Description
Technical field
What the present invention relates to is a kind of microbicide compositions novel form with synergistic effect; show extremely strong antibiotic and bactericidal activity; be mainly used in control paddy rice, wheat, barley, cotton, soybean, banana, watermelon, peanut, the harm of grape germ; crops are had protective effect and therapeutic action, belong to agricultural plant chemicals technical field.
Background technology
As everyone knows,, seek to reduce the risk that agricultural chemicals and use thereof bring, become the much-talked-about topic of formulation art by the innovation of preparation technique along with pesticide hazards problem and people become increasingly conspicuous to the concern of living environment.Many agricultural chemicals experts point out after looking back the problem that relevant pest resistance to insecticide administers, the skewness of agricultural chemicals be since the operation technique and the formulations of pesticide be not suitable for cause; And emphasize in pesticide resistance comprehensive regulation strategy from now on, must be the formulations of pesticide and technique in using agriculture chemical necessary component as resistance management research.Have research to point out, as the actual dose that is subjected in the pest target, approximately be no more than 6% of field dosage in extensive farmland dispenser process, be no more than 0.1% but most applications is next, greatly part is all missed the target.In view of this, cause the main cause of current agricultural chemicals environmental problem also not exclusively to be to be unfavorable formulation and operation technique to a great extent by agricultural chemicals itself.The factor of technical development simultaneously is to promote the most direct influence factor of pesticide greening purification.Technology such as the suspending agent of developing in recent years, the agent of kind clothing, microcapsule formulations, microemulsion, water dispersible granules are based on the effective way of modern preparation processing technology pesticide greening purification.Suspending agent is in the main trend that reduces consumption of organic solvent, uses and store and transport safe ready, the lasting period is long, the characteristics that do not produce aspects such as " three wastes " in producing have been complied with pesticide greening purification.From above-mentioned meaning, be the water-base preparation of representative with the suspending agent, will become one of important means that solves the pesticide hazards problem.Suspending agent (suspensionconcentration) claim aqueous suspension agent, colloidal suspending agent, concentrated suspension again, is the important formulation of a class of the contemporary farm chemical preparation technology developing direction of representative.Its basic principle is under surfactant and other promoter effects, and former medicine insoluble or that be insoluble in water is distributed in the water, forms uniform and stable thick suspension system.Suspending agent is mainly adjusted agent, defoamer and water etc. by pesticide original medicine, wetting agent, dispersant, thickener, antifreezing agent, pH and is formed.Because its dispersion medium is water, cost is low so suspending agent has, production, storing and characteristics such as safe in utilization, and can mix with arbitrary proportion with water, not influenced by water quality, water temperature, and is easy to use.Compare with the formulations of pesticide that with the organic solvent are medium, have advantages such as the little and poisoning of environmental influence are light.
Difenoconazole and propiconazole all are effective bactericide.Difenoconazole belongs to azoles fungicide; has interior absorption; it is sterol demethylation inhibitor; fungicidal spectrum is wide; leaf surface treatment or seed treatment can improve output and the guaranteed quality of crop, to Ascomycotina, Basidiomycotina with comprise the imperfect fungus, powdery mildew, rest fungus of Alternaria, Ascochyta, the mould genus of tail spore, Colletotrichum, ball seat Pseudomonas, Phoma, Ramularia, Septoria, Venturia and some is planted and passes pathogen lasting protection and therapeutic activity 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.But Difenoconazole and propiconazole all are based on the missible oil formulation in the market, product cost height not only, and drug effect is poor, and has caused serious environmental to pollute and the excess waste of resource in the product use.
Summary of the invention
The purpose of this invention is to provide a kind of microbicide compositions novel form with synergistic effect, solve existing Difenoconazole and propiconazole and all be under the situation based on the missible oil formulation, there is above-mentioned weak point in the use, realization is formulation with the suspending agent, has the microbicide compositions of synergistic effect simultaneously.
Difenoconazole and propiconazole compound, has obvious synergistic effect, enlarged fungicidal spectrum simultaneously, effective to paddy rice, wheat, barley, cotton, soybean, banana, watermelon, peanut, preventing and treating grapevine diseases, surpass Difenoconazole, two missible oil medicaments of propiconazole list usefulness, and do not have cross resistance between the two.
The objective of the invention is to be achieved through the following technical solutions, a kind of microbicide compositions novel form with synergistic effect, it is characterized in that described microbicide compositions novel form is made up of active ingredient Difenoconazole and propiconazole, add auxiliary agent and filler and make suspending agent, the preparation raw materials by weight is: Difenoconazole 10～25%, propiconazole 10～25%, auxiliary agent 3～25%, filler 10～50%.
Auxiliary agent is by dispersion moisture agent 1～15%, antifreeze 2～6%, and thickener 2～10%, defoamer 0.05～3% is formed.Dispersion moisture agent in the suspending agent adopts polyoxyethylene triphenyl phosphorus hydrochlorate, alkylnaphthalene sulfonate, a kind of or mixture in the alkylphenol polyoxyethylene; Antifreeze adopts alcohols, as propane diols, or glycerine, or ethylene glycol; Thickener adopts xanthans or aluminium-magnesium silicate; Defoamer adopts silicone defoaming agent; Filler can adopt water, or white carbon black, or silica-based a kind of or its mixture.
Microbicide compositions preparation technology method with synergistic effect: composition is by said ratio weighing Difenoconazole and propiconazole, according to the product form that will make is suspending agent, and adopt the auxiliary agent and the filler of proprietary prescription, fully mix, after sand mill grinds, mix, promptly obtain finished product, finished product meets the every index request of country to suspending agent.
Microbicide compositions with synergistic effect is used in control paddy rice, wheat, barley, cotton, soybean, banana, watermelon, peanut, all kinds of diseases of grape, to crop safety, cost is low, preventive effect good.Prove that after tested microbicide compositions chemical property of the present invention is stable, synergy is remarkable, and controlling object is shown tangible synergy and complementation.
The advantage of microbicide compositions: 1, these two kinds of combination of active principles are used, and have enlarged fungicidal spectrum.2, have synergistic effect, through test determination: Difenoconazole, propiconazole use the inhibition correlation coefficient (SR of Rhizoctonia solani Kuhn separately
