Abstract
The invention provides a microemulsion pesticide. The microemulsion pesticide is obtained by compounding propiconazole and avermectin. The microemulsion pesticide preferably comprises the following components in percentage by weight: 1.0-10% of propiconazole, 0.5-6% of abamectin, 5-30% of solvent, 1-30% of emulsifier, 0-5.0% of anti-freezing agent, 0-2.0% of defoaming agent and the balance of water. According to the invention, through mixing the propiconazole and the abamectin, an effect of preventing rice sheath blight can be achieved more obviously when control effects on insects and pest mites are obtained; in addition, according to the invention, as the propiconazole and the abamectin are mixed to form a microemulsion, the usage amount of an organic solvent is also reduced and environment-friendly requirements of human are satisfied. The invention further correspondingly provides a preparation method of the microemulsion pesticide.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of micro-emulsion insecticide and preparation method thereof, this agricultural chemicals is used for preventing and treating rice sheath blight disease.
Background technology
Paddy rice is one of Three major grain crops of China, but rice sheath blight disease is one of important disease of its output of harm, and rice sheath blight disease generally occurs in the country of the rice cultivations such as Asia, America, Africa, and is especially more general with rice district on the south the Changjiang river.Rice sheath blight disease is to be caused by Basidiomycotina bacterium fungi, and seedling stage to the fringe phase all can fall ill, and can cause Seed-Setting Percentage in Rice and thousand kernel weight significantly to reduce, even the plant lodging is withered, short-stalked variety is injured heavier, and it is high that wide, the popular frequency of area occurs, and loss often surpasses rice blast due to it.In the prior art, the rice sheath blight disease controlling medicament has caused very large environmental pollution take the missible oil of sterilization as main.Therefore, develop a kind ofly take water as medium, do not contain or contain less organic solvent, storing safety, microemulsion low in the pollution of the environment is imperative.
Propiconazole is a kind of interior absorption triazole bactericidal agent with protection and therapeutic action; can be absorbed by root, stem, leaf section; and can be soon in the plant body to conduction; the control sac fungi; the disease that basidiomycetes and imperfect fungus cause; the rice banded sclerotial blight disease is had preferably control efficiency, thereby the effect that plays sterilization, diseases prevention and cure the disease is that a kind of fungicidal spectrum is extensive, activity is high, sterilization speed is fast, the lasting period is long, the strong bactericide of interior suction conductivity.Disclose a kind of microemulsion of propiconazole such as CN1860878A, it comprises propiconazole 5 ~ 25%, organic solvent 5 ~ 30%, and cosolvent 5 ~ 15%, surfactant 10 ~ 30%, builder 0 ~ 10%, water adds to 100%.
Avermectin is a kind of antibiotics insecticidal/acaricidal agent of efficient, wide spectrum.It has stomach toxicity and action of contace poison to mite class and insect.Spray in leaf surface and can decompose rapidly dissipation, the insect that takes food harm in evil mite and the plant tissue is had long residual effect.Can be used for poultry, domestic animal endoparasite and ectoparasite and crop pests, such as the red worm of parasitism, diptera, coleoptera, Lepidoptera and pest mite etc., tetranychid, goitre mite and the various resistance aphid of the crops such as grain, fruit tree, vegetables had fine preventive effect.
Summary of the invention
The present invention seeks to find a kind of good drug efficacy, the less agricultural chemicals of preventing and treating rice sheath blight disease of environmental hazard.If the inventor considers disease by propagation such as aphid, evil mites, its state of an illness tends to increase the weight of.Therefore, the inventor considers to come and fungicide compounding by screening a kind of insecticidal/acaricidal agent, in the hope of further bringing into play the compounded preparation of pesticide of bactericide bactericidal action, being mixed by propiconazole and Avermectin found in experiment, in pest control, evil mite, can make its control efficiency to rice sheath blight disease more remarkable; In addition, the present invention is mixed into microemulsion with propiconazole with Avermectin, has also reduced the consumption of organic solvent, meets human environmental protection demand.
Therefore, the invention provides a kind of micro-emulsion insecticide, it is characterized in that, described micro-emulsion insecticide is by propiconazole and abamectin compounded obtaining.
In the present invention, preferably, described micro-emulsion insecticide comprises following component by weight percentage, propiconazole 1.0 ~ 10%, Avermectin 0.5 ~ 6%, solvent 5 ~ 30%, emulsifier 1 ~ 30%, antifreezing agent 0 ~ 5.0%, defoamer 0 ~ 2.0%, and surplus is water.
Further, described solvent is one or more in toluene, dimethylbenzene, methyl alcohol, ethanol, n-butanol, isopropyl alcohol and the cyclohexanol.Described emulsifier is alkylbenzenesulfonate, aliphatic alcohol sulfate, alkylphenol polyoxyethylene, alkyl phenyl phenol polyethenoxy ether, alkylphenol-polyethenoxy polyethenoxy ether, alkyl phenyl phenol polyethenoxy polyethenoxy ether, bitter edible plant sulfonic acid and formaldehyde, 1,2-di-n-butyl naphthalene-6-sodium sulfonate, in methoxyl group fatty acyl amido benzene sulfonic acid sodium salt, lignosulfonates, carboxymethyl cellulose salt class, alkylsulfonate, aliphatic alcohol sulfate, alkyl sulfate, oleate, dioctyl sulfosuccinate, dibutyl naphthalene sulfonate or the peregal one or more.Described antifreezing agent is one or more in ethylene glycol, propane diols, urea and the ammonium sulfate.Described defoamer is one or more in organosiloxane, polyethers, organic silicone, n-butanol and the n-octyl alcohol.Water among the present invention for example is running water.
The present invention is the corresponding preparation method that above-mentioned micro-emulsion insecticide is provided also, is specially: with solid-state insecticide Avermectin dissolution with solvents, then mix the oil phase that forms homogeneous with the liquid germicide propiconazole; Add the emulsifier mixing in the mixed process or after the process; Water is mixed the water that forms homogeneous with optional antifreezing agent and defoamer; Then pour water into oil phase, mixing obtains microemulsion.In this preparation method, preferably, the blending process behind the adding emulsifier is that 100 ~ 1000 rev/mins of lower stirrings were finished in 5 ~ 10 minutes in room temperature and rotating speed.
The application of micro-emulsion insecticide in preventing and treating rice sheath blight disease that the present invention also provides a kind of above-mentioned micro-emulsion insecticide or described preparation method to prepare.
