Abstract

The invention discloses an emamectin-benzoate and methomyl microemulsion and a preparation method thereof. The microemulsion mainly comprises 5-30 percent of methomyl, 0.5-2 percent of emamectin-benzoate, 0.5-2 percent of penetrating agent, 0.5-5 percent of synergistic agent, 1-5 percent of antifreeze, 5-25 percent of latent solvent, 5-25 percent of emulsifier and the balance water for complement. The microemulsion is a pesticide with high efficiency, low toxicity and strong systemic capability, has very good prevention effect on diamond back moths on Cruciferae and additionally has special effect on other pests and insects with sucking mouth parts and scratching mouth parts.

Description

A kind of first dimension salt Methomyl microemulsion and preparation method thereof
Technical field
The present invention relates to a kind of pesticidal preparations, relate in particular to a kind of first dimension salt Methomyl microemulsion and preparation method thereof.
Background technology
Emamectin-benzoate (being called for short first dimension salt) is a kind of super-high-efficient, environmental type insecticide, miticide, has wide spectrum, noresidue, the high characteristic of selecting.Be the product of Avermectin through chemosynthesis, compare with Avermectin that activity has improved 100～200 times, toxicity reduces the 2-3 order of magnitude, and former medicine is medium poison, and its formulation products is a low toxicity.It is biogenic class public nuisance-free agricultural chemicals.
The mechanism of action makes paralysis, food refusal, slow or motionless rapidly in the insect several hours by suppressing the intranueral aminobutyric acid transmission of pest movements, and dead in 24-28 hour.
The mode of action is main action of contace poison with stomach toxicity, crop there is not interior absorption energy, use crop epidermal tissue but can effectively infiltrate, thereby have the longer longevity of residure, to control cotton bollworm, diamond-back moth, Lepidoptera, mite class, coleoptera and homoptera pest have high activity, and do not produce and intersect with other crops, soil and in the noresidue of easily degrading, free from environmental pollution, in the routine dose scope to useful insect and natural enemy, people, animal safety, can with most of combined use of pesticides.
Methomyl (methom), high malicious broad spectrum activity carbamic acid acid pesticide.Acetylcholinesteraseinhibitors inhibitors, have tag, stomach poison function.Its insecticidal spectrum is wide, and effect is applicable to the insect on the various crop such as control fruit tree, vegetables, cotton, tobacco, lawn, as aphid, thrips, mythimna separata, codling moth, cotton bollworm, the snout moth's larva of rice, plant hopper etc. rapidly.Methomyl is degraded easily in environment, and is environmentally safe.
At present, be liquid formulation comparatively easily in the use of pesticidal preparations, use for a long time at most, the widest be missible oil.In the process of processing missible oil, need a large amount of organic solvents, as benzene,toluene,xylene etc.A large amount of uses of organic solvent not only cause the waste of industrial chemicals, simultaneously, return environment and human health and have brought very big threat.Therefore, exploitation reduces or reforms the new liquid formulation of these organic solvents, has become a kind of imperative trend, and wherein Water-borne modification is exactly one of dominant direction of formulations of pesticide development.And new pesticide processing method also can increase new feature to agricultural chemicals, more can give full play to the action characteristic of former medicine self, overcome and remedy or cover the deficiency of the intrinsic formulation of former medicine, improve physico chemistry and biological property, enlarge range of application, prolong the service life of medicament.
Microemulsion is a kind of new liquid formulation of developing this year, belongs to a kind of of aqueous emulsion, and it is medium with water, act on water-fast effective active component by dispersion, emulsification etc., by homogenize technology, it is dispersed in the water, form the thermodynamic stable system of oil-in-water type.Disperse phase is liquid-drop diameter≤0.1um after homogenize, so appearance transparent, physics, chemical stability are good, and is strong to plant and insect tissue cell permeability, the absorption ratio height, and preventive effect is good.Simultaneously, have production, storing and safe in utilization, environmental pollution is little, helps the improvement of ecotope.
Summary of the invention
The purpose of this invention is to provide a kind of first dimension salt Methomyl microemulsion and preparation method thereof.
Another object of the present invention provides a kind ofly has the better prevention effect to diamond-back moth, reduces the consumption of organic solvent, the first dimension salt of corresponding minimizing environmental pollution and the microemulsion of Methomyl Recompounded pesticide.
First dimension salt Methomyl microemulsion, its each constituent and percentage by weight thereof are: first dimension salt 0.5-2%, Methomyl 5-30%, synergist 0.5-5%, antifreezing agent 1-5%, bleeding agent 0.5-2%, cosolvent 5-25% and emulsifier 5-25%, water surplus supplies 100%.
Described cosolvent can be one or more in cyclohexanone, methyl alcohol, ethanol, dimethylbenzene, N-Methyl pyrrolidone, dimethyl formamide, the cyclohexane.
Described emulsifier is one or more among commercially available Nongru-700 #, agricultural newborn 400#, agricultural newborn 500#, farming breast 1601, farming breast 1602, farming breast 601, farming breast 602, farming breast 603, TX-10,0201,2201, the BY-140.
Described bleeding agent is one or more in sldium lauryl sulfate, sodium alkyl sulfonate, alkylbenzenesulfonate, lauryl alcohol sodium sulphate, Negel, sodium lignin sulfonate, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, the azone.
Described synergist be in piperonyl butoxide, azone, the Octachlorodipropyl Ether one or more.
Described antifreezing agent is one or more in ethylene glycol, polyethylene glycol, urea and the glycerine.
The production method of microemulsion of the present invention, comprise and first is tieed up salt and Methomyl is dissolved in the cosolvent, drop into emulsifier then, synergist and stabilizing agent, stir, put into then and mix strongly in the homogenizer that dispersion medium water is housed and homogenize, obtaining outward appearance at last is limpid transparent first dimension salt Methomyl microemulsion.
The advantage that the present invention has:
1. the present invention has very strong synergy preventive and therapeutic effect to diamond-back moth, has enlarged the control spectrum in addition, can prevent and treat other insects on vegetables, fruit tree, the cotton.
2. storage-stable of the present invention is good;
3. the present invention is strong to adhesiveness and the permeability of plant;
4. the present invention has reduced consumption of organic solvent, and environmental pollution is few, and is safe in utilization;
