Green soap for spider mites on cucumbers. Spider mite on cucumbers

According to experts in the Russian Federation, there are about 13 types of harmful mites that affect vegetable crops. The most dangerous member of its family is the spider mite. He is capable of inflicting massive damage in a short amount of time.

spider mite

The insect belongs to the category of harmful arthropods. The most famous species found on vegetable crops is Tetranychus urticae (spider mite). Its dimensions reach 0.4 - 0.5 mm in length, it has a greenish or dark brown color.

A favorable climate for pest reproduction is dry and warm air (humidity below 60%, t above 25 degrees). Even after various chemical treatments, the spider mite tends to recover very quickly and significantly increase its colonies.

The insect initially settles on the underside of the leaf, damages it and feeds on cell sap, wraps it in cobwebs. Gradually, the culture begins to turn yellow, and then dies.

The nature of the defeat of cucumbers

You need to sound the alarm if the following changes appear on the cucumber leaves:

• white dots or yellowish spots on the back and at the base of the leaf;
• girdle, thin web;
• drying and falling tops;
• the plant slows down growth.

Pest control methods

The cucumber mite is very dangerous for vegetables, it will take a lot of strength and patience to destroy it, it will not be able to cope with it with one spray.

Treatment with chemicals

It is necessary to take measures against the spider mite when the first signs of damage to the plant are detected. If the leaf has already begun to dry and a web has appeared on it, then the females have laid eggs and soon the pest colonies will increase tens and hundreds of times.

1. 1. Fitoverm- has an effect not only on the spider mite, but also on many other pests. To improve the effect, it is worth combining with pyrethroids.
2. 2. Fufanon, an insectoacaricide with high toxicity to ticks and other pests, is also unsafe for humans.
3. 3. Apollo - acaricide that stops the population. It does not cope with an adult, but it kills eggs and sterilizes the female.
4. 4. Neoron is a drug that perfectly copes with any harmful mites.

Undoubtedly, pesticides give the greatest effect in the fight against harmful insects, but they also have a significant toxic effect on humans. At the same time, the spider mite has learned to develop resistance (adaptability) to these drugs.

This method also has a disadvantage: if the spider mite population has reached a mass infection, the predator will most likely not cope.

Prevention is the key to plant health

A mandatory preventive measure against this pest is to prepare the soil for planting a cucumber crop:

When starting planting, do not place the seed or sprouts too close to each other. If the correct distance is observed, this will quickly neutralize the plant affected by insects.

One of the main rules for the prevention of pests is caring for the beds: planted vegetables must be constantly watered, weeded, removing weeds, and periodically inspect the leaves and stems. If the pest is still seen on the sprouts, immediately remove and destroy the infected plant. This action will help prevent the spread of the mite throughout the future crop.

You can sow dill between the cucumber rows, with its smell it will scare away the tick.

If planting is carried out in protected ground, a mandatory requirement is to carry out a chemical or heat treatment of the greenhouse.

The spider mite is very hardy, resistant to weather conditions and chemical treatments. But do not despair, the spider monster can be defeated. If you take care of cucumbers correctly and in a timely manner, the plant will thank the vegetable grower with a wonderful, plentiful harvest.

The spider mite is one of the most notorious garden pests. It is able to destroy absolutely everything, without exception, cultures, and in just 1-2 weeks it can destroy plants. It is often possible to detect spider mites on cucumbers. Conventional spraying cannot cope with it, as it intertwines the affected area with a network. However, there is absolutely nothing impossible, the main thing is to choose the best way and follow the right advice.

The cucumber mite is a minor arachnid creature. The rate of their growth depends on the air temperature: the warmer, the stronger they breed. During extreme heat or during the cool season, females do not feed. They migrate to protected areas and can move from greenhouse to greenhouse if the buildings are close.

• Spider mites on cucumbers suck the contents of cucumber cells.

• In addition, they infect the culture with infections, for example, gray rot microorganisms.

As a result, the plant loses strength and immunity to other pests and diseases.

