DETAILED INFORMATION ABOUT LEPIDOCID AND INSTRUCTIONS FOR USE

Lepidocid is an insecticidal biological product designed to protect agricultural, forest and park crops from caterpillars of lepidopteran pests (silkworms, scoops, leafworms, moths, moths, moths, moths and others).

The active substance of the drug: crystals and spores of the microbial culture of Bacillus thuringiensis var. Kurstaki. Lepidocid P, developed by LLC PO Sibbiopharm, is produced by the Russian company August in the form of a powder and is packaged in 50 grams.

The drug Lepidocid, the price of which is more than democratic, is successfully used on agricultural land, in urban park areas and personal subsidiary plots. The most eloquently talk about the main advantages of the drug Lepidocid reviews of agronomists and gardeners. Their experience indicates that this tool:

It acts selectively due to the specific structure of the intestines of lepidoptera insect pests;

It can be used at any stage of plant development, which is especially important in places where people live compactly, in resort and nature protection areas;

Does not accumulate in fruits and plants, ensuring ecological cleanliness and good taste of products;

The exposure time of the drug is only five days, so the treatment can be carried out shortly before harvest;

It is well combined in tank mixtures with other biological products and chemical pesticides.

The drug Lepidocide is an insecticide containing a special protein toxin, which, when it enters the body of a pest, leads to complete paralysis of the gastrointestinal tract within four hours. A day later, complete bacterial septicemia occurs, insects are immobilized and stop eating. Their bodies are deformed, change color, and within a week there is a complete death due to the toxic effect of the drug Lepidocid for them. The use of the drug in high doses leads to a decrease in the survivability of subsequent generations.

The drug has a special smell that is not tolerated by butterflies, as a result of which their years and the number of eggs laid decrease.

In accordance with the conclusion of the Research Center for Toxicology and Hygienic Regulation of Biological Products of the Ministry of Health of the Russian Federation, Lepidocide is classified as hazard class 4 (low-dangerous). When used at recommended rates, the product is safe for the environment, humans, warm-blooded animals, fish and all insects except Lepidoptera.

Lepidocid: instructions for use

It is desirable to treat plants in a protective gown, gauze bandage, goggles and gloves at an air temperature of +15-35°C in calm, dry weather at any phase of plant development. It is forbidden to prepare the solution in food utensils. Do not eat, drink or smoke while working with the solution.

The best effect is achieved when processing in the early stages of the development of caterpillars. If the pests survive and egg-laying continues, and also if there is heavy rainfall immediately after treatment, it is recommended to re-treat after 6-8 days. The last treatment should be carried out no later than 5 days before harvest.

The consumption rate of the drug is 20-30 g / 10 l of water. Lepidocid is diluted in a small amount of water, after which it is mixed with the rest of the water. Before use, the working solution must be shaken. To increase the efficiency and prolong the duration of Lepidocide, it is recommended to add the "adhesive" Liposam (150-200 g/1 ha) to the working solution, which is preliminarily dissolved in water in a ratio of 1:1 and mixed until smooth.

The working solution is prepared on the day of treatment and must be fully used within 24 hours.

The drug is well compatible in tank mixtures with other biological preparations and chemical pesticides, and can be used to reduce the resistance of pests to the latter. If there are a lot of insects, it is recommended to add 10-15% of a chemical insecticide to the Lepidocide solution.

LEPIDOCID, sc(suspension concentrate)

Biological insecticidal product for protecting plants from insect pests.

ACTION AND BENEFITS

Effective against caterpillars Lepidoptera insects of a wide range of species (whites, moths, leafworms, meadow moths, moths, scoops, moths, silkworms, hawthorn, nun, American white butterfly, etc.)

Does not have phytotoxicity, can be used at any phase of plant development.

Has a selective effect, affects only certain types of insects, without harming beneficial insects and the environment. When used within recommended limits safe for bees and entomophages, for soil, for reservoirs, fish and hydrobionts, for humans and warm-blooded animals. Guarantees the receipt of environmentally friendly, safe for health products.

