The invention relates to compound insecticide containing d-trans-
prallethrin chloride, which comprises, in weight percentage, 1-10% of lethal
pyrethroid compound shown in a formula (A), 0.1-2% of d-trans-
prallethrin chloride, 3-20% of emulsifier, 5-25% of cosolvent, 1-10% of antifreezing agent, 0.1-0.5% of defoaming agent, and the balance of water. The compound insecticidal preparation is simple in production process and safe in use, consumption of
organic solvent is reduced, environmental
pollution is reduced, the rate of downing sanitary
insect pests such as mosquitoes, flies, cockroaches and the like can be increased, and fine
lethality rate is achieved. In addition, the compound insecticide has evident synergetic effect on controlling the sanitary
insect pests, application amount of insecticides can be reduced, cost can be reduced, and occurrence of
drug resistance of the sanitary
insect pests can be delayed.
