Abstract
The invention discloses a fomesafen microemulsion and a preparation method thereof, wherein the fomesafen microemulsion is a new preparation formulation which is novel, efficient, low-toxicity and pollution-free, is safe for human beings and livestock and is not easy to generate drug resistance on weed; the preparation formulation dissolves the fomesafen in organic solvent by utilizing the action of a surface active agent, and the fomesafen is dispersed in water to form the transparent preparation. The prepared fomesafen microemulsion comprises the following components by weight percent: 1-20% of fomesafen, 5-25% surface active agent, 5-15% of latent solvent, 0.01-5% of stabilizing agent, 0.5-5% of synergistic agent, 0.1-5%of penetration promoting agent and the balance of water. The invention has high use ratio of raw materials, simple technology and low production cost and is a novel agricultural weedicide formulation.
Description
Technical field
The present invention relates to a kind of pesticide herbicide, relate in particular to a kind of fomesafen microemulsion and preparation method thereof.
Background technology
Fomesafen (Fomesafen), chemical name: 5-[2-chloro-4-(trifluoromethyl) phenoxy group]-N-(methyl sulphonyl)-2-nitrobenzamide, molecular structural formula:
Fomesafen is the selectivity diphenyl ether herbicide, is mainly used to prevent and kill off soybean field broad leaved weed, as Tong fiber crops, amaranth, lamb's-quarters, Siberian cocklebur, volume stem knotweed, iron amaranth, bur beggar-ticks, black nightshade, kitchen garden etc., grassy weed is had certain inhibitory action.
Because a large amount of and frequent use of chemical synthetic pesticide has caused residue of pesticide, the generation of disease pest and weed resistance.In recent years, in developed countries such as Great Britain and Americas, in the pesticidal preparations to an organic solvent restriction increasingly stringent, some national dimethylbenzene has disabled trend in pesticide solvent, thereby impel the formulations of pesticide to bring in constant renewal in, wherein Water-borne modification is exactly one of important directions of agricultural chemicals development, both can reduce the pollution of agricultural chemicals as the microemulsion of solvent with water, can reduce the cost of pesticide producing again, become a kind of very important formulation in the pesticide manufacturing.
Summary of the invention
The objective of the invention is to disclose a kind of fomesafen microemulsion and preparation method thereof.
Purpose of the present invention is achieved through the following technical solutions: be active component with the fomesafen, effect by emulsifier, and interpolation auxiliary agent, make it be dispersed in the transparent fomesafen microemulsion of formation in the water, be oil-in-water type (W/O) that the content of fomesafen wherein is 1-20%.
Above-mentioned fomesafen microemulsion is made up of following percentage by weight:
Fomesafen 1-20%, surfactant 5-25%,
Cosolvent 5-15%, stabilizing agent 0.01-5%,
Synergist 0.5-5%, short bleeding agent 0.1-5%,
Antifreezing agent 1-4%, water supplies 100%.
Surfactant of the present invention is an aliphatic alcohol sulfate, alkylol polyoxy ethyl ether sodium sulphate, alkylbenzenesulfonate, alkylnaphthalene sulfonate, fatty alcohol ethylene oxide adduct sulfonate, alkylphenol formaldehyde condensation product ethylene oxide adduct sulfonate, aliphatic alcohol polyethenoxy base ether, alkylphenol-polyethenoxy base ether, dehydration sorbic alcohol fatty acid ester, anhydrous sorbitol fat polyoxyethylene groups ether, phenethyl phenol polyethenoxy polyethenoxy ether, alkylphenol formaldehyde condensation product polyoxyethylene groups ether, in the oxirane nonyl phenol condensation product one or more.
Stabilizing agent of the present invention is one or more in 3-chloro-1,2 expoxy propane, butyl glycidyl ether, phenyl glycidyl ether, cresyl glycidyl ether, polyethylene glycol diglycidyl ether, the sodium sorbate.Antifreezing agent is one or more in ethylene glycol, propane diols, glycerine, polyethylene glycol, the sorbierite.
The short bleeding agent of the present invention is azone, Laurocapram.
Cosolvent of the present invention is one or more in methyl alcohol, DMF, dimethylbenzene, cyclohexanone, ethanol, isoamyl alcohol, phenol, acetone, ethyl acetate, the dimethyl sulfoxide (DMSO).
Synergist of the present invention is Butacide, sulfoxide, formaldehyde, castor oil, chlorination fat, one or more in the piperonyl butoxide.
The preparation method of above-mentioned fomesafen microemulsion, it is characterized in that, with former medicine of fomesafen and cosolvent mixing and stirring, proportionally add surfactant, stabilizing agent, synergist, antifreezing agent, short bleeding agent then earlier, stir, fully mix, add deionized water at last, mix, leave standstill, promptly can be made into microemulsion, packing.
The invention provides a kind of novel, efficient, low toxicity, pollution-free, people livestock and poultry safety and weeds are difficult for producing the fomesafen microemulsion of resistance, this formulation is with water section or all replace the microemulsion of the organic solvent in the missible oil.It is by surface-active effect, fomesafen oil is scattered in the transparent preparation of formation in the water equably, add suitable synergist, short bleeding agent and stabilizing agent therein, thereby make the weed killer herbicide product of high-quality and high-efficiency, raw material availability height of the present invention, technology is simple, and production cost is low, is a kind of weed killer herbicide product of novel formulation.
The present invention has following advantage: because of the miniaturization of preparation drop and with water is the result of dispersion medium, thereby has 1. flash-point height, does not burn and does not explode, and produces storage and safe in utilization; 2. environmental pollution is little, to the producer and user and Environmental security; 3. plant there is good penetration, the absorption ratio height, thereby low dosage just can be obtained higher preventive effect; 4. with water matrix, aboundresources, the low packing of product cost is easily; 5 can reduce the peculiar smell of agricultural chemicals greatly, reduce the injury to crop itself.