Signs of defeat

Signs of damage include:

Fighting methods

What is your preferred method of dealing with spider mites?

Folk wayUse of drugs

Biological ones take into account the attraction of other pests to their own site, which is not always practical.

Chemicals

• Akarin. Method of contact-intestinal influence. Destroys all varieties of plant mites, safe for the environment, completely neutralized in the soil. The period of intensive action is 4-8 hours. Plants are not safe for humans for 3 days from the moment of final spraying.

• Apollo. Acaricide that destroys larvae and eggs of fruit pests. Sterilizes adults. It can be combined with other substances. It is neutral for insects and bees, functions selectively only on mites. Leaves of affected plants are generously moistened with the substance of this drug.

Folk remedies

Before turning to "chemistry", it is possible to try to influence pests with folk recipes. In the initial stages, if the infection of plants is not running, these methods provide excellent results. There are plants that repel cucumber mites. They contain characteristic poisons. Most of all, infusions of them are used for preventive spraying. But it is impossible to exceed the dose, as this can ruin the plants. Here are some recipes:

• Marigold flowers, water. Fill 1/2 bucket of dry marigold flowers with warm water and soak for 2 days. Add 40 g of laundry soap to the filtered infusion. Spray cucumber plantings in the evening.
• Potato tops. Infuse 1.2 kilograms of fresh leaves in a huge dose of warm water for 4 minutes. Generously moisten the affected plants with this substance.

• Tomatoes, water. Pour 4 kg of tomato tops with 10 liters of water and boil for 30 minutes. Add 40 grams of laundry soap to the mixture. Dilute this concentrate in half with water and process the plants.
• Medical alcohol (96%). Wet a piece of cotton wool with it and wipe the leaves of the plant - the tick will be destroyed (recall that it will not take eggs in this way). Ethanol has the ability to instantly evaporate, for this reason, the leaves of the plant should not be damaged at a theoretical level.
• Soap(Economic is more correct, but any other will do). If you have a spider mite, the plant can be treated with ordinary soap:

1. To do this, wipe all the leaves and branches with a soapy sponge. The more foam, the better.
2. We also spray the earth with soapy water, but quite a bit, so as not to get on the roots and not spoil the plant.
3. Unfortunately, many gardeners act significantly and spill the entire earthen ball, and then are amazed that the plant has dried up after a week. Do not repeat extraneous mistakes, there must be a measure in everything! So, after you lather the plant, take your time to wash off the foam. Wait 3-4 minutes - this will be enough.
4. Soap products form a film on the leaves through which gas exchange does not take place, that is, the plant “does not breathe”. For this reason, leaving it in such soapy conditions overnight is dangerous. After the soap is washed off, cover the plant with a bag for a day, without waiting for the water drops to dry. This will be a "double whammy" for those mites that are still alive after the soap. High humidity under the bag will be unbearable for them and they will disappear.

You can also sprinkle the plants with soapy water, instead of rubbing with a sponge. In some cases, this is an exceptionally correct decision, for example, if a large number of plants with small leaves are infected. Wipe each leaf - you are tormented, and it is possible to spray in a matter of minutes. By the way, as an alternative to soap, it is possible to use any dishwashing detergent, for example, the same "Fairy".

• Infusion of garlic. Take 2 cloves of garlic and finely chop them. We put the purchased raw materials in a jar and pour 1 liter of water, cover with a lid. We put the jar in a dark cabinet and insist 5 days. After this time, we spray the plant with the acquired infusion, diluted with water in a ratio of 1: 1.
• Infusion of onion skins. Pour 100 g of onion peel with 5 liters of water and leave for 4-5 days. After the infusion, strain and spray the affected plants.

Prevention

Than, to treat the disease, it is easier to avoid it. With the defeat of a cucumber by a spider mite, everything is the same, and it is necessary to prevent the "disease" with the help of preventive measures.

