must be removed before the flowers have blossomed.
5. Not proper watering. If you use ice water for irrigation, then most of the ovaries will fall off. Remember that the water must first be defended in order for it to heat up.
6. The bees did not have time to pollinate the cucumbers. This happens in a rainy summer or at a time when there is a strong heat. The flowers of the plant remain unpollinated, so they die.

How to prevent yellowing of cucumbers?

How to help cucumbers? What to do so that their leaves do not turn yellow? If you properly care for plants, the appearance yellow leaves on cucumbers can be prevented.

1. Cover plants during frost. We cannot influence the weather, but it is not difficult to protect already planted cucumbers from frost. Cover them with bubble wrap or lutrasil. If this does not help, put bottles in the greenhouse, after pouring hot water into them.
2. Don't forget to water. For watering, use for it only warm water. On hot days, water the cucumbers every day. If the weather is moderate - at least 2 times a week.
3. Fertilize your plants. If the soil lacks certain nutrients, use fertilizers. When you do spring or autumn digging, add rotted manure to the soil (2-3 buckets - per square meter). But do not overdo it, too much fertilizer also often leads to the fact that the leaves turn yellow.
4. Remember crop rotation. Cucumbers can be grown in the same place every 4 years. Then fungi and harmful microorganisms will not accumulate in the soil. Also, to protect against diseases, a constant change of varieties is useful.
5. Do not plant cucumbers too densely, this applies to both planting in the greenhouse and in the open field. If these are parthenocarpic hybrids - plant 1 or 2 bushes per square meter, and varieties pollinated by bees - 2-3 pieces per square.
6. Carry out preventive spraying from pests.
7. Make sure that the cucumbers are not overloaded with ovaries. On one cucumber there should be no more than 20-25 ovaries, it is better to remove the rest.
8. Do not forget about regular pinching, which helps to properly form a bush.

If you protect cucumber seedlings and adult plants from diseases and pests, and also arrange for them proper care, then such a problem as yellowing of the tops and ovaries of cucumbers will bypass your beds.

Video: causes of yellowing cucumber leaves and methods of treatment

Yellowing of seedlings in cucumbers- a common phenomenon that almost all gardeners have to deal with.

It happens that the entire leaf turns yellow at once or only its edge, and it happens that yellow spots appear on the leaves or seedlings begin to dry without any obvious reason. In any case, such phenomena are evidence that the plant is under stress and it is urgent to resort to any action to save the seedlings.

This article will tell why yellowness appears on cucumber seedlings and about what to do when the seedlings begin to turn yellow and dry.

Why do cucumber seedlings turn yellow?

The following main reasons for the appearance of yellowness on cucumber seedlings:

• The reason for the yellowing of the leaves of cucumber seedlings may be a lack of light. In this case, yellowness can be observed on the lower leaves of plants, followed by their death. This is due to the fact that the penetration of sunlight to the lower tier can be limited due to the volume of the upper leaf cover. With this phenomenon, it is necessary to remove fading leaves in a timely manner so that the dying leaves do not pull on themselves some of the oxygen and nutrients.
• Next possible cause of yellowing cucumber seedlings- Too much or too little moisture. In moderate weather summer period cucumbers need to be watered abundantly three times a week, and in case of rather hot weather, watering should be done daily. If the roots of cucumbers do not receive the right amount water, they tend to rise, which contributes to the exit of the root system from the ground, followed by their drying. If we talk about an excess of moisture, then in this case the root system begins to rot, which in the end is also manifested by yellowing of the seedlings.
• Influence seedlings, maybe plant infection by fungal diseases, which is manifested by the appearance on the leaves rusty spots with subsequent wilting of seedlings. As a rule, a sharp change in weather can affect the appearance of fungal diseases.
• Appearance harmful insects can also cause yellowing on the plant. Spider mite or whitefly drink juice from cucumber tops and leaves, which as a result leads to the death of the plant. Pests can be overcome only by spraying cucumbers with special chemicals that are sold in specialized gardening stores. But in case there is a need to get an exceptionally clean crop, then it will help self-cooking organic solutions to kill insects.
• The most common cause of yellowing on the leaves is considered a lack of nutrients. It happens that cucumbers are grown in the same areas of the garden for several years. It is important to remember that leads to the impoverishment of the soil. The lack of micro or macro elements can be manifested by yellowing of the edges of the seedlings, followed by their drying. In order to avoid such problems or to eliminate them, timely feeding of the plant will help in compliance with the rules of agricultural technology.
• The manifestation of yellowness may be a signal that the plant has undergone hypothermia. The homeland of cucumbers is the Indian jungle, which has a rather hot and humid climate, so the heat-loving plant suffers greatly at the time of cold snaps or prolonged rains.
• Damage to the roots of cucumber seedlings also leads to the appearance of yellowness. This phenomenon is due to the fact that plant nutrition passes through root system, and in the event of a violation of its normal functioning, the plant begins to die, and this manifests itself first very much through the leaves. This phenomenon can occur when the seedlings were planted in open ground too early, or if the roots close to the surface were mechanically damaged when removing weeds or loosening the soil. Therefore, it is best to replace loosening the soil with its mulching, and pulling out weeds with cutting them to the ground level.
• Foliage yellowing may be due to sunburn, which appears on the plant as pale yellow spots. To avoid this phenomenon, it is necessary to water the plant exclusively under the root, and when greenhouse cultivation make sure that condensation does not collect on the leaves. As a rule, in this case there is no particular reason for excitement, the main thing is to prevent moisture from re-entering cucumber seedlings in bright sunlight in the future.
• In addition to the main listed reasons caused by external irritants or negative factors, one should not forget about the absolutely natural phenomenon that causes yellowing of foliage - physical age of the plant. Thus, seedlings may turn yellow at the end of the season, when the plant is already beginning to die.