There is no resistance (addiction) in insect pests.

Does not accumulate in plants and fruits. Waiting period - 5 days, which allows processing even shortly before harvest.

The long-term practice of using Lepidocide in forestry and agriculture has shown the high efficiency of the drug in the fight against harmful insects (80-95%) and its safety for the beneficial entomofauna of biocenoses.

Lepidocide is a microbiological preparation. Its active basis is spores and cells of bacteria (Bacillus thuringiensis var. kurstaki), as well as the substance produced by them during their cultivation - delta-endotoxin in the form of protein crystals. Inert fillers provide safety and stability, spreadability and adhesion of the drug.

MECHANISM OF ACTION

The action of the drug is manifested when it enters the intestines of the caterpillar when it is fed. Endotoxin leads to general paralysis of the insect's digestive tract during the first 4 hours, general bacterial septicemia develops, caterpillars stop feeding and moving, and massively die within 3-7 days.

Aftereffect: sublethal doses of the drug cause a violation of the timing of metamorphosis, a decrease in the fertility of females and the viability of the next generations (anti-feedant and metatoxic effects).

In addition to insecticidal properties, Lepidocide has a repellent (repellent) effect.. The smell of the drug repels butterflies from the treated area, thereby reducing the number of oviposition, and reducing the likelihood of caterpillars appearing in this area again.

COMPATIBILITY

In the working solution, Lepidocid is compatible with most other biological products (growth stimulants, etc.) and chemical pesticides. Can be used to suppress resistance, resistance of pests to chemical pesticides.

APPLICATION

Method of application - spraying plants with a solution of the drug when pests appear, using any sprayers.

Processing should be carried out in dry weather at a wind speed of not more than 4 m / s, in the morning or evening. The optimum air temperature is 18-32°C.

In colder weather, the death of caterpillars is delayed, but the protective effect is still manifested due to a decrease in the intensity of feeding, slow development and partial death of caterpillars.

The working solution must be prepared before processing and used within 2-3 hours.

Solution preparation:

In order to avoid the germination of spores included in the preparation, the water temperature should not exceed 20°C. The preparation in the form of a suspension concentrate is simply diluted with water.

The maximum protective effect is achieved when plants are treated in the early stages of pest development (for caterpillars, this is the I-III age, when their body length does not exceed 10-12 mm). In the case of an extended hatching period for caterpillars, the plants should be re-treated after 7-8 days.

The last treatment can be done 5 days before harvest, for medicinal plants - 10 days.

Precautionary measures. Moderately hazardous substance (hazard class 4 for humans, class 3 for bees). It is practically not dangerous for bees, but the restriction of the summer of bees within 6-12 hours should be observed. When used at the recommended consumption rates, it is safe for humans, warm-blooded animals, fish, hydrobionts, bees and entomophages, for soils, water bodies, and the environment. Not phytotoxic, does not accumulate in plants and fruits.

Guaranteed shelf life in the original packaging is 1 year at temperatures from +5 to +30°C.

Each of us on our site is faced with certain pests that devour our crops and deprive plants of strength. For example, I eat plums with great care: no, no, and even a worm will come across, despite the fact that in the spring they were processed from pests.

And sometimes plants even die due to pests and diseases. So how do you deal with them?

We are all used to using chemistry, and it is known to be dangerous: both we and the environment suffer, in general - nothing good. Recently, biological products have become more and more popular - products based on living organisms: bacteria and bacterial viruses, antagonist fungi. You can also find drugs based on beneficial insects (acariphages and entomophages) or on biological toxins.

I know that agriculture is increasingly using complex microbiological fertilizers (for example, BisolbiFit): there you have protection, nutrition, and everything. Why are we, gardeners and gardeners, worse? Let's see what biological products can be used to protect plants in the country.

Bisolbifit

I'll start with him, because I know him better than others. It is a dry form of microbiological fertilizer. You can buy at retail only from Faberlik. I also recently found out that they now sell not only cosmetics)). In general, the drug is actively used in agriculture.

