Abstract
The haloxyfop-methyl micro emulsion consists of haloxyfop-methyl 5-20 wt%, emulsifier 5-40 wt%, co-solvent 0-10 wt%, antifreezing agent 0-10 wt% and water 10-80 wt%. The herbicide is used in cropland of rape, soybean, etc. to prevent and kill annual and perennial gramineous weeds effectively. It has the advantages of obvious herbicidal effect, safety to human body and animal, environment friendship, low cost, etc.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of microemulsion and preparation method thereof of haloxyfop-methyl with as herbicide applications.
Background technology
Haloxyfop-methyl (haloxyfop-R-methyl), its molecular structure is:
The former medicine of haloxyfop-methyl is a liquid, light fragranced, density 1.372 gram per centimeters
3, boiling point＞280 ℃, distribution coefficient K
OwLog P=4.00 (20 ℃).Henry constant 1.1 * 10
-3Pa m
3Mol
-1Solvability 9.08mg/L in the water in the time of 25 ℃; Solvability in the organic solvent in the time of 20 ℃: acetone, carrene, dimethylbenzene, toluene, methyl alcohol, cyclohexanone all＞1Kg/L.Aqueous solution DT
50(20 ℃) are 100d (PH5), 48d (PH7), 52d (PH9).
Haloxyfop-methyl is a kind of selectivity herbicide after seedling, it is by suppressing acetyl-CoA carboxylase in the plant corpus, cause the fatty acid biosynthesis block to kill weeds, be mainly used in crop Tanakas' such as preventing and kill off rape, soybean, cotton, peanut, beet, tobacco annual and perennial grassy weed such as wild oat, barnyard grass grass, lady's-grass, green foxtail, eleusine indica, wild broomcorn millet, annual bluegrass, moleplant seed, amur foxtail, perennial ryegrass, downy brome, Hordeum, quackgrass, reed, Bermuda grass, false Chinese sorghum.
At present, haloxyfop-methyl has obtained promoting widely and using at home, and particularly as herbicide used in rape field, its consumption surpasses 50%.The formulation that haloxyfop-methyl is sold at home at present and used is 10.8% missible oil.Haloxyfop-methyl missible oil is owing to will add organic chemistry solvents such as a large amount of toluene or dimethylbenzene man-hour adding, these solvents have also entered in the surrounding enviroment such as soil, crops, underground water and atmosphere when using in the farmland, very easily cause soil compaction, lose fertilizer, also might cause people, animal contact back to poison, thereby chemical nuisance residual quantity exceed standard and influence the healthy and safe of people and animals in the food agricultural produce that is processed to form after also might causing in addition.In a word, a large amount of uses of haloxyfop-methyl missible oil might bring severe contamination to ecotope, cause various adverse consequencess.Because in recent years, oil appreciates significantly, causes the price rising all the way of organic solvent, causes the production cost of cream preparation constantly to rise simultaneously, and original low this advantage of farming is all gone.
Summary of the invention
Purpose of the present invention just is to overcome the above-mentioned shortcoming of current haloxyfop-methyl missible oil, thereby a kind of safety and environmental protection is provided and the haloxyfop-methyl micro emulsion of cost advantage is arranged again.
Another object of the present invention is to provide the preparation method of haloxyfop-methyl micro emulsion.
Another purpose of the present invention is to provide the application of haloxyfop-methyl micro emulsion.
For achieving the above object, the present invention is achieved in that
Microemulsion of the present invention mainly comprises following component:
A. weight concentration is 5%～20% haloxyfop-methyl;
B. weight concentration is 5%～40% emulsifier;
C. weight concentration is 0%～10% cosolvent;
D. weight concentration is 0%～10% antifreezing agent;
E. weight concentration is 10%～80% water.
Microemulsion of the present invention can prepare by following method:
Former medicine of haloxyfop-methyl and emulsifier are mixed in proportion, are stirred into the homogeneous oil phase, add the cosolvent mixing again after, add water while stirring, evenly get final product.
The used emulsifier of the present invention is alkyl benzene sulfonate calcium salt, styrene polyoxyethylene ether ammonium sulfate salt, benzylbiphenyl phenol polyethenoxy ether, phenethyl phenol polyethenoxy ether (n=15-30), phenethyl phenol polyethenoxy polyethenoxy ether, polyoxyethylene nonylphenol ether, alkylphenol polyoxyethylene formaldehyde condensation products, xenol APEO, farming breast 300
#, Nongru-700
#Etc. single agent or composite dose.Cosolvent is single agent such as methyl alcohol, ethanol, DMF, pyrrolidinyl ketone or composite dose.Antifreezing agent is single agent such as ethylene glycol, propane diols, glycerine, polyethylene glycol, sorbierite or composite dose.Water is natural water, running water, demineralized water or distilled water.
Also can add the stabilizing agent that weight concentration is 0%-5% in the microemulsion of the present invention, stabilizing agent is that weight concentration is PH buffer solution, 3-chloro-1,2 epoxy prapane, butyl glycidyl ether, phenyl glycidyl ether, cresyl glycidyl ether, polyethylene glycol diglycidyl ether, sorb sodium alkoxide etc. such as 0.1% aqueous citric acid solution, the benzoic acid aqueous solution, sodium bicarbonate aqueous solution, biphosphate sodium water solution.
Microemulsion of the present invention can be used for preventing and kill off rape, Soybean and Other Crops Tanaka's weeds: as annual gramineous weed and perennial grassy weeds such as barnyard grass grass, lady's-grass, eleusine indica, moleplant seed, annual bluegrass, amur foxtail, wild oat, net grass, caput grass.
Microemulsion of the present invention, production and processing, storing and use are all fool proof convenient, because its carrier is without organic solvent but water not only significantly reduces the pollution to environment, and reduced cost, also highly significant of herbicidal effect simultaneously.
