Compared with prior art, the beneficial effects of the invention are as follows：The present invention bactericidal composition on one point in the range of have very
Good synergistic effect, prevention effect significantly improves compared with single dose；Field dosage can be greatly decreased in the present invention, reduce life
Production and use cost, reduce residues of pesticides, are advantageous to the sustainable development of environment；Have in bactericidal composition disclosed by the invention
It is different to imitate the mechanism of action of composition, is advantageous to avoid or delays the generation of disease drug resistance；In addition, the present invention can also expand it is anti-
Spectrum is controlled, while crop downy mildew, late blight and powdery mildew is prevented and treated, virosis can be prevented and treated.
Embodiment
The technical scheme in the embodiment of the present invention is clearly and completely described below, it is clear that described embodiment
Only part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the common skill in this area
The every other embodiment that art personnel are obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
Bactericidal composition of the present invention using bactericidal composition of the present invention using benzene metsulfovax as a kind of active ingredient, with azoles mepanipyrim
For another active ingredient, the combination between them has obvious synergistic function to downy mildew, late blight and powdery mildew,
Rather than just the simple addition of two kinds of drug actions, specifically it is illustrated with following biologicall test example.
The Toxicity Determination of Assays Example 1, benzene metsulfovax and azoles mepanipyrim compounding to cucumber downy mildew
