Description
Technical field
The present invention relates to a kind of pesticidal preparations, specifically, is aqueous emulsion of a kind of benzene metsulfovax and preparation method thereof.
Background technology
The benzene metsulfovax has excellent bactericidal activity to phytophthora root rot, and the sporangial sprouting of its sporangial formation is had the good restraining effect under low concentration, but to the release of zoospore and the not effect of moving of zoospore.Similar to downy mildew of garpe bacterium (Plasmopara viticola Berl) downy mildew of cucurbits bacterium (Pseudoperonospora cubensis Rostov.) with the field test results of Cruciferae Pseudoperonospora cubensis (Peronospora parasitica Fr.).The biological chemistry action mechanism of benzene metsulfovax just under study for action; The benzene metsulfovax has the phytophthora infestans of resistance and has the downy mildew of cucurbits of resistance that bactericidal activity is all arranged to methoxy acrylic functional group benzamide functional group, infers that the benzene metsulfovax is different with the mechanism of action that contains these functional group's bactericide.And the benzene metsulfovax does not influence the oxidation of nucleic acid and protein and synthesizes, to the not influence of function of phytophthora root rot bacterium protoplasmic membrane.
At present the benzene metsulfovax is main with pulvis, wetting powder, water dispersible granules mainly because and wetting powder, pulvis exist big for environment pollutionly, there are shortcomings such as power consumption of polymer processing height in water dispersible granules.The modern formulations of pesticide are towards water baseization, ultramicronising, no efflorescence and the development of sustained release aspect; Promptly be the formulations of pesticide of matrix with water; Wherein aqueous emulsion be a kind of organic solvent as far as possible few with in addition the novel pesticide formulation of no, good drug efficacy, environmentally-friendly water-basedization, also be a kind of good liquid dosage form that replaces emulsifiable concentrates for agricultural chemicals.
The aqueous emulsion of benzene metsulfovax of the present invention has efficiently, low toxicity, environmentally friendly, person poultry safety, is prone to the characteristics of degraded, compares with traditional missible oil; Greatly reduce production costs; Save a large amount of petrochemical industry resources, and benzene metsulfovax aqueous emulsion of the present invention replaces a large amount of organic solvents with water, generation pollution in avoiding producing, explosive and poisoning problem; Pesticide processing is hanged down poison, ensure human and mammiferous safety and health.
Summary of the invention
The objective of the invention is to overcome the environmental pollution that exists in the prior art, harm is healthy and defective such as manufacturing cost height and a kind of efficient, the low toxicity developed, environmentally friendly, person poultry safety and be prone to the benzene metsulfovax aqueous emulsion producing and use.
Technical scheme of the present invention: for realizing above-mentioned purpose, the present invention provides a kind of benzene metsulfovax aqueous emulsion, and each component is following by weight percentage: benzene metsulfovax: 1-20%; Solvent and cosolvent: 1-45%; Emulsifier: 1-15%; Dispersant: 0.5-2%; Stabilizing agent: 1-5%; Antifreezing agent: 1-5%; Surplus is a deionized water.
Wherein:
Solvent and cosolvent are one or more the mixing of xylol, toluene, isobutanol, ethyl acetate, N-octylpyrrolidone, repefral, diethyl phthalate, dibutyl phthalate, aromatic hydrocarbon solvent Solvesso100, aromatic hydrocarbon solvent Solvesso150, aromatic hydrocarbon solvent Solvesso200.
Emulsifier is one or more the mixing in APES, alkaryl phenol polyethenoxy ether phosphate, castor oil polyoxyethylene ether, alkylbenzenesulfonate, alkylphenol-polyethenoxy phosphate, polyoxyethylene sorbitan fatty acid ketone, sorbitan ester, AEO, maleic acid di-sec-octyl sodium sulfonate, castor oil, the lauryl sodium sulfate.
Dispersant is an alkyl phenol formaldehyde resin polyoxyethylene ether sulphate.
Stabilizing agent is one or more the mixing in peanut oil, antioxidant 264, epoxidized soybean oil, epoxy linseed oil, epoxy fat, pentaerythrite, xylitol, the pyrogallic acid.
Antifreezing agent is one or more the mixing in ethylene glycol, propane diols, glycerine, the diethylene glycol.
Benzene metsulfovax method for producing aqueous emulsion provided by the invention is: the benzene metsulfovax is dissolved in solvent and the cosolvent, adds emulsifier, stabilizing agent and dispersant again, make oil phase; Antifreezing agent mixed obtaining water with deionized water, under shear conditions, oil phase is slowly joined aqueous phase or water is slowly joined in the oil phase, make benzene metsulfovax aqueous emulsion.
Compared with prior art, benzene metsulfovax aqueous emulsion provided by the invention is as a kind of water base chemical preparation, has efficient, low toxicity, environmentally friendly, person poultry safety, and characteristics such as be difficult for developing immunity to drugs.Adopt the solvent and the emulsifier of low toxicity, stable performance is prone to degraded, and active high to corps diseases, environmental pollution is very little.The technological process of production is simple, and the investment of production equipment expense is low, is easy to processing.
Benzene metsulfovax aqueous emulsion provided by the invention has following advantage:
1, benzene metsulfovax aqueous emulsion provided by the invention substitutes most organic solvent with deionized water, reduces environmental pollution, helps ecological environmental protection; Also can reduce production costs greatly, save a large amount of petrochemical industry resources, and adopt the solvent of low toxicity; Significantly reduce organic solvent to the pollution of human body and environment and residual; Produce pollution, explosive and poisoning problem in avoiding producing, make pesticide processing produce low poisoning, ensure people and animals' safety and health.
2, benzene metsulfovax aqueous emulsion provided by the invention not only has crop and well adheres to and permeability, and properties of product are stable, and activity is higher, has improved drug effect, reduces the dosage of medicament simultaneously.
