Abstract
The invention relates to methylamino abamectin benzoate micro-emulsion serving as an agricultural insecticide and a preparation method. The methylamino abamectin benzoate micro-emulsion is characterized by comprising the following components in percentage by weight: 0.5 to 10 percent of methylamino abamectin benzoate, 5 to 20 percent of solvent, 1 to 15 percent of cosolvent, 5 to 40 percent of emulsifier, 0.1 to 3 percent of stabilizing agent and the balance of water. The preparation method comprises the following steps of: stirring the solvent, the cosolvent and the methylamino abamectin benzoate according to proportion at the speed of between 40 and 100 r/min to uniformly mix the components; adding the emulsifier and the stabilizing agent according to proportion; uniformly stirring the components; adding the water based on the total mass of 100 percent; and continuing stirring for 1 to 2 hours to obtain a uniform and transparent solution product. The methylamino abamectin benzoate micro-emulsion has the advantages of reducing environmental pollution, replacing a part of solvent by using water, reducing the using amount of an aromatic organic solvent, improving insecticidal effect and improving prevention and control effects and the effective utilization ratio of a medicament, along with high permeability and spreading uniformity to insects and plants.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of agricultural insecticide emamectin benzoate microemulsion and preparation method.
Background technology
Emamection benaoate is an agricultural insecticide, and the insecticidal activity that compares the lepidoptera pest larva with the parent Avermectin is significantly improved, and toxicity but reduces greatly.Active in the parent Avermectin, be better than conventional dose simultaneously.Its function is the effect that strengthens neurotransmitter such as glutamate and aminobutyric acid, thereby makes a large amount of chlorions enter nerve cell, makes the cell function forfeiture, upsets nerve conduction.Stop feed very soon, neural paralysis after making larva contact medicament.Medicament can be penetrated into the epidermis of target crop, and long-term drug effect is arranged.Main in the market preparation is a missible oil, mainly adopts aromatic organic solvent, and as benzene,toluene,xylene etc., environmental pollution is heavier, needs to consume a large amount of organic solvents such as dimethylbenzene, has both caused environmental pollution easily, wastes resource again, increases cost.
Summary of the invention
The purpose of this invention is to provide a kind of environmental protection formulation, substitute aromatic organic solvent with water, improve the fineness of emamection benaoate in emulsion, and improve a kind of agricultural insecticide emamection benaoate microemulsion and the preparation method of the effective rate of utilization of emamection benaoate.Realize that the technical scheme of taking of the present invention is: this emamection benaoate microemulsion, by weight percentage, contain emamection benaoate 0.5-10%, solvent 5-20%, cosolvent 1-15%, emulsifier 5-40%, stabilizing agent 0.1-3%, water is supplemented to 100%.
Solvent is an aromatic hydrocarbon solvent, as benzene,toluene,xylene, ethylbenzene, acetone, adopts wherein a kind of.
Solvent is that esters solvent is methyl formate, Ethyl formate, propyl formate, butyl formate, methyl acetate, ethyl acetate, propyl acetate, butyl acetate, methyl propionate, ethyl propionate, butyl propionate, methyl butyrate, ethyl butyrate, butyl butyrate.
Cosolvent is an alcohols;
Co-solvent is methyl alcohol, ethanol, propyl alcohol, isopropyl alcohol, butanols, isobutanol, ethylene glycol, propane diols; Adopt one or more composition.
Emulsifier is anion surfactant or non-ionic surface active agent, anion surfactant is that calcium dodecyl benzene sulfonate, non-ionic surface active agent are alkylphenol polyoxyethylene, benzylphenol APEO, styryl phenol polyethenoxy ether, triphenyl vinyl phenol APEO polyethenoxy ether, fatty alcohol-polyoxyethylene ether, adopts wherein a kind of.
Stabilizing agent is urea, polyvinyl alcohol, polyacrylamide, adopts wherein a kind of.
The method for preparing the emamection benaoate microemulsion is: at first in proportion solvent, cosolvent and emamection benaoate are stirred miscible even under 40-100 rev/min rotating speed, drop into emulsifier and stabilizing agent then in proportion, stir again, add water at last and add to 100%, continue to stir 1-2 hour, become the homogeneous transparent solution product.
The present invention has reduced environmental pollution, and water has substituted partial solvent, has reduced the usage amount of aromatic organic solvent; Improved drug effect, emamection benaoate is to the penetrating ability of insect and plant and sprawl uniformity, has improved the effective rate of utilization of control efficiency and medicament.
