Gentle leaves of early shoots of vegetable crops (lettuce, radish, spinach, radish) and seedlings of cruciferous plants (cabbage, beets, trousers), characterized by a short growing season, from the first hours after landing in open sad They are attacked by small bugs, in which many novice gardens do not even pay serious attention.
A day later - two it turns out that the leaves of young plants are so badly damaged by these insects - cruscle fleaIt is worth the question even about replacing seedlings. These pests are widespread in our country (except for the Far North), significant harm is applied in the north of the European part, in the non-black-earth and central regions, therefore they are considered one of the most dangerous pests of cruciferous crops.
These small (2-3 mm in size) dark beetles jump sufficiently high like fleas, because of which they began to call them "Cruscle flew", although in systematics they belong to the family PHYLLOTRETA (Family Listy). In the non-black-earth zone, cruciferous cultures are amazed primarily six species of flew, although, according to some specialists, about 80% of the total number of these flews in the middle, northern and western regions of the country is a wavy (Ph.Undulata Kutsch). Wavy flea (2-2.8 mm) black, a yellow band on each outbreak outside with a deep excavation.
As soon as snow comes down, after leaving the wintering, which the beetles are carried out in secluded places of the household plot, most often under the vegetable residues and fallen leaves, in the surface layer of the soil of the garden, in the creams of greenhouses and greenhouses, on forest edges, they feed on cruciferous weeds ( Freedom, shepherd bag, surepice field, radish wild, jaggility, fuel tier). In the middle lane of the country, this period is usually at the end of April - the beginning of May. With the advent of cultural plants, the beetles are flying on their foliage, with which the top layer scrapes and stretch along the edges of the leaves of the deepening, as a result of which the leaves dry up with significant damage. On more gentle leaves of turnips and radish, they break through holes (with a diameter of 1.5-2 mm). In case of damage to the point of growth, shoots can easily die. These beetles are most active in the day of the day (periods from 10 to 13 am and from 16 to 18 pm), when drops of dew on the leaves are dried. Insects are particularly voracious in dry hot weather and are able to destroy completely young shoots of cruciferous crops in a matter of days (sometimes even before the cotyledons appear above the surface of the soil). This is explained by the increased biological activity of the flea at high temperature (20 ° C and higher) and the inhibited development of plants during drought, which is why they do not have time to "leave" from damage. With mass reproduction, cruciferous flews quickly rub the seedlings of cabbage, especially the first 10 days, until it passed on after disembarking into an open ground. Also dangerous damage to the beetles for young shoots of radish and radish in the phase of the seedlines and the first real leaves. In some cases, cruciferous flews attack and shrugged cruciferous seeds, after moving on buds, pods and leaves small (1.5-2 mm diameters) pits and significantly reducing their harvest. In cool and wet weather, their activity falls.
In the summer, the flea sometimes damage the summer sowing of radish, as well as cauliflower seedlings. Of the flower plants, the most suffering from this pest, are most often called Levko and Alissa.
Females lay minced yellowish eggs into the soil. For example, in the conditions of the Moscow region, a wavy flew is putting eggs, starting from the second half of June and until the end of July. Eggs (0.3-0.4 mm) light yellow, translucent, oblong-oval. Out of 4-10 days after the masonry of eggs (depending on weather conditions), the body is a thin, long light yellow with three pairs of chest legs. The hatched larvae in the soil eat 2-4 weeks with small roots or eat root roots at the root neck. After 8-12 days, new beetles come out. Pockery of larvae occurs in the soil. The new generation of young beetles is also powered on cruciferous cultures, and with the onset of cold weather goes to wintering. During the year, all types of cruciferous flews develop in one generation.
Measures fight against cruciferous flea Must fold from a complex of agropriates and methods of biological and chemical protection. In late autumn, there should be deep steaming of soil on the beds, where you grown cruciferous cultures to twist prepared wintering beetles on the surface of the soil - then they will die with the first cold. To prevent the mass appearance of a flea, it is recommended to destroy the weed vegetation in a timely manner in a timely manner (especially from the cross-color family), which is rising both on the site and on the periphery of the plots, on the side of the roads: flew on it and multiply. Early seedlings of cruciferous crops should be subded under cloudy weather when the beetles are not particularly active (seeds in the maximum early deadlines Through greenhouses and greenhouses). On the other hand, sowing turnips and tours in the middle and northern lane can be carried out at the later dates - in June, when the number of flea starts to decline.
