Leaf miners - methods of protection. Common pests of cucumbers: control and prevention measures

Varieties

Mining flies are distinguished by a rather high food specialization, that is, larvae different types feed on certain tissues specific types plants. In most species of mining flies, the larvae eat leaves, but there are species whose larvae feed on fruits, roots, inflorescences, or bulbs. For example, the larvae damage garlic and onion bulbs, which become soft and rot.

Beet

Beet-mining flies cause great harm. Their larvae feed on the leaves of beets, spinach, and other nightshade species. In addition, they can eat wild haze and nightshade. Adults reach 6-8 mm in length. The flies lay their eggs on the underside of the leaf. Several eggs are laid at a time; in her life, one female can lay up to 100 eggs. After four or five days, fly larvae emerge from the eggs, which make moves in the leaf (in other words, mine them). On the surface of the leaf, these mines are visible as dirty yellow swellings. Having settled on young beet plants, the larvae of mining flies often lead to the death of seedlings. At later stages of development, infection with mining flies leads to a decrease in the mass of root crops. At favorable conditions three generations of beet flies can change over the summer. Flies pupate in the ground, and in the ground they winter in the form of pupae (fly pupae are also called false cocoons).

Nightshade

The so-called nightshade miners are tiny flies only 2-2.5 mm long. These insects damage cucumbers, tomatoes, cabbage, lettuce, parsley, celery and gourds. Females of the first generation lay their eggs in cotyledons or young leaves. The larvae that appeared in early spring sometimes cause death of young plants. When flies lay their eggs on leaves, this is noticeable by yellow footprints punctures.

Hatching larvae form clearly visible passages, or mines, in the leaves. Inside the mines, a dark trail of larval excrement can be seen. About three weeks after birth, the larva gnaws its way out, falls to the ground, burrows into the soil and forms a chrysalis there, from which an adult fly emerges a few days later. Breeding in in large numbers, miners retard the growth of plants, and the affected leaves dry up and fall off. But even a small number of miners reduces the productivity of crops.

Ways to fight

Since the pupae of mining flies hibernate in the soil, they dig deep to fight them. ground, due to which the pupae go deeper into the ground and die.

Various insecticides are also used. You can use seed treatment before sowing. For example, in the fight against the beet miner, the treatment of beet seeds with the drug "Taboo" is effective. It makes sense to use the preparations of the group only for soil application.

AT open field Cucumbers infect such unpleasant pests as aphids, sprout and mining flies, cucumber bugs, slugs, and a bear. Often correct agricultural technology, preventive measures taken and spraying with folk safe means helps to cope with pests and prevent their mass distribution. Resort to the use of pesticides only as a last resort with a strong dominance of the pest.

The fight against aphids on cucumbers in the open field

Cucumbers are most often affected by black or green melon aphids. It is also found in greenhouses, brought there with planting material, through open windows, and spread by ants.

• Aphids settle on plants in colonies, completely sticking around tender young shoots and sucking the juice out of them.
• Contaminates leaves with sticky secretions, on which it then settles sooty fungus that interferes with the process of photosynthesis.
• In addition, aphids are often carriers of the cucumber and tobacco mosaic virus.

1. Aphids can initially be detected by the characteristic white skins under the plants left after they molt.
2. The abundance of ants should alert: they instantly spread aphids around the greenhouse.
3. When aphids feed, the leaves of the cucumber shrivel, the tops of the shoots are bent, covered with excrement, black bloom, the plant dries up.

• Destruction plant residues, cruciferous weeds (shepherd's purse, wild radish, colza, etc.)
• Regular inspection of plants.
• The introduction of phosphorus-potassium fertilizers, due to which the plants become coarse and unsuitable for aphids.

Aphids in the garden are a fairly frequent uninvited guest, so they have long learned to deal with it with the help of improvised means without the use of "chemistry".

Infusions and decoctions from aphids

For example, in the initial stages of aphids, spraying with infusions and decoctions of insecticidal plants is useful:

• marigolds,
• dandelion,
• yarrow,
• tobacco,
• tops of tomatoes and potatoes,
• infusion of ash.

Aphid soap

An obligatory component of all folk remedies is soap. Without it, the solution will simply drain off the sheet.

