Abstract

La présente invention porte sur un concentré pesticide émulsifiable contenant du 2-[(2-fluoro-5-trifluorométhyl)phénylthio]-2-[3-(2-méthoxyphényl)-2-thiazolydinylidène]acétonitrile, un solvant organique hydrophobe contenant de l'oxalate de diéthyle, un solvant organique hydrophile et un tensioactif, le rapport en poids de l'oxalate de diéthyle sur le solvant organique hydrophile étant compris entre 3 : 7 et 9 : 1. Le concentré pesticide émulsifiable selon l'invention présente une excellente stabilité de stockage et une excellente stabilité d'émulsion lorsqu'il est dilué dans de l'eau.
