such as cotton bollworm, Chinese cabbage insect, poisonous moth, pine caterpillar, corn borer, sorghum borer, etc. Mechanism of action When the insect nibbleth the spore crystals and spores, the spore crystals dissolve in the intestinal alkaline environment of the insect, releasing the toxin which has a strong killing effect on Lepidoptera larvae. This toxin causes the midgut paralysis of the larvae, showing poisoning symptoms, and generally does no harm to the crops. After a
period of onset, the intestinal wall of the insect is damaged, the toxin enters the blood, causing septicemia, and at the sametime the spores multiply rapidly in the digestive tract, accelerating the death of the insect.The effect of exotoxin is slow and obvious duringmolting and metamorphosis The effect of this drug is slow, and the effect can only be seen in about 2 days after the pest is fed, and the effective period is about 1 day, so it should be used 2 ~ 3 days earlier than conventional chemical agents, and the effect is better in the early age of the pest. advantage
1. Strong selectivity and no harm to natural enemies 2. Not affect the activities of soil microorganisms 3. No residual poison, the production of products can be safe to eat.