• Can be used green soap for plants or grate the usual household.
• It will improve the adhesion of the product and enhance its effect.
• In addition, soap clogs the aphid's respiratory openings, and it dies.
• When combining herbal decoctions with soap, the processing efficiency increases.

How to treat infusion with soap

1. To 10 liters of infusion or decoction of any insecticidal plants, add 100 g of soap,
2. treat plants, especially from the underside of the leaf,
3. after 5-7 days, the treatment must be repeated.

Ammonia from aphids

A solution of ammonia helps well against aphids:

1. 2 tbsp. l. on a bucket of water with the addition of 100 g of soap.
2. For aphids, this is a lethal mixture, and for plants, it is also an additional nitrogen supplement.
3. After 7-10 days, the treatment also needs to be repeated.

Aphids have numerous natural enemies - insects and birds:

• hoverflies,
• sand wasps,
• ground beetles,
• lacewings,
• and especially ladybugs and their larvae.

Ladybugs from aphids

Who doesn't know these colorful spotted beetles, favorites of the kids? And the offspring of ladybugs - larvae, eggs, pupae - few people are familiar with. Moreover, they are mistaken for garden pests and destroyed just like that "just in case."

You need to know all the stages of development of a ladybug in person so as not to accidentally start a fight with them, because one larva eats up to 100 pieces of aphids and their eggs per day! Often clutches of yellow oblong ladybug eggs can be seen just on the underside of leaves affected by aphids.

In addition, you can attract this useful beetle to the site by planting dill, yarrow, tansy, and cornflower.
If there are ladybugs on the site, you don’t have to worry about aphids, they can provide natural protection for crops.

If there is no way to cope with aphids folk remedies, you can use chemical ones, it is not difficult to find them in stores now.

1. In the fight against aphids on cucumbers, the following are recommended: Fitoverm and Biokill biological products based on compounds produced by natural microorganisms.
2. Biopreparations for protection vegetable crops always preferable chemicals, because do not accumulate in the crop, non-toxic to humans.
3. However, when using them, the same safety precautions should be observed as when working with chemical insecticides, because they are dangerous to bees and others beneficial insects.
4. Preparations based on the systemic substance imidacloprid have become popular means in the fight against aphids, for example: preparations for aphids Tanrek, Biotlin, Antitlya and whitefly (Imidor). They should be used no more than once per season.
5. If re-treatment is necessary, an insecticide from the class of biological products should be used, for example, the same Fitoverm.

Fight against sprout fly on cucumbers in the open field

The sprout fly is a polyphage that damages many types of crops. Damage is caused only by fly larvae at the stage of seed germination - seedlings. This pest matters only where crops are sown, and not planted with seedlings.

• shoots are sparse,
• on the first cotyledon leaves there are deep furrows,
• seedlings rot.

Measures to combat the fly are mainly preventive in nature.

1. , deep embedment of organic fertilizers.
2. Liming acidic soils, which creates unfavorable conditions for the development of larvae.
3. Planting cucumber seedlings
4. Sowing seeds pre-soaked in a solution of one of the growth stimulants, for example, Epin or Biostim Start to increase germination energy.
5. Seed treatment with one of the approved insecticides.

The fight against the miner fly on cucumbers in the open field

The mining fly is capable of damaging many crops - vegetable, ornamental, berry, fruit. It also harms in the greenhouse, with a large number it can populate the leaves of all greenhouse plants. The adult itself - a small fly, is difficult to notice. Most often, the pest is detected by the nature of the damage already inflicted.

• light winding stripes appear on the leaves - the moves of the miner larvae.

The fight against this pest is complicated by the fact that the main harmful phase of the insect - the larva - develops inside the leaf. Therefore, insecticides with contact-intestinal action will be useless. Preventive measures will help to prevent severe infection.

1. deep autumn digging soil
2. Destruction of affected plant residues
3. Use of colored glue traps for adult fly trapping and monitoring
4. Regular inspection of plants for the first signs of damage
5. In case of severe damage, mechanical removal of leaves followed by burning
6. Treatment of healthy tops with one of the permitted insecticides, for example, Fitoverm or Fufanon. When using chemicals, it is necessary to take into account the waiting time from processing to harvest.

Fighting cucumber bug on cucumbers in the open field

This is a small black insect about 3 mm long, its legs and antennae are light, its back pair of legs is jumping, so it moves easily.

