The invention discloses insecticidal water
emulsion containing acetylspiramycin, wherein effective ingredients are the acetylspiramycin and agricultural insecticide, the weight ratio of the acetylspiramycin to the agricultural insecticide is 1: (1-1) :5, and the weight percentage of the acetylspiramycin to the agricultural insecticide in the water
emulsion is 5-10%. Active ingredients of the agricultural insecticide are selected from one or two of
abamectin,
chlorpyrifos,
lambda-
cyhalothrin, beta-
cypermethrin and triazophos. The insecticidal water
emulsion has a good contact action on multiple
crop pests, agentia has lipotropy performance, high efficiency is achieved for adult or weak pests,
beneficial insects are not killed or damaged, pests do not generate resistance easily, and a insecticidal spectrum is wide; by means of the insecticidal water emulsion, consumption of
pesticide is reduced, the prevention and
treatment effect is improved, the current problem of pest resistance to insecticide is relieved to the maximum degree, the purpose of protecting crops is achieved, the yield can be raised, and quality can be improved.
