var. Aizawai 32000IU/mg WP

Unlike typical nerve-poison insecticides, Bacillus thuringiensis var. Aizawai acts by producing proteins (delta-endotoxin, the "toxic crystal") that reacts with the cells of the gut lining of susceptible insects. After feeding on these Bt-proteins, the digestive system becomes paralyzed and the infected insect stops feeding within hours. Bt-affected insects generally die from starvation, which can take several days. Bacillus Thuringiensis var. Aizawai is produced for vegetable, rice paddy, tea plant and forest. Out B.T. products have the features with: high efficiency, broad spectrum, safe, economic, no pollution, and no resistance from pests and protection the natural enemy of the pest, It is the first and best choice for Lepidoptera and some Coleopteran pests control.
