Research and Exploitation of Chorpyriphos Pesticide Microemulsion

摘要

Pesticide formulation science is significant to deal with formulation development, production and storage as well as the interaction of the pesticide with plants, insects, mammals, soil, air and water. Aqueous pesticide microemulsion has become one of the most potential pesticide formulation instead of the conventional pesticide formulation in recent years. Very few works has studied the methodology of pesticide microemulsion preparation with environment-friendly compound.The green environment-friendly chorpyriphos pesticide microemulsion was successfully obtained through the further trials of screening of heat storage and cold storage experiments and the examination of dissociation rate. The optimized chorpyriphos microemulsion formulation is composed of chlorpyrifos (2.366%), ethyl acetate (1.001%), agricultural emulsifier 600(5.714%), natural carboxylate (2.857%), glycol (33.972%), ethanol (14.571%), and water (39.519%).
