Abstract

The invention specifically relates to a composition containing spinetoram and application thereof, belonging to the technical field of complex formulation of pesticides. Effective components of the composition are high-efficiency trans-cypermethrin and spinetoram, and a weight ratio of spinetoram to high-efficiency trans-cypermethrin is 1: 1 to 10: 1. The composition effectively inhibits generation of insect resistance and utmostly alleviates the problem of drug resistance of insects at present, so the application amounts of pesticides are reduced, influence on the environment is abated, and the composition is applicable to nuisanceless crops.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a composition containing spinosad and its application. Background technique [0002] Beta-cypermethrin [0003] English name: theta-cypermethrin [0004] Molecular formula: C 22 h 19 C I2 NO 3 [0005] Chemical name: (S)a-cyano-3-phenoxybenzyl(1R,3S)-3-(2,2-dichlorodienyl)-2,2-dimethylcyclopropanecarboxylate and (R)-a-cyano-3-phenoxybenzyl(1S,3R)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate [0006] Chemical class: Pyrethroids [0007] Physical and chemical properties: The appearance is white or light yellow crystalline powder, without visible foreign impurities.
