Abstract

A special synergist for pesticide spraying, which contains the following raw materials in mass percentage: 1-60% of surfactant A, 0.01-5% of surfactant B, 0.1-10% of thickener, and the remaining components are water; The surfactant A is selected from propylene oxide condensate, polyoxyethylene-polyoxypropylene copolymer, polyether polyol, dioctyl sulfosuccinate sodium salt and di-2-ethylhexyl sulfosuccinate A mixture of two or more of sodium salt, alkylbenzene sulfonate, fatty acid polyoxyethylene ester, and fatty alcohol polyoxyethylene ether; the surfactant B is sodium subtilisin. The invention can significantly reduce the surface tension of the liquid medicine, improve the adhesion and wetting and penetration performance of the mist on the target, reduce the floating and bouncing of the mist, improve the utilization rate of the liquid medicine, and is safe, efficient and widely applicable.

Description

technical field [0001] The invention relates to the field of high-efficiency dispersion of pesticides, in particular to a special synergist for pesticide spraying and a preparation method thereof. Background technique [0002] At present, the control of crop diseases, insect pests and weeds in my country is still dominated by spray control, but in the process of control, only 20% to 30% of the sprayed pesticides can be deposited on the target, and 70% to 80% are lost or drifted into the soil and water. It has caused serious pollution to farmland ecology and even the living environment of human beings. In order to protect the ecological environment and ensure the quality and safety of agricultural products, improving the utilization rate of pesticides and reducing the amount of pesticides used have become the focus and focus of current research in the field of plant protection. In the process of spray application, the addition of good spray auxiliaries can effectively reduce ...
