t is a phosphorothioate insecticide with contact killing, stomach poisoning and fumigation effects. The residual period on the leaves is not long, but the residual period in the soil is longer, so the control effect on underground pests is better. No phytotoxicity to most crops at recommended doses, but sensitive to tobacco.