In order for cucumbers or other plants on the site not to become a victim of this gluttonous and numerous insect, you should:

1. Timely carry out weeding of the place with untreated vegetation.
2. For the winter, be sure to carry out a thorough digging of the site, which helps to eliminate numerous pests in the cold winter.
3. If cucumbers are planned to be grown in protected ground, then thermal or chemical treatment of wooden beams is needed.
4. A very good preventive effect is provided by the attraction of natural enemies of the spider mite to the site.

Phytoseiulus

Phytoseiulus - this mite is able to find and eliminate the spider mite at an early stage of plant damage. Among the folk remedies for preventing the spread of ticks, it is possible to advise the use of ordinary dill on the beds. Plants are planted around the perimeter of the cucumber plot. Such a plant protection system can be used both in open ground and in greenhouse conditions.

If cucumber plants were cultivated with chemicals, then it is not recommended to use the plant that was grown on the site for food.

Beautiful and flowering cucumber plants on your site may appeal not only to you, but also to all kinds of pests that can eliminate a full crop in a matter of hours. For this reason, daily monitoring of the place is needed in order to identify the pest at an early stage of plant damage, and the tips that are described in this article can help to cope with this dangerous enemy.

Since it is very difficult to comply with high requirements for the microclimate in greenhouses, pests and infections sometimes develop in them. The reason for the appearance of pests and the activation of pathogens can be incorrect temperature conditions, inappropriate air humidity, untimely harvested plant residues, excess or deficiency of fertilizers and contaminated soil. In this article, we will tell you where does the spider mite come from on cucumbers in the greenhouse, what means are used to destroy it and what preventive measures will help protect the greenhouse from this pest.

Description of the pest

spider mite - an arachnid arthropod of red, orange, yellow-green or whitish color, usually less than 1 mm in size. These sucking pests settle on the underside of the leaves and feed on the cell sap of the plant. Ticks are incredibly prolific: in one season they can give up to 20 generations. The main danger of these pests is that they are carriers of the cucumber mosaic virus.

As soon as spider mites appear in the greenhouse, they spread very quickly, and as a result of their vital activity, the leaves of the plants are depleted, dry and die, which negatively affects both the development of cucumbers and their fruiting. The most comfortable temperature for these pests with an average indoor humidity of 23-33 ºC, that is, greenhouse conditions are just perfect for spider mites.

Signs of the presence of mites on cucumbers are:

• discolored dots and spots on the leaves;
• barely noticeable web;
• slow growth and development, yellowing and drying of the leaves of the plant.

Prevention of spider mites on cucumbers in a greenhouse

If you don't want to fight ticks on cucumbers every year, take preventive measures:

• at the beginning of each season, disinfect the greenhouse with a sulfur bomb: this way you will save the room not only from ticks, but also from other pests, as well as fungi and viruses;
• after harvesting, remove all plant debris from the greenhouse, and at the beginning of the next season, change the top layer of soil 20 cm thick on the beds;
• alternate beds of cucumbers with beds of tomatoes: on tomatoes, mites do not multiply so quickly;
• plant marigolds between the bushes, the smell of which ticks do not tolerate;
• regularly fight weeds and take them out of the greenhouse: it is on weeds that pests settle first;
• strictly observe the agricultural practices of the culture and try to leave slightly larger gaps between the rows so that the ticks do not spread so quickly;
• maintain high humidity in the greenhouse - 80-85%. For cucumbers, this is a normal level, but ticks with such indicators will be damp;
• regularly inspect the plants so as not to miss the moment when ticks appear: the sooner you find them, the higher the chance to get rid of them quickly;
• if ticks are found, immediately start processing cucumbers with folk remedies: plants are sprayed every two weeks, and if ticks have bred, weekly treatments will be required;
• spider mites can be destroyed with the help of their natural enemies phytoseiulus - predators among ticks, it is enough to spread several leaves with phytoseiulus around a bush affected by mites;
• if folk remedies could not rid the cucumbers in the greenhouse of spider mites, use acaricidal preparations.

