CA 2643653

The present invention relates to new aqueous microemulsions containing organic pesticide compounds of limited water-solubility and to their use for plant protection, including seed and crop protection, and protection or non-living material. The aqueous microemulsions comprise a) at least one pyrethroid compound P; b) at least one organic solvent, selected from compounds of the formula I R1-(O-Alk)m-O-C(O)R2 (I) wherein m is 1, 2 or 3, R1 is H, C1-C6-alkyl or C(O)R3, R2 is hydrogen or C1-C4-alkyl, which may be unsubstituted or substituted with OH, Alk is C2-C6-alkylene, and R3 is hydrogen or C1-C4-alkyl, which may be unsubstituted or substituted with OH; c) at least one surfactant; and d) water.

La présente invention concerne de nouvelles microémulsions aqueuses contenant des composés organiques pesticides présentant une solubilité limitée dans l'eau ainsi que leur utilisation pour la protection des plantes, y compris la protection des semences et des cultures, et pour la protection de matériau non vivant. Les microémulsions aqueuses comprennent a) au moins un composé de pyréthroïde P; b) au moins un solvant organique, choisi parmi les composés de formule I R1-(O-Alk)m-O-C(O)R2 (I), dans laquelle m représente 1, 2 ou 3, R1 représente H, un alkyle en C1-C6 ou C(O)R3, R2 représente un hydrogène ou un alkyle en C1-C4, non substitué ou substitué par OH, Alk représente un alkylène en C2-C6 et R3 représente un hydrogène ou un alkyle en C1-C4, non substitué ou substitué par OH; c) au moins un tensioactif; et d) de l'eau.
