Description
Technical field
The invention belongs to pesticide field, relate to a kind of pesticide emulsion in water and preparation method thereof, relate in particular to aqueous emulsion of a kind of fluorine ring azoles and preparation method thereof.
Background technology
Fluorine ring azoles is a kind of novel systemic triazole bactericidal agent, not only has good protection, treats and root out activity, and inhales and preferable residual activity in having.Diseases such as the anthracnose on leaf spot, powdery mildew, rust and the grape on the crops such as banana, green onion garlic, celery, Kidney bean, melon, asparagus, peanut, beet, white rot there is good preventive effect.
At present, the fluorine ring azoles formulation of producing and using mostly is suspending agent and missible oil, also there is the epoxiconazole aqueous emulsion prescription open, but existing epoxiconazole aqueous emulsion still need use a certain amount of aromatic hydrocarbons organic solvent, and do not add suitable builder, its control efficiency is relatively poor, and fluorine ring azoles application concentration is big, control cost height.
Current, domestic pesticide liquid body preparation all needs to use not environmental protection organic solvents such as aromatic hydrocarbons basically, these organic solvents mainly contain benzene,toluene,xylene, methyl alcohol, dimethyl formamide, dimethyl sulfoxide (DMSO), acetone etc., the annual consumption of " triphen " is up to ten thousand tons of 20-30, but, it is low, inflammable and explosive and to shortcomings such as human and environment toxicity height that these solvents have a flash-point, organic solvent and auxiliary agent can all enter environment in the agricultural chemicals use, when causing serious environment pollution, also can damage health.1992, U.S. government put into effect the regulation of organic solvents such as forbidding toluene, dimethylbenzene in pesticidal preparations, and after this, European countries have also put into effect similar regulation in succession; By the end of in February, 2006,38 kinds of organic solvents that use in the Pesticidal products such as China Taiwan agricultural commission paraxylene, aniline, benzene, carbon tetrachloride, trichloro-ethylene management of having carried out limiting the quantity of, the content of dimethylbenzene, cyclohexanone can not surpass 10% in the agricultural chemicals finished product, dimethyl formamide and methyl alcohol should be less than 30%, and the content of ethylbenzene can not surpass 2%.Therefore need using environment-friendly type solvent to substitute not environmental protection such as aromatic hydrocarbons organic solvent commonly used, improve the friendly of pesticidal preparations environment.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of pesticide emulsion in water, and be intended to solve existing epoxiconazole aqueous emulsion and still need use not environmental protection organic solvents such as aromatic hydrocarbons, and control efficiency is poor, and the problem that fluorine ring azoles working concentration is big, cost is high.
Another purpose of the embodiment of the invention is to provide a kind of preparation method of pesticide emulsion in water.
The pesticide emulsion in water of the embodiment of the invention comprises the aqueous emulsion acceptable assistant of effective amount of actives fluorine ring azoles, effective dose and the organic solvent that can dissolve fluorine ring azoles of effective dose, comprises the builder salicylic acid and/or the turpentine oil of effective dose in the auxiliary agent.
The preparation method of the pesticide emulsion in water of the embodiment of the invention comprises the steps:
(1) with fluorine ring azoles, organic solvent, emulsifier adds in the reactor, mixes, and forms oil phase; Thickener and water are mixed, form water;
Wherein, aqueous phase evenly is mixed with salicylic acid; And/or
Evenly be mixed with turpentine oil in the oil phase;
(2) water is evenly mixed with oil phase, ultrasonic emulsification forms aqueous emulsion.
Compared with prior art, add builder salicylic acid and/or the turpentine oil that effective dose is arranged in the technique scheme.
Salicylic acid is a septichen, claims " antiphlogistic " of plant again, and microorganism is had antibiotic property, extensively is present in the higher plant.Salicylic acid is again a kind of phenols hormone, is also bringing into play important physiological action in plant corpus, can not only regulate some growth and development processes of plant, also the plant antibiont coerce with abiotic stress in bringing into play important effect.Plant is after being subjected to virus, bacterial invasion, the salicylic acid level that is infected the position can significantly increase, the protect from infection diffusion at position of downright bad scab occurs, the salicylic acid content of non-infection site also can raise in addition, thereby makes it infect the generation resistance again to pathogen.
Turpentine oil is that main component is terpenes (as an australene) by distillation or other method liquid that rosin extracted from the coniferale plant, and turpentine oil belongs to the high-flash flammable liquid, and penetration power is very strong.
In the pesticide emulsion in water of the embodiment of the invention, added the builder salicylic acid and/or the turpentine oil of effective dose, improved the control efficiency of epoxiconazole aqueous emulsion, reduced fluorine ring azoles working concentration and reduced cost.
