Abstract

The invention discloses an insecticidal composition containing bromantraniliprole and carbamates. The insecticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is the bromantraniliprole; the active ingredient B is one of the following compounds: isoprocarb, metolcarb, indoxacarb and carbaryl; and the weight ratio of the active ingredient A to the active ingredient B is (1:70)-(50:1). The composition has an effect of synergizing various pests which endanger the agricultural production, is safe to people and livestock, and is high in environmental compatibility, the dosage of pesticides is reduced, the residual amount of the pesticides on crops is reduced, the environmental pollution is reduced, and the pests cannot produce pesticide resistance easily.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing bromotiliprole and carbamates on crop pests. Background technique [0002] Isoprocarb (isoprocarb) chemical name: o-isopropylphenylmethyl carbamate, molecular formula: C 11 h 15 NO 2 . Isoprocarb is a carbamate insecticide, which mainly inhibits acetylcholinesterase on insects, causing paralysis to death of insects. [0003] Metolcarb (metolcarb) chemical name: m-tolyl-N-methylcarbamate, molecular formula: C 9 h 11 NO 2 . Meprocarb has contact killing and fumigation effects, strong knockdown power, short duration of effect, generally only 3-4 days, and has special effects on rice planthoppers, rice leafhoppers, rice thrips, and tea leafhoppers. [0004] Indoxacarb chemical name: 7-chloro-2,3,4a,5-tetrahydro-2-[methoxycarbonyl(4-trifluoromethoxyphenyl)carbamoyl]indeno[1 ,2-e][1,3,4-]oxadiazine-4a-carboxylate methy...
