Description

A kind of bactericidal composition

Technical field

The invention belongs to technical field of pesticide, especially fungicide field, and in particular to a kind of sterilization containing polyglutamic acid Composition.

Background technique

Polyglutamic acid is the product of microorganism (predominantly bacillus category) fermentation, is a kind of extracellular polypeptide, is to be at present Only it is only can be polymerize as microorganism obtained from 4 kinds of polymeric amino acids (poly-aspartate, gamma-polyglutamic acid, poly ornithine, One of epsilon-polylysine).A kind of water-soluble high-molecular material of the polyglutamic acid as novel biodegradable has moisturizing, increases The characteristics such as thick, film forming, bonding, nontoxic, water-soluble, biodegradable, are widely used it in pesticide field.

Epoxiconazole is absorbability triazole bactericidal agent, and active constituent epoxiconazole inhibits the synthesis of germ ergosterol, resistance Hinder the formation of germ cell wall, and epoxiconazole molecule has strength compatibility to a kind of fungal enzyme, can more effectively inhibit germ former Fungi.All fourth matter enzymatic activitys of crop can be improved in epoxiconazole, lead to the contraction of fungi haustorium, inhibit germ intrusion.

Hexaconazole is azoles fungicide, and the mechanism of action is sterol methyl inhibitor, destroys and prevent the cell of pathogen The biosynthesis of film important composition ingredient steroid ergosterol thickness, causes cell membrane that cannot be formed, and keeps germ dead, have interior suction, It protects and therapeutic.

Difenoconazole is sterol demethylation inhibitors, inhibits the biosynthesis of cell wall sterol, prevents the life of fungi It is long.The yield and guaranteed quality of crop can be improved in wide sterilization spectrum, foliar treatment or seed treatment.

Tebuconazole is triazole bactericidal agent, inhibits the biosynthesis of the ergosterol of fungi, so that pathogen can not be formed Cell membrane is to kill bacterium.

Tetraconazole is triazole bactericidal agent, and the mechanism of action is sterol demethylation inhibitors, due to having in well Absorption, therefore can promptly be absorbed by plants, and conducted in inside；With good protection and therapeutic activity.Lasting period is longer, Generally at 6 weeks or so.

Flutriafol is triazole bactericidal agent, and the mechanism of action is sterol demethylation inhibitors, and ergosterol can be effectively suppressed Biosynthesis, fungal cell wall can be caused to rupture, to many diseases caused by basidiomycetes and sac fungus have good protection And therapeutic effect, but it is inactive to oomycetes and bacterium.

Cyproconazole is triazole bactericidal agent, and the mechanism of action is to inhibit sterol demethylation, has preventive and therapeutic action.

Penconazole is absorbability triazole bactericidal agent, is sterol demethylation inhibitors, is organized by root of the crop, stem, leaf etc. It absorbs, and conducts upwards.

Flusilazole is triazole bactericidal agent, mainly destroys and prevent the cell membrane important composition ingredient ergosterol of germ Biosynthesis, cause cell membrane that cannot be formed, keep germ dead.The germ of Gammaproteobacteria in antithetical phrase, Basidiomycetes and Fungi Imperfecti Caused disease is effective.

Prothioconazoles are triazole thioketone fungicide, are a kind of demethylation inhibitors.

Propiconazole is interior suction triazole bactericidal agent, can be absorbed by plant roots, stem, and conduction upwards quickly.Main pass through is supported The ergosterol of fungi processed synthesizes, and destroys the physiological action of fungal cell membrane, causes fungi dead.

Nitrile bacterium azoles are absorbability triazole bactericidal agent.Mainly the biosynthesis of the ergosterol of pathogen is risen and inhibits to make With all having preferable control efficiency to sac fungus, basidiomycetes.The agent lasting period is long, to crop safety, there is certain stimulating growth Effect.

So far by polyglutamic acid and azoles fungicide such as epoxiconazole, hexaconazole, difenoconazole, Tebuconazole, tetrafluoro Ether azoles, Flutriafol, Cyproconazole, penconazole, Flusilazole, prothioconazoles, propiconazole, myclobutanil compositional, both at home and abroad there is not yet phase Report is closed, and inventor studies and finds that the two compounding has good synergistic effect in a certain range, prevents and treats disease While, have the function that volume increase.

Summary of the invention

Based on the above situation, the purpose of the present invention is to provide a kind of bactericidal composition and its preparations.The bactericidal composition Prevention and treatment with bactericidal effect is good, stability is good, persistence is good, powdery mildew, brown spot, spot defoliation, line can be effectively prevented Blight, false smut, ring spot, anthrachose of grape, scab, rust, white rot, anthracnose, rust, leaf spot, full rot, sclerotium Disease, snow mold, early blight, black spot, moire disease, smut can be prepared into aqueous suspension agent, wettable powder, water dispersion Granula, granule.

To achieve the purpose of the present invention, the invention provides the following technical scheme:

A kind of bactericidal composition, it is characterised in that the bactericidal composition includes effective constituents A and B, and A is polyglutamic acid, and B is Epoxiconazole, hexaconazole, difenoconazole, Tebuconazole, tetraconazole, Flutriafol, Cyproconazole, penconazole, Flusilazole, rosickyite bacterium The mass ratio of one of azoles, propiconazole, nitrile bacterium azoles, A and B are 1:40~40:1, preferably 1:20~20:1, and sum of the two accounts for The percentage composition of bactericidal composition is 0.1-50%.

In two-spot compound preparation of the invention, other than effective component, the auxiliary agent allowed on pesticide can be also added, to prepare At any one dosage form.It is preferred that being processed into wettable powder, water dispersible granules, granule, aqueous suspension agent.

The insecticides adjuvant includes dispersing agent, wetability, thickener, antifreezing agent, preservative, thickener etc., uses this Auxiliary agent well known to the technical staff of field.

Instant component is reasonable, and effect is good, and its activity and the active simple superposition of bactericidal effect not instead of each component, With significant synergistic effect, to crop safety, there is excellent control efficiency to corps diseases.
