Abstract
The invention discloses a bactericide composition. The bactericide composition is characterized by containing two active ingredients difenoconazole and propiconazol, wherein the weight ratio of the difenoconazole to the propiconazol is 1:2 to 2:1; and the composition contains 20 to 40 weight percent of active ingredients difenoconazole and propiconazol, and belongs to a systemic triazole bactericide with protection and control functions. The bactericide composition has the dual effects of preventing and controlling diseases and insects and adjusting the growth of crops, high systemic activity, broad spectrum and relatively longer persistence, and can reduce the cost of pesticide prevention and control, improve prevention and control effects and be widely applied to the prevention and control of middle-later diseases and insects of rice, in particular to the prevention and control of rice sheath blight.
Description
Technical field
The present invention relates to a kind of microbicide compositions of broad spectrum activity, relate in particular to a kind of composition that contains a kind of bactericide of Difenoconazole and two kinds of active ingredients of propiconazole.
Background technology
Difenoconazole belongs to interior absorption sterilization, tool protection and therapeutic action.Fungicidal spectrum is wide, and blade face or seed treatment can improve output and the guaranteed quality of crop.To Ascomycetes, Basidiomycetes and comprise Alternaria, Ascochyta, the mould genus of tail spore, Colletotrichum, ball Cuo Pseudomonas, Phoma, Ramularia, Septoria, Venturia partly know disease, Erysiphaceae, Uredinales and some are planted and are passed pathogen lasting protection and therapeutic action are arranged.
Propiconazole is a kind of interior absorption triazole bactericidal agent 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; particularly to take-all, powdery mildew, rust, root rot, water rice bakanae disease, sigatoka have the better prevention effect.
Though above-mentioned Difenoconazole and propiconazole all have the advantage of control plant pest, when folk prescription uses, the drug effect limitation, and can not prevent and treat rice sheath blight disease.
Rice sheath blight disease is one of important disease of generally taking place of paddy rice producing region in the world, and each rice district of China falls ill in rising trend from recent years.Present and rice blast, bacterial leaf-blight constitute the three big diseases of paddy rice.In recent years because paddy rice continuous cropping area is big, planting density strengthens, and disease is only second to rice blast.Banded sclerotial blight can make the plants stems stalk, leaf sheath is withered causes that to rotting ripening rate descends, and thousand kernel weight reduces, even plant lodging (and having no harvest).
Rice sheath blight disease generally begins morbidity latter stage at rice tillering, and circle stalk jointing is contained to heading stage and sent out.The serious field piece of falling ill, rice leaf and mycelia tied up in knots, rice straw is softer, and it is withered very easily to lodge, very big to yield effect.
Summary of the invention
The present invention is a kind of composition and the application thereof that contains a kind of bactericide of Difenoconazole and two kinds of active ingredients of propiconazole that provides for the above-mentioned shortcoming that overcomes the prior art existence, the present invention has strong interior absorption, broad spectrum activity and longer lasting effect, be widely used in preventing and treating paddy rice middle and later periods disease, especially the control of rice sheath blight disease.
To achieve these goals, the invention provides a kind of microbicide compositions, be characterized in that contain two kinds of effective active compositions of Difenoconazole and propiconazole, the weight ratio of described Difenoconazole and two kinds of effective active compositions of propiconazole is between 1: 2～2: 1.
Above-mentioned a kind of microbicide compositions, wherein, the gross weight percentage composition of active component Difenoconazole and propiconazole is between 20%～40% in the described composition.
Above-mentioned a kind of microbicide compositions, wherein, best proportioning is that the gross weight percentage composition of Difenoconazole and propiconazole is 30%.
Above-mentioned a kind of microbicide compositions, wherein, the weight ratio of described Difenoconazole and two kinds of effective active compositions of propiconazole is 1: 1.
The present invention is owing to adopted above technical scheme, and the technique effect of its generation is tangible:
1, the complex preparation of Difenoconazole and propiconazole belongs to a kind of new and effective bactericide, utilizes the effect characteristics of two kinds of bactericide, has disease of preventing and treating and the double action of regulating plant growth.
2, the combination of Difenoconazole and propiconazole is a kind of interior absorption triazole bactericidal agent with protection and therapeutic action, and by interior suction conduction, it is wide to show as fungicidal spectrum.Can be absorbed by the root of plant, stem, leaf portion, and can in plant corpus, conduct very soon, can prevent and treat the control of the disease that most of higher fungies cause, especially rice sheath blight disease effectively to the top.
Embodiment
The present invention adopts Difenoconazole and propiconazole compound mode, prepare a kind of microbicide compositions, this microbicide compositions contains Difenoconazole and two kinds of effective active compositions of propiconazole, and the weight ratio of described Difenoconazole and two kinds of effective active compositions of propiconazole is between 1: 2～2: 1.In the described composition between the weight percent gross weight 20%～40% of active component Difenoconazole and propiconazole.Make product by preparation suspension emulsion SE method, be mainly used in the control of rice disease, especially the control of rice sheath blight disease.
Below further specify feature of the present invention and performance by several embodiment.
The complex preparation total content of Difenoconazole and propiconazole is between 20%～40% in the embodiments of the invention, and weight ratio is between 1: 2～2: 1.
The present invention can make suspension emulsion SE with Difenoconazole and propiconazole compound, or other formulations: but as wet-milling WP, water dispersible granules WDG, missible oil EC, aqueous emulsion EW, microcapsule suspending agent CS etc.The preferred suspension emulsion SE of the present invention.So-called suspension emulsion SE is a kind of formulation that the pesticide activity component of several different physical aspects is re-dubbed.In the present embodiment, be with the liquid condition of propiconazole and the solid state of Difenoconazole, and be that medium is processed into stable outstanding newborn dispersion with water.By selecting the formulation form of suspension emulsion, can effectively reduce the usage amount of organic solvent in the conventional formulation, reach the composite purpose with the formulation environmental protection of preparation.
The field efficacy result of the present composition:
