Plant-derived pesticide for preventing and controlling grubs

Abstract

The invention discloses a plant-derived pesticide for preventing and controlling grubs. 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 grubs isobtained. 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 grubs cannot be effectively suppressed and the food safety is caused by applying chemical pesticides in the prior art are solved, grubs can be effectively prevented, the pesticide is environment-friendly and pollution-free, and no food safety problem can be brought.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a botanical pesticide for preventing and controlling grubs. Background technique [0002] Grubs have always been one of the main reasons why crops cannot grow normally. In the prior art, insecticide is usually carried out by applying chemical pesticides in the soil. However, this approach cannot completely eliminate the grubs.

At the same time, this practice has also brought food safety problems, which seriously threaten the food safety of consumers. Contents of the invention [0003] In view of this, the object of the present invention is to propose a botanical pesticide for preventing and controlling grubs, so as to solve the problem that grubs cannot be effectively contained in the prior art and the food safety problems caused by applying chemical pesticides, t...
