A kind of insecticidal composition containing pymetrozine

Abstract

The invention relates to an insecticidal combination containing pymetrozine. Imicyafos and the pymetrozine which serve as effective components are mixed; the weight ratio of the two effective components is (1-50):(55-1), and preferably the weight ratio is (5-25):(35-5). The insecticidal combination comprises 1-80 percent of the effective components by weight, preferably 5-40 percent of the effective components, and the balance being pesticidally available and acceptable auxiliary components. Wettable powder, a suspending agent, a microemulsion, an emulsion in water and a water dispersible granule can be prepared by a known method. The combination disclosed by the invention has a wide acting field and is high in insecticide efficiency; furthermore, the using amount is small; the prevention efficiency is high; the residue content is low; the lasting period is long; the environment can be protected favorably.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing pymetrozine. Background technique [0002] Imicyafos (AKD-3088) is a cyanamide heterocyclic organic compound, which is composed of asymmetric organophosphorus and cyanoimidazolidine of nicotinic insecticides, and can be used for radish, carrot, strawberry, eggplant, tomato , cucumber, melon, watermelon, sweet potato and potato and other crops, its chemical structure is: [0003] [0004] Pymetrozine, alias: pyrazinone, English name: pymetrozine, molecular formula: C 10 h 11 N 50 , chemical name: 4,5-dihydro-6-methyl-4-(3-pyridinemethyleneamino)-1,2,4-3(2H)-one, with high efficiency, low toxicity and high selectivity , friendly to the environment and other characteristics, in line with the current development direction of pesticides. Its structural formula is: [0005] [0006] Its mode of action is unique, mainly af...

AI Technical Summary

Problems solved by technology

[0007] After long-term use of pymetrozine, the resistance of pests to it increases year by year, which increases the amount of pesticides used, resulting in adverse consequences such as high toxicity, large dosage, large residues, and poor efficacy.
