Abstract

The invention discloses an uvioresistant absorber used for a pesticide preparation, and the uvioresistant absorber is isothiazole carboxamides , and accounts for 0.01-1% by mass in a pesticide preparation. The uvioresistant absorber can be added into the pesticide preparation to reduce active ingredient decomposition caused by sunlight or ultraviolet radiation in the storage, transportation, especially applying processes of light-sensitive pesticide active ingredients, and can improve the utilization rate of the pesticide active ingredients, prolong the half-life of the active components, and improve the stability of the pesticide active ingredients. By use of the uvioresistant absorber, the insecticide and germicide control effect of the pesticide preparation can be improved, the persisting pesticide efficacy is prolonged, and the pesticide dosage is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to an anti-ultraviolet absorber used in pesticide preparations. Background technique [0002] At present, after the application of pesticide preparations, the active ingredients are seriously degraded in the environment due to the influence of biological factors and abiotic factors. Among them, the photochemical degradation process is the main form of abiotic degradation of pesticides. performance has a significant impact. The ultraviolet light that can affect the environment due to natural sunlight mainly includes UV-A (wavelength range between 320-400nm) and UV-B (wavelength range between 290-320nm). The way to prevent the photolysis of photosensitive pesticides in the prior art is mainly to add UV-A ultraviolet absorbers and UV-B ultraviolet absorbers to the formulation formula, so that the pesticide preparations have a negative effect on the photolysis of light-s...