1. Adult bugs pierce the leaves of cucumbers, sucking the juice out of them, they especially like to feed on the leaves of seedlings.
2. With a high number of insects, damage to the leaves can be significant, the leaves dry up.

1. Removal from the territory of all plant residues where the bug can overwinter, or embedding them deep into the soil
2. Deep autumn digging of the soil
3. Watering seedlings under the root solution systemic insecticide based on thiamethoxam, such as Aktara. Being absorbed by the root system, the insecticide penetrates into all parts of the plant, making its juice poisonous for the pest to feed on.

Fight against slugs on cucumbers in the open field

The well-known polyphagous pest of the garden, is predominantly nocturnal, during the day it hides under shelters - under stones, lumps of soil, under leaves, in heaps of mowed and rotting grass. Feels very at ease in wet shady areas with dense and abundant grassy vegetation, in beds overgrown with weeds.

1. Having gnawing oral apparatus, slugs roughly eat leaves, sometimes leaving only veins from them.
2. With uncontrolled numbers, they can completely destroy the planted seedlings.
3. They love to feast on juicy fruits, especially those that lie on the ground.

To prevent slugs from breeding too much on the site, organize

1. withdrawal excess moisture from the site
2. regular mowing of grass and weeding beds,
3. remove weeds and cut grass away from the ridges,
4. mulch the soil around the plants with loose material that has sharp edges and a rough surface - chopped straw, sawdust, pine bark or crushed eggshells. It will be inconvenient for slugs to crawl along such a surface to fodder plants.

• It is also useful to sprinkle the soil around the perimeter of the plantings with ash, crushed superphosphate or lime, these products burn the delicate leg of the slugs, they secrete a lot of mucus, and then die.
• Set traps for slugs, where they will hide during the day - spread planks, rags, large cabbage leaves between rows of plants, just lift them up during the day and manually collect pests
• Dig open containers with beer or fermented jam into the beds, where slugs will crawl to the smell. The edge of the container should be level with the soil.

• Attract animals to your site - hedgehogs, toads, lizards, who are happy to feast on slippery pests.

1. Of the chemicals against slugs, metaldehyde-based molluscicides are effective - Thunderstorm, Slug Eater, etc. They are produced in the form of granules.
2. Moreover, more modern drugs from this series - Thunderstorm-3, StopUlit, Predator act more efficiently and have less danger to environment. They act as a bait and are not afraid of getting wet in the water. Mollusks quickly find the granules, swallow them and die.
3. Enough to scatter a small amount of pellets around plants to protect crops from voracious slugs and snails.

Fighting Medvedka on cucumbers in the open field

A very dangerous underground pest of all horticultural crops. This is large insect has a brown body from 5 cm in length, shortened elytra and a front pair of strong spade-shaped legs, with the help of which it quickly moves underground. Medvedka prefers loose, humus-rich soils.

• The base of the stem of the plants is bitten, the plant quickly withers.
• Medvedka's passages underground are easy to detect - they are winding and usually slightly raised above the ground; after watering or rain, the soil in these places dries out faster.

• The beds where the bear lives should be dug deep in late autumn before frosts, without breaking lumps. This will lead to the freezing of most of the living individuals.
• Set up traps for the bear: in the fall, dig trenches 50 cm deep and fill them with straw manure. With the onset of a cold snap, the bears will gather in a trench for the winter. As soon as the first frost hits, the manure from the trenches must be scattered, the pests will die from hypothermia.

1. In summer, in the places of passages, the bears set up traps from cans of kvass, beer, honey or sweet water. The edges of the cans should be at the level of the bottom of the underground passage. Medvedka, attracted by a pleasant smell, falls into a container with liquid, from where she can no longer get out.
2. Prepare a treat for the pest from crushed eggshell sprinkled with fragrant sunflower oil. This mixture is laid in the holes during planting and in the grooves when sowing crops. Medvedka eats the shell and dies.
3. You can scare away the bear from landings by landing in different places plot and in the aisles of plants flowers marigolds, calendula and chrysanthemum.
4. This pest also avoids needles and coniferous odors. Branches of fir, spruce or pine can be laid out between plants. Also, this property of the bear can be used to lure it to the surface from your home: prepare a solution of coniferous extract for baths or make a decoction of the needles yourself, pour it into the holes of the bear at 0.5-1 l, wait until it crawls out to the surface and destroy .