In hot weather, ramps and landed seedlings are shaded, for example, large leaves of burducms. It is very important to ensure the conduct of agrotechnical techniques that accelerate the growth and development of young plants: feeding by navigas, Selitra, or other nitric fertilizers, regular watering and loosening. There is information that the spraying of the foliage of the dung alive and a solution of bird litter has a negative effect on the flea. More developed and severe plants are characterized by a greater resistance to pest damage. The leaf surface of the only appearing seedlings and small seedlings of cruciferous sprinkles sprinkle or her mixture with tobacco dust (1: 1). This procedure only temporarily scares flew from plants, so it is repeated several times (usually immediately after watering plants). On the panstones With cruciferous flews, you can fight, catching them on plywood shields, lubricated on top of sticky substances - special long-drying glue, resin or tar. The bottom side of the flap comes in contact with the plants is not lubricated.
With a high population of pests, adverse conditions for young plants or for large-scale seedlings, it is more expedient to spray one of the insecticides. As effective insecticides in the practice of the household economy, the trading network offers (at the rate of 10 liters of water): Fufanon, KemiFos, Iskra M, Aktellik. Consumption of the working solution is 1 l / 10m². Processing landings in the evening when flees are calmly sit on plants, but no later than 20 days before harvesting. Since some garden crops - salad, radishes, celery, parsley are beginning to eat in the beginning of summer, it is still not worth handling these landings with pesticides, it is better to spray plants with the influence of ash or decoction of tomato plants. From the evening, a glass of ashes poured 9 liters of water, stirred, until the morning they give to stand, after which the entire liquid is drained over the precipitate and filtered if necessary. Or such composition: 2 kg of residues of fresh tomato plants or 0.5 kg of its dry mass poured 5 liters of water, insist (3-4 hours), then boiled on weak heat (green mass - 30 minutes, dry - 2-3 hours hour ); Focus, diluted with water (1: 2) and soaps are added (20 g per 5 liters of solution). And plant plants against cruciferous flews.

As soon as the first signs of the presence of the fleece on the garden appear, it is necessary to immediately begin the struggle, otherwise you can stay without a crop.
Small sizes of bugs having a brilliant deployed back - this is a sufficiently harmful insect for the garden, which belongs to the family of leaf beetles. These insects are able to destroy not only the leaves, but also buds with flowers or pods.
These insects are called flew due to the features of their rear legs to have an emergency jumping that can be compared with grasshoppers or real fleas. In concern, these insects this feature is actively used.
What does it look like?
There are several types of insects to the number of cruciferous flew. Among them is a wavy, laid, black, glittering, blue and others.
In fact, they can be different colors: both black, blue or green and with a specific metal glitter or two-color tone - black with a yellow stripe over the wings.
Flying bug with a length of 1.5-3 mm, having an oval-oblong body, as well as the mustache, which correspond to the size of at least a third of the body.
What harm brings?
The larvae of the cruciferous flew is powered by the rather thin roots of plants than they interfere with the full development of the already young and weak stem. An example of insect vital activity can serve as ulcerative discrepancies of leaves, exclusive breakdowns, as a result of which the plant shores or completely dies.
Significant damage to the stalks and leaves contributes to the formations of ulcers, which are quickly becoming huge holes, seedlings can perish on days, especially if it contributes to sufficiently warm weather.
What cultures amazed?
When the surface on the surface reaches 15 ° C, representatives of the cross-color fleeper can be found on the cabbage. The risk group includes garden crops: mustard sheets, trouser, salad cress, radish and radishes, rape, young horseradish, turnip, spinach, etc.
The same group includes cultural floral plants, including left, rose, mattiola, etc.
Cruciferous flea on cabbage, radister, on eggplants
The cruciferous fleet on radish, eggplants and cabbage is quickly capable of multiplying and in a few days, if not significantly sang, then completely destroy these plants.
For earlier representatives of these cultures should be applied folk ways Wrestling and prevention. For later cultures, more aggressive chemical drugs can be used.
Measures to combat cruciferous flesh
The struggle measures are distinguished by agrotechnical, folk and with the help of chemicals.
