Abstract
The present invention provides one kind of synergistic germicide composition containing Kresoxim-methyl and propiconazol. The synergistic germicide composition contains Kresoxim-methyl in 5-45 wt%, propiconazol in 1-40 wt%, assistant and excipient for the rest. It may be used to prevent and control various plant diseases of fruits, molens, vegetable, rice, etc. It has the synergistic effect and low consumption.
Description
Technical field
The present invention relates to a kind of bactericidal composition and uses thereof, especially a kind of is the bactericidal composition and the application thereof of main active with kresoxim-methyl and propiconazole.
Background technology
Kresoxim-methyl (kresoxim-methyl) is a kind of efficient, wide spectrum, new type bactericide.Diseases such as powdery mildew of strawberry, melon powdery mildew, powdery mildew of cucumber, pear scab had good preventive effect.Kresoxim-methyl not only has the bactericidal activity of wide spectrum, simultaneously with excellent protection and therapeutic action.There is not cross resistance with other bactericide commonly used, and longer than the conventional sterilization agent lasting period.Have the selectivity of height, to crop, people and animals and beneficial organism safety, pollution-free substantially to environment.Kresoxim-methyl has good active to fungus-caused multiple diseases such as imperfect fungus, sac fungi, basidiomycetes, Oomycetes, but the former medicine production of kresoxim-methyl is less in China, and its price is high, is difficult to prevent and treat aspect the disease in the farmland use.
Propiconazole (propiconazol) is the systemic fungicide with protection and therapeutic action; can be absorbed by root, stem, leaf portion, and can be soon in the plant strain body on conduction, the control sac fungi; the disease that basidiomycetes and imperfect fungus cause belongs to the biosynthetic inhibitor of ergosterol.Ergosterol plays an important role in the formation of fungal cell membrane, and propiconazole is by disturbing C
14-demethylation and hinder the biosynthesis of ergosterol in the fungus body, thus the fungi growth breeding destroyed, play protection and therapeutic action.Propiconazole is except that invalid to the phycomycete disease, and the multiple diseases that Saccharomyces, basidiomycetes number, Dendrochium fungi are caused on cereal crops, vegetables, fruit and ornamental plants is effective.
Propiconazole has certain therapeutic action for the pathogen of crop pest, but single use propiconazole can not reach the effect that prevents and treats crop pest.
Summary of the invention
The invention provides a kind of bactericide that contains kresoxim-methyl and propiconazole, this bactericidal composition has Synergistic to be done to have, and can reduce dosage, be applicable to control cereal class, various melon, really, crop pest such as vegetables.
Another object of the present invention provides above-mentioned bactericidal composition in the application on control cereal class and melon or fruit type crops disease.
Technical scheme of the present invention is as follows:
A kind of Synergistic bactericidal composition that contains kresoxim-methyl and propiconazole is characterized in that it is an effective ingredient with kresoxim-methyl and propiconazole, and wherein the weight percentage of kresoxim-methyl is 5～45%, and the weight percentage of propiconazole is 1～40%, and surplus is auxiliary agent and carrier.
The preferred weight percentage composition of effective ingredient kresoxim-methyl is 10～45% in the bactericidal composition of the present invention, and the preferred weight percentage composition of propiconazole is 2～30%.
Above-mentioned bactericidal composition is re-dubbed pulvis, wetting powder, suspension emulsion, emulsifiable concentrate or granule etc. in interior common formulations by effective ingredient kresoxim-methyl and propiconazole and auxiliary agent and carrier.
The application of above-mentioned bactericidal composition on control cereal class and melon or fruit type crops disease.
Bactericidal composition of the present invention is by effective ingredient kresoxim-methyl and propiconazole and auxiliary agent and carrier is composite forms, and can also add suitable auxiliary material in case of necessity.Wherein Chang Yong auxiliary agent is as calcium dodecyl benzene sulfonate, phenethyl phenol polyethenoxy ether, castor oil APEO, dimethylbenzene, phenethyl phenol polyethenoxy ether phosphate, peaceful newborn 44#, OP-10, Nongru-700 #, polyoxyethylene nonylphenol ether, deionized water, propane diols, NNO (two sodium butylnaphthalenesulfonate formaldehyde condensation products) etc.Common carrier as: draw back powder LS, white carbon, add kaolin, macromolecule silicate, talcum powder, carboxymethyl cellulose, precipitated calcium carbonate etc.
The used kresoxim-methyl of the present invention is an acid amide fungicides, and propiconazole is an azoles fungicide, and both have identical mechanism of action, and being mixed mutually can not produce conflict, but Synergistic reduces dosage.The present invention is specially adapted to prevent and treat effect diseases such as cereal class, various melon and fruit, vegetables, banana, capsicum, paddy rice, mango, pineapple, as wheat powdery mildew, pepper anthracnose, balsam pear scab, scutellum rot of orange, powdery mildew of cucumber, early blight of tomato and late blight.
