The search for effective methods of combating harmful insects is an urgent problem for gardeners. Lepidocide is a popular remedy against various types of pests. The instructions for use of Lepidocide contain detailed information about the mechanism of action and the rules for using the insecticide.
Description of the drug Lepidocide
The tool is an insecticide of biological origin. The substance is designed 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 the microbes Bacillus thuringiensis var. Kurstaki, as well as their waste products. It is a type of gram-positive soil bacteria that produces endotoxins that exhibit insecticidal properties.
Manufacturer and release forms of Lepidocide
Biological raw materials for the drug are made with the help of OOO PO Sibbiopharm. It is a well-known Russian manufacturer of active substances used for agrotechnical purposes. The raw materials produced by this enterprise are used by other companies for the production of various types of "Lepidocide".
Details of the tool:
The drug is produced in several forms. The most common option is a powder for making a liquid suspension, which is used to treat affected plants. "Lepidocide" is produced in packages from 1 kg. The composition of the powder contains a large number of active spores. However, if used incorrectly, they do not provoke an increase in the number of bacteria, as a result of which the effectiveness of the insecticide decreases.
The pesticide is used to control the caterpillars of harmful insects
The second form of Lepidocide is suspension concentrate (SC). This is an insecticide in liquid form, available in containers of 0.5 liters. As a rule, it is used for mass invasions of pests. There is also a modified suspension concentrate that contains bacteria of a different serotype.
The mechanism of action on pests
The main characteristics of Lepidocide are high selective efficacy and safety for plants. The tool belongs to the category of intestinal insecticides.
The effect occurs when the active ingredients of "Lepidocide" penetrate the insect's digestive system. Endotoxins, which are produced by bacteria, are activated inside the intestine and destroy it. This leads to the fact that pests lose their ability to feed and subsequently die.
The agent is effective against the following types of insects:
- leaf rollers;
- silkworm;
- meadow moths;
- moths;
- whites;
- fruit moth;
- cabbage and cotton scoops;
- moths;
- apple moths;
- American butterfly.
Due to its rich odor, the drug is a strong insect repellent (repellant)
The action of the drug begins 4-5 hours after the treatment of the plant.Mass death of insects occurs in 3-7 days.
