A kind of bactericidal composition containing bacillus amyloliquefaciens and prochloraz and application thereof

Abstract

The invention discloses a bactericidal composition containing bacillus amyloliquefaciens and prochloraz and application thereof. The composition uses bacillus amyloliquefaciens and prochloraz as active components, and the mass ratio thereof is 6:1 to 1:6 . The invention also discloses the preparation method of the agricultural formulation type wettable powder and suspension concentrate of the bactericidal composition and its application in preventing and treating strawberry anthracnose and gray mold. Compared with a single agent, the fungicidal composition of the present invention has obvious synergistic effect on the prevention and treatment of strawberry anthracnose and gray mold, and can significantly improve the control effect; it reduces the effect of strawberry anthracnose and gray mold on prochloraz and bacillus Potential drug resistance risk; reduce the use of chemical pesticides, reduce the cost of drug use, effectively improve environmental pollution and agricultural product residues, and be safe for humans, animals, beneficial organisms, and the environment, so it can be widely used in strawberry anthracnose and Botrytis cinerea Disease prevention and treatment.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a kind of bacillus amyloliquefaciens ( Bacillus amyloliquefaciens ) and prochloraz composition and its application in the control of strawberry anthracnose and strawberry gray mold. Background technique [0002] Strawberry has bright color, strong flavor, rich nutrition and high economic benefits. It is one of the high-grade fruits in the current fruit market. It is widely cultivated in many provinces and cities in my country, and the planting area is increasing 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 protective land cultivation mode for planting. Under this cultivation mode, due to the relatively closed environment, poor ventilation and air permeability, suitable temperature and humidity, and excessive application of chemical...