It stimulates the immunity of plants and protects them from fungal and bacterial diseases, such as, and so on. I read that it counteracts almost all fungal, bacterial and viral pathogens. Bacteria - they are also pests, only very small)).

The drug is effective for both treatment and prevention of plant diseases. The soil is inhabited by microorganisms that instantly wake up and begin to do their good deed.

What is the advantage: it can be used not only as a remedy for diseases, but also as a var for treating damage to trees. Efficiency has been proven by the relevant All-Russian Research Institute.

Fitoverm

This biological product was created on the basis of the waste products of soil microorganisms. It is very effective in the fight against all types of plant mites (my grapes still suffer from - I should test this remedy on it!), Cabbage scoop, sawflies and so on.

The agent is completely soluble in water and soil, does not pollute nature. Two days - and the result is obvious. What you need to know about the use of the drug? The effect occurs from 5 hours to 7 days, and the total duration of exposure after use is 20 days. If the weather is rainy, then less, so it is advisable to carry out processing in good weather.

Lepidocide

Another biological insecticide. Designed to combat caterpillars of lepidoptera insects: silkworm, leafworm, scoops, moths, cabbage and so on. The drug is also approved for use in suburban areas, in personal subsidiary plots.

Advantages of the preparation: it does not accumulate in fruits, it is not toxic. If used within the established norms, it is completely safe for both humans and bees. Can be used at any stage of plant growth.

Nemabakt

And this is an amazing drug. It is a round microscopic worm that lives in the soil and feeds on insects)). Very effective in the fight against larvae of the Colorado potato beetle and other pests. Gluttonous to the point of impossibility! Penetrates the larva, kills it and goes in search of new victims.

Yes, biological products - they are like that ... Like in a horror movie))) It's good that these worms are harmless to humans.

Advantages of the drug - a long period of exposure. In the summer, worms kill from 60-100% of the larvae, go into hibernation in the winter, and wake up again in the spring and get to work.

Well, let me tell you about one more drug. For an even score.

Bitoxibacillin

Another biological insecticide. Kills larvae of the Colorado potato beetle, cabbage moth, hawthorn, silkworm and many others. The nature of the action is intestinal. The drug disrupts the intestinal function of pests, reduces their nutrition, which leads to the death of the larva. 3-7 days - and the mass death of pests is guaranteed.

These are the drugs today. You can use them. I don't know why we continue to use harmful chemicals... Although there is progress. Take at least the saving crop of our tomatoes. It's also a biological product.

Friends, do you use biopreparations in the fight against pests and plant diseases?

The insecticide lepidocide is a biological preparation, the action of which is directed to insect caterpillars of various ages. It has a wide spectrum of activity, helps to protect fruit trees and shrubs, as well as vegetable and flower crops from lepidoptera insects. The use of lepidocide guarantees ultimately an environmentally friendly crop without harm to human health.

Article outline

Features of the drug

The biological product lepidocid was created on the basis of spores of beneficial bacteria that live in the soil. The active factor, which is their living cells and active waste products.

Lepidocid has an intestinal effect, which, when a pest enters the body, completely paralyzes the function of the gastrointestinal tract within 4 hours, and completely infects the body during the day. As a result, the insect cannot move and eat, which ultimately leads to a change in the color of the insect's body, as well as to its wrinkling. Complete death of the pest occurs within 1 week.

The use of the drug in maximum doses guarantees a decrease in the number of future generations of pests. A feature of this tool is a sharp characteristic smell that repels butterflies, which as a result reduces the number of eggs they lay.

In addition, the drug does not accumulate in the leaves and fruits of plants, and is not phytotoxic., which guarantees an environmentally friendly crop after its application. According to the research conducted by the Scientific Center of the drug lepidocide, the complete safety of this drug for human health, fish, warm-blooded animals and bees has been proven.

The release form of the drug can be of two types:

• suspension;
• powder.

