Example Embodiment

[0018] Example 1:

[0019] According to the technical scheme of the present invention, weigh 5% of pymetrozine powder, 10% of cyclohexanone, 10% of ethyl acetate, mix the three, and fully dissolve them, then add castor oil polyoxyethylene ether 5%, polyol Fatty acid esters and their ethylene oxide adducts 4%, dialkyl succinate sulfonate sodium salt 4%, sesame oil 3%, after fully stirring to dissolve, slowly inject water under stirring at 3000 rpm to make up 100%, to obtain a transparent 5% pymetrozine microemulsion.

Example Embodiment

[0020] Example 2:

[0021] According to the technical scheme of the present invention, weigh 15% pymetrozine raw powder, 15% ethyl acetate, 10% Solvesso200, mix the three, and after fully dissolve them, add 2% alkylphenol polyoxyethylene ether, polyol fat Acid ester and its ethylene oxide adduct 10%, sodium di-secondary octyl maleate sulfonate 4%, fatty alcohol sulfate 3%, double killing 3%, after fully stirring and dissolving, at 4000 rpm Slowly inject water to make up to 100% under stirring for a minute to obtain a transparent 15% pymetrozine microemulsion.

Example Embodiment

[0022] Example 3:

[0023] According to the technical scheme of the present invention, weigh 20% of the original pymetrozine powder, 10% of cyclohexanone, and 25% of N-octylpyrrolidone, mix the three, and after fully dissolving, add di-sec-octyl maleate Sodium sulfonate 13%, alkyl aryl phenol polyoxyethylene ether phosphate 6%, sodium sulfate 0.1%, alkyl amine oxide 1%, propynyl ether 2%, after fully stirring and dissolving, under stirring at 4000 rpm Slowly inject water to make up to 100% to obtain a transparent 20% pymetrozine microemulsion.

Abstract

The invention relates to a pymetrozine micron emulsion and a preparation method thereof. The pymetrozine micron emulsion includes the components by weight: 1-20% of pymetrozine, 5-40% of a solvent, 6-20% of an emulsifier, 1-5% of a penetrant, 1-5% of a synergist and the balance water. The invention discloses a preparation method of the pymetrozine micron emulsion. The pymetrozine micron emulsion can be used for the insect control of agriculture field nuisanceless production. The pymetrozine micron emulsion is stable in performance, high in insecticidal activity, and improved in efficacy, and reduces the dosage of medicament.

Description

Technical field [0001] The invention is a pesticide field, which involves a pyrine micro -emulsion and its preparation methods. Background technique [0002] Pyrephinone is a pyridine pesticide with high efficiency, low toxic, low residue, long -lasting period, and strong internal absorption. It is a new non -killer pesticide.Pests show an excellent prevention and treatment effect.Research using electrical penetrating graphs (EPG) technology shows that whether it is a bit, feeding or injection test, as long as aphids or livelings are exposed to pyrine, a degenerative obstruction effect is almost immediately generated, and the feeding is immediately stopped and eventually hungryDeath, and this process is irreversible. [0003] At present, the use of pyromone is mainly wettable powder. It produces a large amount of dust during the production of wettable powder, polluting the air, and use of dust pollution.Therefore, the development of new liquid preparations to reduce or eliminate ...