Definitely correct statement that an effective way to combat a cross-tone flesh will be a thoughtful, integrated approach.
Depending on the results and the procedures already done, you can adjust the culture treatment recipe. The correct strategy will help to cope with pests, at this time, at the same time, efforts.
Dry pollination of leaves
Dry pollination is made using a gauze bag, shook over which early in the morning over the plant, you can adhere to the leaves of frightening dust. Spain dirty leaves are not very much like insect, due to which it is carried out by scaring.
You can fill the gauze bag with such mixtures:
- A mixture of wood ash and limestone puffs in a 1: 1 ratio.
- A mixture of ash with tobacco dust.
- A mixture of ash along with ordinary road dust.
Dry pollination between the rows can be done using tobacco dust or naphthalene.
Spraying with decoction and inform
To spraying, you can start, prepare solutions on the following recipe:
- Insist for two days, stredens in boiling water ash. For better efficiency, liquid or economic soap is added.
- Connect a glass of crushed garlic with the same amount of tomato meat leaves. This mixture is bred in 10 liters of water (slightly warm). The liquid soap is not more than 1st tablespoon. Spraying to carry out with a warm solution.
- 200 g tobacco is poured ten liters of water. This infusion is also worth adding soaps (1 tablespoon). Spray, predetermining this fluid.
- 9% Table Vinegar dissolve in 10 liters of water. Vinezus need a glass, and if it is not, acetic essence is suitable (on 2 tbsp. Spoons)
- Small-Capid Watering with Nasty Green Wormwood with Addition of Garlic (on 10 liters of water 100 g). Water preheast.
- Potato Botato (4 kg) boil in 10 liters of water. The fluid infusion is diluted by water. So influence effectively conduct spraying in the evenings.
Agrotechnical methods include recommendations such:
- Follow the regular and timely destruction of weedsthat apply to cruciferous (wild mustard, shepherd bag).
- Mandatory autumn pumping and plowing soil. This is due to the fact that the insect habitat has the upper layers of the soil, and to climb on the surface at night drops of temperature, it will die quickly.
- When planting seedlings of cruciferous crops, other varieties of cruciferous plants are satisfied, Which can allocate phytoncides (substances having a specific smell that scares the flea). These plants include potatoes, calendula, garlic, tomato, coriander, etc.
- Planting seedlings as early as possibleWhen a flea stays in a hibernation, or at the end of June, when a peculiar pause is formed between the generations of flew, and they will bring at least harm to plants.
- Sufficient culture care, ensure maximum watering, because this insect does not tolerate abundant humidity.
Adhesive traps
Traps are mainly used as auxiliary means in the fight against a cross-color flesh.
For greater efficiency, it is better to cook traps from small flap fabrics that need to be predetermined in diesel or automotive oil. They are laid out between the beds, turning on the other side in a few days.
If we swing with such velcro on damaged by flelling crops, they will start jumping in a panic and, accordingly, stick to the fabric.
Chemicals
Insecticides are quite effective, but provided that we are applied with the mandatory compliance with the rules of preparation, concentration and frequency of use.
Such high efficiency is given such chemicals as:
- "Aktellik";
- "Aktara". Here you can read.
- "Decis";
- "Bolkla";
- "Intavir";
- "Karate."
It should be remembered that by using household chemicals, you can get less potent result, and at the same time, it is less dangerous compared to chemical insecticides. For the preparation of solutions that can be used to combat a cross-color flecking, acetic essence can be used, the ammonia alcohol, even the shampoo for dogs is suitable.
Folk remedies
Folk remedies do not have toxic effects on plants, but have a negative impact exclusively on the insect itself.
TO people's methods The fight against fleet refer to:
- Discarding with various mixtures.
- Spraying herbs and tinctures.
- Mechanical insect caught. In this method, any devices will be good: from special or homemade traps to a car vacuum cleaner.
- Abundant watering with the addition of substances in water, which have a sufficiently sharp smell, discing the pest. To substances with a rather sharp smell include tincture of Valerians, flea shampoo sold in veterinary stores. With a fairly strong aroma there will be a solution prepared on the basis of Corvalol (10-15 drops on the water bucket) or aromatic fir oils or, as an option of pine (in the same proportion).