Advantages and disadvantages of using

1. It is not phytotoxic.
2. The active substance of the drug does not decompose under the influence of high temperatures, which makes it possible to use it on hot summer days.
3. It is not addictive in pests, which allows the use of Lepidocid several times during the season.
4. The use of this tool does not affect the taste of the grown fruits.
5. It has a selective effect on pests.
6. Application is possible at different phases of plant growth, as the drug has a short waiting period of no more than 5 days.
7. It is compatible with many chemicals, and can also be used in combination with macro and microelements.

Along with all the advantages of this tool, there are also disadvantages of its use.

Main disadvantages

1. It does not have the ability to stick to foliage, so it is better to use it in combination with various types of adhesives, which will ultimately have a positive effect on the quality of the treatment.
2. The protective properties of the drug can be noticeably reduced under the influence of sunlight, so the treatment is best done in the morning or in the evening.
3. Not particularly economical to use.
4. The drug is stored for a short period of time.

Instructions for use lepidocide

According to the attached instructions for lepidocide, the consumption rate is from 20 to 30 g per 10 liters of water. To prepare a working solution, it is necessary to dilute the drug in a small amount of water until it is completely dissolved, and then bring the volume of liquid to the required amount. Before use, the resulting product must be shaken. In order to prevent the germination of live bacteria that are part of the preparation, water with a temperature not exceeding 20 degrees should be used.

The most effective treatment effect with this agent is achieved during the first three stages of caterpillar growth, that is, their body length should not exceed 12 mm. In case of prolonged oviposition and hatching of pests, it is recommended to re-treat after 6 days.

It is important to remember that the success of pest control largely depends not only on the drug used, but also on the physiological characteristics of the insect, so it should be borne in mind that lepidocid is especially effective on delayed larvae and caterpillars during their greatest appearance. It should also be understood that the exit of the larvae may not be at the same time, depending on the air temperature and the type of insect. The last application of the drug should be carried out at least 5 days before the harvest.

Since this drug is biological, the maximum effect of its action does not occur immediately, but the process has already been started.

1. First of all, the pest is paralyzed, as a result of which it loses the ability to move and eat, that is, it ceases to harm the plant.
2. Within 3 days after the procedure, about a third of the treated pests die; after 2 weeks - most, and re-treatment with the drug after 8 days leads to the death of 90% of pests.

A freshly prepared working solution of the drug is subject to direct use, since the diluted lepidocide agent retains its properties during the day. No deviations from the indicated dosage are allowed, otherwise this may affect the final result. The optimal temperature for processing is the range of 18-30 degrees, as it contributes to the active eating of foliage by pests.

Consumption rates of the drug for the protection of various crops

The use of the product may differ depending on the crops being processed.

vegetable crops

The use of lepidocide helps to protect various vegetable crops from such pests: turnip white, moth, meadow moth and others. The consumption rate is 20-30g per 10 liters of water. The use of the drug is recommended for each new generation of insects with an interval of treatments 1 time in 8 days.

Fruit crops and grapes

The use of the product for these types of crops is recommended after the completion of the necessary chemical treatments in order to preserve the resulting crop in the future. The maximum effect is given by the use of lepidocide for fruit crops against such pests:

• apple and fruit moth;
• American white butterfly;
• moth;
• leaflet;
• leaf fall;
• bunch leaflet, etc.

The consumption of the drug is made at the rate of 30 g per 10 liters of water. It is recommended to use against each new generation of insects with an interval of treatments 1 time in 8 days.

Cereal crops

The use of this product for grain crops is carried out to protect plants from the gray grain scoop. Processing must be carried out during the growing season at the first three stages of caterpillar development, that is, their body length should not exceed 12 mm. The dosage rate of the product is 30 g per 10 liters of water.

forest plantations

• Siberian silkworm;
• fir moth;
• green oak leaflet;
• gypsy moth;
• caterpillars, etc.

For these purposes, the manufacturer of lepidocide provided for the release of the drug in professional packaging. It also provides for the production of two types of suspensions of a concentrated preparation for large-scale aviation processing of forests and stationary spraying using generators. The consumption rate of the drug is 3 liters per 1 hectare of plantings. One-time use is allowed with timely processing.

medicinal plants

The use of the drug for these crops is carried out in order to protect them from such pests:

• mole;
• leaflet;
• goldtail;
• meadow moth, etc.

