STABLE LIQUID PESTICIDAL COMPOSITIONS Russian patent published in 2007 - IPC A01N25/04 A01N25/02 A01N57/20 A01P13/00 

FIELD: agriculture.

SUBSTANCE: microemulsion composition of aqueous pesticidal composition contains pesticidal component comprising water-soluble pesticide dissolved in aqueous medium, wherein said pesticide contains glyphosate, or salt thereof, or ester in concentration which is biologically effective when composition is diluted and applied on pesticide-sensitive plant foliage; water-immiscible organic solvent having water solubility less than 10 % (mass/mass); and surfactant containing one or more cationic surfactants and stabilizer, wherein surfactant concentration is sufficient to provide acceptable heat stability of microemulsion in such a manner that said microemulsion has cloud point at least 50°C and crystallization point not higher than -10°C, wherein stabilizer includes one or more amine or quaternary ammonium salts having C₄-C₁₆-alkyl or aryl substituent and not more than ten ethyleneoxide bonds and presents in amount which increases compatibility abovementioned surfactant with pesticide.

EFFECT: composition of increased stability and decreased viscosity.
