Abstract

The invention discloses an insecticide composition containing chlorine chlorfenapyr and pirimicarb as active ingredients, wherein the weight ratio of the active ingredient chlorine chlorfenapyr to the active ingredient pirimicarb is (1-30):(1-30), and the total weight of the active ingredients is 1-60% in the total weight of the composition. The dosage form of the composition includes wettable powder, water dispersible granule, a suspending agent, emulsion in water and a micro-capsule suspending agent. The composition has double function mechanisms of chlorfenapyr and pirimicarb, and the occurrence of drug resistance of injurious insects is delayed and overcome. The synergism is remarkable, the dosage is reduced, the cost is reduced and the insecticidal spectrum is increased. The composition can not only be used for preventing and treating plutella xylostella, prodenia litura, rice planthopper, cotton bollworm, rice leaf folder and other injurious insects, but also can prevent and treat aphid and the like on vegetables, tobaccos and grain crops. The application range is enlarged, the composition is suitable for prevention and treatment of a plurality of lepidoptera, homoptera and dipteral injurious insects of fruit trees, vegetables, gains, tobaccos and the like.

Description

Technical field [0001] The invention relates to an insecticidal composition in which chlorfenapyr and aphiprocarb are effective ingredients. Background technique [0002] Chlorfenapyr, the chemical name is 4-bromo-2-(4-chlorophenyl)-1-[(2-chloroethoxy)methyl]-5-trifluoromethylpyrrole-3-carbonitrile, It is a new pyrrole heterocyclic compound with obvious insecticidal activity designed and synthesized by Hunan Research Institute of Chemical Industry. [0003] Its structural formula is: [0004] [0005] Chlorantranil is an analogue of the new insecticide chlorfenapyr. Its mechanism of action is to block the process of oxidative phosphorylation by interfering with the electrochemical gradient in the mitochondria. It has excellent contact, gastric toxic activity and comprehensive toxic effect, low toxicity, good safety, and no cross-resistance. It mainly controls plutella xylostella, Spodoptera litura, rice planthopper, cotton bollworm, rice leaf roller and other pests. However, it h...
