Microbial herbicide for aquatic plant

Abstract

The invention provides a microbial herbicide for aquatic plant. A bacterial strain is prepared from diphtheria bacillus, curvularia lunata, streptomyces scabies and lactobacillus plantarum.

Description

technical field [0001] The invention relates to a microbial herbicide for aquatic plants containing microorganisms and a preparation method thereof. Specifically, it relates to a microbial organic pesticide produced by effective compounding of different strains through synergistic effects, which belongs to agricultural intensification production technology. Background technique [0002] Sulfonylurea herbicides are currently the most widely used herbicides in the world. It was successfully researched by DuPont in the 1970s, and the wheat field herbicide chlorsulfuron was first developed in 1982, and later developed Many high-efficiency, broad-spectrum, low-toxicity, high-selectivity sulfonylurea herbicides have been produced. However, the most prominent problem of sulfonylurea herbicides is the long-term residual phytotoxicity of subsequent crops. Due to the weak migration and leaching of this type of herbicide, when the residue reaches a certain dose, it will cause pesticid...

AI Technical Summary

Problems solved by technology

However, the most prominent problem of sulfonylurea herbicides is the long-term residual phytotoxicity of subsequent crops. Due to the weak migration and leaching of this type of herbicide, when the residue reaches a certain dose, it will cause pesticide damage to subsequent crops. Harmful

Some fields where long-term residual herbicides have been used for a long time also have accumulated herbicide residues, which seriously affects the growth of subsequent crops, forming the phenomenon of "cancer fields"

Moreover, the harmful pesticides have also changed the soil, made the soil alkalized, polluted the environment, caused a serious biological imbalance, and caused many small animals and birds to become extinct. The residual harmful substances also seriously affect human health. Physical health and the reproduction of species in the world
