example 1

[0057] Fipronil 0.5%, triazophos 20.0%, N,N-dimethylformamide 0.5%, cyclohexanone 1.5%, epoxy soybean oil 3.0%, polyoxyethylene nonylphenol ether 1.0%, polyoxyethylene Put 3.0% ethylene polyoxypropylene block copolyether and 1.0% tallow ethoxyamine salt into the stirring tank, and after stirring evenly, a uniform and transparent oil phase is obtained, and the oil phase is pumped into a high-shear emulsifier. Put 3.0% sodium carboxymethylcellulose, 5.0% polyethylene glycol 400, and distilled water into another stirring tank to make up to 100%. After mixing evenly, a uniform water phase is obtained, and the water phase is poured into the head tank. Under high-speed shearing conditions, add the water phase to the oil phase dropwise, adjust the pH value to 4 and continue shearing for 10-30 minutes to obtain a 20.5% insecticidal aqueous emulsion containing fipronil and triazophos .

example 2

[0059] Fipronil 1.0%, triazophos 25.0%, N,N-dimethylacetamide 1.0%, diacetone alcohol 1.0%, cyclohexanone 2.0%, epichlorohydrin 2.0%, glycidyl ether 0.5%, Put 2.0% of alkylphenol polyoxyethylene ether and 4.0% of polyoxyethylene polyoxypropylene block copolyether into the stirring tank, and after stirring evenly, a uniform and transparent oil phase is obtained, and the oil phase is poured into the head tank. Put 1.0% sodium naphthalene sulfonate, 2.5% aluminum magnesium silicate, 4.0% polyethylene glycol, and distilled water into another stirred tank to make up to 100%, and after mixing evenly, a uniform water phase is obtained, and the water phase is pumped into the Shear emulsifier. Under high-speed shearing conditions, slowly add the oil phase to the water phase, adjust the pH value to 4.5 after adding, and continue shearing for 10-30 minutes to obtain 26% insecticidal water containing fipronil and triazophos emulsion.

example 3

[0061] Fipronil 1.0%, triazophos 30.0%, N,N-dimethylformamide 0.5%, n-butanol 0.5%, diacetone alcohol 2.0%, cyclohexanone 2.0%, triphenyl phosphite 1.5% , pentaerythritol 0.5%, fatty alcohol ethoxylate 2.0%, polyoxyethylene polyoxypropylene block copolyether 3.0%, polyoxyethylene ether phosphate 1.0%, alkylphenol formaldehyde resin polyoxyethylene ether 2.0% input Put it into the stirring tank, and after stirring evenly, a uniform and transparent oil phase will be obtained, and the oil phase will be poured into the high-level tank. Put 1.0% organic bentonite, 0.05% xanthan gum, 3.0% propylene glycol, and distilled water into another stirred tank to make up to 100%, and mix well to obtain a uniform water phase. Under the condition of mechanical stirring, slowly add the oil phase in the head tank into the water phase, and continue to stir for 10-20 minutes after the addition to obtain a coarse emulsion; use a high-pressure homogenizer to homogenize the coarse emulsion once, and ...

Abstract

The invention discloses a compound disinsection water emulsion which contains fipronil and triazophos and a preparation method thereof. The water emulsion comprises 0.5-3 percent of the fipronil, 20-40 percent of the triazophos, 5-12 percent of emulsifier, 0-3 percent of stabilizer, 2-10 percent of cosolvent, 0-5 percent of antifreeze, 0-3.0 percent of thickener and the rest is dispersion medium water, which are dispersed evenly by a high-speed cutting and mixing emulsifier or are homogenized by a high-pressure homogenizer, thus obtaining the invention. The invention does not have insecticide resistance, has high efficacy and special effects on preventing rice stem borers, yellow rice borers, pink rice borers, rice leaf rollers, plutellid moths and diamondback moths; the invention also can control leafhoppers, plant hoppers, flies and coleopteran pests at the same time. The invention adopts the water as the dispersion medium and has the advantages that the invention does not pollute the environment, has no crystallization phenomena after two-year storage and has long shelf life; besides, the invention is not inflammable, can be safely stored and transported and has simple production technique; compared with using the fipronil independently, the cost of the invention can be reduced greatly.

Description

Technical field: [0001] The invention relates to a pesticide insecticide, in particular to a compound insecticidal aqueous emulsion containing fipronil and triazophos and a preparation method thereof. Background technique: [0002] As one of the 10 key varieties of triazophos determined by the National Development and Reform Commission and the Ministry of Agriculture to replace 5 highly toxic pesticides including methamidophos, monocrotophos, methyl parathion, parathion and omethoate It is a broad-spectrum insecticide and acaricide, and also has nematicide effect. It can be used to control lepidopteran pests and aphids on fruit trees, vegetables, and cereal crops. It has a huge market prospect. One of the leading varieties of rice borer. According to statistics, as of September 2006, there were 547 registrations of triazophos-containing insecticides in China, of which 522 were emulsifiable concentrate products, accounting for 95.4%. Crystallization is easy to occur, and th...
