Bacillus thuringiensis, or Bt, is a group of crystallogenic bacillus that includes many variants. The bacteria can produce two major toxins, namely endotoxin (companion cell crystal) and exotoxin, which stop the pests from feeding, and finally the pests die from starvation and poisoning.
The effect of exotoxin is slow and obvious during molting 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.
