Description
Technical field
The present invention relates to the field of pesticides for agricultural insect pests control, particularly a kind of efficient pesticides containing cyhalothrin, MTI-446 and benzoyl urea.
Background technology
Insecticide residues and the toxicity problem to animal in agricultural product are the focuses that people pay close attention to always.
