Embodiment 1

[0019] Thiofluoroxime ether 10 grams, avermectin 0.1 grams, castor oil polyoxyethylene ether 6 grams, calcium dodecylbenzenesulfonate 2 grams, epichlorohydrin 2 grams, N, N-dimethylformamide 6 grams, xylene is supplemented to 100 grams, and all components are mixed and dissolved in proportion to become the emulsifiable concentrate preparation of thiofluoroxime ether+abamectin.

Embodiment 2

[0021] Thiofluoroxime ether 15 grams, emamectin benzoate 0.01 grams, alkylphenol polyoxypropylene ether 8 grams, calcium dodecylbenzenesulfonate 2 grams, BHT 3 grams, methanol 6 grams, solvent oil to 100 grams, all groups Parts are mixed and dissolved in proportion to become an emulsifiable concentrate preparation of thiofluoroxime ether + emamectin benzoate.

Embodiment 3

[0023] Thiofluoroxime ether 20 grams, spinosad 0.05 grams, castor oil polyoxyethylene ether 5 grams, phenethylphenol polyoxyethylene ether 7 grams, calcium dodecylbenzenesulfonate 2 grams, epoxidized soybean oil 3 grams , the above components are heated and melted to form an oil phase; 3 grams of ethylene glycol, 0.2 grams of xanthan gum, and water to make up to 100 grams of the total mass, stir to form a water phase, drop the oil phase into the water phase, and stir while adding , the dropping speed is 4 drops / second, and the stirring speed is 100 revolutions / second, which becomes the aqueous emulsion preparation of thiofluoroxime ether+spinosyn.

Abstract

The present invention discloses a combination of macrolides insecticide and insecticide of Sufluoxime, wherein the macrolides insecticide is spinosad, avermectin, the derivative thereof, etc., and the Sufluoxime is 1-(3-fluoro-4-chlorophenyl)-2-methylthioethanone-O-(2-hydroxymethyl-3-methyl) aether. The various surfactants and additives such as carrier, thickening agent, stabilizing agent, antifreeze agent, antifoaming agent, adhesive and the like are added to prepare an insecticidal composition in dosage forms of missible oil, aqueous emulsion, microemulsion, suspending agent, granular formulation, water dispersible powder or dispersible granula, etc. The insecticidal composition has characteristics of evident synergism, resistance delay, widening the spectrum of insect disinfestation, etc., and has disinfestation effect to the destructive insect in the disinfestation range of two normal insecticides.

Description

technical field [0001] The invention relates to an insecticidal composition of the insecticide thiofluoroxime, especially an insecticidal composition compounded with a macrolide insecticide and a preparation method thereof. Background technique [0002] Thiofluoroxime ether is a new insecticide with obvious insecticidal activity invented by Hunan Research Institute of Chemical Industry. It belongs to oxime ether pyrethroid insecticides. Fluoro-4-chlorophenyl)-2-methylthioethanone oxime-O-(2-methylbiphenyl-3-methyl)ether [0003] Its structural formula is: [0004] [0005] The technical product of thiofluoroxime ether is a white to light yellow solid, which is a low-toxicity insecticide, and can be used to prevent and control various pests on tea, citrus, and vegetables. The dosage is 3-6g a.i. / mu. There are two domestic patents related to thiofluoroxime ether, both of which were applied by Hunan Research Institute of Chemical Industry. One was applied on September 10, ...
