Abstract

The invention relates to a bactericidal composition comprising 2-methylsulfonyl-5-(2,4-dichlorophenyl)-1,3,4-oxadiazole and kasumin. The weight ratio of the two effective components is (1-90):(90-1). The weight percent of the effective components in the bactericide is 5-80%, preferably 10-70%; and the rest is allowable aids and carriers in agricultural chemicals. The composition has an obvious synergistic action, can lower the consumption of the agricultural chemicals, and is environment-friendly and safe.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition containing dicloconazole and kasugamycin. Background technique [0002] Dicloconazole is a kind of oxazole sulfone fungicide discovered by Guizhou University, and its chemical name is: 2-methylsulfone-5-(2,4-dichlorophenyl)-1,3,4- Oxadiazole, which has the molecular formula C 4 h 7 Cl 2 o 4 P, the relative molecular mass is 220.98. It is a new type of fungicide, and it is a low-toxic and safe green chemical pesticide. However, this pesticide has not been widely used, making it play an increasingly important role in the creation of new ultra-efficient pesticides. [0003] Kasugamycin is produced by Streptomyces kasuga ( Streptomyces kasugaensis ) produced by aminoglycoside antibiotics. Since its development, kasugamycin has been widely used in agriculture in Asia and South America. It is particularly effective in the control of ric...
