Abstract
The present invention relates to a kind of processing method of compound insecticide, the present invention is compound by the emulsification of cypermethrin and tetramethrin insecticide and adds the ingredients such as synergist, emulsifier, antifreezing agent and sustained release agent, obtain the uniform emulsified insecticide for being 1-5% containing cypermethrin and tetramethrin total amount, achieve the purpose that delay drug resistance, reduce toxicity and reduce single dose usage amount, to achieve the purpose that reduce insecticide cost.Insecticide enhancer component of the invention can inhibit in pest body the detoxication of itself, reduce the frequency of use of insecticide, reduce its drug resistance.Emphasis of the present invention solves the technical problem that insecticide efficacy time is short at this stage, has the characteristics that efficient, low toxicity, low dosage and wide spectrum.
Description
Technical field
The present invention relates to a kind of water and milk insecticides, belong to hygienic insecticide class.
Background technique
Due to the long-time service of public health insecticide, most of sanitary insect pest produces certain resist to insecticide
Pharmacological property, so that control efficiency reduces, the vicious circle for causing insecticide usage amount increasing.Existing insecticide is mainly with list
Based on agent, the effective content of single dose is less, is also easy to produce drug resistance；At the same time, most of insecticide easily decomposes in the soil, has
It is shorter to imitate action time.Therefore it is directed to two above problem, considers that a Compositional type insecticide with slow releasing function of exploitation is used
In prevention and treatment public health pest.By the scientific matching to two kinds of pesticides and reinforcing agent, it can not only improve and sanitary insect pest is prevented
The problem of controlling effect, and sanitary insect pest drug resistance can be slowed down.Simultaneously by screening sustained release agent, solves insecticide easily in soil
The problem of middle degradation.
Summary of the invention
It is an object of the invention to: a kind of composite insecticide for being able to suppress performance detoxication in pest body has been invented,
It solves resistance problems caused by single medicament, improve drug effect and improves its stability in the soil.Present invention choosing
The method for selecting cypermethrin and tetramethrin composite emulsifying prepares composite insecticide, while adding Octachlorodipropyl Ether and insecticide is inhibited to exist
The intracorporal detoxication of worm increases drug effect, reduces dosage.Above-mentioned purpose of the invention is achieved through the following technical solutions:
A kind of composite emulsifying insecticide containing cypermethrin is provided, by weight percentage: the desinsection of 0.1%-6% is living
Property ingredient, the reinforcing agent of 10-15%, 6-13% cosolvent, the sustained release agent of the emulsifier of 1-10%, 2-5%, 1-3% is antifreeze
The water of agent and surplus composition.
The insecticidal active ingredient is compounded by cypermethrin and tetramethrin with the weight ratio of ratio 2:15-25:3；
In the insecticide ingredient, the weight ratio of cypermethrin and tetramethrin is preferably 2:15-20:3.
The reinforcing agent is Octachlorodipropyl Ether.
The cosolvent is one or more mixing of tasteless kerosene, dimethylbenzene or trimethylbenzene.
The emulsifier is selected from shea butter ethyoxyl amine salt, styryl phenyl polyoxyethylene ether, alkylphenol formaldehyde tree
Rouge polyoxyethylene ether, styrene phenol formaldehyde resin polyoxyethylene ether, polyoxyethylene polyoxypropylene block co-polyether, secondary octyl phenol
Polyoxyethylene ether, castor oil polyoxyethylene ether, one or more mixing in fat alcohol alkoxy compound TWEEN Series.
The sustained release agent is 2,4-DTBP, 2,6- di-tert-butyl-4-methy phenol, glycidol ether, season penta
One of tetrol and beta-cyclodextrin or a variety of mixing.
The antifreezing agent is ethylene glycol, sodium chloride, K2CO3And one of urea or a variety of mixing.
A kind of preferred compound insecticidal aqueous emulsion of the present invention, comprises the following components in percentage by weight:
The cypermethrin of 0.05-2%, the tetramethrin of 0.03-4%, the reinforcing agent of 10-15%, 6-13% cosolvent, 1-
10% emulsifier, the sustained release agent of 2-5%, the antifreezing agent of 1-3% and surplus water composition.
Preparation method are as follows:
A. cypermethrin, tetramethrin and reinforcing agent are dissolved in the cosolvent of 30-50ml, the emulsification of total amount 30% is added
Agent and sustained release agent obtain oily phase in 25-30 DEG C of emulsification；
B. resulting water phase mixing is mutually mixed with purified water, antifreezing agent by oily, adjust pH and make 4≤pH≤7, in 25-30
DEG C emulsification uniformly, obtain the compounded pesticides containing cypermethrin and tetramethrin.
The adjusting pH value is by one of acetic acid, hydrochloric acid, benzoic acid, ethylenediamine and triethylamine or a variety of mixing
Use realization.
In the compounding water and milk method for producing insecticide, water phase and oil are mutually mixed to get thick lotion under mechanical stirring,
Then the compound insecticidal aqueous emulsion obtained thick lotion homogeneous with high pressure homogenizer.
The present invention also provides application of the compound insecticidal aqueous emulsion in prevention and treatment sanitary insect pest.
The sanitary insect pest is mainly for mosquitos and flies.
Tetramethrin for sanitary insect pest mosquito, fly is with super strength knocks down activity, because it is with high-vapor-pressure, especially suitable for
The sprinkling of external environment space, but it is not high for the killing activity of mosquito, fly.
The lethal effect of cypermethrin is 3 times of Permethrin or so, the present invention by by cypermethrin and tetramethrin compounding,
When preventing and treating sanitary insect pest, not only there is preferable down effect, but also killing activity is also higher.
The beneficial effects of the present invention are:
Simple production process of the present invention, use is safe, compared to the use that missible oil reduces organic solvent, reduces to ring
The pollution in border has fabulous knocking down property and lethal effect to more environment-friendly.Have in external environment prevention and treatment sanitary insect pest aobvious
The synergistic effect of work can obviously reduce pharmacy application amount, delay the generation of sanitary insect pest drug resistance, while enhance it in soil
In stability, have certain slow release long-acting effect.
