Tiangang HS-200 - Photodecomposition of avermectin and screening of its light stabilizer
from hownet

Wu Chuan Wan , Du Xiaofeng , Wang Weizhong , Tian Xingjun
Abstract:
The photodecomposition of avermectins under sunlight and ultraviolet light was studied. It was found that avermectins were easily decomposed by light, and their photodecomposition half-life was about 3H. Using 10 different light stabilizers can inhibit the photodecomposition of avermectin to a certain extent, of which BHA has the most obvious inhibitory effect. On this basis, the inhibitory effect of different concentrations of BHA on the photodecomposition of avermectin was studied, the results showed that the inhibitory effect was related to the concentration of the stabilizer, and the greater the general treatment concentration, the stronger the effect of inhibiting the photodecomposition of avermectin.
Key words:
