Description

A kind of bactericidal composition containing prothioconazoles and fluopicolide and application thereof
Technical field:
The present invention relates to a kind of bactericidal composition and application thereof, especially a kind of with prothioconazoles and fluopicolide be main active bactericidal composition and application.
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..
Fluopicolide (Fluopicolide), molecular formula: C14H8Cl3F3N2O.The chloro-N-{ of chemical name: 2,6-bis-[3-chloro-5-(trifluoromethyl)-2-pyridine] methyl } Benzoylamide.Structural formula:
Fluopicolide is the new pyridine acid amide fungicides with its particular mechanism developed by Beyer Co., Ltd.It is mainly used in preventing and treating oomycetes diseases such as downy mildew, epidemic disease etc., in addition also rice blast, gray mold, powdery mildew etc. is had certain preventive effect, with other compounds no interactions resistances.
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 bactericidal composition containing prothioconazoles Yu fluopicolide that cost is low, effective for above-mentioned technical problem.
It is a still further object of the present invention to provide this bactericidal composition and cause the application of fungal disease medicine as preparation preventing and treating plant epiphyte, prevent and treat the application of powdery mildew, banded sclerotial blight, droop, leaf spot, rust, sclerotiniose, net blotch, moire disease, gray mold, melasma, brown spot, balck shank, rice blast and epidemic disease medicine especially as preparation.
It is an object of the invention to be realized by following measures:
A kind of bactericidal composition containing prothioconazoles and fluopicolide, described prothioconazoles and fluopicolide 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.
In the compositions of the present invention, the percentage by weight accounting for compositions both prothioconazoles and fluopicolide is 2~80%, it is preferable that 10~40%.
Described bactericidal composition, the dosage form that wherein prothioconazoles and fluopicolide 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 block compound, 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, one or more mixing in 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 bactericidal composition, its dosage form is cream, wettable powder, suspending agent, aqueous emulsion, microemulsion or water dispersion granule.
The described bactericidal composition containing prothioconazoles and fluopicolide has the application of preventing and treating resistance plant fungal disease medicine as preparation.
The described bactericidal composition containing prothioconazoles and fluopicolide 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, rice blast and epidemic disease medicine as preparation.
Beneficial effects of the present invention:
Compared with prior art beneficial effects of the present invention: (1) is compared with single dose, said 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, rice blast and epidemic disease have obvious synergistic function, overcome and delayed 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.