Ready preparations for laying out in holes: Thunder, Medvetoks, Grizzly, Phenaksin Plus.

• When using poisoned baits in the beds where vegetables grow, keep in mind that they are toxic not only for the bear, but also for humans, carefully read the instructions and do not exceed the specified application rate.

What are the pests of cucumbers and how to get rid of them simple and accessible ways. It seems that pest control is endless. Russia is a country where, during the period of planting and growing cucumbers, the climate is hot and arid. He is loved by various pests that actively reproduce and show their activity at high temperatures.

Owners of suburban areas spend a lot of time and effort to care for cucumbers. This process is not easy, but it cannot be avoided if the desire to get a healthy harvest is at stake.

This article will focus on methods of control and preventive measures that are carried out in greenhouse conditions, and in open ground conditions, when growing cucumbers.

Melon aphid on cucumbers - how to deal with aphids on cucumbers

• Description of the cucumber pest

The aphid is considered the most formidable pest, since it first eats the flowers, and then the whole plant as a whole, including the shoots. Since the vital activity of aphids occurs on the plant, cucumbers die.

The activity of this insect comes in the middle of summer. It reproduces at a fast pace. After a few days, the reverse side of the leaf facing the ground is exposed to infection. Flowers and ovaries are also infected.

• How to liquidate

It is important to ensure that there is no grass on the site. After harvesting, it is necessary to remove all the remains of plants completely, leaving nothing, and then burn them. This is due to the fact that aphids can migrate from grass to cucumbers.

In the case when the insect was noticed, prepare a mixture:

1. Fill the bucket with 10 liters of water (the water should have a temperature of about 60 degrees).
2. Capsicum is taken - 30 g. It must be finely chopped. If this pepper is not available, replace it with dry ground red pepper in the amount of 10 g.
3. Take tobacco dust in the amount of 200 g.
4. The components are mixed in a bucket of water.
5. The solution is infused for 1 day.
6. Then it is stirred.
7. Filter.
8. It is necessary to add 4 teaspoons of burnt wood ash to the mixture and liquid soap.

During the treatment of plants with this solution, 2 liters are taken for each square meter cultivated area.

Based on these calculations, it turns out that this bucket is only enough for 5 square meters of land. If the area planted with cucumbers is larger, then more solution should be taken. Repeat this procedure after 7 days.

No less effective will be the use of such a solution:

1. Take a 10 liter bucket of hot water.
2. Add 1 cup of burnt wood ash there.
3. Also add 4 teaspoons of liquid soap
4. Insist 24 hours.
5. Spray, as in the first option.

The weather during this procedure should be calm, without wind. The best time to do this is in the evening.

To destroy aphids, apply at least effective remedy- a solution of karbofos. In a 10 liter bucket, with warm water, diluted 1 or 2 tbsp. this drug. If the solution has an increased concentration, they are treated with tracks and films in greenhouses. When the concentration is weak - directly cucumbers. The processing process is best done in the 2nd half of the day, when the sun is not so intensely scorching.

When procedures related to spraying are carried out, after they are completed, there should be no open windows, transoms, or doors. You can fight aphids with the help of insecticidal infusions.

For this you can use: henbane, garlic, dope, onion, etc. All the solutions below are made in 10 liters of water:

• Henbane (leaves and roots) are needed in the amount of 1.000 g dry, or 500 g fresh. Insist for 15 hours.
• Dry mustard in the amount of 1.000 g insist 24 hours.
• Fresh dandelion leaves - 250 g (or 330 g of finely chopped roots of this plant) insist for 2 hours.
• Add 0.5 tbsp. pepper, mustard.
• Potato tops - 1.000 g, red pepper (ground) - 10 g. These components are insisted for 4 hours, and are urgently applied.
• Onion (1 cup) finely chopped, or passed through a meat grinder. Add 2 tsp. alkalis. Insist for 3 hours. Filter.

Important: before you start using these infusions, add 2 or 4 tsp to them. liquid soap.

Spider mite on cucumbers in the greenhouse and open field

• What are the characteristics of an insect?

