Water-based plant-source pesticide with diosgenin and method for preparing water-based plant-source pesticide

Abstract

The invention relates to a water-based botanical pesticide containing diosgenin and a preparation method. The raw material components and their weight percentages are composed as follows: 1-40% of diosgenin, 1-10% of wetting and dispersing agent, and 0.1% of antifreeze agent. ~8%, thickener 0.1~2%, preservative 0.1~2%, defoamer 0.01~0.05%, and the rest is water. The botanical pesticide of the invention not only satisfies the enhanced effect of preventing and controlling bacterial angular spot disease of vegetables, but also enhances the resistance of crops, promotes the growth of crops, and achieves the purpose of increasing production and income.

Description

technical field [0001] The invention relates to a water-based plant source pesticide containing diosgenin and a preparation method thereof, belonging to the technical field of pesticides.
