Problems solved by technology

Water-based and granulated preparations are rapidly replacing old formulation products such as emulsifiable concentrates and wettable powders, and gradually become the leading role in the preparation market. However, with the emergence of a large number of water-based and granulated products, especially water-based Some problems in application have been solved. Compared with emulsifiable concentrate preparations, the application effect of some products has a certain gap. How to solve this problem is very critical for the green transformation of pesticide formulations in the future.

Abstract

The invention discloses a pymetrozine suspension preparation composite and a production method thereof. The composite is constituted by the following components according to weight percent: 5-50% of pymetrozine, 1-3% of wetting agent, 2-5% of dispersing agent, 5-15% of emulsifying agent, and the remainder complemented by solvent. The pymetrozine suspension preparation composite of the invention takes vegetable oil as the carrier, has good affinity towards a target, is durable to rain and water rinsing, and has the advantages of evaporation resistance, storage endurance, strong permeability andthe like, thus enhancing bioactivity of the bulk drug, prolonging the contact time between the bulk drug and the target insects, and improving drug efficacy.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a pymetrozine preparation and a preparation method thereof. Background technique [0002] Pymetrozine English name: pymetrozine, molecular formula: C10H11N50, chemical name: 4,5-dihydro-6-methyl-4-(3-pyridinemethyleneamino)-1,2,4-3(2H)- ketone. [0003] This new high-efficiency insecticide is a pyridine heterocyclic insecticide with high efficiency, low toxicity and environmental friendliness. The insecticide has a unique mode of action, no knock-down activity, and no direct toxicity to insects, but once the insects come into contact with the agent, they stop feeding immediately. Because of its high selectivity, low toxicity to mammals, and safety to birds, fish, and non-target arthropods, it shows good development prospects in integrated control. [0004] At present, the preparations of pymetrozine mainly include wettable powder, water dispersible gr...
