Abstract
The invention relates to a quizalofop-p-ethyl emulsion in water comprising the following components by the weight percentage: 20% of quizalofop-p-ethyl, 45% of a solvent and a cosolvent, 15% of an emulsifier, 2% of a dispersant, 5% of a stabilizer, 5% of an antifreezer, and 8% of deionized water. Quizalofop-p-ethyl is dissolved in the solvent and the cosolvent, then the emulsifier, the stabilizer and the dispersant are added, and thus an oil phase is prepared; the antifreezer is mixed with deionized water to obtain a water phase, under a high shear condition, the oil phase is slowly added into the water phase or the water phase is slowly added into the oil phase, and thus the quizalofop-p-ethyl emulsion in water is prepared. The quizalofop-p-ethyl emulsion in water has the characteristics of being high in efficiency, low in toxicity, friendly to the environment, safe to human and animals, and easy to degrade.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, specifically a kind of quizalofop-p-ethyl emulsion in water.
Background technology
Quizalotop-ethyl has another name called smart quizalofopethyl, is to have removed the improvement goods after inactive optical isomer in the process of synthetic quizalofopethyl, is a kind of aryl phenoxy propionic acid class selectivity, inner sucting conduction type, cauline leaf processing low toxicity herbicide.Its mechanism of action and herbicide spectrum is similar to quizalofopethyl, by weeds cauline leaf, absorbs, and Bidirectional Conduction up and down in plant corpus, is accumulated in top and mitogenetic between two parties, suppresses cell fatty acid synthetic, makes weeds necrosis.Quizalotop-ethyl is a kind of novel dry land cauline leaf inorganic agent of high selectivity, has the selectivity of height between grassy weed and dicotyledonous crops, and the grassy weed in broad leaf crop field is had to good preventive effect.Annual weed is subject to after medicine, and young leaves flavescence in 2-3 days, stops growing, and within 4-7 days, cauline leaf is downright bad shape, and in 10 days, whole strain is withered.Perennial weed is subject to after medicine, and medicament to the conduction of underground rhizome tissue, makes it to lose regeneration capacity rapidly.Speed of action is faster, and efficacy stability is not subject to the impact of the environmental conditions such as rainwater temperature and humidity.
Quizalotop-ethyl mainly be take missible oil as main at present, because cream preparation mainly adopts aromatic organic solvent, prepares, and a large amount of aromatic organic solvents, as toluene, dimethylbenzene, mixed toluene etc. not only have certain pollution to environment, also consumes a large amount of petrochemical industry resources.Preparation Forms of Modern Pesticide is towards water baseization, ultramicronising, without efflorescence with control the development of release aspect, the formulations of pesticide that the water of take is matrix, wherein aqueous emulsion is a kind of organic solvent few novel pesticide formulation by even no, good drug efficacy, environmentally-friendly water-basedization as far as possible, is also a kind of good liquid dosage form that replaces emulsifiable concentrates for agricultural chemicals.。
Summary of the invention
The object of the invention is to overcome the environmental pollution that exists in prior art, endanger the defects such as healthy and manufacturing cost is high and a kind of efficient, the low toxicity developed, environmentally friendly, person poultry safety and the quizalofop-p-ethyl emulsion in water easily producing and use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of quizalofop-p-ethyl emulsion in water, and each component is as follows by weight percentage: Quizalotop-ethyl 20%, solvent and cosolvent 45%, emulsifier 15%, dispersant 2%, stabilizing agent 5%, antifreezing agent 5%, deionized water 8%.
Wherein: solvent and cosolvent are one or more the mixing of dimethylbenzene, toluene, isobutanol, ethyl acetate, NOP, repefral, diethyl phthalate, dibutyl phthalate, aromatic hydrocarbon solvent Solvesso100, aromatic hydrocarbon solvent Solvesso150, aromatic hydrocarbon solvent Solvesso200.
Emulsifier is one or more the mixing in alkylphenol polyoxyethylene, alkaryl phenol polyethenoxy ether phosphate, castor oil polyoxyethylene ether, alkylbenzenesulfonate, alkylphenol-polyethenoxy phosphate, polyoxyethylene sorbitan fatty acid ketone, sorbitan ester, fatty alcohol-polyoxyethylene ether, disecoctylmaleate sodium sulfonate, castor oil, lauryl sodium sulfate.
Dispersant is alkyl phenol formaldehyde resin polyoxyethylene ether sulphate.
Stabilizing agent is one or more the mixing in peanut oil, antioxidant 264, epoxidized soybean oil, epoxy linseed oil, epoxy fat, pentaerythrite, xylitol, pyrogallic acid.
Antifreezing agent is one or more the mixing in ethylene glycol, propane diols, glycerine, diethylene glycol.
Quizalofop-p-ethyl emulsion in water preparation method provided by the invention is: Quizalotop-ethyl is dissolved in solvent and cosolvent, then adds emulsifier, stabilizing agent and dispersant, make oil phase; Antifreezing agent and deionized water are mixed to get to water, under shear conditions, oil phase is slowly joined to water in or water is slowly joined in oil phase, make quizalofop-p-ethyl emulsion in water.
Quizalofop-p-ethyl emulsion in water provided by the invention has advantages of following:
1, compared with prior art, quizalofop-p-ethyl emulsion in water provided by the invention is as a kind of water base chemical preparation, has efficient, low toxicity, environmentally friendly, person poultry safety, and the feature such as be difficult for developing immunity to drugs.Adopt solvent and the emulsifier of low toxicity, stable performance, easily degraded, high to corps diseases activity, environmental pollution is very little.The technological process of production is simple, and investment of production equipment expense is low, is easy to processing.
2, quizalofop-p-ethyl emulsion in water provided by the invention substitutes most organic solvent with deionized water; reduce environmental pollution; be conducive to ecological environmental protection; also can greatly reduce production costs, save a large amount of petrochemical industry resources, and adopt the solvent of low toxicity; greatly reduce organic solvent to the pollution of human body and environment and residual; in avoiding producing, produce pollution, explosive and poisoning problem, make pesticide processing produce low poisoning, ensure people and animals' safety and health.
3, quizalofop-p-ethyl emulsion in water provided by the invention not only has and well adheres to and permeability crop, and properties of product are stable, and activity is higher, has improved drug effect, reduces the dosage of medicament simultaneously.
