Application in Pesticide Industry

XIA Chun-hua,YANG Zhong-ming,ZHU Bo-rong,YE Yong

(Zhejiang Zhongke PlantTech.Co.Lid,Hangzhgou 310008,China)

 

Abstract: The application of tea saponin in the field of pesticide industry was comprehensively summed up in this paper, and presented the possible pathway to apply tea saponin.The functional mechanism of tea saponin was discussed including surface tension, contact angle and wettability ,they showed tea saponin being a kind of natural surface active agent suitable for agricultural and industrial application. The facts proved that tea saponin could be saponin could be used as a wattable formulation of wattable powered pesticide, could make such items as wettability,  pH, suspension rate etc reach or exceed the national standard. Tea saponin could be used as synergist, spreader in emulsion pesticide. It could be used in the soluble powder herbicides or liquid herbicides to improve the effectiveness, and better than similar products in abroad. Tea saponin ,as a biological pesticide ,it could also be used as insecticide, fungicide, snarlcide, etc.

Key words: Tea saponin; Pesticide industry ; pesticide auxiliary; Biological pesticide
