The invention discloses novel efficient insecticide composition and an application thereof and relates to the technical field of
pesticide compounding. The insecticide composition contains an effective ingredient A and an effective ingredient B, wherein the effective ingredient A is
triflumezopyrim, the effective ingredient B is phenylpyrazole insecticide
fipronil or
butene-
fipronil, and the weight ratio of the effective ingredient A to the effective ingredient B is (1:60)-(40:1), preferably, (1:30)-(20:1). The compound agent adopts a reasonable ratio, has a remarkable synergistic effect and particularly, has excellent effects on piercing-sucking pests such as aphids, rice
planthopper, scale insects,
flea, lice and the like, the application quantity of single agents can be effectively reduced, the
insecticide resistance is delayed, environment
pollution is reduced, the safety for human beings and
livestock is enhanced, and the insecticide composition has remarkable application and promotion value.