Prevention - Protection against Crucian Fleece
Nothing less harmful in numerous methods in the fight against malicious insects is not inventing as timely and high-quality prevention.
Preventive methods will help not only preserve the harvest, but also to improve its quality, because timely done procedures in the struggle against pest will avoid the use of more severe ways of struggle (chemical).
The methods of preventive struggle include:
- Adhere to certain landing time.
- Timely removal of cruciferous weeds.
- Humidity level support at a sufficiently high level.
- The shelter of cultures with nonwoven canvas (Spanbond, Loutrasil, Agriculum). These are fabrics that perfectly skip light, moisture and air. Insects are actually not able to break up under a dense shelter, due to which the protection is carried out.
- Using numerous folk remedies.
Methods for protecting garden crops diverse and fairly effective even without the use of potent chemicals. Every gardener for itself determines the set of most convenient highly efficient means.
Conclusion
In addition to the fight against a cross-color flesh, the modern garden has many different cases. It is not possible to deal with an exclusively struggle with one type of insects.
Timely prevention and knowledge most effective ways The destruction of a harmful insect will help optimally and with minimal cost Time and finance resources solve this problem.
Proper assessment of the situation, what the most acceptable way to fight will give a fast and excellent result will be the key to a good crop.
Such vegetable crops like chinese cabbage Early maturation, radish and arugula are the first delicacy for a cross-troop fleece. It appears at the moment when the plants are gaining strength and so - you can enjoy the spring salad from fresh greenery. This small pest is capable of spoiling a large amount of vegetable crops in a short time.
You can fight this insect in two ways: prophylactic measures and special means capable of scarying the pest. Experienced daches and gardeners try to engage in time to engage in prevention so that this insect does not appear on vegetable beds at all. If non-crude guests have already appeared on your land plot, then hope only for scaping drugs.
Compliance with landing time
Gardeners with extensive experience recommend landing vegetable cultures in early spring, at the very beginning of March, preferably in the greenhouse. Already by the beginning of May it will be possible to collect a harvest. At this time, no flea is already dangerous, as she likes to eat with young leaves.
If strictly adhere to landing timelines and plant cultures in early spring or in the middle of summer, then the plants will have time to achieve their maturity to the mass invasion of harmful insects or much later than their appearance. Such a landing will allow plants to develop without problems, gain strength and will provide an opportunity to cut a little delicate leaf mass, which is a big chance for saving vegetable crops.
Removal of cruciferous weeds
This method of struggle, though not easy, but very effective. The fact is that the flea, before the appearance of her favorite vegetable plants, it feeds on the weeds of the weeds - the shepherd bag, the reel and other representatives of the cross-tech. These plants appear earlier, and with them and flew. This is later she will move on vegetable beds.
The task of each gardener is to completely deliver its plot from these weeds. If there is no initial "nutrition" for the pest, then there will be no pest in the country too. He will go to look for a delicacy on other gods.
High humidity maintenance
Favorable conditions for the cruciferous fleece is hot and dry weather. It is at such a period that she massively appear on the plot. But water, wet soil and increased humidity for it are not acceptable. This is necessary to use as preventive measures. Vegetables need to plant on the most raw soils at the cottage, watering to spend - abundantly and every day. And even better, if there are plants with special organic solutions, and not just the usual estate water.
Shelter nonwoven fabric
Over the beds it is necessary to build small arcs and cover them with any material that will be well to pass the air, light and moisture (for example, agricultural, Loutrasil or nonwoven canvas). Under such a covering, the cross-color flea practically does not penetrate. The structure can be removed when cultures will reach certain maturity and the fortress.
Mixed planting with phytoncide plants
The flea is a pest who instantly reacts to strong and sharp smells. Take advantage of this weakness - put on a garden with a cabbage garlic or dill. The cultivation of cruciferous crops of a later landing is desirable to combine with fragrant floral cultures (for example, with calendula or velvets). Using those mixed planting, Plants will definitely remain safe.
If for some reason, the joint landings did not take place, then vegetable cultures can be protected with a bitter flavor aroma. Bundles of this plant are recommended to lay out between rows, but they will be frequent, almost daily, update.
Discarding against a cross-color flea
The cruciferous flea loves to eat with gentle young and clean leaves. Therefore, in order to conserve plants, they need to "pollute" for a while. As such a protective "powder" you can use woodwood Or her mixture with tobacco dust (you can even mix ash with road dust), as well as ground red pepper.