If cucumbers have been infected spider mite, the following signs may indicate this:

- appearance of dots light shades(if the lesion is serious, these will already be spots) on reverse side sheet;
- a thin cobweb appeared on the plant;
- growth has become slower;
The leaves have started to turn yellow.

• Methods and actions for the destruction of the pest

What should the owner of the garden or plot do in order to eliminate the spider mite?
Activities that bring good result:

It is necessary before planting seeds, be sure to dig up the ground. This is important because most harmful insects waits out the winter in the upper layers of the soil.

The spider mite first shows its activity while on the weeds. So that he does not get over to cucumbers, they must be cleaned regularly.

It is advisable to inspect plants as often as possible. In the case when the affected leaves are found, they are removed and burned.

We need to change landing sites. You can, for example, next year, plant cabbage or tomatoes in place of cucumbers. As soon as the spider mite has been detected, the sites of infection are treated with biological preparations.

• How to destroy a spider mite in a greenhouse

Those plants that grow in greenhouses are more at risk than others of becoming infected with a spider mite. It is in the greenhouse that the most beneficial conditions for the life of this harmful insect: temperature from 30 degrees, not very high rate humidity.

Methods for the destruction of spider mites on cucumbers in greenhouse conditions:

• If you create a humidity level of more than 60%, the pest will obviously not like it. Keeping the humidity level around 85% in the greenhouse is a good preventive measure to prevent insect activity. If a web appeared on cucumbers, what should I do?
• When cucumbers are grown in a greenhouse, it makes sense to include in the main actions aimed at combating spider mites such as
• Carrying out fumigation of the entire greenhouse in autumn period as soon as the entire crop has been harvested, as well as in the spring before sowing. It is necessary to ensure complete tightness.
• As soon as the crop is harvested, it is necessary to remove upper layer soil.
• Via gas burner, it is necessary to cut the trellis.
• Fertilize the soil with mixtures containing phosphorus.

Insectoacaricides, as well as acaricides, are those drugs with which they destroy the spider mite. Today there are no systems that protect against these means so that they do not negatively affect a person. That is why it is dangerously unsafe to use such remedies.

Gardeners noticed that excellent results after application showed the means of intestinal contact action. Cucumbers are processed with them several times. Everything depends on the temperature. The higher its value, the more often it is necessary to process plants.

by the most effective drugs aimed at the destruction of the spider mite, emit:

• Spark - Bio.
• Phytoferm.
• Karbofos.
• Bitoxibacillin.

Note to summer residents: it is advisable to carry out work related to the processing of cucumbers with preparations in the evening so that the sun does not burn. Then the chemicals will not have time to evaporate, and eliminate the harmful insect.

If you don't feel like messing around with chemicals, there's a harmless way to save your cucumbers. With the help of the phytosailus mite, you can get rid of the spider mite. You need to take a predator, place it nearby near the infected places. The phytosailus mite will destroy the eggs of the pest. To attain maximum effect, colonize the tick every 21 days.

Summer residents and gardeners consider the following to be quite popular folk methods of dealing with spider mites:

1. It is necessary to spray the cucumbers with a solution of soap;
2. It is necessary to plant flowering plants;
3. Planted on the site mushroom entomophthora Adjarian.

Greenhouse whitefly: signs and pest control measures

• Signs by which the whitefly is recognized

If suddenly the owner of the greenhouse noticed a tiny white midge, it could be a whitefly. It also comes in yellow or gray color. It goes through the following stages of development: larva - nymph - adult - imago.

Throughout this period, she needs the juice of plants for her life. To get it, the insect makes punctures in a juicy young leaf.

An adult insect in length reaches no more than one and a half millimeters. The difficulty lies in the intensive reproduction of the whitefly. One individual lays more than 100 eggs. After a week or two, a huge number of children of a harmful insect are born.

A greenhouse is a place that is 100% suitable for whitefly activity. The air is warm here, the humidity just the way she likes it.

What else is needed in order to multiply rapidly? If in a greenhouse heat air, then the larva of a small pest will very quickly become an adult. She, in turn, will be able to fly and lay many eggs on the leaves of cucumbers.

The maturation process usually takes up to 25 days. Adult insects can live from 2 weeks to 1 month. As soon as the whitefly is born, and until death, it will try to harm the plants in the greenhouse, at whatever stage of development it would not be.

