Microbial composite pesticide

Abstract

The invention discloses a microbial composite pesticide which is prepared from 90-94 parts by mass of microbial fermentation mixed liquid and 6-10 parts by mass of synergists, wherein the microbial fermentation mixed liquid is prepared from bacillus thuringiensis fermentation liquid, bacillus subtilis fermentation liquid, bacillus amyloliquefaciens fermentation liquid, bacillus cereus fermentationliquid, bacillus megatherium fermentation liquid, bacillus licheniformis fermentation liquid and bacillus polymyxa fermentation liquid; and the synergists are prepared from diethyl aminoethyl hexanoate, calcium acetate, zinc sulfate, ammonium nitrate, chitosan, tea saponin and urea. The microbial composite pesticide disclosed by the invention has the advantages that strains of different bacterialgenera are mixed, and different bacterial genera have selectivity to different plant diseases and insect pests, so that multiple plant diseases and insect pests can be prevented; the microbial composite pesticide especially has better prevention and treatment effects on multiple insects of lepidoptera, orthoptera, diptera, coleoptera, hemiptera, hymenoptera and ephemeroptera; and pests are not easy to produce drug resistance, natural enemies of the pests are protected, and the ecological environment is effectively balanced.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a microbial composite pesticide. Background technique [0002] At present, many countries in the world use chemical pesticides in large quantities to cause environmental pollution. Many chemical pesticides also pose a threat to beneficial organisms because they are not selective. At the same time, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants. resulting in the accumulation of pollutants. [0003] Microbial pesticide is a new industry in the pesticide industry in the 21st century. It can overcome the pollution of chemical pesticides to the ecological environment and reduce the amount of pesticide residues in agricultural by-products. The rate of increase will favorably promote rural economic growth and increase farmers' income, and the social benefits are immeasurable. A large amount of microbial insecticides have ...

The application number is CN201510103305.X, which discloses a microbial insecticide composition for preventing and controlling red imported fire ants. It uses a mixture of Beauveria bassiana and thiacloprid, but thiacloprid is a chemical pesticide, and it is easy to cause residues

At present, microbial pesticides are mainly made of a single strain or a mixture of strains of different genera, or mixed with chemical pesticides, the bactericidal effect is reduced, and the chemical residue is high