You can do and dubbing the soil areas between vegetable rows. For this, the pepper powder, tobacco dust and naphthalene will also fit.
"Powder" is applied to wet plants with a sieve or a small gauze bag. Moisture contributes to the good and long adhesion of any small particles. You need to repeat this procedure every day, as watering wash off protective pollination.
Some daches and gardeners are used to dust the dors or haired lime.
Spraying against a cross-color flea
The easiest solution for spraying cruciferous crops is prepared from 5 liters of water, 1 cup of ash infusion and about 50 grams of crushed tar soap. Before use, the solution must be forced within two hours. The droplets of this solution on the plants will be for a cruciferous flea of \u200b\u200ba real trap. Pests will stick to the leaves and after some time to die, unable to get out.
You can cook other solutions to combat the flesh, for the preparation of which you will need to spend a little more of your time.
- Recipe number 1. It will take: 5 liters of water, 1 teaspoon of liquid economic soap, a glass of garlic and a glass of glasses of tomatoes trees. First you need to grind vegetable plants in the meat grinder, then mix everything with water and soap. Before use, the solution is desirable to strain.
- Recipe number 2. It will be necessary: \u200b\u200b1 Water bucket, 1 tablespoon of soap and 500 grams of crushed dandelions (roots, stems and leaves). A plant cleaner is added to the water, filled with soap and the solution is ready.
- Recipe number 3. The order of preparation and proportions of the spraying solution is the same as in the recipe number 1 and No. 2, only the main component is the dried tobacco in the amount of 200 grams and is used hot water.
- Recipe number 4. Acetic spraying is carried out by a solution prepared from 5 liters of water and 1 tablespoon of acetic essence (or 9% vinegar in an amount of 100-120 milliliters). It is processed only by the leaves of plants.
- Recipe number 5. 500 grams of freshly wormwood must be pouring with a small amount of water and boil for 15 minutes. After complete cooling, the infusion need to add 50 grams of garlic (scrolled to the meat grinder), thoroughly stirring and strain through the sieve. In the resulting liquid, 5 liters of water are added and proceed to the spraying procedure.
- Recipe number 6. The following solution is applied to plant processing in the evening. The main component is potato or tomato tops in the amount of 2 kilograms. Plants are poured with 5 liters of water, boiled a few minutes, cool and filter. Before use, the solution is diluted with water in equal parts.
Conditions of cruciferous fleece
Methods of such hunting are several. The most basic is catching insects on sticky substances and adhesive materials. A substance with high adhesiveness can be resin, solidol, machine oil. Groaning one of these substances a piece of cardboard or tight fabricAttached to the anticipation, you can walk along the conduits of cruciferous plants. Worried bouncing insects will definitely get into the sticky trap. You can arrange several such traps directly on the beds and between them.
You can catch these pests with the help of a portable vacuum cleaner intended for the car.
Watering from a crucian flea
Some of the most dangerous radishes are cruciferous flea. They live everywhere, so everyone can meet with them.
Let's deal with what can do with these pests and which there are ways to deal with them.
Description of the pest
Crucifier has a very small size - no more than 3 mm. Often, gardeners do not pay attention to them, because the bugs are so small, which merge from the ground. To remain imperceptible to them helps black color, but some kind of fleaings have yellow stripes on the back. 
The bugs wake up after the winter immediately, as soon as the Earth fatters. Adult individuals in spring eaten mainly (wild radish, fuel, surepitsa, and others, and then black flews are moving to radishes and other cultural plants family of cruciferous.
Possible consequences
For radishes, the fleece is very dangerous - they will emit thin and gentle leaves to the holes, after which they dry. A large number of The flea can destroy the whole rat in the garden for 2-3 days: adult bugs will open the leaves and eat the skin on the stalks, and the larvae of the plant's roots in the meantime. 
It is necessary to fight with a cross-tone flesh on a radister immediately after you noticed it, and even better to carry out prevention during the planting of the plant.
Did you know? Israeli farmer Nissan Timir raised the largest radister. She weighed 10 kg and listed in the Guinness Book of Records.
