Abstract
The invention relates to a pesticide missible oil preparation which comprises a pesticide active constituent, an emulsifying agent, a cosolvent and a solvent, wherein the solvent is glycerol; a TG-2201 emulsifying agent is preferably selected as the emulsifying agent; absolute ethyl alcohol is preferably selected as the cosolvent; the pesticide active constituent is a compound of abamectin and high-efficiency cypermethrin, a compound of chlorpyrifos and the high-efficiency cypermethrin, or a compound of fenvalerate and synergistic phosphorus. Because the glycerol is used for replacing toluene and dimethylbenzene of a traditional solvent, the active drug effect of the pesticide missible oil preparation is better than that of a missible oil preparation using the toluene or the dimethylbenzene as a solvent, and moreover, the replacement application of the glycerol used as the solvent solves the problem of toxic and side effects generated by using a large quantity of the toluene and the dimethylbenzene, thus the pesticide missible oil preparation belongs to a green environmental-friendly novel pesticide.
Description
Technical field:
The present invention relates to a kind of farm chemical emulsion preparation, particularly relate to glycerine and replace toluene or dimethylbenzene to make the farm chemical emulsion preparation of solvent.
Background technology:
At present, the solvent that uses in farm chemical emulsion preparation mainly is toluene and dimethylbenzene, but a large amount of uses of toluene and dimethylbenzene have produced many problems, for example toluene and dimethylbenzene have excitant to skin, mucous membrane, central nervous system there is anesthetic effect, suck that higher concentration can go out to lose face and the obvious stimulation symptom of the upper respiratory tract in short time, and toluene, dimethylbenzene dissolubility in water are little, therefore floatability or be oily and be distributed in the water surface, cause fish and other aquatile death, cause environmental pollution.In addition, toluene and dimethylbenzene also have stronger volatility and inflammability, have potential safety hazard in transportation and use.
Because traditional medication custom, toluene, dimethylbenzene is done the still extensive use of cream preparation of solvent, this mainly is because cream preparation is better than other preparation such as wetting powder etc. aspect drug effect, though at control some special insect such as scale insects, aspects such as aleyrodid are better than other formulation, and it also is better than formulations such as water dispersible granules aspect cost, but because toluene in the missible oil, dimethylbenzene is to the pollution of environment with to the harm of human and livestock health, country has stopped the registration to this class emulsifiable concentrate pesticide, be the farm chemical emulsion preparation medication environment of the friendly type of create environment, the research and development green solvent replaces toluene in the missible oil, dimethylbenzene has great importance.
Summary of the invention:
The object of the present invention is to provide a kind of replace toluene, dimethylbenzene as solvent and can reduce environmental pollution or/and alleviate environment-protection pesticide cream preparation to human and livestock health harm.
The applicant is through discovering in a large number, and it is the cream preparation of solvent that the active drug effect of missible oil of making solvent with glycerine is better than with toluene or dimethylbenzene, and glycerine has solved the toxic and side effect of using generation because of toluene, dimethylbenzene in a large number as the alternate application of solvent.Based on above-mentioned discovery, the applicant has finished the present invention.
The application of glycerine on agricultural seldom.Glycerine has another name called glycerine, as industrial chemicals, is used to make synthetic resin, plastics, paint, monobel, grease and beeswax etc. in a large number, also is used for industry such as pharmacy, spices, cosmetics, amenities.Glycerine, be a kind of colourless, do not have a sweet thick liquid of smelling, distinguish the flavor of.But the report that does not also have glycerine in agricultural chemicals, to use at present.
Glycerine of the present invention is a colourless viscous liquid, and odorlessness has warm sweet taste; Fusing point (℃): 18.18; Boiling point (℃): 290.9; Viscosity (20 ℃): 1412mPa.s, (25 ℃): 945mPa.s; Flash-point (℃): 177, flash-point is low; Health hazard: edible nontoxic to human body.Eyes, skin do not had spread effect; Mouse oral toxicity LD50=31500mg/kg.Intravenously administrable LD50=7560mg/kg.Can be miscible in ethanol, miscible with water, some inorganic matter of solubilized.Because it is nonpoisonous and tasteless nuisanceless, be used for the best substitute of cosmetics/food industry for diethylene glycol (DEG)/ethylene glycol.
Farm chemical emulsion preparation of the present invention comprises pesticide activity component, emulsifier, cosolvent and solvent.Wherein, used solvent is a glycerine, and pesticide activity component is that in Avermectin, methyl A Wei salt, chlopyrifos, Acetamiprid, cypermethrin, beta-cypermethrin, brofluthrinate, cyfloxylate, fenpropathrin, sumicidin, alkynes mite spy, butyl ether urea, flufenoxuron, Buprofezin and the azacyclotin one or more are composite.
The present invention, the preferred TG-2201 emulsifier of described emulsifier, the preferred absolute ethyl alcohol of cosolvent.
The present invention, owing to use glycerine to replace traditional solvent toluene and dimethylbenzene, select for use TG-2201 emulsifier and absolute ethyl alcohol as cosolvent simultaneously, it is the cream preparation of solvent that its active drug effect not only is better than with toluene or dimethylbenzene, and glycerine solved the toxic and side effect of using generation because of toluene, dimethylbenzene in a large number as the alternate application of solvent, belongs to the environmental protection novel agrochemical.
