NOVELTY - Self-micro-emulsifying triazophos cream, comprises (in weight%) triazophos (10-40), surfactant (1-30), stabilizer (1-10) and solvent (remaining quantity).    USE - The triazophos cream is useful as an organophosphorus insecticide, acaricide and nematocide for controlling e.g. noctuids, plant nematodes, pine moths, Lepidoptera pests in fruit trees, Aphididae in cereals and fruit and Agrotis sp. and other cutworms.    ADVANTAGE - The self-micro-emulsifying triazophos cream has high effect and broad spectrum activity, and is environment-friendly.    DETAILED DESCRIPTION - Self-micro-emulsifying triazophos cream, comprises (in weight%) triazophos (10-40), surfactant (1-30), stabilizer (1-10) and solvent (remaining quantity). The solvent is ethanol, propanol, butyl alcohol, isobutyl alcohol, amyl alcohol, hexanol, heptanol, octanol, iso-octanol, cyclohexanone, pentane, hexane, cyclohexane, heptane, octane, iso-octane, petroleum ether, N-methyl pyrrole menthanone, N-octyl pyrrole menthanone, bi-12C alkyl pyrrolizidine-2,5-diketoethane, bi-12C alkyl pyrrolizidine-2,5-dialkyl hexanone, 70# solvent naphtha, 90# solvent naphtha, 120# solvent naphtha, 180# solvent naphtha, 190# solvent naphtha, 200# solvent naphtha or 6-18C alkyl methyl ester. The surfactant is chosen from polyoxyethylene polyoxypropylene block copolymer, triphenyl ethylphenol polyoxyethylene polyoxypropylene block copolymer, fatty alcohol polyoxyethylene ester, phenylethyl phenol polyoxyethylene formaldehyde condensate, castor oil polyoxyethylene ester, alkyl polyoxyethylene formaldehyde condensate, alkyl polyoxyethylene ester organic phosphate, dodecyl benzene sulfonic acid sodium, dodecyl benzene sulfonic acid calcium, dodecyl sulfonic acid sodium, dodecyl vitriol sodium, lauryl alcohol polyoxyethylene sodium sulfate, sorbitan fatty acid ester, sodium ligno sulfonate, Tween 20 (RTM: polysorbate 20), Tween 60 (RTM: polyethylene glycol sorbitan monostearate), Tween 65 (RTM: polyoxyethylene sorbitan monooleate), Tween 80 (RTM: polysorbate 80), Tween 85 (RTM: polyoxyethylene sorbitan trioleate), Span 20 (RTM: sorbitan monoester), Span 40 (RTM: sorbitan monoester), Span 60 (RTM: sorbitan monoester), Span 80 (RTM: sorbitan monoester) and alkylphenol polyoxyethylene ester. The stabilizer is chosen from epicholorhydrin, soybean oil epoxide, triphenyl phosphate, tributyl phosphate, hydroquinone, sulfuric acid, phosphoric acid, acetic acid, metacetonic acid, butyric acid, valeric acid, acetic anhydride, ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, glycerol propanetriol and polyglycol. An INDEPENDENT CLAIM is included for method for preparing the self-micro-emulsifying triazophos cream, comprising dissolving triazophos in solvent, dispersing well to obtain mixing solution of triazophos, adding surfactant into triazophos solution and blending the mixture to obtain evenly dispersed mixture, adding stabilizer into mixture, and whipping the mixture well to obtain reddish brown triazophos cream.
