AI Technical Summary

Problems solved by technology

[0006] (1) Existing pesticides are only aimed at pests in the planting land, and have no significant or no control effect on diseases in the planting land, and the existing insecticides are only effective against certain pests
[0007] (2) When the existing insecticides are used to prevent and control pests in soybeans, they have certain side effects on soybeans, poor safety, and have a certain inhibitory effect on their growth, thereby reducing crop yields
[0008] (3) After the application of existing pesticides is completed, it is easy to cause pesticide toxin residues, which will affect the quality of soybeans and affect the food safety of soybeans

Abstract

The invention provides a biopesticide containing Bacillus sphaericus and used for preventing and treating soybean diseases and pests and a preparation method of the biopesticide. The biopesticide is prepared from, by mass, 15-24 parts of buprofezin, 3-5 parts of Bacillus sphaericus, 2.5-3.5 parts of purple bergenia herb extracts, 1.5-2.5 parts of cortex meliae powder, 2.3-3.6 parts of potassium nitrate, 5-6 parts of dispersing agent, 1.5-2.6 parts of wetting agent, 2.6-3.6 parts of diffusant, 7-13 parts of kieselguhr and 13-21 parts of water. The prepared biopesticide has a good prevention and treatment effect in soybean plantation fields 15 days after being applied, and the prevention effects on frequently-seen injurious pests including soybean pod borers, red spider mites, clanis bilineata walkers, bean borers and Ascotis selenaria Schiffermuller et Denis in soybean plantation fields reach 96.1-99.8%, 88.7-91.5%, 94.4-98.6%, 83.2-86.9% and 73.8-78.9% respectively.

Description

technical field [0001] The invention relates to a biopesticide containing bacillus sphaericus for preventing and controlling soybean diseases and insect pests and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Bacillus sphaericus is an aerobic bacillus that is widely distributed in nature and forms subterminal expanded sporangia and spherical spores. The poisonous effect of Bacillus sphaericus on different pests is mainly realized by the toxin protein produced by it. It has been proved that two different types of toxin proteins can be produced during its growth and development, one is the crystal toxin protein present in all highly virulent strains; the other is present in some high-virulence strains of low-virulence strains Mtx toxin protein. [0003] Existing chemical insecticides have a certain degree of toxicity and side effects on crops, and will cause environmental pollution such as land and water sources t...
