Abstract
Disclosed is a compound azoxystrobin aqueous emulsion, which belongs to the fungicide technique in the crop protection field. The composition of the invention includes: 8-80 percent of azoxystrobin azole, 2-40 percent of emulsifier, 2-10 percent stabilizing agent, 5-8 percent of anti-freeze agent, 1-5 percent of antifoaming agent, 10-20 percent of dissolvant, 10-20 percent of cosolvent and water of residual volume. The invention adopts the preparation method that the aqueous emulsion shall be prepared in an emulsification axe, and has the processing procedure that: firstly, the original drug is mixed with the dissolvant and the cosolvent evenly under the mechanical agitation, then the emulsifier and stabilizing agent are launched into for being evenly agitated, finally water is added in for being agitated for 10-30 minutes under the rotation rate of 100-12000Rpm for getting the uniform and emulsive product. The invention is the new formulation-aqueous emulsion of the azoxystrobin, which overcomes the defects of emulsifiable solution, wettable powder, suspending agent, etc., the aqueous emulsion reduces the use-cost for farmers as well as reducing the environmental pollution, the toxicity of pesticides and cost of products and improving the safety and pesticide effect.
Description
Technical field
What the present invention relates to is a kind of agricultural broad-spectrum germicide azoxystrobin water emulsion and preparation method thereof. particularly a kind of having prevention and treating azoxystrobin water emulsion of double action and preparation method thereof at cucumber downy mildew, lawn fusarium wilt brown spot, early blight of tomato, watermelon anthrax and climing rot or the like development.
Background technology
Fluoxastrobin is a kind of wider bactericide, and main feature is: 1, wide spectrum.All effective to multiple diseases.2, efficient.In current hypotoxicity bactericide Fluoxastrobin be drug effect than higher, in state-owned several families manufacturer production, its product is water dispersible granules.Formulations such as suspending agent, these several formulations are little to the harm of environment, but transportation is inconvenient, stores shortcomings such as inconvenience.This profit dispersiveness of aqueous emulsion as far back as 19th century in early days just the someone begin one's study, but aqueous emulsion because of its stability you be fine, also layering, factors such as the large usage quantity of surfactant, this novel form of also little aqueous emulsion in the conventional pesticide kind so far.The objective of the invention is in order not use or reduce the usage amount of aromatic organic solvent as far as possible; reduce emulsion pollution to environment when using; health with protection environment and user; in addition; owing to replace a large amount of organic solvents with water, improved the safety in production, transportation and the storage process.The present invention proposes aqueous emulsion that uses Fluoxastrobin and preparation method thereof for this reason.
Summary of the invention
The invention provides a kind of azoxystrobin water emulsion and preparation method thereof.
A kind of aqueous emulsion, Fluoxastrobin be as active component, contains that emulsifier 2～40%, stabilizing agent 2～10%, antifreeze 5 parts～8%, defoamer account for 1～5%, solvent 10～20%, cosolvent 10～20% and excess water, more than all be weight percentage.
Emulsifier is one or more in aliphatic alcohol polyoxyvinethene phosphate, alkylphenol polyoxyethylene formaldehyde condensation products, alkylphenol polyoxyethylene, alkyl benzene calcium sulfonate, alkylphenol polyoxyethylene phosphate, the fatty alcohol-polyoxyethylene ether.
Stabilizing agent newspaper is drawn together a kind of in sodium hydrogen phosphate, succinic acid, adipic acid, oxalic acid, the borax
Antifreeze is one or more compositions of ethylene glycol, propane diols, glycerine, urea, ammonium sulfate etc.
Defoamer generally is meant organosilicon.
Solvent is meant that toluene, dimethylbenzene, ethanol, methyl alcohol, propyl alcohol, dimethyl formamide, n-butanol, cyclohexane, isopropyl alcohol, cyclohexanone prop up one or more that the slave does.
Cosolvent is one or more compositions in n-octyl alcohol, n-butanol, ethylene glycol, glycerine, polyethylene glycol, the methyl-sulfoxide.
A kind of Fluoxastrobin is that the preparation method of aqueous emulsion is
1, composition of raw materials: Fluoxastrobin azoles 8～80%, emulsifier 2～40%, stabilizing agent 2～10%, antifreeze 5 parts～8%, defoamer account for 1～5%, solvent 10～20%, cosolvent 10～20% and excess water;
2, preparation method: preparation should be carried out in the emulsification axe, its procedure is: at first former medicine and solvent and cosolvent are mixed under mechanical agitation, drop into emulsifier then and stabilizing agent stirs, add entry at last, under 100～12000 rev/mins rotating speed, stirred 10～30 minutes, and made it to become the product of even emulsus
Advantage of the present invention and good effect are:
1, reduced environmental pollution: aromatic organic solvent content and only contains 5-30% up to 45-60% in the conventional cream preparation in the aqueous emulsion, has reduced the aromatic organic solvent usage amount, thereby has reduced environmental pollution.
2, reduced the toxicity of agricultural chemicals.
3, improved safety:, improved the safety in production/storage and the transportation because water has replaced most of organic solvent.
4, improved drug effect.
