Abstract

The invention discloses a bactericidal composition containing fenbuconazole and a thiocarbamate compound. The bactericidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is fenbuconazole, the active ingredient B is selected from any one of the following bactericides: mancozeb, propineb, zineb and thioneb, and the weight percentage ratio of the active ingredient A to the active ingredient B is (1-40%): (1-80%). The composition can control various crop diseases, such as alternaria mali, cladosporium cucumerinum, leaf spot, powdery mildew, ring spot, rust disease, leaf blight, anthracnose, downy mildew, brown blotch and plague, has remarkable synergistic action, has high safety to crops and has the advantages of resistance to rain scouring, lasting drug effect, small dosage and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the preparation and application of a fungicidal composition containing two active components. Background technique [0002] Fenbuconazole, English name: fenbuconazole, molecular formula: C 19 h 17 ClN 4 , chemical name: 4-(4-chlorophenyl)-2-phenyl-2(1H-1,2,4-triazol-1-ylmethyl)butyronitrile, structural formula: [0003] [0004] Nibenazole is a sterol demethylation inhibitor, a systemic conduction fungicide, which can inhibit the elongation of pathogenic fungus hyphae and prevent germinated pathogenic spores from invading crop tissues. Using it during the incubation period of the bacteria can prevent the growth of the bacteria, and using it after the onset of the disease can deform the next generation of spores and lose the ability to continue to infect. It has both preventive and therapeutic effects on diseases. [0005] Mancozeb (mancozeb), chemical name: complex salt of...
