Description
Technical field:
The present invention relates to a kind of bactericidal composition and application thereof, particularly to a kind of bactericidal composition containing prothioconazoles and benzene metsulfovax and application thereof.
Background technology:
Prothioconazoles (Prothioconazole), it it is the New-type wide-spectrum triazolinthione series bactericidal agent developed by Beyer Co., Ltd, chemical name: 2-(2-(1-chlorine cyclopropyl)-3-(2-chlorphenyl)-2-hydroxypropyl-1-2-dihydro-3-1,2,4-triazole-3-sulfo-, molecular formula: C14H15Cl2N3OS.Structural formula is as follows:
The mechanism of action of prothioconazoles is to suppress the demethylation effect on the precursor lanosterol of sterol in fungus or the liquor-saturated l4 position of 24-methylene dihydro Mi hair, i.e. demethylation inhibitors (DMIs).Not only there is good systemic activity, excellent protection, treat and root out activity, and the lasting period is long.By substantial amounts of field control effectiveness test, result shows that crop is not only had good safety by prothioconazoles, and preventing disease theraping effect is good, and increases production substantially, compares with triazole type biocide agent, and prothioconazoles has broader spectrum of bactericidal activity.It is mainly used in numerous diseases such as preventing and treating cereal crop such as Semen Tritici aestivi, Fructus Hordei Vulgaris, Brassica campestris L, Semen arachidis hypogaeae, Oryza sativa L. and legume crop.Almost all wheat and barley diseases there is good prevention effect, such as Semen Tritici aestivi and the powdery mildew of Fructus Hordei Vulgaris, banded sclerotial blight, droop, leaf spot, rust, sclerotiniose, net blotch, moire disease etc..Oil Lay and the soil-borne disease of Semen arachidis hypogaeae can also be prevented and treated, such as sclerotiniose, and main foliage disease, such as gray mold, melasma, brown spot, balck shank, sclerotiniose and rust etc..
Benzene metsulfovax (Benthiavalicarb-isopropyl), chemical name: [[(6-fluoro benzothiazole-2-base)-ethylaminocarbonyl]-2-methyl-propyl] carbamic acid isopropyl ester.
Benzene metsulfovax is the new type bactericide one benzene metsulfovax developed jointly by combinatorial chemistry industrial group and Ihara company, phytophthora root rot is had good bactericidal activity, to its sporangial formation, sporangial sprouting, there is good inhibiting effect at low concentrations, but the release of zoospore and the movement of zoospore are not acted on.Field test to Plasmopara viticola, downy mildew of cucurbits bacterium and Cruciferae Pseudoperonospora cubensis, result is similar.The late blight of potato and downy mildew of cucurbits are had bactericidal activity by benzene metsulfovax.
The industrial crops cultivated areas such as the difficulty of prevention and cure of current phytopathogen is increasing, on the one hand, along with the change of pattern of farming, melon fruits and vegetables progressively expand, and disease occurrence degree, occur quantity all to increase, and in preventing and treating, difficulty strengthens；On the other hand, the resistance of pathogen rises year by year under lasting medicament selection pressure, and the prevention effect of single dose is had a greatly reduced quality, and control of plant disease is faced with significant challenge.
Summary of the invention:
It is an object of the invention to provide a kind of applied widely, plant bactericide drug compositions containing prothioconazoles and benzene metsulfovax that cost is low, effective for above-mentioned technical problem.
It is a still further object of the present invention to provide a kind of bactericidal composition containing prothioconazoles and benzene metsulfovax and cause the application of fungal disease medicine as preparation preventing and treating plant epiphyte, prevent and treat the application of medicine in powdery mildew, banded sclerotial blight, droop, leaf spot, rust, sclerotiniose, net blotch, moire disease, gray mold, melasma, brown spot, balck shank, downy mildew, smut and late blight especially as preparation.
It is an object of the invention to be realized by following measures:
A kind of bactericidal composition containing prothioconazoles and benzene metsulfovax, wherein prothioconazoles and benzene metsulfovax weight ratio are 1～70:1～50, it is preferred to 1～35:1～25, more preferably 1～10:1～20, it is most preferred that for 1:2～6.
It is 2～80% that both described prothioconazoles and benzene metsulfovax account for the percentage by weight of compositions, it is preferable that 10～40%.
The dosage form that described prothioconazoles and benzene metsulfovax and known auxiliary agent and excipient are re-dubbed on pesticide to allow.These known auxiliary agents have dispersant, diffusant, defoamer, wetting agent, disintegrating agent etc., calcium dodecyl benzene sulfonate can be adopted, alkylphenol polyoxyethylene, Ben-zylphenol Polyoxyethyl Ether, phenethyl phenol polyethenoxy ether, fatty alcohol-polyoxyethylene ether and similar products thereof, aliphatic amine polyoxyethylene ether, fatty acid ethylene oxide addition product, polyoxyethylene polyoxy propylene ether, castor oil polyoxyethylene ether, NPE, TWEEN Series, fatty alcohol-polyoxyethylene ether, Polyethylene Glycol series, Sulfonates, carboxylate, sulfate, phosphate, phosphite, lignosulfonates, xanthan gum, phenol formaldehyde condensate, ammonium salt, quaternary etc., excipient includes Ketohexamethylene, dimethylbenzene, various solvent naphthas, water, antifreezing agent (such as propylene glycol), deionized water etc..Above auxiliary agent, excipient and other adjuvant can be alone or and use.
Described dosage form is cream, wettable powder, suspending agent, aqueous emulsion, microemulsion or water dispersion granule.
The described bactericidal composition containing prothioconazoles and benzene metsulfovax is as the application of preparation preventing and treating resistance plant fungal disease medicine.
The described bactericidal composition containing prothioconazoles and benzene metsulfovax prevents and treats the application of powdery mildew, banded sclerotial blight, droop, leaf spot, rust, sclerotiniose, net blotch, moire disease, gray mold, melasma, brown spot, balck shank and smut medicine as preparation.
Beneficial effects of the present invention:
Bactericidal composition of the present invention is as the application of medicine on preparation preventing and treating resistance plant fungus, and the application preventing and treating powdery mildew, banded sclerotial blight, droop, leaf spot, rust, sclerotiniose, net blotch, moire disease, gray mold, melasma, brown spot, balck shank, downy mildew, late blight and smut medicine especially as preparation all has significant effect.Bactericidal composition of the present invention can produce higher synergistic function, and activity is more than the activity of independent component.
Compared with prior art beneficial effects of the present invention: (1) is compared with single dose, bactericidal composition antagonism fungal disease such as powdery mildew, banded sclerotial blight, droop, leaf spot, rust, sclerotiniose, net blotch, moire disease, gray mold, melasma, brown spot, balck shank, downy mildew, late blight and smut of the present invention have obvious synergistic function, delay Drug resistance, expanding prevention is composed, hence it is evident that improve prevention effect；(2) preventing and treating recruitment, drug cost are reduced；(3) alternative routine and the pesticide being easily generated resistance；(4) compared with single dose, produce and use cost reduces；(5) suppressing the drug-fast generation of fungus, its effect uses apparently higher than its single dose.