Folk methods for the destruction of spider mites, of course, are not as effective as chemical acaricides. The advantage of herbal preparations is their low toxicity to humans and the environment, so in the case when there are few pests, try to do without chemistry. In the fight against spider mites, you can help:

• a solution of 30 ml of ammonia in 10 liters of water: wipe the cucumber leaves and spray the greenhouse with the solution;
• wormwood infusion: pour 800 g of dry wormwood grass into 10 liters of water, leave for 2 days, then boil for half an hour, cool, strain and dilute 1: 1 with water - this composition will help you get rid of many pests in the greenhouse;
• decoction of tomato tops: pour 4 kg of chopped tops into 10 liters of boiling water and simmer for 30 minutes, then strain, add 30 g of grated laundry soap for every 2 liters of decoction and stir well - the decoction is effective against ticks and aphids;
• garlic infusion: insist 150 g of dry leaves and garlic husks in 10 liters of water for a day, strain and immediately process the bushes;
• mustard infusion: pour 200 g of mustard powder into 10 liters of water, leave for half a day and strain;
• infusion of potato tops: pour 1.5 kg of chopped tops for 4-5 hours with a bucket of water, strain and use for spraying.

Treatment of cucumbers from a tick in a greenhouse with chemicals

Since ticks are not insects, but arachnids, not insecticidal, but acaricidal chemicals are used to destroy them, the most effective of which are:

plant pin- an agent for combating ticks and aphids, which is produced in the form of sticks: they are stuck into the soil around plants, during watering they dissolve and release the active substance butoxyraboxime, which affects ticks. The drug is intended for the destruction of pests at an early stage of plant damage, the protection period is 1-1.5 months;

Not only in summer cottages, but also on an industrial scale, a spider mite is often found in a greenhouse on cucumbers. They have very succulent leaves, which provide the pest and its larvae with affordable food in large quantities. This leads to the rapid spread of the enemy and the death of plants, and therefore it is important to be able to recognize ticks at the first symptoms of infection. Learn all about control and prevention measures to protect your crop from the threat.

What does a spider mite look like

The initial sign of the defeat of cucumbers is the formation of light yellow dots on the leaves, spreading from the main vein. Already at this stage, it is worth considering how to treat the affected plants, and pay attention to effective means - acaricides, which help to destroy dangerous insects in all stages.

Sad consequences

Photo of affected plants

In total, there are more than a thousand species of plant mites in nature. They can be called cosmopolitans, since they are distributed throughout our planet. In greenhouses, the common one is most often found. The latter is a type of arachnid, which, similarly to its relatives, secretes a quickly hardening secret that wraps around the plant. The web is not immediately visible, but only with a strong infection.

Mite on cucumber leaves

To determine if there is a spider mite on cucumbers in a greenhouse, you should examine the leaves of the plant (especially the upper ones - the youngest ones) for white spots, as well as for the presence of a spider on the back. With a strong defeat, as a rule, the plants turn completely yellow, dry out and become covered with a continuous cobweb. At the same time, the number of pests increases so much that they become easily distinguishable.

Severe damage to shrubs

Stages of development of the spider mite

The period of formation of mites on cucumbers is one week. During this time, they go through several main stages of development:

1. Eggs are round, yellowish in color. From the moment of laying eggs to hatching, an average of 72 hours pass.
2. The larvae are pinkish in color and have six legs. They are in this stage for 24 hours.
3. Nymphs - have eight legs, the body is painted in a reddish or yellow-green hue. The stage lasts up to 96 hours.
4. adult spiders. The body has a pale yellow to deep red tint. Two dark spots can be seen on the sides of the spider. The average body size is 0.5 millimeters, and therefore it is difficult to see it with the naked eye.

Eggs and adults

Another form are females ready for the wintering stage. This form mostly appears in autumn. They differ in the bright red color of the body. Only females, already fertilized, overwinter in order to lay eggs on young plants in the spring. When the temperature drops, the spider mite in the greenhouse practically does not infect plants, but is grouped in secluded places.

How to deal with a tick on cucumbers in a greenhouse

If a cucumber mite has settled in a greenhouse, it is quite difficult to remove it, not only the struggle is important, but also subsequent regular prevention. The effectiveness of various methods and means depends on the intensity of plant damage. In some cases, the combined use of folk, agrotechnical and chemical methods may be required.

Agrotechnical methods

At the first signs of the appearance of a cucumber mite, it is necessary:

• remove affected leaves or completely plants and take them far outside the greenhouse (burn if possible);
• increase air humidity to 85% (spraying with cool water), which creates uncomfortable conditions for the pest, but does not hinder the growth of cucumbers;
• lower the air temperature (in the heat, mites multiply more actively and faster);
• thin out the foliage and make the distance between plants wider (dense planting contributes to a comfortable life of the spider).

Predatory mite phytoseiulus

The above measures to combat the spider mite can slow down the intensity of its spread on cucumbers in the greenhouse. In rare cases (with a weak lesion), you can completely get rid of spiders. But if time is lost, the risk of losing the harvest is great.

Among amateur gardeners, there is an opinion that it is possible to fight cucumber mites with repellent plants (tomatoes, dill, chrysanthemums, marigolds), which are recommended to be simply planted nearby. But this is misleading, since these cultures are themselves at risk of being affected.

A permanent way to eliminate pests is the settlement of predatory mites (for example, phytoseiulus, amblyseius). Initially, this method was used as a folk one, but today such spiders can be bought in agricultural stores. In the off-season, the fight against ticks in the greenhouse is carried out by the following agrotechnical methods:

• thorough cleaning of the soil from plant residues,
• full deep digging of the soil or replacement of its top layer.

Chemical Methods

If there are many infected plants, agrotechnical methods must be combined with chemical agents. An effective way to get rid of the spider mite in the offseason is to fumigate the greenhouse with sulfur. And for spraying plants, the following processing agents are used:

• "Aktellik" - affects adults. One of the most effective drugs. Destroys the nervous system of the pest, which causes organ failure and complete death. Refers to hazardous substances requiring the use of protective equipment. The effect of the drug in greenhouses lasts up to 12 days.
• "Karbofos" - is an insectoacaricide. The result is achieved by direct contact of the chemical with the pest. It should not be used when flowers or ovaries are formed on cucumbers.
• "Demitan" is an acaricide that retains its protective properties after treatment for up to 40 days. It is a dangerous substance for humans. Can be combined with other types of chemicals to keep spider mites out of the greenhouse.
• "Sunmite" is a contact acaricide that affects ticks at any stage. Used for high damage. Considered a moderately hazardous substance.
• "Akarin" - is a biological insecticide that causes the death of pests on the third day after treatment. Included in the category of moderately dangerous drugs. Does not cause immunity in ticks, and therefore can be reused.
• "Fitoverm" is a biological insectoacaricide. It affects contact and through the digestive system of the pest.

Organophosphate insecticide Actellik

The class of low-hazard substances includes the following drugs:

• "Nissoran" - refers to acaricides, and therefore does not affect adults. On the other hand, nymphs, larvae and eggs (including those laid after processing) die completely, which leads to the complete destruction of the population after 10 days.
• "Bikol" is a broad-spectrum biological product. In closed ground provides up to 97% of the death of spider mites on cucumbers.

Spraying cucumbers

Folk remedies

In the experience of gardeners, there are many available methods to help fight spider mites on cucumbers in a greenhouse using improvised means. The effectiveness of such methods is significantly lower, but the safety for humans and plants is much higher. The most commonly used method is spraying with various solutions or infusions of herbs and alkali.

Onion infusions (garlic, horseradish root, tobacco) require regular use, act as a repellant from ticks. For cooking you need:

• clean and grind 200 grams of raw materials;
• pour the resulting slurry with 1 liter of water, temperature 90-100 ° C;
• insist 5 hours in an opaque closed container;
• strain and dilute in equal proportion with water before spraying.

Sulfur-tar soap

Soap solution is the most popular way to get rid of a dangerous spider mite in a greenhouse. It can be prepared from any type of soap, but it is better to take household (70-72%) or sulfur-tar soap, since they do not contain dyes and fragrances. To prepare, you will need to dilute the soap with water in the proportion of 100 grams of soap (about half a piece) per 10 liters of water. Requires regular application every 20 days.

