The model of function:
Stomach toxicity, contacted death (chitin synthesis inhibitor)
Toxicity:
Acute oral ld50 > 8500mg/kg acute percutaneous ld50:> 1000mg/kg
Characteristics:
The mechanism of it is the inhibition of chitin synthesis, impeding the normal insect molting. As results, the eggs hatching, the larvae molting and pupal developmental appear deformity, adult eclosion is blocked, and tis product with high efficacy, the role of slow for a variety of lepidoptera pests as well as the orthoptera, coleoptera, hymenoptera, diptera, such as high activity, but aphids, leafhopper, planthopper invalidá
