Abstract
The invention provides a chlorpyrifos microemulsion containing chenopodium ambrosioides oil and a preparation method thereof. The chlorpyrifos microemulsion takes the chlorpyrifos as a main raw material and is added with the chenopodium ambrosioides oil. The preparation method is as follows: firstly the chlorpyrifos is mixed with the chenopodium ambrosioides oil based on proportion, secondly latent solvent, surfactants, defoamers and water are added to the mixture according to the mixture ratio and are mixed evenly, finally anti-freezers are added to the mixture and stirred evenly to form the transparent, stable, isotropical and one-phase microemulsion. The microemulsion of the invention is efficient and low-toxic and has little pollution to environment. The preparation method is simple and has obvious economic benefit and significance in environmental protection.
Description
Technical field
The invention belongs to technical field of pesticide preparations, more specifically relate to a kind of chlorpyrifos micro emulsion and compound method thereof that contains the chenopodium ambrosiodies essential oil.
Background technology
Chlopyrifos (Chlorpyrifos) is the efficient organophosphorus insecticide that substitutes acephatemet and the contour malicious agricultural chemicals of parathion, surpass 88 countries in the whole world and obtained registration, insect had tag, stomach toxicity and fumigation action, can be used on numerous field crops such as water paddy and wheat class, corn, soybean, peanut, cotton, fruit tree, tea tree, sugarcane, vegetables and flowers and the economic crops, over one hundred kind of insects such as the control snout moth's larva of rice, rice leaf roller, wheat mythimna separata, leafhopper, cotton bollworm, aphid and two spotted spider mite also have the better prevention effect to underground insect, animal parasite.In recent years, along with the pest resistance to insecticide level improves, the excessive use phenomenon of chlopyrifos is comparatively serious.Ecotoxicology discovers that chlopyrifos has potential danger to ecotope, and is higher to aquatile toxicity, and human lives's influence is also caused people's attention.There is strict regulation in many countries to the residual quantity of chlopyrifos in agricultural product.Therefore, the high-efficiency environment friendly novel form becomes the research focus.The whole nation has 15% left and right sides agricultural chemicals producer to have the chlopyrifos Related product approximately now, mainly contains formulations such as missible oil, granule, microemulsion.
(Micro-emulsion ME) is thermodynamic stable system by water, oil, surfactant and the cosurfactant spontaneous transparent or semitransparent homogeneous phase that forms under proper proportion to microemulsion, is oil-in-water (O/W) type micro emulsion.Fields such as emulsion polymerisation, agricultural chemicals, medicine, food, daily-use chemical industry, organic chemistry now have been widely used in.Microemulsion is the external a kind of pesticides new formulation that the occurs eighties in 20th century, with water is main solvent, a large amount of organic solvents have been saved, it is a kind of environment amenable environment friendly agricultural preparation, can select as the novel form that replaces missible oil, and be applicable to the pesticide original medicine kind that some has only the wetting powder formulation.
The natural products that is richly stored with in the plant, the Secondary Metabolism of Plant product is the little molecule of naturally occurring important biomolecule, is separated to thousands of plant species chemical compositions from the high and rudimentary plant that is distributed in different monoids all over the world so far.The application of plant resource auxiliary agent and relevant agricultural chemicals helps reducing access times and consumption, the generation of alleviation pest resistance, minimizing environmental pollution and the residue of pesticide of harmful insecticides adjuvant and chemical pesticide.Chenopodium ambrosiodies is that Li Keli belongs to, and annual or perennial herb now is distributed widely in the torrid zone, the world, subtropics and area, temperate zone.China mainly is distributed in provinces and cities such as Fujian, Guangdong, Hainan, Guangxi, is born in other wilderness, village, roadside, riverbank and small stream limit etc. more and locates, and becomes the important injurious weed in rural area in many places.
Summary of the invention
The purpose of this invention is to provide a kind of chlorpyrifos micro emulsion and compound method thereof that contains the chenopodium ambrosiodies essential oil, this microemulsion is efficient, low toxicity, and environmental pollution is small, and the preparation method is easy, has remarkable economic efficiency and environmental protection meaning.
The chlorpyrifos micro emulsion that contains the chenopodium ambrosiodies essential oil of the present invention: with the former medicine of chlopyrifos is primary raw material, and adds the chenopodium ambrosiodies essential oil.
The compound method that contains the chlorpyrifos micro emulsion of chenopodium ambrosiodies essential oil of the present invention: earlier the former medicine of chlopyrifos is mixed in proportion with the chenopodium ambrosiodies essential oil, add cosolvent, surfactant, defoamer, water according to described proportioning then, mix; Add antifreeze at last, stirring forms the microemulsion of transparent, stable, an isotropic phase.
Remarkable advantage of the present invention is: the present invention adds an amount of chenopodium ambrosiodies essential oil in chlopyrifos, make the chenopodium ambrosiodies essential oil play good synergistic effect to chlopyrifos, and the consumption of minimizing chlopyrifos, when improving the chlopyrifos result of use, make this product reach the effect of low toxicity, meet the requirement of Environmental security; The present invention adopts the proper raw material batching, make the thermodynamic stable system of the transparent or semitransparent homogeneous phase of the spontaneous formation of solution, be oil-in-water (O/W) type micro emulsion, make active ingredient chlopyrifos and the fully combination of chenopodium ambrosiodies essential oil, and be evenly distributed, stable, an isotropic phase, the term of validity is long, effect is remarkable, has characteristics such as production, use, storing safety; The preparation method is easy, has remarkable economic efficiency and environmental protection meaning.
