Microbial insecticide containing Metarhizium having traditional Chinese medicine activity

Abstract

The invention discloses a microbial insecticide containing Metarhizium having traditional Chinese medicine activity. According to the present invention, 0.2-0.5% by volume of chitosan is added to a culture medium having traditional Chinese medicine activity, Metarhizium is inoculated into the obtained culture medium according to a volume ratio of 4-8%, and solid fermentation is performed until theconcentration of microorganism reaches 4.0 billion strain / g so as to prepare the microbial insecticide containing Metarhizium having traditional Chinese medicine activity, wherein the culture mediumhaving traditional Chinese medicine activity is prepared by uniformly mixing milkvetch root, salvia miltiorrhiza, fructus ligustri lucidi, acanthopanax senticosus, licorice root, artemisia carvifolia,eucommia ulmoides, viscum coloratum, stemona japonica, sophora flavescens ait and azadirachta indica; and the obtained microbial insecticide can solve the problems of less number of microorganisms, low activity and the like of the microbial insecticide in the prior art, and can increase the number of microorganisms and improve the activity of microorganisms so as to provide the improved insecticidal effect.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a microbial insecticide containing traditional Chinese medicine activity Metarhizium anisopliae. Background technique [0002] At present, the insecticides widely used by people are all chemical insecticides. The long-term use of chemical insecticides not only makes pests easy to develop resistance, but also its components seriously threaten people's health. [0003] In the prior art, people began to develop microbial insecticides; microbial insecticides achieve the purpose of eliminating pests from the perspective of the biological chain, and have many advantages such as not causing pests to develop drug resistance and being harmful to the human body. However, the number of strains with insecticidal ability in the existing microbial insecticides is limited, and the activity is not high, so the insecticidal effect is not very ideal. Contents of the invention [0004] In view of thi...

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to propose a kind of microbial insecticide containing active metarhizium anisopliae, to solve the problems such as less microbial quantity and low activity in microbial insecticides in the prior art, thereby increasing the microbial insecticidal activity. increase the number of microorganisms in the pesticide, improve the activity of microorganisms, and then improve the insecticidal effect of microbial pesticides
