The insecticide lepidocide is a biological preparation whose action is aimed at insect caterpillars of various ages. It has a wide spectrum of action and helps protect fruit trees and shrubs, as well as vegetable and flower crops from lepidopteran insects. The use of lepidocide ultimately guarantees an environmentally friendly harvest without harm to human health.
Article outline
Features of the drug
The biological product lepidocide is created on the basis of spores of beneficial bacteria that live in the soil. The active factor is their living cells and active waste products.
Lepidocide has an intestinal effect, which, when ingested by a pest, completely paralyzes the function of the gastrointestinal tract within 4 hours, and completely infects the body within 24 hours. As a result of this, the insect cannot move and feed, which ultimately leads to a change in the color of the insect's body, as well as to its shrinkage. Complete death of the pest occurs within 1 week.
Using the drug in maximum doses guarantees a reduction in the number of future generations of pests. A special feature of this product is its sharp characteristic odor, which 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 also not phytotoxic, which guarantees an environmentally friendly harvest after its use. According to the research conducted by the scientific center of the drug lepidocide, the complete safety of this drug for the health of humans, 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 use
- Not phytotoxic.
- The active ingredient of the drug does not disintegrate under the influence of high temperatures, which makes it possible to use it on hot summer days.
- It does not cause addiction among pests, which allows the drug lepidocide to be used several times during the season.
- The use of this product does not in any way affect the taste of the grown fruits.
- Has a selective effect on pests.
- Application is possible at various phases of plant growth, since the drug has a short waiting period of no more than 5 days.
- 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
- 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.
- The protective properties of the drug can be noticeably reduced when exposed to sunlight, so treatment is best carried out in the morning or evening.
- It is not particularly economical to use.
- The drug is stored for a short period of time.
Instructions for use of 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, then increase the volume of liquid to the required amount. The resulting product must be shaken before use. To prevent the germination of live bacteria that are part of the drug, you should use water with a temperature no higher than 20 degrees.
The most effective effect of treatment with this product is achieved during the first three stages of caterpillar growth, that is, their body length should not exceed 12 mm. In case of prolonged egg laying and pest hatching, 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 lepidocide is especially effective on deposited larvae and caterpillars during the period of their greatest appearance. It should also be understood that the larvae may not emerge at the same time, depending on the air temperature and the type of insect. The last use of the drug should be carried out at least 5 days before the start of harvest.
Since this drug is biological, the maximum effect of its action does not occur immediately, but the process has already begun.
- First of all, the pest is paralyzed, as a result of which it loses the ability to move and feed, that is, it ceases to harm the plant.
- Within 3 days after the procedure, about a third of the treated pests die; after 2 weeks - most of them, and repeated treatment with the drug after 8 days leads to the death of 90% of the pests.
A freshly prepared working solution of the drug can be used directly, since the diluted lepidocide product retains its properties throughout the day. No deviations from the specified dosage are allowed, otherwise this may affect the final result. The optimal temperature for treatment is the range of 18-30 degrees, as it promotes active eating of foliage by pests.
Consumption rates for the drug to protect various crops
Application of the product may vary depending on the crops being processed.
Vegetables
The use of lepidocide helps protect various vegetable crops from the following pests: turnip moth, 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 a treatment interval of 1 time every 8 days.
Fruit crops and grapes
It is recommended to use the product for these types of crops after completing the necessary chemical treatments in order to preserve the resulting harvest in the future. The maximum effect is obtained by using lepidocide for fruit crops against the following pests:
- apple and fruit moths;
- American white butterfly;
- moth;
- leaf roller;
- leaf fall;
- cluster leaf roller, etc.
The drug is consumed at the rate of 30 g per 10 liters of water. It is recommended to use it against each new generation of insects with a treatment interval of 1 time every 8 days.
Cereals
This product is used for grain crops to protect plants from the gray cutworm. Treatment must be carried out during the growing season during the first three stages of caterpillar development, that is, their body length should not exceed 12 mm. The dosage rate for the product is 30 g per 10 liters of water.
Forest plantations
- Siberian silkworm;
- fir moth;
- green oak budworm;
- gypsy moth;
- caterpillars, etc.
For these purposes, the manufacturer of lepidocide has provided for the release of the drug in professional packaging. It is also planned to produce two types of concentrated drug suspensions 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 if processed in a timely manner.