As professional gardeners note, in order to prevent the appearance of yellowness on seedlings, it is necessary to follow all the rules of agricultural technology and crop rotation when growing a plant from the moment the cucumbers are planted.

It is worth dwelling on these rules in more detail:

1. The place for planting cucumbers should be changed annually, but they should not be planted after pumpkins or zucchini, as there is a possibility of fungal diseases on plants.
2. It is necessary to adhere to the rules for watering cucumbers - do not overfill them, and prevent excessive drying of the soil. If it is not possible to ensure proper watering, for some reason objective reasons, it is necessary to mulch the bed with grass.
3. In order to avoid the impoverishment of the plant, it is necessary to apply fertilizers in the form of nutrient mixtures or solutions in a timely manner.
4. When seedlings are in the phase of formation of three - four sheets, cucumbers should be sprayed with a prophylactic solution consisting of one liter of milk, twenty drops of iodine, twenty grams laundry soap and ten liters of water. It is worth noting that such a procedure can be carried out regularly, maintaining an interval of ten days from the moment of the last spraying.
5. To prevent fungal diseases, it is necessary to shed the plant with a soda solution in June. One tablespoon of soda is diluted with ten liters of water, and then the liquid is poured under the root of the plant.

After it was possible to determine why the leaves turned yellow, in order to save the crop, it is necessary to take certain measures in a timely manner, which are described below.

Ways to restore cucumber seedlings

The universal method of restoring the normal functioning of the plant is considered spraying seedlings with fermented milk solution, consisting of two liters of kefir or whey, diluted in ten liters of water.

If the leaves began to turn yellow and dry due to the appearance of pests on the plant, it is necessary to prepare an onion solution for spraying.

To do this, you need to boil seven hundred grams of onion peel in ten liters of water, after which the solution is infused for twelve hours, filtered and diluted with water in the ratio of one part of the solution to four parts clean water. The plant is sprayed with the solution, starting from the top smoothly moving down the seedlings. For a better effect, the rest of the mixture can be spilled over the bed.

If yellowness has just begun to appear, then a weak solution of manganese and water can help in this situation.

Sometimes gardeners, once again, examining their beds, notice that cucumber leaves turn yellow on the beds. There are many reasons for this phenomenon. This also includes improper care, unsuitable soil, various diseases and pests ... It is important to notice the disease in time, determine the cause and take measures to eliminate it.

Why do the leaves of cucumber seedlings turn yellow

There are several reasons for the yellowing of leaf plates in cucumber seedlings. To understand how to help culture, it is necessary to determine what negative factors influenced the following changes:

• there is not enough space for the plant;
• the presence of diseases or pests;
• nutrient imbalance.

When planting seeds, keep in mind that cucumber crops require a lot of space for a healthy root system to grow. Peat pots and other containers have limited space, so it is important to have time to transplant seedlings on permanent place. Do this with the advent of a couple of leaves.

The leaves on cucumber seedlings can turn yellow both from a lack of fertilizers and from an excess. In the first case, it is desirable to introduce the missing fertilizers into the soil. With a lack of phosphorus, magnesium or potassium changes pigmentation Bottom part sprout, when iron is in short supply, zinc is the top. With an excess of nitrogen, you should try to save the bush by treating the soil with ash.

Why the leaves of cucumbers turn yellow already in the beds

Often, the tops and leaf plates of cucumbers can change pigmentation to yellow tint and on mature plants. Many agrotechnical or biological factors can contribute to this phenomenon:

• improper care;
• poorly established watering;
• poor quality soil;
• insect damage;
• infectious diseases.

By detecting in time a problem that causes yellowing of leaves in cucumbers and correctly identifying the cause, you can easily save and grow a healthy crop.

Agrotechnical factors

A common cause of yellow spots on cucumber foliage is errors in watering this crop. The plant must be watered abundantly - so that moisture saturates the entire root system. Frequent but sparse watering moistens the soil superficially, forcing the roots to settle closer to the surface. What provokes their damage during weeding or loosening and makes it difficult for nutrients to enter.

Irrigation schedule depends on natural conditions: on hot, dry days, you need to moisten the earth daily, with moderate weather conditions- a couple of times a week with warm settled water. Watering should be done under the root to avoid burns of greenery.

