Bactericidal composition containing cyclohexyl flusulfamide and fluxapyroxad and application of bactericidal composition

Abstract

The invention discloses a bactericidal composition containing cyclohexyl flusulfamide and fluxapyroxad and an application of the bactericidal composition. The bactericidal composition takes cyclohexyl flusulfamide and fluxapyroxad as major active ingredients at a mass ratio ranging from 1:50 to 70:1. The bactericidal composition is applicable to prevention and control of diseases of cereals, fruit trees and vegetables, has a higher synergetic effect, overcomes and retards drug resistance of pathogens, is high in bactericidal speed and long in lasting period, lowers application cost, and has an obviously better prevention and control effect than a single agent. The composition can be used for the prevention and the control of fungoid diseases of crops, particularly the fungoid diseases such as venturia inaequalis, sclerotiniose, botrytis, powdery mildew and brown blotch, and has a better effect than that of a single agent.

Description

[0001] Technical field: [0002] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with cyclohexasulfame and flufenapyramide as main active ingredients and its application. Background technique [0003] Molecular formula of cyclohexasulfame: C 13 h 13 CIF 3 NO 3 S. Chemical name: N-(2-trifluoromethyl-4-chlorophenyl)-α-oxocyclohexylsulfonamide. It has strong preventive, therapeutic and osmotic activities, and has high persistence. The field test results show that it can effectively control Botrytis cinerea, rape sclerotinia, cucumber brown spot and scab. [0004] Fluxapyroxad, molecular formula: C 18 h 12 f 5 N 3 O. Flufenapyramide is an amide fungicide, which mainly inhibits the mitochondrial succinate dehydrogenase, hinders the tricarboxylic acid cycle, causes amino acid and sugar deficiency, reduces energy, and interferes with cell division and growth. It has protective and therapeutic effects. It...

Problems solved by technology

[0005] At present, the prevention and control of plant pathogens is becoming more and more difficult. The main reasons are as follows: First, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased. The second is that the current climate is abnormal, which provides certain conditions for the outbreak of the disease; the third is the long-term selective influence of chemical drugs, which makes the resistance of pathogenic bacteria increase year by year under the continuous pressure of drug selection. The effect is greatly reduced

In summary, the current plant disease control is facing major challenges
