Abstract

The invention discloses a preparation method for a biological pesticide synergist containing saponins, belonging to the technical field of pesticides. The pesticide synergist is composed of silicon iodine fluoride, a benzenesulfonic acid emulsifier, a benzene solvent, an infiltration solvent, an organosilicon surfactant, saponins and an aqueous solution of salt. The preparation method comprises the following steps: preparing the saponins for subsequent usage; adding silicon iodine fluoride and the benzene solvent into the saponins so as to obtain a saponin mixture; successively adding the saponin mixture, the infiltration solvent and the organosilicon surfactant into a reaction vessel and carrying out uniform mixing under stirring; adding the aqueous solution of salt, carrying out uniform mixing under stirring and then carrying out heating and mixing; and carrying out cooling, adding the benzenesulfonic acid emulsifier and carrying out stirring to allow the saponins to be completely dissolved so as to obtain the pesticide synergist. The pesticide synergist provided by the invention is higher in safety to plants, reinforces infiltration, promotes absorption, can enhance the adhesion of pesticide liquid, has stable pesticide effect and no phytotoxicity, saves water for pesticide application during sprinkling of pesticides and reduces waste and pesticide residues.

Description

technical field [0001] The invention relates to a preparation method of a pesticide synergist, in particular to a preparation method of a biological pesticide synergist containing plant saponin, and belongs to the technical field of pesticides. Background technique [0002] Pesticide adjuvants generally have no biological activity in the processing and application of pesticide formulations, but they are indispensable additives in the formulation or application of pesticides. Each pesticide adjuvant has specific functions, and some act as diluents. Some can help the original drug to disperse evenly in the preparation, some can prevent the particle from agglomerating, some can increase the wettability, adhesion or permeability of the particle, and some can prevent the active ingredient from collapsing. Decomposition, some can increase the safety of pesticide application, etc. In short, the function of pesticide adjuvants is nothing more than improving the physical or chemical ...
