Abstract:

This study aims to clarify the effect of pesticide synergists (main ingredients are compound modified vegetable oil, complex sugar alcohols, non-ionic surfactant) on the physical properties of beta-cypermethrin, emamectin benzoate, nicotine·matrine, imidacloprid and chlorobenzuron, in order to explore their synergistic mechanism. The effects of pesticide synergists on the surface tension, contact angle, expanded diameter and maximum retention of the above 5 insecticides were determined. The results showed that the combination of pesticide synergists and 5 insecticides showed different improvements in physical properties. The results showed that pesticide synergists had a basic condition for enhancing the physical properties of the 5 insecticides, and the synergistic effect of their insecticidal effect needed to be verified by further bioassay.

Key words: beta-cypermethrin, emamectin benzoate, nicotine·matrine, imidacloprid, chlorobenzuron, pesticide synergists, physical properties