Security measures

The drug belongs to hazard class 4, that is, it is moderately dangerous for humans, but standard safety standards should be followed during processing. Do not allow the presence of children and pets during the procedure. The remaining solution is not subject to further storage and therefore must be disposed of.

A reasonable approach to conducting timely treatments, taking into account the physiological characteristics of various types of pests, as well as strict adherence to the given norms and conditions in the drug instructions, allows you to maximize the use of all the qualities of a drug of biological origin, which makes it possible to grow an environmentally friendly crop. This is also evidenced by numerous positive reviews about lepidocide amateur gardeners.

This biological insecticide contains a microbial culture called Bacillus thuringiensis var. kurstaki, as well as the substance delta-endotoxin produced by them under the guise of inactive protein crystals. Reliability and strong structure of the drug provide inactive fillers.

Peculiarities

Lepidocide lacks phytotoxicity. It does not accumulate in plants and fruits, which means that in the end you will get a harvest that is harmless to health. Studies of the drug carried out in laboratories prove its safety both for human health and for various animals. The drug is allowed to be used in summer cottages, vegetable and cultural fields, resort areas, parks, forest parks and forests.

Processing is possible during any stage of plant formation and 5 days before harvest. It is especially useful to apply the drug at the stages of flowering and pollination. The use of Lepidocide is possible against various types of lepidoptera: silkworm, moth, some species of whites, meadow moth, butterfly, leafworm, moth and other lepidopterous pests.

Lepidocide is commercially available in three versions:

• powder Lepidocid, P;
• suspension concentrate Lepidocid, SK;
• oil concentrate Lepidocid, SK-M.

How the drug works

The intestinal action of Lepidocide means that it is activated within 4 hours after penetration into the body of the insect. Activation of delta-endotoxin in the alkaline environment of the intestine leads to damage to the inner lining of the intestine of the pest. On the following day, the complete infection of the insect organism occurs. The pest stops eating and moving, can change color and change in size. Death occurs 3-7 days after spraying the plants. If the drug used is diluted in large doses, the likelihood of reducing the viability of subsequent generations of insects increases.

The characteristic pungent smell of Lepidocide repels butterflies and, accordingly, reduces the number of eggs they lay.

Application

Let's figure out how Lepidocid can be used. For different plants, there are their own standards for dilution and use of the substance, as indicated in the instructions:

• cereal crops usually suffer from the wrecking of the gray armyworm. The dosage of the agent is 1 liter per hectare of land (hereinafter referred to as l / ha). Spraying with an insecticide takes place during the growing season of plants during the first three stages of the formation of caterpillars, when their body length is no more than 10 mm;
• vegetable crops are attacked by many types of insects, for example, cabbage or cotton scoops, cabbage or potato moths, moths, moths, cabbage or turnip whites. It is recommended to spray with a dosage of 0.5-1 l/ha. Due to the frequent appearance of new generations of pests, it is important to treat plants at weekly intervals. It is good to protect crops of carrots, cabbage, potatoes and beets from the caterpillars of the meadow moth with lepidocide;
• the use of Lepidocide against silkworms, white butterflies, apple and fruit moths, fire bugs, land surveyors, leafworms, codling moths and golden tails will save fruit crops and shrubs. The drug should be used after the use of chemicals to save the crop. The drug is dosed at 1 l/ha, but not more than 2-3 l/ha. It is necessary to spray every generation of insects that grow every week. Lepidocid showed good performance in the fight against the pest against the bunch leafworm, which often attacks vineyards;
• in addition, Lepidocide has proven itself well for protecting dark coniferous forests from caterpillars of various lepidoptera insects, Siberian (sometimes gypsy) silkworm, fir moth, green oak leafworm, etc. The norm of application is 3 l / ha in one stage of processing. Dosage 1 l/ha - with a water consumption of 200-400 l/ha. The drug used for such purposes is available in professional packaging. The aerosol process uses a suspension concentrate, while the aerosol process uses an oily suspension concentrate.