ATTENTION! In cases where the summer is rainy, the roots of cucumbers can rot, which leads not only to a change in the color of the leaves from green to yellow, but even to the death of the entire plant.

The lack of nutrients in the soil negatively affects the development of culture. With a magnesium deficiency, the cucumber leaf turns yellow around the edge. Green streaks on a light purple background indicate a lack of iron. With a lack of nitrogen, the entire whip suffers. Introducing necessary feeding can completely improve the situation.

Another one possible reason why the leaves on cucumbers turn yellow - not chosen for the garden suitable site. According to the culture, it is impossible to grow annually in one place. Pathogenic organisms and fungi accumulate in the soil. greenhouse soil it is desirable to disinfect annually or completely change the earth.

Biological factors

When affected by fungal diseases, yellowed leaves may also appear on cucumbers. The lashes of plants become drooping and do not respond to watering at all. The tops are covered with light or brown spots, which soon increase, capturing the entire area of ​​the plate. Cucumber leaves dry up and die. Such symptoms are manifested in the following diseases:

• pitiosis;
• fusarium;
• powdery mildew.

Leaf plates can also turn yellow when pests attack cucumber beds. They suck the juice from all parts of the vine, resulting in a deterioration in its condition. Such insects include: whitefly, worm-like nematode, aphids and spider mites.

With unreasonably frequent watering or with lingering rains cucumber culture can get sick with bacteriosis. It manifests itself in spots of dark color, which, after the fall of morning dew, become like oily mucus. If timely measures are not taken, the disease can destroy the entire bush.

Preventive actions

The following measures will help prevent the appearance of yellow leaves on cucumbers:

• selection of high-quality seed or seedlings;
• choice suitable place for the formation of beds;
• responsible approach to soil preparation;
• proper care.

Cucumber culture can be planted in one place 1 time in 4 years. So fungi and pathogens will not be able to accumulate in the earth. If this is not possible, the soil must be disinfected. Place the bed in a slightly shaded area during the hot afternoon hours. This will help conserve moisture in the ground and protect the plant from burns that cause yellow pigmentation on the leaves.

Can protect the foliage of cucumbers from premature yellowing and wilting proper preparation soil. If during autumn digging garden, humus was not introduced into the ground, it is worth fertilizing it with mullein in the spring. Top dressing with humus or solution chicken manure should be applied before the appearance of stronger ovaries.

Another one preventive measure- properly adjusted watering. If you stick to it, then you will never see how the edges of the leaf plates of cucumbers begin to turn yellow. The most abundant watering must be provided during the formation of fruits.

Folk methods of struggle

Experienced gardeners know what to do if the leaves on cucumbers turn yellow. And they take appropriate action. Moreover, it is not always necessary to resort to the help of chemicals. Often you can get by with folk remedies.

Capable of garlic infusion. To prepare it you will need:

• 50 gr. chopped garlic;
• 40 gr. laundry soap;
• 1 liter boiled water.

The crushed garlic mass must be poured with water, mixed, tightly closed and placed in a dark place for 24 hours. Before use, the mixture is filtered and diluted with warm soapy water in a ratio of 1:9.

The best remedy for many ailments that cause the leaves on cucumbers to turn yellow is ash solution. To prepare the solution you will need:

• 1 glass of wood ash;
• 10 gr. laundry soap;
• 2 liters hot water.

The ash must be filled with water and defended for 2 days. After, strain and add finely planed soap. The tool is used in two approaches with an interval of 1 week.

The use of industrial preparations

To destroy fungal diseases, you can use the drug "Kvadris". Immediately before use, prepare a solution in the following proportions:

• 8mg per 10 liters of water.

When the leaves turn yellow on cucumber lashes, spraying is carried out in the complete absence or with a slight wind, so as not to provoke the drug to enter neighboring beds. The fruits can be harvested only after 3 days.

Defeat fungi and bacterial diseases capable of 1% Bordeaux mixture. For cooking you will need:

• 2 plastic buckets;
• 100 gr. copper sulphate;
• 100 gr. lime;
• 10 liters of water.

In one bucket, mix blue vitriol with 1 liter of hot water. After complete dissolution, add another 4 liters of liquid. In another bucket 100 gr. lime is quenched with 5 liters cold water. Then in mortar slowly pour in the copper sulfate solution. Cucumbers with yellowed leaves are processed twice with an interval of 2 weeks.

The fungicide HOM can defeat bacteriosis and peronosporosis. For 10 liters of water you will need 40 g of the drug. To prepare a solution, the drug is diluted in a small amount of liquid and mixed. After the amount of funds is brought to required amount by adding the rest of the water.

ATTENTION! Use chemicals to get rid of pests and diseases of cucumbers should be only in exceptional cases. Choose drugs with the least toxicity.

The problem of yellowed greens can be avoided by observing crop rotation and agricultural practices for growing cucumbers. Responsible approach to providing nutrients, control and timely measures to maintain a healthy state of the soil will help to reap a healthy, rich harvest.
