Bactericidal composition containing thifluzamide and triazole compounds

Abstract

The invention relates to a bactericidal composition containing thifluzamide and triazole compounds. The bactericidal composition comprises an active component A and an active component B, wherein the active component A is selected from thifluzamide, and the active component B is selected from one of metconazole, triticonazole, imibenconazole or fenbuconazole; the weight proportion of the effective active component A to the effective active component B is (1-80 percent): (1-80 percent); and an accessory ingredient and an excipient are added into the effective active components to prepare wettable powder, water dispersible granules, a suspending agent, suspended emulsion or a suspension seed coating agent. The bactericidal composition provided by the invention is used for preventing and curing rice blast, banded sclerotial blight, septoria nodorum, a rust disease, powdery mildew, anthracnose, botrytis, downy mildew, alternaria mali Roberts, a rot disease, a tan disease, cladosporium cucumerinum, leaf spot, an epidemic disease, a black rot disease, a brown spot disease, a scab disease and leaf blight and has the effects of less dosage, rain washing resistance and obvious synergia.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing thifluzamide and triazole compounds on crop diseases. technical background [0002] Thiofuramide, English name: thifluzamide, molecular formula: C 13 h 6 Br 2 f 6 N 2 o 2 S, chemical name: 2,6-dibromo-2-methyl-4-trifluoromethoxy-4-trifluoromethyl-1,3-thiazole-5-carbonanilide, structural formula: [0003] Thiofuramide is a thiazole amide fungicide with strong systemic conductivity and long-lasting effect. Thiofuramide is a succinate dehydrogenase inhibitor, its main function is to inhibit the acid dehydrogenase in the tricarboxylic acid cycle of pathogenic fungi, leading to the death of the bacteria. Due to its fluorine content, it has strong competitiveness in biochemical processes, and it is not easy to recover once combined with substrates or enzymes. Thiofuramide is active against pathogenic fungi such as Rhizoc...
