Description
Technical field
The invention belongs to technical field of pesticide, more particularly, relate to a kind of Clodinafop-propargyl microemulsion and preparation method thereof and application method.
Background technology
The chemical name of clodinafop-propargyl (clodinafop-propargyl) is (R)-2-[4-(the fluoro-2-pyridine of the chloro-3-of 5-oxygen base) phenoxy group] propionic acid propargyl ester, structural formula is
it is the new and effective weed killer herbicide of a kind of chirality, fluorine-containing, fragrant phenoxy propionic acid class, is the cereal ground post-emergence herbicide of Ciba-Geigy company exploitation, is mainly used in the annual gramineous weeds such as Control Wild oat, amur foxtail, perennial ryegrass and green foxtail.Trade name is Topic, Celio, top, alkynes oxalic acid etc., and sterling is white crystals body, 59.5 ℃ of fusing points, and relative density is 1.37 (20 ℃), and in water, solvability is 4.0mg/L (20 ℃), and in toluene, acetone and ethanol, solvability is larger.It is relatively stable in acid medium, be hydrolyzed in alkaline medium, is easy to decompose under illumination, is degraded to very soon free acid phenyl and pyridine moiety enters soil and mineralizer in soil, on succession crop without impact.The mechanism of action of clodinafop-propargyl and feature are to suppress the activity of acetyl-CoA carboxylase (ACCase), it is a kind of interior suction conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, phloem conduction, accumulate in the meristematic tissue of plant corpus, suppress acetyl-CoA carboxylase, fatty acid is synthesized to be stopped, the growth division of cell can not normally be carried out, film system is logical to be waited containing fat structural deterioration, finally cause plant dead, research is found to be first hydrolyzed into acid after clodinafop-propargyl class weed killer herbicide enters in plant corpus, and then with sour form performance herbicide effect.In performance, it is little that clodinafop-propargyl weed killer herbicide shows as toxicity; Consumption is few; Drug effect is high; Metabolic capability is strong; Can suppress the growth of multiple weed seed.First Application is in Switzerland, South Africa and Chile, and existing more than 50 country comes into operation at present.
The formulation of clodinafop-propargyl class weed killer herbicide is in the market mainly wetting powder.Wetting powder is mainly the formulations of pesticide that obtain through air-flow crushing by after the mixing such as clodinafop-propargyl, auxiliary agent (surfactant, thickener etc.) and solid packing (kaolin, fine particle calcium carbonate and diatomite).Because the particle of wetting powder is thicker, thereby be in use with larger solid particle, to be attached to the surface of weeds, be difficult for being absorbed by weeds, pesticide active ingredient runs off more, thereby consumption can increase relatively, easily to environment.The air-flow crushing that wetting powder adopts in process simultaneously, can produce airborne dust in process of production, also endangers the producer in the time of contaminated environment.Wetting powder in use also can cause the secondary pollution to environment owing to producing airborne dust simultaneously.For solving these weak points of clodinafop-propargyl wetting powder, China Patent Publication No. CN102428921 A discloses a kind of clodinafop-propargyl water dispersible granules and preparation method thereof.This invention has overcome the problems such as clodinafop-propargyl not environmental protection of wetting powder and dust drift, but the clodinafop-propargyl of preparation is still with graininess use, is difficult for being absorbed by weeds, and availability is not low.Therefore the clodinafop-propargyl weed killer herbicide of researching and developing a kind of emulsus formulation is significant.
Through patent retrieval, Chinese Patent Application No.: 201010151613.7 disclose the patent document of a kind of Clodinafop-propargyl microemulsion and preparation method thereof, and its microemulsion composition according to weight ratio is: clodinafop-propargyl is 1-50%, solvent 1-20%, cosolvent 1-20%, emulsifier 5-30%, water 50-90%.Preparation method is: first by weight percentage solvent, cosolvent and clodinafop-propargyl are uniformly mixed under the rotating speed of 50-200 rev/min, then drop into the emulsifier of proportion requirement, stir again, finally add water to continue to stir 1-2 hour, can become the solution product of homogeneous transparent, this invention efficiency improves the service efficiency of medicament.
China Patent No.: 201310117910.3 disclose a kind of patent document of production method of Clodinafop-propargyl microemulsion, and its composition of raw materials counts by weight percentage: comprise that clodinafop-propargyl 12-18%, solvent 5-10%, cosolvent 22-28%, surfactant 10-15%, surplus are water; By step 1: the mixing of clodinafop-propargyl, solvent, cosolvent; Step 2: the mixing of surfactant and water; Step 3: the mixing of the mixture of step 1 and the mixture of step 2 finally makes finished product Clodinafop-propargyl microemulsion.This invention has the advantages such as technique is simple, reaction condition is gentle, pollution-free waste discharge, good product quality.
But these patents all reckon without the safety issue of clodinafop-propargyl weed killer herbicide to crop, long-term use can be to this season crop and the toxic effect of succession crop, reckon without the storage stability problem of clodinafop-propargyl weed killer herbicide, long-time storage can make the drug effect of clodinafop-propargyl obviously reduce simultaneously; On the other hand, clodinafop-propargyl micro emulsion is a kind of conventional cornfield herbicidal, and serviceability temperature is substantially below 10 ℃, and the low temperature dispersity of preparation and dilution stability are particularly important, and above patent is not yet in effect addressing these problems all.
