NOVELTY - Pesticidal chlorantraniliprole microemulsion comprises (in wt.%) chlorantraniliprole, emulsifying agent, penetrating agent, stabilizing agent, cosolvent and deionized water. The emulsifying agent is alkylbenzene naphthalenesulfonate, alkyl phenol polyoxyethylene ether phosphate, ethoxylated/propoxylated diphenylphenol, styrene phenol polyoxyethylene ether, sodium N-dodecyl- beta -aminopropionate, sodium alginate, natural carboxylate, polyoxyethylene styrene phenol ether and/or tea saponin. The penetrating agent is e.g. sulfonate sodium salt of succinic acid ester.    USE - The microemulsion is useful for controlling pests on vegetable, beet and cotton.    ADVANTAGE - The microemulsion: does not harm the environment, humans, livestock and beneficial organisms; is economical and has a simple production; and is suitable for large-scale industrial production.    DETAILED DESCRIPTION - Pesticidal chlorantraniliprole microemulsion comprises (in wt.%) chlorantraniliprole (0.1-60), an emulsifying agent (3-27), a penetrating agent (2-15), a stabilizing agent (1-10), a co-solvent (2-40) and deionized water (15-79). The emulsifying agent is alkylbenzene naphthalenesulfonate, alkyl phenol polyoxyethylene ether phosphate, ethoxylated/propoxylated diphenylphenol, styrene phenol polyoxyethylene ether, sodium N-dodecyl- beta -aminopropionate, sodium alginate, natural carboxylate, polyoxyethylene styrene phenol ether and/or tea saponin. The penetrating agent is sulfonated succinic acid octo sodium salt, octo phosphate sodium salt and/or laurocapram. The co-solvent is ethanol, n-butyl alcohol, glycol, propylene glycol, glycerol, acetone, cyclohexanone, pyrrolidone and/or ethyl acetate. The stabilizing agent is carbamide, monopotassium phosphate, sodium sorbate, 3-chloro-1,2-epoxypropane and/or tolyl glycidyl ether. An INDEPENDENT CLAIM is also included for producing the pesticidal chlorantraniliprole microemulsion, comprising uniformly agitating and mixing chlorantraniliprole, emulsifying agent, co-solvent and stabilizing agent in a high-speed shearing machine, adding deionized water, agitating and mixing the materials uniformly, allowing to stand for 5-13 hours, heating the materials to 45-65 degrees C and uniformly agitating the materials to obtain the pesticidal chlorantraniliprole microemulsion.
