Bactericidal composition containing bacillus amyloliquefaciens and difenoconazole

Abstract

The invention discloses a bactericidal composition containing bacillus amyloliquefaciens and difenoconazole, and application of the bactericidal composition. The bactericidal composition is prepared by taking the bacillus amyloliquefaciens and the difenoconazole as active components, wherein the mass ratio of the bacillus amyloliquefaciens to the difenoconazole is equal to (5 to1)-(1 to 5). The invention also discloses preparation methods of agricultural preparation forms, i.e., wettable powder and a suspending agent, of the bactericidal composition, and application of the agricultural preparation forms in control of strawberry anthracnose, powdery mildew and gray mold. Compared with a single agent, the bactericidal composition provided by the invention has an obvious synergistic effect for the strawberry anthracnose, the powdery mildew and the gray mold, and can remarkably improve prevention and control effects; the potential drug resistance risk of the strawberry anthracnose, the powdery mildew and the gray mold for the difenoconazole and the bacillus is reduced; after the bactericidal composition is used, the consumption of chemical pesticide is reduced, the pesticide cost is lowered, and the problems of environmental pollution and residue of agricultural products are effectively solved; the bactericidal composition is safe to humans and animals, good for organisms and environmentally safe, thus being widely applied to the control of the strawberry anthracnose, the powdery mildew and the gray mold.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a kind of bacillus amyloliquefaciens ( Bacillus amyloliquefaciens ) and difenoconazole and its application in preventing and treating strawberry anthracnose, strawberry powdery mildew and strawberry gray mold. Background technique [0002] Strawberry fruit is bright red and beautiful in shape, soft and juicy, rich in fragrance, sweet and sour, and rich in nutrition. It is one of the high-end fruits in the current fruit market, deeply loved by consumers, and has a broad market prospect. In recent years, the planting area in our province has expanded rapidly, and it has been widely cultivated in many provinces and cities in my country, and the planting area is showing an increasing trend year by year. In order to improve the yield and quality of strawberry products and prolong the market supply time, most areas in my country currently use greenhouses and solar greenhouses as the main p...
