Abstract
The invention discloses a tebufenpyrad pesticide effect-enhancing water emulsion. The water emulsion is characterized by comprising the following components by weight percent: 10-25% of tebufenpyrad active compound, 1-10% of synergist, 1-20% of emulsifying agent, 1-5% of antifreeze agent, 0-2% of defoaming agent, 1-45% of solvent, 0.1-3% of thickening agent and the balance of water. According to tebufenpyrad pesticide effect-enhancing water emulsion, a large amount of water is taken as the solvent, so that the water emulsion is safe, green and environment-friendly, and is the inexorable trend of the pesticide preparation in 21 century, the conventional mode that the pesticide effect is improved by compounding the pesticide with other conventional pesticides is abandoned, and the special synergist is adopted, so that the effect-enhancing function of the pesticide is improved greatly without increasing the using amount of the pesticide, the cost is saved, the pesticide effect is enhanced, the pesticide residual is lowered, and the environment is protected effectively.
Description
Technical field
The present invention relates to the preparation method of a kind of many phenyl ring polyethers succinate and sulfonate thereof, belong to agricultural chemicals configuration and preparing technical field.
Background technology
Tebufenpyrad be Mitsubishi change into company development, with the pyrazoles miticide (trade name: Pyranica, heart mite Garrick) of cyanamide company joint development, has wide spectrum and quick-acting, application abroad is wider, various formulations are also arranged, but be not promoted in China, if a kind of cry must the mite Garrick the wettable powder commodity obtained registration.
Tebufenpyrad molecular formula: C18H24ClN3O molecular weight: 333.8 CAS accession number: 119168-77-3, chemical name: N-(4-tertiary butyl benzyl)-4-chloro-3-ethyl-1-methyl-5-BEEP azoles formamide, physicochemical property: sterling is white crystals, fusing point 61-62 ℃, vapour pressure 0.010787mPa(40 ℃), solvability: water 2.8mg/L(25 ℃), be dissolved in the majority of organic solvents such as acetone, methyl alcohol, chloroform, acetonitrile, n-hexane and benzene, stability: pH is 3-11, when temperature is 37 ℃, can stablizes for 4 weeks in water.
Tebufenpyrad belongs to the amide-type miticide, various mite classes and Semiptera, homoptera pest had tall and erect effect, and the mite class is all had immediate effect with efficient each vegetative period, lasting period is long, such as Tetranychidae (panonychus ulmi, citrus red mite, cotton spider mites, Tetranychus cinnabarinus etc.), Tarsonemidae (the many tarsonemids of side), Eriophyidae (thorn apple rust mite, grape rust mite etc.), Tenuipalpidae (grape brevipalpus), Aphidiadae (black peach aphid, cotten aphid, apple aphid), Aleyrodidae (cassava aleyrodid).And with dicofol, fenbutatin oxide, thiazole mite ketone etc. without cross resistance, though without interior absorption, osmotically active is arranged, target crop is had splendid selectivity, under the recommended dose (25～200mg (a.i.)/L) to most of crops without poisoning.
The preparation of domestic present appearance only has wetting powder single dose form, and tebufenpyrad and other agricultural chemicals, research report such as the several formulations of the agriculture chemical compoundings such as cinerins, pyridaben is more, such as 11% tebufenpyrad and cypermethrin, the aqueous emulsion that high chlorine is composite, 21% tebufenpyrad fenpropathrin milk oil, tracing it to its cause is because the tebufenpyrad drug effect is not easy to give full play to, need the composite of many kinds, could effectively reach the purpose of Insecticiding-miticiding.Such compounded combination often needs to waste a large amount of agricultural chemicals, has strengthened residue of pesticide, and environment is damaged.At present, the Multiple Pesticides synergist appears on the market, in the agricultural chemicals use procedure, mix into use through bucket, under the guidance that does not have professional knowledge, be easy to cause following consequence: the one,, the synergist improper use meeting that adds destroys the stable of original preparation itself, reduced on the contrary the drug effect of preparation, the 2nd,, produce poisoning.This just requires in the production process of tebufenpyrad preparation, need to pass through repetition test, find a kind of appropriate prescription, optimization by one or more synergist is composite, prepare through the time stable, can give full play to the preparation of drug effect, reach maximized control efficiency with minimum pesticide dosage.
Summary of the invention
In order to overcome the deficiencies in the prior art: the object of the present invention is to provide a kind of through the time stable, can give full play to tebufenpyrad pesticide synergistic aqueous emulsion of drug effect and preparation method thereof.
