Abstract
The invention provides a bactericidal composition containing cyflufenamid and fenamidone. The active ingredients of the bactericidal composition have synergetic interaction; according to the bactericidal composition, the prevention spectrum can be expanded and the using cost is reduced.
Description
The application is dividing an application of " bactericidal composition that contains cyflufenamid " application for a patent for invention, original application day: on April 7th, 2013, application number: 2013101166832
Technical field
The present invention relates to the bactericidal composition that contains cyflufenamid, be specifically related to a kind of contain cyflufenamid and bactericidal composition, belong to plant protection field, composition is for preventing and treating the powdery mildew, leaf spot, scab, bakanae disease, downy mildew, brown spot etc. of grain reality, cotton, oil plant, fruit tree, vegetables, flowers etc.
Background technology
Cyflufenamid belongs to the new type bactericide of oxime ethers, is a kind of protective fungicide of Japanese Cao Da company exploitation, and the powdery mildew of various plants, leaf spot, scab, bakanae disease, downy mildew, brown spot etc. are had to good effect.Carrying out the research of compounded technology, is to carry out synergy research, expanding prevention spectrum, reduce use cost, delay drug-fast effect.At present less about the report of cyflufenamid and other sterilization component composition research.Inventor, by the large quantity research to the composite effect of cyflufenamid, has found some beyond thought effects.
Summary of the invention
The object of the present invention is to provide the bactericidal composition that contains cyflufenamid, it is that the sterilization component of two kinds of different structures, the different mechanisms of action is carried out composite, be expanding prevention spectrum and the effective way that improves drug effect, the more important thing is and avoid or delay the generation of disease to new composition resistance.For realizing object of the present invention, inventor is composite with the compound with sterilization component by cyflufenamid, for preventing and treating the disease on crop, lawn.
The object of the invention is to realize by following measures.
The bactericidal composition that contains cyflufenamid, is characterized in that said composition comprises A and two kinds of components of B of synergy effective dose, and A is cyflufenamid, and B is selected from methoxy acrylic sterilization component pyraclostrobin, ZJ0712, azoles bacterium ester, SYP-3375, a kind of in 2-cyano-3-amino-3-phenylancryic acetate, or azole sterilization component propiconazole, Tebuconazole, Flusilazole, Triadimenol, metconazole, epoxiconazole, own azoles alcohol, bromuconazole, a kind of in triticonazole, or sulfur-bearing class sterilization component ambam, S-Ethyl ethylthio sulfonate, tpn, sulphur, tmtd, captan, asomate, sulfonat, a kind of in fenaminosulf, or amide-type sterilization component dimethomorph, zoxamide, metalaxyl, fluopicolide, a kind of in efficient M 9834, or biogenic substances sterilization component polyoxin, kasugarnycin, chitosan oligosaccharide, streptomycin, Ningnanmycin, a kind of in jinggangmeisu, or imidazoles sterilization component Fenamidone, or oxazole class sterilization Cheng Fen famoxadone, a kind of in Wakil, or the phonetic phenol of miazines sterilization component second, a kind of in fluorine mepanipyrim, or organic phosphates sterilization component iprobenfos, a kind of in edifenphos.In composition, the ratio of quality and the number of copies of A component and B component is 1:100-20:1.
In composition of the present invention, more preferably technical scheme is: component A is selected from cyflufenamid, B component is selected from B and is selected from methoxy acrylic sterilization component pyraclostrobin, ZJ0712, a kind of in azoles bacterium ester, or azole sterilization component is selected from propiconazole, Tebuconazole, Flusilazole, Triadimenol, metconazole, epoxiconazole, a kind of in own azoles alcohol, or sulfur-bearing class sterilization component ambam, S-Ethyl ethylthio sulfonate, tpn, sulphur, tmtd, a kind of in captan, or amide-type sterilization component dimethomorph, zoxamide, a kind of in metalaxyl, or biogenic substances sterilization component polyoxin, kasugarnycin, chitosan oligosaccharide, streptomycin, a kind of in Ningnanmycin, or imidazoles sterilization component is selected from Fenamidone, or oxazole class sterilization Cheng Fen famoxadone, a kind of in Wakil, or the phonetic phenol of miazines sterilization component second, a kind of in fluorine mepanipyrim.Between A, B two components, more preferably ratio of quality and the number of copies is 1:40-10:1.
The 1-90% of the quality sum composition gross mass of A component and B component in the present composition.
