Video: Lepidocide Is An Effective Drug Against Leaf-gnawing Pests
It often happens that chemical insecticides, especially those that have been on the market for a long time, cease to act on pests due to the development of resistance (resistance) to the active substance, and then biological preparations can come to the rescue, which, by the way, have a number of advantages. In this article you will find out how Lepidocide will protect vegetable, berry, ornamental and fruit crops from leaf-eating pests.
Lepidocide protects plants from moth, silkworm, nun, leafworm, scoop, meadow moth, white butterfly, moth, apple moth, moth and other pests.
The drug kills the pest, getting inside its body, while it does not accumulate in plants at all and is safe for people, animals and bees.
By the way, it is Lepidocide that helps to preserve relict and young boxwood seedlings on the Black Sea coast of the Krasnodar Territory from the boxwood moth, despite the fact that drugs based on pyrethroids, phosphogenic insecticides and neonicotinoids are inferior to it in efficiency, including due to the development of pest resistance to drugs.
Benefits of Lepidocide:
- Does not accumulate in plants and fruits and guarantees production of products that are safe for health.
- Does not possess phytotoxicity. The plant will not get burned or leaf fall, as can happen when using chemical insecticides.
- It is applied at any stage of plant development. The waiting period is five days, which allows processing shortly before harvest.
- Compatible in tank mixes with chemical pesticides and biological agents.
- It will help to solve the problem of resistance of populations of harmful insects to chemical pesticides.
- If the consumption rate is observed, the drug is safe for humans, warm-blooded animals, fish, aquatic organisms, bees and entomophages. According to the conclusion of the Research Center of Toxicology and Hygienic Regulation of Biological Products (SRC TBP) of the Ministry of Health of the Russian Federation, Lepidocide (P, SK and SK-M) belongs to the 4th hazard class
Active ingredient: Bacillus thuringiensis, var. kurstaki
Effects on harmful organisms
The death of the pest, depending on the dose of the drug, can occur from 1 to 4 days, but it is important that immediately after treatment, the caterpillars already have such damage to the intestinal tract, which makes it impossible for them to feed.
The highest effectiveness of the drug is shown against young larvae at an air temperature of 18-30 ° C. Mass death of insects occurs on the 2-5th day. The drugs also have an effect on subsequent generations of insects - plant pests: ugly pupae appear in the populations, and the butterflies that emerge from them give offspring that are incapable of prolonging the genus, the sex ratio also changes, the fertility of females decreases. Preparations based on Bacillus thuringiensis, var. kurstaki retain their activity on treated plants for 8-10 days. Resistance to drugs based on Bacillus thuringiensis, var. kurstaki is not observed.
Method of using Lepidocide
The solution is prepared on the day of spraying. It is important to strictly adhere to all the rules that are prescribed in the instructions attached to the drug. The prepared mixture must be used within 24 hours. Shake well before use.
Preparing a solution is very simple. First, according to the table, the required rate of Lepidocide is determined, which is diluted in clean water with a temperature of 20 degrees Celsius. A ready-made solution is used in dry weather, at an ambient temperature not exceeding 35 degrees Celsius.
Tip: the maximum effect will be achieved if plants are treated in the early stages, when the caterpillars of leaf-eating pests are just emerging.
Re-spraying of plants should be carried out after 7-8 days. This is done only when the pest continues to develop. The last processing is allowed to be carried out no later than 5 days before the harvest.
Despite the fact that the insecticide practically does not harm people for safety reasons, the treatment should be carried out in special protective clothing that covers the skin, a gauze bandage, glasses and gloves.
Feedback from growers and our own experience indicate that the insecticide in question has a long-lasting effect and does not require a lot of free time to process plants.
Thus, we can recommend the drug Lepidocide for the protection of flowers, vegetables, fruit and berry and coniferous crops.
