Ochrobactrum and biological agent thereof, preparation method and application

Abstract

The invention discloses ochrobactrum and a biological agent thereof, a preparation method and application. The ochrobactrum is ochrobactrum intermedi. The biological agent with the ochrobactrum as an active ingredient is prepared by conducting test tube culture and liquid fermentation culture on the ochrobactrum intermedi. The preparing method of the biological agent with the ochrobactrum as the active ingredient comprises the steps of test tube culture and liquid fermentation culture. The application refers to the application of the biological agent with the ochrobactrum as the active ingredient in repairing polluted soil with thiophanate methyl residues and in degrading and removing the thiophanate methyl residues in crops. The thiophanate methyl residues degrading bacteria prepared through fermentation of strains TP206 can be widely used for eliminating thiophanate methyl residue pollution in the soil, can also be directly sprayed to the surface of the soil or surfaces of the crops in agricultural production, can effectively degrade and remove the thiophanate methyl residues and are convenient to use and low in cost.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a pale bacillus and its biological preparation, preparation method and application. Background technique [0002] Pesticides The prevention and control of pests and diseases in modern agricultural production is essential, but at the same time, with the extensive use of pesticides, it also causes artificial pollution to the environment, resulting in the generation of pesticide residues in agricultural products, which directly threatens people's health. my country has put forward the "Pesticide Zero Growth Plan", the purpose is to reduce the impact of pesticides on the environment and people. In terms of reducing pesticide residues, in addition to screening high-efficiency and low-residue pesticides, scientific application methods, pesticide substitution and other technologies, biodegradation is also one of the effective technologies. Since the 1960s, American scienti...

AI Technical Summary

Problems solved by technology

Due to its stable chemical properties, the degradation half-life in the soil is long, and it can remain in the use site for a long time, which is easy to cause cumulative effects. Excessive use often causes pesticide residues in agricultural products

However, there are few research reports on the biodegradation of thiophanate-methyl residues in the academic circles, and there is no thiophanate-methyl degrader product that can be used on a large scale in the market
