Abstract
The present invention relates to an Africa mountain soya bean pesticide and a preparation method thereof. The preparation method has the step that the stems and the leaves of Africa mountain soya beans are made into wettable powder or an emulsifiable solution or a microemulsion through certain working process. The pesticide of the present invention has good pest killing effect, and is also safe to environment, people, livestock, natural enemies of pests and other beneficial organisms; the pests are difficult to generate pesticide resistance to the Africa mountain soya bean pesticide. The pesticide has the advantages of simple manufacturing technique and low cost; besides, the pesticide is suitable for popularization and application.
Description
The invention belongs to the pesticide processing field, specifically a kind of Africa mountain soya bean pesticide and manufacture method thereof.