• How to deal with whitefly in a greenhouse

If carried out preventive actions in a greenhouse with cucumber plantings, this is much more effective than trying to get rid of the whitefly later, using force and means. The owners of greenhouses should not forget about the ventilation of the greenhouse.

On a note!

Drafts are good, because a small pest cannot stand them. The leaves of cucumber bushes should be regularly examined: whether flies or larvae have appeared on the front or back of the leaf. As soon as there are suspicions that the whitefly has become an inhabitant of the greenhouse, you should immediately start fighting it!

There are certain ways to destroy the white pest. To choose a tool, you need to look and decide on the number of whiteflies.

If plants are infected only on initial stage, it is worth using insecticides with an immobilizing effect. For example, it can be "Aktelik", "Aktara", "Vermitex", "Confidor", etc.

If the plants are treated with these means, the insects are paralyzed. They will not be able to move, and therefore, eat, which will lead them to death within 2 days.

The drug sprayed on the plants lasts approximately 20 days. The larva will still continue its development, since it needs 25 days for this. The effect of the action of the remedy will pass until new adult insects grow.

In the case when the whitefly has already laid eggs, they are suitable for the use of a means for another purpose. These are: "Admiral", "Mospilan", "Match", and others. The main thing is that they eliminate the larvae.

Often, it happens that the means of groups 1 and 2 are used together to control whitefly eggs and adult pests. Be that as it may, it will be necessary to repeat the treatment with plant preparations in 5 days.

It is advisable to change pairs of drugs without repeating 2 times. If the whitefly is darkness, it is worth repeating the procedure 3 times. You will have to show maximum patience, only then the result can please.

Verticillin is a drug that was created from an entomopathogenic fungus. The fungus, if it grows into the body of the whitefly, will kill it with its poisonous substances.

• What biological methods are used to kill the whitefly

This plant is native to Africa. Attracting a whitefly to her, she will eat it, as white pest stick to its leaves.

• macrolofus;
• encarsia;
• trichaporus.

They are used both for preventive purposes and in order to reduce the number of white pests. The first species harms the whitefly in this way: they lay their eggs in the whitefly larvae, killing them in this way. The second species immediately eats the whitefly in its various stages of development.

Forget about pressure problems forever!

Most modern drugs for hypertension do not cure, but only temporarily reduce high pressure. This is already not bad, but patients are forced to take drugs for the rest of their lives, exposing their health to stress and danger. To remedy the situation, a drug was developed that treats the disease, not the symptoms.

• Folk methods treatment of cucumbers from pest damage

Take 7 dandelions, separate leaves and roots from them, cut them, pour them with 1 liter of boiling water. Sprinkle infusion on cucumbers after 1.5 months.

If only the first stage of whitefly damage, garlic infusion will help: 100 g of garlic cloves are peeled, rubbed on a grater, passed through a garlic press, pour 0.5 liters of boiling water. Insist for 4 days. Spray on plants, based on the ratio: 5 grams of the product per 1 liter of water.

An important point: in order for the mixture for spraying cucumbers to keep well on the leaves, it is worth pouring a little liquid soap or shampoo into it. You can also use the adhesive - a special tool.

If a small number of these smallest pests are observed in the greenhouse, it is advisable to use adhesive tapes and traps. They are sold in markets and shops.

You can make them yourself. Near the roots of plants, a mixture of wood ash and shag is scattered, and mosquito repellent tablets are lit.

Germ fly: what harm does it cause and how to get rid of it

• Description

The sprout fly differs in that its larvae harm the plants. The result of their activity is that the sowing of crops becomes less frequent, the seedlings die off. When sprouts and seeds have been damaged during transport, planting and other situations, there is an increased risk that they will be susceptible to bacteria and pathogenic fungi.

The greatest damage is caused by larvae of the 1st generation. The next generations are no longer capable of causing such harm to plants, since the larvae, as a rule, harm adult, mature cucumbers.

• Ways to eliminate the pest

It is very important to carry out such actions in order to eliminate the fly and its larvae:
In autumn, it is necessary to dig up the soil very deeply, and most importantly, to bury organic fertilizers (manure) there. If left on top of the ground, the strong smell will attract flies.

