Plant-derived pesticide for preventing and controlling root bug

Abstract

The invention discloses a plant-derived pesticide for preventing and controlling root bug. 1-2% by volume of trehalose, 0.1-0.5% by volume of chitosan and the balance traditional Chinese medicine components are evenly mixed to obtain a mixed culture medium containing traditional Chinese medicine activity, compound microbial strains are inoculated into the mixed culture medium containing traditional Chinese medicine activity for fermentation culture until the concentration of microorganisms reaches to be 3 billion strains / ml, and the plant-derived pesticide for preventing and controlling root bug is obtained. The traditional Chinese medicine components comprise: sophora alopecuroides, lightyellow sophora root, crofton weed, turmeric, cyrtomium fortune rhizome, giant knotweed rhizome, bark of Chinese corktree, falsehellebore root and rhizome, common cnidium fruit and clove. According to the pesticide, problems that root bug cannot be effectively suppressed and the food safety is caused by applying chemical pesticides in the prior art are solved, root bug can be effectively prevented, the pesticide is environment-friendly and pollution-free, and no food safety problem can be brought.

Description