Herbal infusions (dandelion, chamomile, yarrow, hogweed, creeping mustard) help prevent the spread of mites in the greenhouse and on plants. To prepare the infusion you need:

• 100 grams of dry raw materials, gently mixing, pour 1 liter of water, temperature 70 ° C;
• 12 hours to insist in an opaque container with a lid;
• before processing, strain and dilute with cold water in equal proportions.

Drops from fleas "Neostomozan"

Shampoos and flea drops (Neostomozan, Frontline, Bars spray) are used to kill ticks in animals. Their use for plants in greenhouses is an initiative of amateur gardeners. Drops are diluted in proportion: 1 ampoule per 400 milliliters of pure water at about room temperature. Re-treatment can be carried out after 7 days. Most of these drugs are addictive to the insect, and their effectiveness is unstable.

Pest prevention

Competent protection of cucumbers from spider mites in a greenhouse includes comprehensive prevention. It is divided into three stages:

1. Preparatory (spring) is performed before the start of the season.
2. The current one is held continuously throughout the season.
3. The final (autumn) is carried out before wintering.

Spring processing of the greenhouse consists in cleaning the premises after wintering and sterilizing the soil. To do this, do the following:

wash the greenhouse structure, especially the nooks and the upper area with soapy water with the addition of chlorine;

• dig the soil to a depth of 30 centimeters;
• treat the soil with steam (boiling water), and then tightly cover the soil with a film for 72 hours to create high humidity, which is detrimental to this pest;
• fumigate with sulfur checkers;
• evenly spill the soil with a 1% solution of manganese.

Fumigation of the greenhouse with sulfur

Current prevention should take into account what the spider mite is afraid of. This includes the following measures:

• Maintain high humidity in the greenhouse. This can be done by installing a large open container of water indoors or by spraying regularly.
• Planting plants at a sufficiently remote distance and alternating cucumbers with crops that are not susceptible to infection (for example, garlic).
• Regular inspection of plants for damage.
• Thinning and removal of part of the leaves on shrubs.
• Mulching the soil to maintain moisture.
• Spraying plants and soil with onion infusion or a solution of water with sulfur-tar soap once a month.

Mulching cucumbers in a greenhouse

Autumn prevention is as follows:

• Complete cleaning of plant residues and temporary auxiliary structures (garters, trellises).
• Digging the soil with the addition of phosphate fertilizers or lime, which kill the tick.

You can treat the greenhouse from spider mites at any time of the year with solutions:

• colloidal sulfur - dilute 100 grams of the substance in 10 liters of water;
• 20% alcohol solution (alcohol-containing glass cleaners).

Processing consists in washing all parts that can be shelters for an insect. Care should be taken when washing metal parts, especially if they are not painted.

In addition to cucumbers, the spider mite is able to feed on almost all crops. As gardeners and flower growers note from their personal experience, initially the pest always chooses the most delicious crop for it, and the rest may not be touched. That is why the methods of struggle are so diverse and show different results of effectiveness and feedback.

A few more tips on how to increase the effectiveness of the fight:

• The means used should be alternated, since ticks are able to develop strong immunity, especially to chemical preparations.
• It is necessary to get rid of ticks not only in the greenhouse, but also in the area around it, because it is from there that the pest gets inside. There should be a small sanitary zone around the greenhouse without landings.

If the cucumbers in the greenhouse have been completely destroyed, it is advisable to plant other, less susceptible plants the following year.

Video: Fight for the harvest

Spider mites can be a real disaster for the entire crop, and therefore the proposed preventive measures and tips for disinfecting infected greenhouses should not be ignored. Remember that timely detection and competent implementation of protective measures will allow you to quickly get rid of the problem and keep cucumbers and other plants in the greenhouse.

