Insecticidal composition

Abstract

The invention relates to an insecticidal composition which comprises two active components including cyhalodiamide and chlorfenapyr. The insecticidal composition has obvious synergism for controlling rice-stem borer, and not only is capable of improving the controlling effect, but also is capable of reducing the dosage, and delaying the drug resistance, wherein the lasting period is prolonged.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition of chlorfenapyr and cyantraniliprole. Background technique [0002] Chlorfenapyr (Chlorfenapyr) is an arylpyrrole insecticide and acaricide developed by American Cyanoamide Company in the late 1980s. Its chemical name is 4-bromo-2-(p-chlorophenyl)-1-b Oxymethyl-5-(trifluoromethyl)pyrrole-3-carbonitrile. The Chinese common name is chlorfenapyr. Chlorfenapyr is a novel insecticide with a unique mechanism of action, which was successfully developed through the modification of the chemical structure of natural antibiotics. Used to control agricultural pests such as diamondback moth, Spodoptera litura, Pieris rapae, and cabbage aphid, especially pests and pests that have developed resistance to carbamate, organophosphorus, and pyrethroid pesticides, such as diamondback moth, Spodoptera litura, etc. have special effects. [0003] Cyantraniliprole (ZJ4042) is a ...

If it is not controlled in time, there will often be many dead seedlings in the field. Some fields have not been prevented and treated with the stem borer during the seedling field period. Now the proportion of dead seedlings in the field is as high as 30%, and the proportion of dead seedlings in some fields exceeds 50%, causing serious damage. Loss
