Abstract
The present invention relates to a chromafenozide micron emulsion and a preparation method thereof. The chromafenozide micron emulsion includes the components by weight: 1-15% of chromafenozide, 5-40% of a solvent, 5-25% of a cosolvent, 8-20% of an emulsifier, 1-5% of a stabilizer, and the balance water. The preparation method includes: dissolving the chromafenozide in the solvent, filtering, then adding a certain proportion of the emulsifier and the stabilizer in a preparation kettle, stirring fully to obtain the chromafenozide micron emulsion, and finally dividing and packaging into a finished product. The chromafenozide micron emulsion has good adhesiveness and permeability for crops and insects, is stable in product performance and high in insecticidal activity, improves the efficacy and reduces the dose of the insecticide.

3Chemical name: the 2'-tert-butyl group-5-methyl-2'-(3; the 5-dimethylbenzoyl) chroman-6-formylhydrazine; be mainly used on vegetables, tealeaves, fruit tree, rice field, other crop and the ornamental plant; not only to described plant safety; not having poisoning, and environment and ecology are not had harmful effect, is the desirable medicament in the comprehensive insect improvement system.
The modern formulations of pesticide promptly are the formulations of pesticide of matrix with water, promptly with big old formulations of missible oil of water baseization pesticidal preparations replace organic solvent consumption such as suspending agent, microemulsion, aqueous emulsions towards water baseization, ultramicronising, no efflorescence and the development of sustained release aspect.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 a kind of good liquid dosage form that replaces emulsifiable concentrates for agricultural chemicals.For the public nuisance-free agricultural chemicals of Development and Production green agricultural product, help the sustainable development of environmental protection and agricultural production, the inventor develops chitin synthesis inhibitor ring worm hydrazides, has invented 1-15% ring worm hydrazides microemulsion.
Summary of the invention
The object of the present invention is to provide a kind of ring worm hydrazides microemulsion, can reduce the environmental pollution of agricultural chemicals greatly, 1-15% ring worm hydrazides microemulsion adopts and contains a small amount of organic kind solvent and the good emulsifier of safety, and the feature of environmental protection is good, drug effect is high, stability is strong, easily processes and produces.
Technical scheme of the present invention: a kind of ring worm hydrazides microemulsion, each component is as follows by weight percentage: ring worm hydrazides 1-15%, solvent 5-40%, cosolvent 5-10%, emulsifier 8-20%, stabilizing agent 1-5%, surplus is a water.
Wherein, described 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.
Described emulsifier obtains by nonionic and anion surfactant are composite, contains 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, lauryl sodium sulfate, potassium chloride, the sodium sulphate in the composite emulsifier.
Described stabilizing agent is one or more mixing in antioxidant 264, epoxidized soybean oil, epoxy linseed oil, epoxy fat, pentaerythrite, xylitol, the pyrogallic acid.
Described stabilizing agent is one or more the mixing in peanut oil, antioxidant 264, epoxidized soybean oil, epoxy linseed oil, epoxy fat, pentaerythrite, xylitol, the pyrogallic acid.
Described water is running water or drinking water or natural water.
The preparation method of ring worm hydrazides microemulsion of the present invention: after ring former pruinescence solvent of worm hydrazides and cosolvent all dissolve, in the preparation still, add certain proportion emulsifier and stabilizing agent, obtain encircling worm hydrazides microemulsion after fully stirring, last packing, packing finished product.
The invention provides a kind of efficient, low toxicity, environmentally friendly, person poultry safety, the ring worm hydrazides microemulsion formulation that insect is difficult for developing immunity to drugs.Said preparation adopts the solvent of low toxicity and composite emulsifier to make 1-15% ring worm hydrazides microemulsion, the said preparation stable performance, and easily degraded, active high to crop pests, environmental pollution is very little.The 1-15% ring worm hydrazides microemulsion technological process of production is simple, and investment and cost of equipment are low, can carry out production strictly in line with rules and regulations.
Patent 1-15% ring worm hydrazides microemulsion of the present invention compared with prior art, provides a kind of more eco-friendly pesticidal preparations, satisfies the non-environmental pollution control needs of pest.Patent of the present invention has following advantage:
1,1-15% ring worm hydrazides microemulsion makes with the former powder of ring worm hydrazides, solvent and emulsifier.This invention preparation not only has crop and polypide and well adheres to and permeability, and properties of product are more stable, and insecticidal activity is higher, has improved drug effect, reduces the dosage of medicament simultaneously.
2,1-15% encircles worm hydrazides microemulsion high safety, the feature of environmental protection is good; the present invention substitutes most organic solvent with water; reduce environmental pollution, help ecological environmental protection, also can reduce production costs greatly; save a large amount of petrochemical industry resources; and the present invention adopts the solvent of low toxicity, significantly reduces organic solvent to the pollution of human body and environment and residual, produce in avoiding producing pollute, explosive and poisoning problem; pesticide processing is hanged down poison, ensure human and mammiferous safety and health.
3,1-15% ring worm hydrazides microemulsion can be used as the desirable public nuisance-free agricultural chemicals insecticide of integrated pest control fully.
