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...