Weeds must be constantly fought. From the site where the cucumbers are planted, it is necessary to remove them.

Seeds of cucumbers should be planted in a timely manner. This will enable them to ascend quickly. Plants that have grown up are no longer interested in flies so much.

Before sowing, the seeds must be treated using insecticides. Very effective, for example "Fentiurama". For 1 kg of seeds, you need to take 3 g. For better fixation on the seeds of this remedy, the seeds are dipped in flour glue.

It is advisable to spray cucumber shoots with Iskra. 1 tablet of this drug dissolves in 1 bucket of water.

The harm that slugs do to cucumbers

Slugs are most active at night. This is their favorite time of the day, when they, without fear of the sun's rays, can feast on cucumbers. Fruits suffer the most from them, as slugs prefer to eat out the pulp from them. They also harm the crop by the fact that traces of their dark droppings and mucus remain on the cucumbers.

• How to deal with slugs in cucumber beds

An effective method is to sprinkle the soil with ashes mixed with lime, digging the soil all the time;
The area must be kept clean. All residues from plants must be removed and burned in a timely manner.

Slugs love to hide. Why not use it to catch them? In the morning they will crawl under cloth, pieces of paper, boards, which in the evening it is prudent to lay out under the cucumber bushes to attract them.

It is worth thinking about the use of chemicals when a huge number of slugs have divorced. To combat these pests, metaldehyde 5% has been created. If you treat the plants 2 times, you can not remember about slugs. It is necessary to scatter the granules on the soil. Slugs, having eaten the bait, will die.

Effective use of copper and iron sulphate, ground superphosphate, lime - fluffs. After the rain has passed, these products will not work, as these products are water-soluble

The number of clams in cucumber beds can be reduced by using their natural enemies. It is worth considering attracting “to help” brown frogs, legless lizards, toads and other lovers of eating slugs.

Birds are also not indifferent to them. Slugs attract the appetite of starlings, gray crows, blackbirds, magpies and other birds.

Funny pest - cucumber mosquito: control measures and prevention

Miracle Buttocks - 3-5 kg ​​of fresh strawberries every 2 weeks!

Miracle buttocks Fabulous collection is suitable for windowsills, loggias, balconies, verandas - any place in the house or apartment where the light of the sun falls. You can get the first harvest in 3 weeks. Miracle buttock Fairy collection bears fruit all year round, and not only in the summer, as in the garden. The life of the bushes is from 3 years or more, from the second year you can add top dressing to the soil.

Where is this insect not found! Its name is very funny, but when it appears in the greenhouse and begins its activity, no one is laughing here!

It kills mainly weak plants suffering from diseases of the root system. The mosquito is under the film, thanks to organic fertilizers, manure, onion planting material.

Cucumbers suffer not from mosquitoes, but from their larvae.

• Ways to kill mosquitoes on cucumbers:

It is necessary to plant seedlings of cucumbers only in a healthy form.

Actellik, Chlorophos and Iskra are those insecticides that have proven their effectiveness. To make a solution, dilute 1 tablet in a 10-liter bucket of water. This bucket is enough to process 100 sq.m. It does not hurt to carry out thermal sterilization of the soil.

Gall nematode: what harm does cucumbers, description and methods of control

This is a worm 1.5 mm long. His favorite habitats are: greenhouses, greenhouses. Having penetrated the roots of the plant, the nematode settles there.

• How to find out that cucumbers are infected with this pest

1. An infected bush of cucumbers lags behind the same in growth.
2. Harvest obtained in a reduced volume.
3. It can be observed that ugly “bumps” appeared on the roots - these are the places where nematode larvae ripen.

• What to do to destroy the worm on cucumbers:

It is difficult to eradicate a nematode if it has already appeared in the greenhouse. It is worth taking preventive actions:
In the garden, in the open field, where cucumbers grow, it is necessary to plant cabbage and garlic. Weeds, every single one, must be destroyed so that the nematodes have nothing to eat.

Every season they change the place where the cucumbers were planted, that is, follow the crop rotation.

The soil is watered with boiling water. Then cover it with a film for 2 or 3 hours.
As soon as pests that destroy cucumbers are found, it is necessary to remove the top layer of soil. Alternatively, the soil is frozen, but the worms may not die.
