Product performance:
1. This product is a type of crystal-producing Bacillus including many varieties. It can be used to control various pests of the order Orthoptera, Coleoptera, Diptera, Hymenoptera, especially Lepidoptera.
2. Bacillus thuringiensis can produce two major toxoids: endotoxin (ie parasporal crystals) and exotoxin (α, β, and γ exotoxin). Parasporal crystals are the main toxins.
3. In the basic gastrointestinal tract of insects, the intestine can be paralyzed within minutes, the insects stop feeding, and quickly destroy the intestinal lining, causing the vegetative cells of the bacteria to easily invade and penetrate the intestinal lining. Hemolymph, eventually insects die from starvation and sepsis.
4.Exotoxin has a slow effect, and it has obvious effects during molting and metamorphosis. These two periods are the peak periods of RNA synthesis. Exotoxin can inhibit DNA-dependent RNA polymerase.