Signs of the cruciferous fleece on the radister
The main signs of radish infection with a cruciferous flesh are:
- the presence on the plant of small bugs, which jump in all directions, if you disturb the leaf;
- leaves of plants thin and skeleton;
- the presence of holes on the leaves;
- mining of leaves (in the leaves sprinkled through the leaves).
Methods of struggle
These insects are fighting both chemical and folk remedies. If the owner of the site is rare in the country, it will be more convenient for it to use chemicals to combat fleas.
But gardeners who are constantly on the plot can defeat bugs and folk remedies.
Folk remedies
You can get rid of flea on the radister using such a means as ordinary table vinegar. In the bucket of water you need to dilute the bottle of vinegar and treat the affected culture in dry weather. Well helps in the fight against pest tincture of 500 g roots and leaves and water buckets.
Important! Radish is a rapid culture. If there is no need, you should not apply chemicals, as they can accumulate in the plant.
Also for the decoction of tomato or potato tops, which can be obtained if the bushes are pausing. In this decoction you need to add half a piece of grazing household soap. 
A large number (2-4 kg) of fresh or dry tomato or potato tops need to be mashed within four hours in 10 liters of water, then boil, cool and strain. Then the decoction is diluted with water 1: 1.
If an extra ready-made decoction remains, you can not pour it out, and save until next season, closing it tightly with a lid.
Well helps the supper of the soil on which radishes grows, naphthalene or tobacco dust. This powder will be a good breakfast protection and useful fertilizer at the same time. The procedure will be effective if you do every 4-5 days at least three times.
Fleece on a radister can be overcome by several more folk remedies. The tops of the plant can be sprinkled with early in the morning for the decaying dew with black ground pepper or hawed lime. Experienced gardeners come up with various traps for insects. 
Often there are special canopies above the beds, the lower side of which is lubricated with something sticky (, solidol, resin). After a few days, the fleece is sticking to the trap and it will be necessary to change it to the new one.
Important! During pollination of the radish, Naphthalene needs to use protective masks, as its pairs are dangerous to human health.
Motorists to combat insects can use pieces of fabric moistened in old car oil. Slices of fabric are laying out on cardboard sheets between Redish beds for 2-3 days. After they need to be turned over to the other side and leave for the same period. Traps are folded at a distance of 4 meters from each other.
Chemicals
Before splashing Redish from fleece, it is worth trying to fight her natural means. If they did not help, you can proceed to the use of special preparations. 
The most effective chemical means of combating insects are:
- "Intavir";
- "Bolkla";
- "Karate";
- "Sherpa";
- "Tabazol";
- "Kaiser";
- "Zolon".
Important! Insecticides are used only on the redirefish of medium grades (25 days ripen) and only until young shoots. Otherwise, there is a high probability of crop death.
It is important to take into account the desired concentration of drugs, which is always written on packages and for all substances is different. For example, 20 ml of AKTELLIK means need to be breeding on 10 liters of water. And if you use "karate", there will be 2.5 ml on the same amount of water. 
Before processing all germs, it is necessary to check the drug on one plant. Then you need to watch the processed day of the day and, if its condition did not deteriorate, you can continue to process the culture. Spray with chemicals usually in the evening when the sun has already gone. It was at this time that the short-circuit flew in a state of calm is sitting on the leaves of radishes. It is advisable to see the weather forecast for the night and the next day to make sure that there will be dry weather. If the precipitate still passed, you need to repeat the processing process.
It is important to remember the observance of all the rules of security during the processing of plants of chemistry in order not to accidentally choose and not get chemical burns. Collect and eat radishes, which was processed, can be used only after a month from the day of spraying. 
Prevention of pest
The appearance of a cruciferous fleece on the radister is easier to warn, than then try to fight with it with her. Cruciferous flews are afraid of a wide variety of odors. For the prevention of the appearance of an insect, radishes should be surrounded by such plants:
- tansy;
»Preparations
As soon as the first seedlings appear on the beds, or it is planted for a permanent seedlings, the sprouts are exposed to the invasion of a huge number of small bugs of black color - cruciferous flew. It happens that they are enough for several days to bring all plants into disrepair for further growth.
- wavy;
- uncommon;
- lED;
- blue;
- black and others.
