Abstract

The invention belongs to the technical field of pesticide compounding, and specifically relates to a kind of missible oil for controlling meadow moth and applications thereof. The effective components of the missible oil are high-efficient trans-cypermethrin and S-fenvalerate, wherein the weight ratio of the high-efficient trans-cypermethrin to S-fenvalerate is 10:1 to 1:10. The missible oil has an especially good control effect on meadow moth because of the synergetic effect between every component in the missible oil.
