Sterilizing composition containing chesulfamide and simeconazole and application thereof

Abstract

The invention discloses a sterilizing composition containing chesulfamide and simeconazole and an application thereof. Chesulfamide and simeconazole are taken as main effective ingredients of the sterilizing composition, wherein the mass ratio of chesulfamide to simeconazole is (1:50)-(70:1). The sterilizing composition can be used for preventing and treating cereal, fruit and vegetable diseases, has a higher synergistic effect, can overcome and delay the drug resistance of bacteria, is high in sterilizing speed and long in lasting period, is capable of reducing application cost and has a preventing and controlling effect which is better than that of single agent usage. The sterilizing composition can be used for preventing and controlling the fungus diseases of the crops, especially can be used for preventing and controlling scab, stalk break, banded sclerotial blight, powdery mildew, rust disease, gray mold, downy mildew, and the like, and has a better effect than that of single agent usage.

Description

[0001] Technical field: [0002] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with cyclohexasulfame and silfluazole 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] Silafluazole (Slmeconazole), molecular formula: C 14 h 20 FN 3 OSi. Sifluazole is a silicon-containing triazole fungicide developed by Sankyo Corporation (now Sankyo Agro Corporation) in 1991, and is an ergosterol biosynthesis inhibitor. Destroy and prevent the biosynthesis of ergoziol, an important component of the cell membrane of pathogens, so...

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
