Abstract

The invention discloses a compound composition and a preparation thereof. The compound composition is prepared from methylsulfonyl azole and azoxystrobin, wherein the chemical name of methylsulfonyl azole is 2-(4-fluorophenyl)-5-methylsulfonyl-1,3,4-oxadiazole; the weight ratio of methylsulfonyl azole to azoxystrobin is (20-1):(1-20), and preferably (10-1):(1-10); and the compound composition is 0.1-90 percent of a bactericide. The compound composition and preparation thereof have remarkable synergetic effect for preventing and controlling diseases, and can be used for improving the germicidal efficiency, reducing drug usage, and reducing environment pollution and pesticide residue; and generation of drug resistance of bacteria can be retarded or resisted due to increase of acting sites. The composition and bactericide do not have remarkable adverse influence to tested crops, have high safety, and accord with the safety requirement for pesticide preparations.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition and a preparation in which two bactericidal active ingredients are mixed. Background technique [0002] Azoxystrobin was developed by Syngenta, and its molecular formula is: C 22 h 17 N 3 o 5 , it belongs to methoxyacrylate fungicides, azoxystrobin has wide bactericidal activity, almost all fungal diseases (Ascomycetes, Basidiomycetes, Oomycetes and Deuteromycetes) diseases such as powdery mildew, rust, It has good activity on diseases such as glume blight, scab, downy mildew and rice blast. However, due to the single action site of azoxystrobin, a large number of single doses are used multiple times, most diseases have developed strong resistance to it, and the control effect is extremely unsatisfactory. [0003] To this end, Guizhou University has independently developed a new type of fungicide with independent intellectual property rights, "a cla...