What are the reasons for the appearance of spider mites on cucumbers? The pest appears and actively reproduces only in favorable conditions for it - high temperature and dry air. Ticks hibernate in fallen leaves, topsoil, manure and greenhouses (especially in the corners).

The most unpleasant thing is to protect the crop from the appearance of a pest impossible- it can get on seedlings even with a gust of wind.

The only way out- Carrying out conventional agrotechnical measures in order to prevent the appearance of spider mites.

How to get rid of spider mites on cucumbers in a summer cottage or garden?

Take pest control measures immediately after harvest: All plant parts must be removed and destroyed.

Fighting spider mites on cucumbers also includes:

1. Before sowing, the land must be dig up, because most of the pests hibernate in the upper soil layer.
2. Spider mite hibernating outdoors develops first on weeds so they need to be removed systematically.
3. During cultivation it is necessary scrutinize plants and, if affected leaves are found, they must be removed and buried or burned.
4. Planting cucumbers should alternate with cabbage or tomatoes.
5. If a spider mite is found, the lesion must be treated biological preparations.

How to get rid of spider mites in a greenhouse on cucumbers? Biggest risk plants in greenhouses are susceptible to the occurrence of spider mites.

Here for breeding pests all conditions are created- high temperature (30 degrees and above) and relatively low humidity.

Spider mite on cucumbers in a greenhouse - control measures: The pest does not tolerate humidity above 60%, so increasing its level in the greenhouse to 80-85% is the best method to prevent the development of pests.

Cobwebs on cucumbers in a greenhouse: how to deal with it? When growing cucumbers in a greenhouse, the main methods of dealing with spider mites should be added:

1. Disinfection(fumigation) of the greenhouse structure in the fall after harvesting and in the spring before sowing with complete tightness.
2. Removal after harvest top layer soil.
3. Burning trellises with a gas burner.
4. Fertilizer phosphorus mixtures.

Means for processing cucumbers

How to process cucumbers for spider mites? Which one to use on cucumbers?

The main method of pest control on the site is spraying with insecticides, but in the case of a spider mite, this method will bring little benefit.

The destruction of the spider mite is guaranteed by means such as insecticides and acaricides, but today there are no systems safe for humans that allow the use of these drugs on the site. Most use enteric-contact drugs, which give fairly good results.

Processing cucumbers with intestinal-contact agents should be carried out more than once. The higher ambient temperature- the shorter the interval must be maintained between treatments.

Of the preparations against spider mites on cucumbers, it is worth highlighting Phytoferm.

Spraying should be done in the evening when there is no sun, so that the chemicals do not have time to evaporate and destroy the spider mite.

The safest pest control is phytosailus mite.

The predator is placed next to the affected foci to destroy the eggs of the spider mite, but for the best result, you need to populate the mite every 3 weeks.

Folk remedies

The most popular with spider mites include:

1. Spraying plants soapy water.
2. Landing flowering plants.
3. Settlement of the site Entomophora adjarian mushroom.

Planted dill next to cucumbers will help in pest control. Its flowering attracts ladybugs, which will eliminate the development of aphids and spider mites.

Diseases of cucumbers caused by spider mites

For humans, this pest does not represent no danger, but for cucumbers, a spider mite is special enemy. It not only sucks all the juices from the leaf, disrupting photosynthesis, but also makes the plant vulnerable to a number of infections.

The infected culture gradually begins to dry out, which eventually leads it to death. Spider mites can cause gray mold spore, which affects the entire ground part of the plant. Not only shoots, leaves and flower stalks are under threat, but also fruits.

How to save? Treatment Methods

How to remove spider mites from cucumbers? The affected parts of the plant must be delete, for a few days stop watering to feed the plant nitrogen fertilizers and sprinkle ash spots.

If the disease continues to develop, then it is necessary to take drastic measures- dig up and burn diseased plants, treat healthy ones with special solutions.

The fight against spider mites is the case when an important role is played by prevention. With all agrotechnical measures and careful attention to the cultivated crop, the risk of infection with a spider mite is minimized. And this, in turn, gives a great chance to get big harvest without loss.
