Abstract
The imidacloprid micro emulsion is prepared with imidacloprid, cosolvent, emulsifier and water. It raises the storage stability of imidacloprid, increases its adhesion and permeability to plants and reduce used of organic solvent to reduce environmental pollution and raise safety for application.
Description
The present invention relates to a kind of formulation and production method thereof of agricultural chemicals, relate in particular to imidacloprid emulsion and production method thereof.
Imidacloprid is a kind of novel Nitromethylene insecticides of being developed jointly by Japan special agricultural chemicals Co., Ltd and Bayer A.G, characteristics with efficient, low toxicity, interior absorption wide spectrum, to pierce-suck type, scratching mouthparts insect, special efficacy is all arranged as aphid, leafhopper, plant hopper, thrips, aleyrodid and other resistant strain; In addition, Lepidoptera, diptera and coleoptera also there is certain preventive effect.Simultaneously, have stomach toxicity and action of contace poison, mechanism of action mainly is optionally to suppress insect nervous system nicotinic acid acetylcholinesterase acceptor, and the normal conduction of blocking-up insect central nervous system causes insect paralysis to occur and death.
At present, be liquid formulation comparatively easily in the use of pesticidal preparations, use for a long time at most, the widest be emulsion (missible oil).In the process of processing emulsion, need a large amount of organic solvents, as benzene,toluene,xylene or the like.The use of a large amount of organic solvents not only causes the waste of industrial chemicals, simultaneously, has brought very big threat for environment and human health, is unfavorable for China's environment sustainable development implementation.In recent years, proposed to forbid the part organic solvent in minority developed countries such as the U.S..Therefore, exploitation reduces or gets rid of the new liquid formulation of these organic solvents, has become a kind of imperative trend, and wherein Water-borne modification is exactly one of dominant direction of formulations of pesticide development.And new pesticide processing method also can increase new feature to agricultural chemicals, more can give full play to the action characteristic of former medicine self, overcome and remedy or cover the deficiency of the intrinsic formulation of former medicine, improve physico chemistry and biological property, enlarge range of application, prolong the service life of medicament.
Microemulsion is a kind of new liquid formulation of developing in recent years, belongs to a kind of of aqueous emulsion, and it is medium with water, act on water-fast effective active component by dispersion, emulsification etc., by homogenize technology, it is dispersed in the water, form the thermodynamic stable system of oil-in-water type.Disperse phase is liquid-drop diameter≤0.1 μ m after homogenize, so appearance transparent, physics, chemical stability are good, and is strong to plant and insect tissue cell permeability, the absorption ratio height, preventive effect is good, simultaneously, have production, storing and safe in utilization, environmental pollution is little, helps the improvement of ecotope.The main formulation of the Imidacloprid of domestic production is wetting powder and missible oil, still finds no the report that closes imidacloprid emulsion.
The object of the invention is to provide a kind of imidacloprid emulsion and production method thereof, reduces the use of organic solvent, thereby reduces environmental pollution, and the physics and the chemical stability that improve medicament, prolongs the service life of medicament.
Below narrate main contents of the present invention:
Imidacloprid emulsion is made up of Imidacloprid, cosolvent, emulsifier and water, and wherein the percentage by weight of various components is:
Imidacloprid 1～50%
Cosolvent 5～30%
Emulsifier 5～30%
Water 10～80%
Cosolvent described in the above-mentioned imidacloprid emulsion is phenmethylol, dimethyl formamide, ethanol, isopropyl alcohol, n-butanol, n-amyl alcohol, acetone, cyclohexanone and the combination that well known to a person skilled in the art any one or two kinds to three kinds in the cosolvent.
Emulsifier described in the above-mentioned imidacloprid emulsion is a farming breast 500
#, farming breast 1600
#, 2201,700
#, Tween-80, Tx-10,0201, AE0-9 and well known to a person skilled in the art emulsifier any two or three the combination.
Above-mentioned imidacloprid emulsion is characterized in that containing synergist, and purpose is in order to improve control efficiency, and wherein the percentage by weight of various components is:
Imidacloprid 1～50%
Cosolvent 5～30%
Emulsifier 5～30%
Synergist 5～10%
Water 20～80%
The described synergist of above-mentioned imidacloprid emulsion is piperonyl butoxide, Octachlorodipropyl Ether, azone and well known to a person skilled in the art any one of synergist.
Above-mentioned imidacloprid emulsion is characterized in that containing stabilizing agent, and purpose is physics and the chemical stability that increases microemulsion, and wherein the percentage by weight of various components is:
Imidacloprid 1～50%
Cosolvent 5～30%
Emulsifier 5～30%
Synergist 5～10%
Stabilizing agent 5～10%
