Abstract
The invention discloses a hexaflumuron microemulsion and a preparation method thereof. The hexaflumuron microemulsion comprises the following components in percentage by weight: 1-10% of hexaflumuron, 5-60% of a solvent and a cosolvent, 5-20% of an emulsifier, 1-5% of a stabilizer and the balance of deionized water. The preparation method comprises the following steps: fully dissolving bulk hexaflumuron with the solvent and the cosolvent; adding the dissolved bulk hexaflumuron to a blending kettle; and then adding the emulsifier, the stabilizer and the deionized water in a certain proportion, and fully and evenly mixing to obtain the hexaflumuron microemulsion. The hexaflumuron microemulsion is efficient, low-toxic, environmentally-friendly and safe for people and livestock.
Description
Technical field
The present invention relates to a kind of agricultural insecticide and preparation method thereof, a kind of specifically fluorine bell urea microemulsion and preparation method thereof.
Background technology
Fluorine bell urea belongs to the benzoyl urea insecticide, is chitin synthesis inhibitor, has very high desinsection and ovicidal activity, and quick-acting, especially prevents and treats cotton bollworm, can be used for cotton, potato and fruit tree and prevents and treats multiple coleoptera, diptera, Homoptera insect.Have and studies show that much this insecticide can also suppress insect food speed, so the power of knocking down is faster arranged when killing off the insect pests by suppressing to cast off a skin.The insecticidal activity height of fluorine bell urea, insect is difficult for developing immunity to drugs, and uses the back noresidue, to crop safety, crop products is had no adverse effects.Therefore, fluorine bell urea microemulsion can be used as the desirable environmental-pollution insecticide of integrated pest control.
The formulations of pesticide such as missible oil, pulvis have been brought into play important function in China's pesticide industry development course, in Pesticidal products, also occupy very big ratio, yet these fall behind formulation and have fatal defectives such as environmental pollution is big, manufacturing cost height, can not satisfy the demand of agricultural sustainable development.
The modern formulations of pesticide promptly are the formulations of pesticide of matrix with water to water baseization, ultramicronising, no efflorescence and the development of sustained release aspect, replace backward formulations such as missible oil as water baseization pesticidal preparations such as suspending agent, microemulsion, aqueous emulsions.Wherein microemulsion be a kind of organic solvent can be less with in addition the novel pesticide formulation of no, good drug efficacy, environmentally-friendly water-basedization, also be the good liquid dosage form that a kind of alternative missible oil etc. falls behind formulation.Public nuisance-free agricultural chemicals formulation for the Development and Production green agricultural product helps the sustainable development of environmental protection and agricultural production, and the inventor develops the water base chemical preparation of fluorine bell urea, and then has finished the present invention.
Summary of the invention
The present invention is directed to the environmental pollution that exists in the prior art, harm is healthy and shortcomings such as manufacturing cost height, a kind of efficient, low toxicity, environmentally friendly, person poultry safety be provided and easily produce and the fluorine bell urea microemulsion that uses and preparation method thereof.
Technical scheme: for achieving the above object, the invention provides a kind of fluorine bell urea microemulsion, each component is as follows by weight percentage: fluorine bell urea 1-10%; Solvent and cosolvent 5-60%; Emulsifier 5-20%; Stabilizing agent 1-5%; Surplus is a deionized water.
Wherein: solvent and cosolvent are one or more the mixing in dimethylbenzene, acetone, cyclohexanone, ethyl acetate, dimethyl formamide, N-Methyl pyrrolidone, dimethyl sulfoxide (DMSO), diethyl phthalate, the dibutyl phthalate.
Emulsifier is one or more the mixing in alkylphenol polyoxyethylene, styryl phenol polyethenoxy ether, alkaryl phenol polyethenoxy ether phosphate, castor oil polyoxyethylene ether, alkylbenzenesulfonate, alkylphenol-polyethenoxy phosphate, maleic acid di-sec-octyl sodium sulfonate, polyol fatty acid ester and ethylene oxide adduct thereof, castor oil, potassium chloride, the sodium sulphate.
Stabilizing agent is one or more the mixing in antioxidant 264, epoxidized soybean oil, epoxy linseed oil, epoxy fat, pentaerythrite, xylitol, the pyrogallic acid.
Fluorine bell urea microemulsion preparation method is: after with solvent and cosolvent the former medicine of fluorine bell urea all being dissolved, be added in the compounding kettle, add certain proportion emulsifier, stabilizing agent and deionized water again and fully mix, obtain fluorine bell urea microemulsion after stirring.
Fluorine bell urea microemulsion provided by the invention has the following advantages.
1, efficient, the low toxicity of fluorine bell urea microemulsion provided by the invention, environmentally friendly, person poultry safety, the fluorine bell urea microemulsion formulation that is difficult for developing immunity to drugs.Adopt the solvent and the emulsifier of low toxicity, stable performance, easily degraded, active high to corps diseases, environmental pollution is very little.The technological process of production is simple, and the investment of production equipment expense is low, is easy to processing.
2, fluorine bell urea microemulsion provided by the invention substitutes most organic solvent with deionized water; reduce environmental pollution; help ecological environmental protection; also can reduce production costs greatly, save a large amount of petrochemical industry resources, and adopt the solvent of low toxicity; significantly reduce organic solvent to the pollution of human body and environment and residual; produce pollution, explosive and poisoning problem in avoiding producing, make pesticide processing produce low poisoning, ensure people and animals' safety and health.
3, fluorine bell urea microemulsion provided by the invention not only has crop and well adheres to and permeability, and properties of product are stable, and activity is higher, has improved drug effect, reduces the dosage of medicament simultaneously.
4, fluorine bell urea microemulsion provided by the invention can be used as the desirable public nuisance-free agricultural chemicals bactericide of integrated pest control fully.
