Microbial Biological Pesticides With Bacillus Thuringiensis Bt

Biological Agriculture Insecticide Bacillus Thuringiensis Bt Killing Pests on Vegetable

The preparation of Bacillus thuringiensis has good control effect on some lepidopteran insect larvae, and can be used to control cabbage insect, rice bud, inchworm, pine caterpillar, tobacco worm, corn borer, cotton bollworm, rice leaf suppressant, demoiselle moth, tiger, etc. Its insecticidal principle is that the bacillus thuringiensis after pests eat, parasitism in the host intestine and to grow in the intestinal alkaline environment right, crystal toxins through the worm intestinal protease hydrolysis, the formation of toxic effect of smaller subunits, their effects on insect body in intestinal epithelial cells, causing intestinal paralysis, perforated, insect body paralysis, stop eating. Bacillus thuringiensis then enters the blood cavity and multiplies, causing septicaemia, which leads to death

Bt is the wide spectrum, high-effective bio-pesticides of stomach poison, which has excellent control effects to various pests and resistance pests. It especially has specialized killing function to lepidoptera, diptera, coleoptera pests.

Bacillus thuringiensis is suitable for a wide range of objects. Including cruciferous vegetables, nightshade vegetables, melon vegetables, tobacco, rice, corn, sorghum, soybean, peanut, sweet potato, cotton, tea tree, apple, pear, peach, jujube, Citrus, banana, mango, lychee and other crops as well as forests and grasslands.
Bacillus thuringiensis has a wide insecticidal spectrum and is mainly used to control lepidopteran pest larvae, such as cabbage caterpillars, diamondback moths, beet armyworms, Spodoptera litura, cabbage armyworms, tobacco caterpillars, corn borers, rice leaf rollers, two The larvae of various insect pests, such as the borer, pine caterpillar, tea caterpillar, tea inchworm, corn armyworm, pod borer, and Spodoptera frugiperda. preventive effect.

Dosage: depends on the target pests, spray

Matters needing attention
1. Bacillus thuringiensis can only play its full role in high temperature (above 20℃), so the application effect is best from July to September; The suitable time of application is 2-3 days earlier than that of chemical pesticide
2. It is effective to rice cnaphalocrocis medinalis, corn borer, bridge worm, pine caterpillar and tea caterpillar, but less effective to giant borer.
3. Low toxicity to bees, but highly toxic to bombyx mori and castor silkworm, should be strictly controlled, not used in sericulture areas. If mulberry leaves are stained with fungus powder, it is necessary to sterilize with 0.2% bleach powder, wash and dry before feeding
4. Do not mix with fungicides
5. Should be sealed, shaded, stored in a cool, dry place, and rodent bite

This product should be stored in a dry and cool warehouse below 25℃ to prevent exposure to sunlight and humidity. Do not mix with food, seeds, feed and grain. Don't be stressed. Keep out of the reach of children, and keep it locked. Handle with care during transportation to prevent damage.
