Problems solved by technology

However, at present, there are still some problems in the application of Bacillus amyloliquefaciens in agricultural production. There are few strains with high biological activity screened out, single pesticide variety preparation, large dosage, low control effect and slow effect. Active substances such as The number of viable bacteria is reduced, the activity of spores is weakened, and the strain performance is unstable, etc.

Abstract

The invention discloses a bactericidal and insecticidal composition containing Bacillus amyloliquefaciens and matrine. The composition comprises an effective composed of Bacillus amyloliquefaciens and matrine, and a suitable agricultural assistant is added to prepare a common pesticide dosage form. The has a very good prevention and control effect on strawberry aphids, strawberry gray molds, strawberry powdery mildew and other various crop pests and fungal diseases, can improve the prevention and control efficiency, reduces the dosage of chemical pesticides, effectively reduces the ecologic destroy and environmental pollution, and is safe to human and animals, beneficial organisms and environment.

Description

technical field [0001] The invention belongs to the field of agricultural bactericides and insecticides, and in particular relates to a bactericidal and insecticidal composition of bacillus amyloliquefaciens and matrine. Background technique [0002] Bacillus amyloliquefaciens (Bacillus amyloliquefaciens) is a Gram-positive bacillus, a bacterium with high affinity with Bacillus subtilis, widely distributed in nature. During the growth process of Bacillus amyloliquefaciens, a series of metabolites can be produced that have extensive activity of inhibiting fungi and bacteria, which has broad application prospects in biological control and has gradually become a microorganism with potential for the development of biological pesticides. Currently, Bacillus amyloliquefaciens is used Studies on the prevention and control of strawberry gray mold, rice bacterial streak and rice bakanae disease have been reported. However, at present, there are still some problems in the application...
