Description

Contain pyrrole metsulfovax and antibiotic bactericidal composition
The application is the divisional application of patent of invention " bactericidal composition that contains pyrrole metsulfovax ", and former number of patent application is 2013100910407, and the applying date is on March 20th, 2013.
Technical field
The present invention relates to contain pyrrole metsulfovax and antibiotic bactericidal composition, belong to plant protection field, relate to the bactericidal composition that contains pyrrole metsulfovax, said composition is used for preventing and treating gray mold, powdery mildew, downy mildew, stalk break, rust disease, scab etc.
Background technology
Pyrrole metsulfovax is the new type bactericide of amide containing structure, to multiple kinds of crops disease there is good preventive effect, especially gray mold, powdery mildew, downy mildew are had to very high effect.For Reasonable Protection medicament, delay germ to the drug-fast generation of new medicament and improve the control efficiency of medicament, be necessary to carry out rational composition research.The complex preparation that has had at present pyrrole metsulfovax and other bactericide, the present invention found through experiments the reasonable bactericidal composition that contains pyrrole metsulfovax of other effects that prior art is not also found.These bactericidal compositions have unforeseeable technique effect.
Summary of the invention
The object of the present invention is to provide and contain pyrrole metsulfovax and antibiotic bactericidal composition, it be two kinds of different structures are carried out composite, but expanding prevention spectrum and improve the effective way of drug effect be the more important thing is and avoided 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 pyrrole metsulfovax, for preventing and treating the disease of crop.
The object of the invention is to realize by following measures.
The invention provides a kind of bactericidal composition that contains pyrrole metsulfovax, it is characterized in that said composition comprises A component and two kinds of active components of B component of effective dose, A component is pyrrole metsulfovax, and B component is selected from the one in jinggangmeisu, kasugarnycin, polyoxin, Ningnanmycin.
In above-mentioned composition, preferred, the ratio of quality and the number of copies of A component and B component is 1:40-40:1, and preferred, the ratio of quality and the number of copies of A component and B component is 10:1-1:20.
In above-mentioned composition of the present invention, preferred, B component is selected from the one in kasugarnycin, polyoxin.
In above-mentioned composition of the present invention, the quality sum of A component and B component accounts for the 1-90% of composition gross mass.
Above-mentioned composition of the present invention can be made into suspending agent, wetting powder, water dispersible granules, aqua, microemulsion or aqueous emulsion.
The present invention also provides above-mentioned composition for preventing and treating the method for crop pest, it is characterized in that composition to be applied to crop or crop part by spraying, filling root or seed dressing.。
The present invention also finds, above-mentioned composition, in the situation that active component is used total amount to reduce separately, has good control efficiency to graw mold of tomato, cucumber downy mildew, wheat powdery mildew, and synergistic effect is obvious.
The present invention also provides above-mentioned composition for preventing and treating the purposes of various agricultural disease of crop, it is characterized in that described disease is the fungus-caused graw mold of tomato of Fungi Imperfecti, scab etc., the fungus-caused downy mildew of Mastigomycotina, late blight, peronospora tabacina etc., the fungus-caused powdery mildew of Ascomycotina, anthracnose, leaf spot etc., rust that Basidiomycotina causes, smut etc.
In such use, described crop is preferably tomato, cucumber, wheat, paddy rice, watermelon, apple, grape, oranges and tangerines, pears, lichee or flowers etc.
Beneficial effect of the present invention is:
1, synergistic effect is obvious: composition shows good synergistic effect in certain ratio range, has improved the protection effect of composition.
2, expanding prevention spectrum: composition can be prevented and treated the multiple diseases in agricultural production.
3, reduce use cost: because compositely thering is the preventive effect of raising, control spectrum increases, and has reduced access times, has reduced use cost;
4, delay pesticide resistance: the composition of two kinds of different mechanism of action is composite, pathogen is difficult for developing immunity to drugs, and delays pathogen to the drug-fast generation of single dose.
Embodiment
Following examples are to further illustrate of the present invention, but the present invention is not confined to composition and purposes in present embodiment.
The control efficiency of embodiment 1 pyrrole metsulfovax composition to graw mold of tomato
Single compound or composition are prepared into the mother liquor of 1000mg/L with organic solvent dissolution.According to biological activity determination trial test, a certain amount of above-mentioned mother liquor is diluted with 0.1% Tween 80, be mixed with the concentration needing.During mensuration, first liquid medicine jet is imposed on to potted tomato plant, then inoculate pathogen, moisturizing is cultivated after 24h, is placed in greenhouse and cultivates, and measures the percentage that plant leaf surface infects after certain hour.Use Abbot formula, convert percentage to preventive effect.
