Abstract
The invention discloses a pesticide composition containing penthiopyrad, which contains an active component A and an active component B, wherein the active component A is penthiopyrad; the active component B is selected from any one of polyoxin, phosethyl-Al, thiophanate-methyl, carbendazol, dithianon and triflumizole; and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition disclosed by the invention has higher activity for multiple diseases on multiple crops, and has obvious synergistic action, thereby widening the bactericidal spectrum. The composition has the characteristics of small dosage, rainfall erosion resistance and obvious synergistic action.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of composition pesticide containing pyrrole metsulfovax on corps diseases.
Technical background
Pyrrole metsulfovax (Penthiopyrad) chemical name: (RS)-N-[2-(1,3-dimethylbutyl)-3-thiophene phenyl]-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carboxamide, molecular formula: C

3oS.Pyrrole metsulfovax is the novel acid amide fungicides of Mitsui chemical company research and development, and it has different fungicidal spectrums from existing carboxyl acylamide bactericide.Except the same with existing carboxyl acylamide bactericide to basidiomycetes effectively, it is also effective to sac fungi, imperfect fungus, existing recommended for preventing and treating gray mold and the powdery mildew to other bactericide tool resistances.
Polyoxin, phosethyl-Al, thiophanate-methyl, carbendazim, dithianon, fluorine bacterium azoles all belong to common bactericide, are widely used in the disease of crops.
In the real process of agricultural production, preventing and treating the problem that disease the most easily produces is the generation of disease drug resistance.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistance disease.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect very obviously, synergy ratio very high composite just still less.Through inventor's research, discovery is mutually composite by pyrrole metsulfovax and polyoxin, phosethyl-Al, thiophanate-methyl, carbendazim, dithianon, fluorine bacterium azoles, there is within the specific limits good synergistic effect, and relevant composite about pyrrole metsulfovax and polyoxin, phosethyl-Al, thiophanate-methyl, carbendazim, dithianon, fluorine bacterium azoles, there is not yet relevant report at present at home and abroad.
Summary of the invention
The object of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect is good composition pesticide.
The present invention is achieved through the following technical solutions:
A kind of composition pesticide containing pyrrole metsulfovax, it is characterized in that containing active components A and active component B, active components A and active component B weight ratio are 1 ︰ 80 ~ 60 ︰ 1, described active components A is selected from pyrrole metsulfovax, and active component B is selected from a kind of in polyoxin, phosethyl-Al, thiophanate-methyl, carbendazim, dithianon, fluorine bacterium azoles; Active components A and the preferred weight ratio of active component B are 1 ︰ 60 ~ 40 ︰ 1; More preferably the weight ratio of pyrrole metsulfovax and polyoxin is 1 ︰ 20 ~ 20 ︰ 1, the weight ratio of pyrrole metsulfovax and phosethyl-Al is 1 ︰ 30 ~ 5 ︰ 1, the weight ratio of pyrrole metsulfovax and thiophanate-methyl is 1 ︰ 30 ~ 10 ︰ 1, the weight ratio of pyrrole metsulfovax and carbendazim is 1 ︰ 25 ~ 10 ︰ 1, the weight ratio of pyrrole metsulfovax and dithianon is 1 ︰ 20 ~ 20 ︰ 1, and the weight ratio of pyrrole metsulfovax and fluorine bacterium azoles is 1 ︰ 10 ~ 20 ︰ 1; The weight ratio that most preferably is pyrrole metsulfovax and polyoxin is 1 ︰ 9 ~ 9 ︰ 1, the weight ratio of pyrrole metsulfovax and phosethyl-Al is 1 ︰ 19 ~ 1 ︰ 1, the weight ratio of pyrrole metsulfovax and thiophanate-methyl is 1 ︰ 14 ~ 4 ︰ 1, the weight ratio of pyrrole metsulfovax and carbendazim is 1 ︰ 14 ~ 4 ︰ 1, the weight ratio of pyrrole metsulfovax and dithianon is 1 ︰ 9 ~ 9 ︰ 1, and the weight ratio of pyrrole metsulfovax and fluorine bacterium azoles is 1 ︰ 4 ~ 9 ︰ 1.
The disease of described composition pesticide for preventing and treating crops, described crops comprise cereal crops, legume crop, fiber crop, sugar [yielding, melon crop, fruits crop, dry fruit crop, hobby crop, root crop, oil crop, flowers crop, medicinal crop, raw material crop, green manure pasture crop; Described disease comprises rust, epidemic disease, stalk break, gray mold, downy mildew, leaf mold, head blight, powdery mildew, scab, rust, fusarium wilt, banded sclerotial blight, damping off, rice blast, spot defoliation, graywall, brown spot, leaf spot, ulcer disease, balck shank, ring spot, anthracnose, seedling laying disease.
The amount of application when content of active component depends on independent use in the present composition, also depends on mixed ratio and the synergistic effect degree of a kind of compound and another kind of compound, and the while is also relevant with target disease.Conventionally in composition, the weight percentage of active component is gross weight 2%～90%, is preferably 5%～80%.According to different preparation types, active component content scope is different.Conventionally, liquid preparation contains 1%～60% active substance by weight, is preferably 5%～50%; Solid pharmaceutical preparation contains 5%～80% active substance by weight, is preferably 10%～80%.
In composition pesticide of the present invention, at least contain a kind of surfactant, the dispersion of active component in water while being beneficial to use.Surface-active contents is 2%～30% of total formulation weight amount, and surplus is solid or liquid diluent.
Composition pesticide of the present invention can be by user before use through dilution or directly use.Its preparation can be prepared by processing method known in those skilled in the art, after being about to active component and mixing with liquid flux or solid carrier, then add surfactant as one or more in dispersant, stabilizing agent, wetting agent, binding agent, antifreeze, disintegrant, defoamer etc.
Composition pesticide of the present invention, can be processed into acceptable formulation on any agricultural chemicals on demand.Wherein preferred dosage form is wetting powder, water dispersible granules, suspending agent, suspension emulsion, microemulsion, aqueous emulsion, microcapsule suspending agent, microcapsule suspension-suspending agent, can also make aqua, soluble powder.