Medicinal plants
The use of the drug for these crops is carried out in order to protect them from the following pests:
- mole;
- leaf roller;
- goldentail;
- meadow moth, etc.
Security measures
The drug belongs to hazard class 4, that is, it is moderately dangerous to humans, but during processing one must adhere to standard safety standards. Do not allow children or pets to be present during the procedure. The remaining solution cannot be stored further and must therefore be disposed of.
A reasonable approach to carrying out timely treatments, taking into account the physiological characteristics of various types of pests, as well as strict adherence to the given standards and conditions in the instructions of the drug, allows for maximum use of all the qualities of the drug of biological origin, which makes it possible to grow an environmentally friendly crop. This is also evidenced by numerous positive reviews of lepidocide by amateur gardeners.

Lepidocide translated into Russian means destroying caterpillars. The pesticide with this name is, indeed, used to combat caterpillars and false caterpillars of harmful insects. The raw materials for the drug are produced in the Russian Federation by Sibbiopharm LLC, a long-established and well-established developer and manufacturer of biological products for agricultural machinery. Products directly from Sibbiopharm (see figure) are intended mainly for large-scale agricultural machinery, but based on the same raw materials, leading manufacturers of agrochemicals also produce many biopesticides for private farms. The drug Lepidocid also contains a long-established and well-tested “active ingredient” – the bacterium Bacillus thuringiensis var. kurstaki.

Preparative forms
The insecticide Lepidocide is available in 3 formulations:
- P(powder; former designation D – dust): strain BA-3000 EA/mg, titer of at least 60 billion spores/g. Packaging from the primary manufacturer in multi-layer sealed bags of 10.15 and 20 kg. Storage temperature before opening the package is from –30 to +30 degrees Celsius, i.e. Lepidocide P can be stored frozen. Shelf life up to 18 months. The cost of 1 kg of the drug wholesale is approx. 600 rub. Despite the higher content of the active principle, Lepidocid P is no more active than other preparative forms, because A significant proportion of bacteria do not develop from spores when using the drug. The activity of the drug begins to appear after 1-3 days of its use. To prepare the working fluid, you must first prepare a mother solution (see below). In general, Lepidocid P is a drug for the northern regions of growing target crops, where pest activity is lower.
- SK(suspension concentrate): strain BA-2000 EA/mg, titer of at least 10 billion spores/g. Primary packaging in PE canisters from 20 to 50 (typical – 28 l canisters). Shelf life up to 12 months. at temperatures from +5 to +30 degrees. Wholesale price approx. 210 rub./l in terms of a 28 liter canister. The activity of the drug manifests itself during daylight hours. The working solution can be prepared directly in the sprayer tank. Add approx. to the finished working fluid. 20 ml/l of any adhesive for agrochemicals or liquid household chemically neutral detergent (shampoo, etc.). In terms of its set of qualities, it is a more “southern” drug for regions where there is a high probability of a sudden mass invasion of pests.
- SK-M(modified suspension concentrate). All basic data is the same, but the wholesale price is approx. 250 rub./l per canister. The manufacturers, their contractors and distributors do not specify what the modification is. If you added an adhesive to the concentrate, it becomes a bit expensive. It is possible that the following serotype of bacteria was used, but the cultivation and mass production of serotype IV Bacillus thuringiensis var. kurstaki also cannot find reliable information.
Note: The serotype of pathogenic bacteria is, in general, the complex of their defense mechanisms against a specific set of antibodies of host animals. They also protect themselves by developing resistance to diseases; For pests, this is analogous to resistance to synthetic pesticides. Serotypes of bacteria that are pathogenic pests are improved through targeted selection. Currently, Bacillus thuringiensis var. is produced for agricultural purposes. kurstaki serotype III.
Advantages and disadvantages
The advantages of the insecticide Lepidocide are common to biological products:
The disadvantages of Lepidocide are also due to its biological nature:
- Does not have translaminar and systemic activity, because it occurs at the molecular level;
- It acts on objects of elimination only by the intestinal route;
- It acts rather slowly - the caterpillars stop feeding and die within 2-3 days;
- Does not affect adults (reproducing and migrating generation) of pests);
- It is also ineffective against the larvae of Coleoptera, Diptera and other taxonomic groups - Bacillus thuringiensis is a specific pathogen of lepidoptera and certain species of lacewings;
- Useless against sucking pests, only affects gnawing ones;
- It is quite effective only against immature caterpillars and younger false caterpillars, or against small tender caterpillars;
- Secretive caterpillars (codling moths, tree moths) are attacked by the youngest only in the wandering phase, when they are still crawling around the plant, “testing their teeth” where it would be more convenient to bite deep;
- Does not destroy elimination objects 100%, i.e. more than one application per season is required;
- Long time before rain - at least 24 hours;
- The drug emits an unpleasant and rather persistent odor, which, however, is not transmitted to agricultural products (subject to a waiting period);
- When using biological products and pesticides on the same farm, separate storage facilities must be installed for them.
