Abstract

The invention relates to bacillus amyloliquefaciens and bismerthiazol compound wettable bactericidal powder and application thereof. A finished agent comprises effective active ingredients, aids and filling auxiliary materials, and is characterized in that the effective active ingredients account for 10-85 percent by weight of the finished agent and consist of bacillus amyloliquefaciens and bismerthiazol; in the effective active ingredients, the weight percent of bacillus amyloliquefaciens is 10-90 percent. During application, the finished agent is diluted and uniformly sprayed to rice leaves for preventing and treating rice Bacterial streak or bacterial blight of rice. The finished agent has the advantages that bacillus amyloliquefaciens and the chemical agent, bismerthiazol, are mixed according to a certain ratio, a synergistic effect of microbes and chemical agents can be fully exerted, the advantages are complemented with one another, the prevention and treatment range is widened, the dosage of the chemical agent is reduced, the administration cost is reduced, the prevention and treatment effect is improved, the ecological environment is improved, and the residue amount of the chemical agent in rice is reduced.

Description

technical field [0001] The invention relates to a wettable bactericidal powder compounded by Bacillus amyloliquefaciens and thiacumazole and its application, especially a wettable bactericidal powder composed of Bacillus amyloliquefaciens and thiacumazole and its use in preventing and treating bacterial diseases of rice Applications. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, higher and higher requirements are put forward for the safety of food products. Rice diseases caused by bacteria are one of the important diseases in rice production in my country, especially in the south, and are also one of the important limiting factors to ensure the safety of rice production in my country. At present, the disease occurs in an area of ​​more than 20 million mu all year round, causing a loss of 5-10% of rice yield, and even more than 30% in severe cases. In traditional rice production, the preven...
