COMPOSITIONS OF TOPRAMESONE MICROEMULSIONS Russian patent published in 2023 - IPC A01N25/04 A01N25/22 A01N25/30 A01N41/10 A01N43/56 A01N43/80 A01P13/00 

FIELD: agriculture.

SUBSTANCE: aqueous herbicidal compositions. Herbicidal microemulsion composition containing an oil phase and an aqueous phase, in which the oil phase contains topramesone or an agriculturally acceptable salt thereof, a first solvent, a second solvent that is different from the first solvent, a first emulsifier-surfactant (emulsifier-surfactant), the aqueous phase contains a stabilizer and a second emulsifier-surfactant, which differs from the first emulsifier-surfactant. The solvent is selected from benzyl ether and methyl oleate, the emulsifier-surfactant is selected from glyceryl oleate and a C8-C10 alkyl carbon alkyl polyglucoside with a degree of polymerization of 1.5, and the stabilizer is polyethylenimine, triethanolamine or a mixture thereof.

EFFECT: proposed microemulsion herbicidal composition is suitable for use in the form of a ready-to-use solution or in the form of a spray, has high storage stability, and high herbicidal efficiency due to the preservation of small droplet size.