Effect on pests
Composition of the insecticide Lepidocide is a mixture of spores of Bacillus thuringiensis var. kurstaki and microcrystals (or their suspended solution) and enzymes - products of their vital activity. A pest that has tasted the drug is first affected by fermentation enzymes: they ferment (without releasing gases) the nutrients eaten by the same pest (glucose, maltose, ribose, trehalose, fructose and starch). In the digestive tract of the pest, instead of “delicious”, a mixture of substances that are indigestible and toxic to it is formed.
Bacteria then hatch from the spores; in the intestines of young caterpillars, the conditions are suitable for them: the pH is within acceptable limits, and enough oxygen enters through the thin delicate integument and with food (Bacillus thuringiensis aerobes). Living bacteria begin to secrete protease enzymes that decompose casein and fibrin proteins, and substances that cause β-hemolysis of hemolymph, a fluid that replaces blood in insects. Simply put, the caterpillar ulcerates from the inside, it begins to have profuse internal hemorrhages, and it dies.
In “old” and large caterpillars, the chitinous lining of the digestive tract is too dense, and the hatched bacteria die from lack of oxygen. Such caterpillars that “grab” Lepidocide end up with indigestion. But because of this, most of them cannot accumulate enough fat body for metamorphosis into imago, so Lepidocide indirectly reduces the number of imago.
Note: in this way, another common property of biological products is manifested - a relatively weak initial, but long-lasting, well-regulating effect on pests. All the benefits of biological products appear only when they are systematically used year after year over large areas. For farmers, accustomed to fearing the resistance of pests and the harmful after-effects of pesticides on people and biocenoses, this circumstance prevents them from appreciating all the benefits of biotechnologies.
Precautions
Security zones for working with the insecticide Lepidocide are established as follows:
- Apiary – 1.5 km (limit the flight of bees to 48 hours).
- Reservoirs, open sources of water supply - according to their water protection zone.
- Children's, medical and recreational institutions, sports grounds, public recreation areas - 150 m.
- Residential buildings, food storage facilities, premises and areas for keeping pets - 15 m.
- Other outbuildings – 5 m.
It is permissible to use minimal PPE for working with the drug: work clothes and shoes that completely cover the body, protective gloves. When treating trees with a boom sprayer (above in the figure on the right), it is highly advisable to wear safety glasses and a gauze bandage or a simple anti-dust petal respirator. If you work with a “gun” injection sprayer, then it is better to wear waterproof overalls (below in the figure) or put a plastic raincoat over your clothes. The fact is that the unpleasant odor of the drug is quite persistent. If clothes become saturated with it, they will have to be aired in the sun for several days, and still, the smell will be felt for a long time.
If the drug gets on the body, it should be washed off and washed; Wash clothes wet with working fluid. In case of contact with eyes, rinse them with water. If ingested, drink 2-4 glasses of water, induce vomiting and take 3-4 tablets of activated carbon.
Acute drug poisoning is unlikely and results in indigestion. Theoretically, in case of poisoning with Lepidocide and other drugs containing Bacillus thuringiensis, phenomena similar to the effects of the venom of viper snakes are possible: skin ulceration, hematomas, internal hemorrhages, accompanied by severe sharp or nagging pain, but it is impossible to swallow the amount of the drug required for this - long before it will turn you inside out . However, you must follow the general safety rule when working with pesticides - if you feel any discomfort, you should immediately stop working and consult a doctor.
Lepidocide is stored under the usual conditions for pesticides: in a separate non-residential premises, inaccessible to children and animals. But to the usual set of things that are unacceptable for storage there: food and food products, medicines, clothes and shoes (including work shoes), pesticides of non-biological origin are added (biological products can be stored together). Neutralization of spilled powder in the household plot - collect it with a broom or brush into a dustpan and throw it in the trash. If spilled on the floor, collect it with a disposable rag, throw it in the trash, and wash the floor. No special neutralization of spilled or spilled material is required. In large agricultural farms, disposal of empty containers and neutralization of spilled/spilled containers follows the general rules.
Application procedure
The stock solution of Lepidocide P is prepared with continuous stirring for approx. in half a liter of lukewarm water; the dose of the drug is administered gradually. After preparing the solution, it should be allowed to stand for 10-15 minutes so that the spores “wake up” and become more active, and only then should it be introduced into the tank. The working suspension of Lepidocide SK and SK-M is prepared directly in the tank of the device. Don't forget to add adhesive!
It is advisable to carry out the treatment on dry plants in the morning: at night the pests do not feed and a significant proportion of the bacteria will be wasted. Control of consumption during manual spraying - over the area, until a continuous film of the drug is formed, but without dripping drops. Time before rain – 48 hours.
Instructions for using the bioinsecticide Lepidocide on private plots are given in Table. Apple trees need to be treated especially carefully against codling moths: spraying should be carried out when small “worms” (stray caterpillars) crawl on the leaves and fruits. If they have already begun to bite into it, a good share of the harvest will still be lost.
Note: Lepidocide for use in private household plots on edible nightshades (potatoes, tomatoes, vegetable (sweet) peppers, eggplants) is not registered, but there are no fundamental contraindications to this, and private gardeners successfully use the drug, for example, on peppers, see video:

In conclusion
It was mentioned above that not only the agricultural strategy, but also the very way of thinking of the owners (owners, managers) in an eco-farm using biological products should be different from that of those “using chemistry.” Therefore, in conclusion, we offer a video guide on the methods and rules for using biological products for agricultural technology:
Video: about the use of biological products
"Lepidotsid" is a unique biological insecticidal preparation designed to protect agricultural, park and forest crops from numerous pests.
In the material we will consider the composition of the drug, its principle of action, regulations and procedures for carrying out treatments, compatibility, safety issues and restrictions.
“Lepidotsid” translated into Russian means “destroying caterpillars.” Its main purpose is to fight caterpillars and false caterpillars. By its effect on organisms it is classified as an insecticidal preparation, by its method of penetration it is classified as an intestinal pesticide, and by its origin it is classified as a biological insecticide.
The range of effects on insects is wide, this includes most gnawing insects:
- whites,
- scoops,
- moths,
- fruit moths,
- silkworms,
- trees,
- sawflies,
- fire,
- leaf rollers.
Composition and active substance
Composition of "Lepidotsid" - a mixture of spores Bacillus thuringiensis var. kurstaki and microcrystals (or their suspended solution) and enzymes - waste products of bacteria.
The concentration of bacteria in dry form is BA-3000 EA/mg, titer is at least 60 billion spores/g, and in liquid form - BA-2000 EA/mg, titer is at least 10 billion spores/g.
Currently, serotype III of Bacillus thuringiensis var. is produced for agrotechnical plant protection. Kurstaki.
Mechanism of action
Bacteria enter the body of an insect (caterpillar) through food. Initially, fermentation enzymes begin to work, which ferment the nutrients eaten by the insect (glucose, ribose, fructose, maltose, starch, etc.) and form toxic substances. Further, through sporulation, a new colony of bacteria arises, which actively develops in the gastrointestinal tract. Bacteria live on oxygen consumed through a thin chitinous film. During their life, bacteria begin to actively secrete protease enzymes, which disrupt the structure of proteins and substances that cause β-hemolysis of hemolymph (a fluid that replaces blood in insects). Thus, the insect begins to internally “bleed” and the insect dies.
Varieties and formulation
The biological product is produced by various Russian manufacturers, but the main component is produced by Sibbiopharm LLC, the largest enterprise for the production of biological plant protection products from diseases and pests.
"Lepidotsid" is produced in the form of a concentrate in dry and liquid form:
A) "Lepidotsid, P" Available in powder form, packaged in sealed packaging for agricultural production in 10 kg, 15 kg, 20 kg. and for private household plots 10g, 20g, 50g, 100g. The convenience of this form lies in the long shelf life of up to 1.5 years, which reduces bacterial activity. When preparing the working stock solution, the activity of bacteria increases, maximum activity is observed after 1-3 days.
