Technical field

The present invention relates to a kind of microbicide compositions more particularly to a kind of antimicrobial combinations for wheat powdery mildew prevention and treatment Object.

Background technique

Currently, wheat powdery mildew (Blumeriagraminisf.sp.tritici) is a kind of worldwide disease, each small Wheat main producing region is distributed, and powdery mildew is a kind of fungal disease as caused by powdery mildew, powdery mildew main harm plant leaf blade, The positions such as stalk and petiole (sheath) can be endangered when serious, just when morbidity, there is the white dot of 1~1.5mm in blade face, after gradually expand Greatly subcircular to oval white mildew, mildew surface has one layer of white powder, meets external force or vibration is dispersed immediately.Later period disease portion Mould layer becomes canescence to light brown, and scattered on scab to have pinhead-sized small black grain point, the disease is very big to yield effect, causes Biggish economic loss.Prevention and treatment wheat powdery mildew mainly uses the ingredients such as triazolone, Tebuconazole, kresoxim-methyl at present, but generally existing The problems such as resistance is fast, and preventive effect reduces.

Summary of the invention

For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of killing for wheat powdery mildew prevention and treatment Chlorobromide isocyanuric acid and fluorine chlorine ether bacterium azoles are used in compounding by antimicrobial composition, improve preventive effect, reduce Pesticide use amount, are reduced Production cost alleviates the pollution to environment.

The purpose of the present invention adopts the following technical scheme that realization:

A kind of microbicide compositions for wheat powdery mildew prevention and treatment, the active constituent of the microbicide compositions are chlorine bromine Isocyanuric acid and fluorine chlorine ether bacterium azoles, the parts by weight of the active constituent are as follows: 10-50 parts of chlorobromide isocyanuric acid, fluorine chlorine ether bacterium azoles 2- 10 parts.

Chlorobromide isocyanuric acid, english common name: chloroisobromine cyanuric acid is sprayed in crop table Face can discharge hypobromous acid (HOBr) and hypochlorous acid (HOCl) at leisure, there is the strong ability for killing bacterium, fungi and virus.Separately Outside, because starting material is rich in sylvite and microelement group, therefore, chlorobromide isocyanuric acid not only has strong prevention and kills true The ability of bacterium, bacterium and virus, and have the effects of promoting crop nutrient growth, it is suitable for the various crops such as wheat, vegetables.

Fluorine chlorine ether bacterium azoles (Mefentrifluconazole) is a kind of completely new mechanism of action triazole bactericidal agent, is had wide Spectrum, efficiently, interior suction, root out and protective effect, belong to sterol demethylation inhibitor class, the mechanism of action be prevention ergosterol Biosynthesis inhibits cell to grow and eventually lead to the collapsing of cell membrane.Unlike widely used triazole bactericidal agent, Fluorine chlorine ether bacterium azoles, which contains isopropanol structure, can allow it to extremely flexibly rotate freely from free state to be combined into target Reference state, flexible and changeable spatial shape make fluorine chlorine ether bacterium azoles remain efficient to multiple resistance bacterial strain, it is possible to reduce disease Opportunistic pathogen mutation, delays the drug resistance of pathogen.

Further, the dosage form of the microbicide compositions is wettable powder, water dispersible granules, suspending agent, microemulsion One of.

It further, further include following component: wetting agent 5- when the dosage form of the microbicide compositions is wettable powder 10 parts, 5-10 parts of dispersing agent, 20-30 parts of inert filler.

It further, further include following component: wetting agent 5- when the dosage form of the microbicide compositions is water dispersible granules 10 parts, 10-15 parts of dispersing agent, 40-50 parts of inert filler, 5-10 parts of solvent.

It further, further include following component: dispersing agent 5-10 when the dosage form of the microbicide compositions is suspending agent Part, 1-5 parts of emulsifier, 1-5 parts of thickener, 0.01-0.02 parts of defoaming agent, 1-5 parts of antifreezing agent, 45-50 parts of deionized water.

It further, further include following component: emulsifier 15-20 when the dosage form of the microbicide compositions is microemulsion Part, 25-30 parts of solvent, 45-50 parts of deionized water.

Further, the wetting agent is selected from lauryl sodium sulfate, calcium dodecyl benzene sulfonate, octylphenol polyethylene ethylene oxide Base ether sulfate, pull open powder, pungent (nonyl) base phenol polyethenoxy base ether, sldium lauryl sulfate, silkworm excrement, Tea Saponin, alkyl naphthalene sulfonic acid One of sodium is a variety of.
