Abstract

The invention relates to a bactericide composition which consists of tetraconazole and difenconazole. The bactericide comprises two effective components of the tetraconazole and the difenconazole, an auxiliary agent and an excipient, wherein the weight percentage of the tetraconazole and the difenconazole is 1-30:1-60. The bactericide can generate higher cooperative synergism, overcome and delay the disease drug resistance, enlarge the prevention and curing spectrum, reduce the consumption of organic solvents and the drug use cost and lighten the toxicity. The bactericide composition can be used for preventing and curing various diseases on grains, fruit trees and vegetable crops, particularly for preventing and curing altemaria mali, wheat powdery mildew and black sigatoka of bananas. The effect of the bactericide composition is obviously higher than that of signal agent use.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and relates to a fungicide compounded with tetrafluconazole and difenoconazole, which is used for the prevention and treatment of diseases on grains, fruit trees and vegetables. technical background: [0002] Tetraconazole, the English name is (tetraconazole), the chemical name is (RS)-2-(2,4-dichlorophenyl)-3-(1H-1,2,4-triazol-1-yl) Propyl 1,1,2,2-tetrafluoroethyl ether, [0003] The structural formula is: [0004] [0005] Tefluconazole is a triazole fungicide developed by Italian company Eseg, and Tefluconazole is a sterol demethylation inhibitor. Because of its good systemic properties, it can be quickly absorbed by plants and conducted internally; it has good protective and therapeutic activities, with a lasting period of 6 weeks. The drug is used for the prevention and control of various diseases of cereal crops such as wheat, barley, oats, rye, fruit trees such as bananas, grapes...
