Problems solved by technology

[0004] Due to the long-term use of the above two agents alone, it is easy to lead to the emergence of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a significant increase in dosage, shortened spraying cycles, and poor use effects, which increases costs. The use of a large number of pesticides makes t

Abstract

The invention belongs to the technical field of pesticides and specifically relates to compounded bactericidal composition missible oil containing tetramycin and bismerthiazol and application of the bactericidal composition in preventing rice bacterial leaf blight. In the composition, a weight ratio of the tetramycin to the bismerthiazol is 1:5-1:200; synergism is achieved by compounding; a charging sequence, operation, and the like are optimized by adopting an emulsion in water and a preparation method thereof, so that the original preparation technology is improved. Besides, the bactericidal composition has good prevention and treatment effect for rice bacterial leaf blight, and has a good effect in delaying drug resistance of pathogenic bacteria.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition compounded with wuningmycin and eubacazole, and its application in rice bacterial blight. Background technique [0002] Wuningmycin, also known as tetramycin and 11371 antibiotic, is derived from an actinomycete isolated and screened from soil samples in Wuzhou, Guangxi, Streptomyces ahygroscopicn wuzhouensisn subsp. Streptomyces. Metabolites produced during fungal growth are generally produced by engineered fermentation. This product has a wide bactericidal spectrum, and has a strong killing effect on 26 known pathogenic fungi of the three major categories of flagella, ascomycetes and deuteromycotina fungi. It is suitable for the prevention and control of various fungal diseases of various crops. Especially for fruit tree rot, spotted leaf spot; cotton yellow (fusarium) wilt; soybean root rot; rice bacterial blight and sheath blight, ...
