Abstract

A natural sterilization insecticide utilizes sumac leaves or extracts thereof as a sterilization insecticide; the sterilization insecticide includes the sumac leaves or the extracts thereof. The leaves of sumac trees or the extracts thereof have the efficacies of inhibiting microbial breeding, and effectively killing pathogenic bacteria and injurious insects. The natural sterilization insecticide has the advantages of simple preparation, good effect of killing the pathogenic bacteria and injurious insects, and broad market application prospect. The invention relates to the sumac leaves or the extracts thereof for killing the pathogenic bacteria and injurious insects and preferably for plant pesticides and fungicides.

Description

technical field [0001] The invention relates to the fields of agricultural planting and plant chemical industry, in particular to a natural fungicide and insecticide. Background technique [0002] Sumac refers to a class of plants belonging to the genus Toxico-dendron in the Anacardiaceae family. It belongs to the subtropical zone. It is an ancient relic tree species of the Cenozoic and Tertiary periods and is an important economic tree species in my country. There are more than 20 species of lacquer trees, mainly distributed in eastern Asia and North America to Central America, and also distributed in India, Korea, and Japan. There are 15 species of sumac in my country, which are distributed in various provinces and regions in southern China. The distribution in Yunnan is very wide. The characteristic of Yunnan lacquer is that there are many types from small trees less than 8 meters to large trees with a height of more than 18 meters. The number of leaflets of odd-numbere...
