Problems solved by technology

[0015] Tetramethrin has a rapid knockdown effect on mosquitoes, flies and other hygienic pests, but its lethality is poor and there is a recovery phenomenon, so it should be used in combination with other insecticidal agents
[0016] However, its effect is also very single, and the risk of resistance after large-scale application is also very high

Abstract

The invention belongs to the technical field of pesticide compounding, and specifically relates to water dispersible granules containing phthalthrin and application. The composition comprises the active components of theta-cypermethrin and phthalthrin, wherein the weight ratio of theta-cypermethrin to phthalthrin is 1:1-1:10. The water dispersible granules help to furthest alleviate the present insect drug-resistance problem, the usage amount of the pesticide is reduced, the influence on environment is alleviated, and the water dispersible granules is accord with the trend of green and environment protection in future social. The composition provided by the invention achieves extremely excellent crop protection effect.