Beetles are painted in black, blue, green tones, there are two-color insects - on a black background, a winding strip of a yellow shade is clearly visible. Insect length is different - from 1.8 to 3 millimeters. The pest can be found in almost every area of \u200b\u200bthe country, except the northern. He is rightfully considered the most dangerous enemy For cruciferous plants.
Wintering adults are capable of remaining on the beds with plants that felt the leaves, in the upper layers of the earth, greenhouse and greenhouses. They wake up early in spring when it hips the soil. As a rule, this time is accounted for April - May.
At the same time, the diet of their nutrition is weeding plants, but as soon as seedlings appear on the beds, the fleece goes into garden sections, damaging the foliage of plants, leaving the recesses that resemble ulcers. On the young leaves, the flew hole breaks through through. The peak of their activity falls on the morning and evening.
The female lays eggs in most cases directly to the ground. The resulting larvae hide the first time in the soil, several weeks feeding the roots and root roots. Then they pumped up, and weeks in a half you can observe the emergence of a new party of young beetles, actively destroying plants.
What plants amazed pests?
How to deal with flesh in the garden?
Experienced gardeners will always be able to protect their garden from the pest using not only chemical preparations, but also folk tricks.
The use of special drugs
For the destruction of the fleece, many insecticidal funds are quite suitable:
Any of the drugs can be purchased in a specialized store. Processing them of beds is best carried out in the evening when the sun has already gone. The flea still continues to be on the foliage.
Working S. chemical compositionsOne should strictly adhere to the requirements of the instructions for their use.
The use of folk remedies
— wet environment - The easiest way. One should only abundantly water the beds, as the flea does not tolerate raw places;
— Method of dry pollination of foliage - performed by a gauze bag that must be shaking over plants. In the bag, you can lay wood ash in pure form or with adding tobacco dust. Best of all, such procedures are performed in the morning, so that the scaping agent is settled on the humid on the foliage dew. On the dirty plants, the flea fears to sit down. By the way, the aisle can be treated with naphtalin or tobacco dust;
— the use of infusions and herbal decoctions:
- the ash at the rate of 1 to 3 is sealed with boiling water, insisted for two days. In the infusion add a household soap;
- garlic and tomato steps (one glass) are skipped on a meat grinder. Everything is divorced in a declined water bucket, fastened. You need to add a spoonful of soap. Before spraying, the solution must be slightly able to heat;
- the leaves and roots of the dandelion in the amount of five hundred grams are skipped on the meat grinder, everything is poured into a bucket with water, joined. It remains to pour the soap spoon, and you can use infusion for processing;
- two hundred tobacco grams flooded with hot water (ten liters). It is necessary to pour the liquid soap to the resulting mixture;
- a glass of ordinary vinegar pour into a bucket with water. You can replace it with a couple of spoons of the essence;
- green wormwood insisters, you can add garlic crushed into the water (one hundred grams per bucket) into the water. Peresya infusion, they should water small droplets of the plant;
- four kilograms of potato tops are poured ten liters of water, everything is brought to a boil. The decoction is allowed to cool, filter, diluted twice with water. Processing must be spent in the evening;
- the same recipe, only tomato stepsing are used.
Easy tool - to cover the beds with seedy underwent nonwoven materials. They perfectly skip lighting, water and air, reliably protect shoots from flew.
Make from dense material flags, secure them on sticks, spread with something sticky - resin or solidol. The flags need to be waved over the landings, barely assignt leaves. The procedure is recommended to spend the day when it is very hot.
Moching a piece of fabric in a machine oil, put it next to the bed. Best of all, if such traps are arranged with a three-meter interval. After a couple of days, the fabric simply turn to the other side.
Preventive methods of pest appearance on plants
Become to warn the appearance of the pest. It is necessary to constantly remove cruciferous weed herbs by all available ways.
In the autumn season, the garden must be switched. This will help get rid of the fleece, which will be on the surface and in winter time freeze.
It is not necessary to neglect the filtering of plants by organic compositions, regular irrigation, soil looser. All this will help speed up the development of plants.
It is not necessary to neglect the weather conditions - to sow early cultures while the flea is still sleeping, or to perform it in June, when the pest activity is reduced.
Remember that fighting flesh must! This will help you to preserve the future harvest not only vegetables, but also berries, strawberries, for example. If you do not take timely measures, then all plants will be destroyed at the early phase of their growth.
