Abstract

The invention discloses a dry emamectin benzoate suspending agent for preventing flying and a preparation method of the suspending agent, and belongs to the field of pesticide application. The dry emamectin benzoate suspending agent comprises, in weight percentage, 5%-40% of emamectin benzoate technical materials, 2%-10% of anionic dispersing agents, 1%-10% of solid wetting agents, 10%-20% of silicic acid metal composite salt, 10%-30% of biological extracts and the rest nano-mesoporous materials. The dry emamectin benzoate suspending agent has the advantages of good water entry dispersion and suspendability, difficulty in precipitation and separation, easiness in disintegration and evaporation and drifting resistance.

Description

technical field [0001] The invention relates to the field of pesticide application, in particular to a dry suspension concentrate of emamectin benzoate used for fly control and a preparation method thereof. Background technique [0002] Generally, pesticides need to be mechanically sprayed onto the target. With the transfer of land and the transfer of rural labor force, aerial plant protection has emerged, that is, the use of manned aircraft or drones for pesticide application. Aviation plant protection has the advantages of strong adaptability, safety and efficiency, and water saving. However, since the flight height of the aircraft is generally 2-8m, the fog droplets are easily affected by temperature, humidity, wind direction, and wind speed during the falling process. In the process of falling, it is easy to drift and evaporate. The chemical liquid of aviation spray is generally 0.5L-1.0L per mu, and the concentration of chemical liquid is higher than that of conventio...