Examples of the biological product “Lepidocid” in powder form
b) "Lepidotsid, SK" are produced in the form of a suspension concentrate, packaged for agricultural production in canisters from 5 liters. up to 20 l. and bottles of 1 liter, for personal households from 5 ml. in ampoules and 20 ml, 35 ml. in bottles. When preparing the working solution, it is recommended to add green soap or other adhesive to the composition.
V) "Lepidotsid, SK-M"- a modified version of the suspension concentrate. The manufacturer does not specify what the innovation is, perhaps in the production of Bacillus thuringiensis serotype IV.
Examples of the biological product “Lepidocid” in the form of a suspension concentrate
Processing regulations
The working solution is prepared by adding the concentrate with continuous stirring, the dose is introduced gradually, the dosage can be varied. If the solution is prepared from a dry concentrate, before spraying it is recommended to “infuse” the mother solution so that the bacterial spores start the vital activity mechanism. It is advisable to add any adhesive to the composition.
It is important not to delay the treatment, but to carry it out immediately when small caterpillars (outwardly similar to worms) are detected, before they begin to bite into the fruit.

Restrictions and security
According to the conclusion of the Research Center for Toxicology and Hygienic Regulation of Biological Products (SRC TBP) of the Ministry of Health of the Russian Federation, the biological product “Lepidocid” belongs to the 4th class of hazard (little dangerous) for humans and warm-blooded organisms (maximum safe, considering that the 5th class does not apply to agrochemical preparations assigned).
The waiting period before harvesting is only 5 days; it does not accumulate in the fruits.
The turnaround time for manual work is 5 days, and for mechanized work – 1 day.
"Lepidotsid" is safe for insects - entomophages, bees and other pollinators. For them it belongs to the 3rd hazard class. The biological product has an unpleasant odor and actually serves as a fumigant for them, providing a protective barrier to contact.
“Lepidotsid” is also absolutely safe for plants and soil, since the bacteria Bacillus thuringiensis live only in the nutrient medium of the insect’s body.
The instructions for use do not regulate special safety conditions when working with the drug, its storage, transportation or disposal.

2. Relatively low rate of impact on insects, insect death is observed no earlier than 2-3 days;
3. Acts only on younger ages (1-4 ages), does not affect adults (reproductive and migrating ages);
4. Works only against gnawing insects, not against sucking insects;
5. The working solution has an unpleasant odor;
6. Due to the nature of the application, multiple treatments are required.
All the obvious advantages of biological products appear only with their constant and regular use.
LEPIDOCID
Purpose
Lepidocide- a biological insecticidal preparation intended to protect forest, agricultural and park crops from caterpillars of lepidopteran insects, including silkworms,nun moth, moths, leaf rollers, including bunch moths, meadow moths, cabbage and turnip moths, American white butterfly, hawthorn, cutworms, moths, etc. Lepidocide is approved for use in agriculture and forestry, in household plots and in urban green spaces.
Description
Lepidocide is an insecticidal biological preparation with intestinal action. It is highly effective in controlling leaf-eating pests. The product has a selective effect due to the specific structure of the intestines of pests. The active substance is spores and microbial culture crystals ,
as well as biologically active substances - waste products of bacteria.
Mechanism of action
The insecticidal effect of the drug is based on two mechanisms.
Controversy Bacillus thuringiensis, included in the drug Lepidocide, after entering the intestine, they germinate and penetrate the intestinal wall, entering the hemolymph. In the hemolymph, bacteria actively multiply, causing septicemia and death of the insect. This occurs immediately after treatment (within 4 hours).
The second mechanism is based on the accumulation of the drug in the culture fluid Lepidocide toxins (α-, β-, δ-exotoxin) during the production process of the drug. Bacterial toxins, under the influence of alkaline intestinal digestive juices, become active, causing paralysis of the mid-intestine, and then general paralysis, which leads to the death of the insect.
The product is used at any stage of plant development. This is especially important during the flowering period during pollination by insects, also before seasonal harvesting (in areas of dense human habitation, in resort and nature conservation areas). The most valuable qualities of Lepidocide are considered to be the impossibility of pests becoming accustomed to it, the preservation of beneficial entomophages and the production of clean, environmentally friendly products. The drug does not affect the taste of products and does not accumulate in soil or plants.
Application and processing conditions
Lepidocide used when infesting pests of the order Lepidoptera(Lepidoptera).
Pests of field crops(beets, sunflowers, alfalfa, soybeans, peas): meadow moth, cutworms, moths.
