The search for effective methods of combating harmful insects is an urgent problem for gardeners. Lepidocid is a popular remedy against various types of pests. Instructions for use Lepidocide contains detailed information about the mechanism of action and the rules for using the insecticide.
Description of the preparation Lepidocide
The agent is an insecticide of biological origin. The substance is intended to protect crops from insect pests. Due to the specificity of the components, it has a selective effect.
Composition of Lepidocide
The main active ingredient is the spores of microbes Bacillus thuringiensis var. Kurstaki, as well as their metabolic products. It is a type of Gram-positive soil bacteria that produces endotoxins that exhibit insecticidal properties.
Manufacturer and dosage forms of Lepidocide
Biological raw materials for the drug are produced with the help of OOO PO Sibbiopharm. This is a well-known manufacturer of active substances used for agricultural purposes. The raw materials produced by this enterprise are used by other companies to produce various types of Lepidocide.
Detailed information about the tool:
The drug is produced in several forms. The most common option is a powder for making a liquid suspension, which is treated with affected plants. Lepidocid is produced in packages of 1 kg. The composition of the powder includes a large number of active spores. However, if used improperly, they do not provoke the growth of bacteria, as a result of which the effectiveness of the insecticide decreases.
Pesticide used to control caterpillars of harmful insects
The second form of Lepidocide is a suspension concentrate (SC). This is an insecticide in liquid form, available in containers from 0,5 liters. It is usually used for mass pest infestations. There is also a modified suspension concentrate, which contains bacteria of a different serotype.
The mechanism of influence on pests
The main characteristics of Lepidocide are high selective efficiency and safety for plants. The tool belongs to the category of intestinal insecticides.
The effect occurs when the active ingredients of Lepidocide penetrate the digestive system of the insect. Endotoxins, which are produced by bacteria, are activated inside the intestine and destroy it. This leads to the fact that the pests lose their ability to eat and subsequently die.
The tool is effective against the following types of insects:
- leaflets;
- silkworm;
- meadow moths;
- moths;
- whites;
- fruit moth;
- cabbage and cotton scoops;
- fireworks;
- apple codling moths;
- American butterfly.
The drug, due to the rich smell, is a strong repellant for insects (repellent)
The action of the drug begins 4-5 hours after the treatment of the plant. Mass death of insects occurs in 3-7 days.
Pros and cons of the drug Lepidocid
Biopreparation has many advantages. In addition to a wide spectrum of action and a high level of effectiveness, this insecticide is completely safe for the human body.
Other benefits include:
- The active ingredients are safe for bees and pollinating insects.
- The agent does not have a harmful effect on plant cells.
- The drug does not affect the composition of the soil, since its main habitat is the intestines of insects.
- Active bacteria and spores do not accumulate in fruits.
- Pests do not show resistance to the insecticide, that is, they are not able to adapt to its action.

“Lepidocid” is safe for bees and entomophage insects
Among them:
- The drugs only work when they enter the intestines.
- The active substances do not destroy the pests, but interfere with their nutrition, which leads to death only after a few days.
- The migratory and breeding generation of insects may not be sensitive to the drug.
- The tool is ineffective against certain types of beetles and dipterans.
- The insecticide only works on leaf-eating insects.
- The drug has a sharp unpleasant odor.
- Treatment with Lepidocide must be carried out repeatedly to prevent the reappearance of pests.
These shortcomings indicate that the drug is not universal. Therefore, to achieve the desired effect, the use of an insecticide must be in accordance with the rules.
Instructions for use Lepidocide for plants
The method of use depends on which crop is affected by pests. Also, the application is affected by the variety of “Lepidocide”.
The plant should be treated with such a remedy in case of mass damage by leaf-eating insects, especially caterpillars. The powder or concentrate is dissolved in water.
The treatment preparation consists of a concentrate, water and an adhesive agent. The function of the latter can be performed by a soapy liquid or a small amount of detergent.
Preparation of insecticide:
- Calculate the dose of the drug for the treatment of a particular type of crop.
- Dilute the required amount of powder in 0,5 liters of warm water.

Caterpillars after treatment with the drug die for 2-3 days
This preparation method is used for both powder and Lepidocide concentrate. The treatment of affected plants should be carried out in the morning, when the dew dries. Foliage must be dry. If rain is forecast, the procedure is recommended to be rescheduled.
The use of Lepidocide for vegetable crops
The insecticide is intended for repeated processing during the growing season. The period between each procedure is 5 days. To get rid of pests of vegetables, 2-3 treatments are enough.
Lepidocid is used to protect such crops:
- potatoes;
- cabbage;
- beet;
- carrot;
- tomatoes;
- eggplants;
- pepper.
The agent does not accumulate in plants and fruits
The most common vegetable pests are potato and cabbage moths, Colorado potato beetle, shovel, meadow moth and moth. Processing is carried out for each generation of insects. Detailed instructions for the use of Lepidocide against potato moths and other types of pests are included with the preparation. The volume of the working solution is from 200 to 400 liters per 1 ha of land.
Treatment of fruit and berry crops with Lepidocide
