Abstract

L'invention concerne une composition de pesticide liquide qui contient un pyriproxifène, une clothianidine, un solvant organique hydrophobe, un premier tensio-actif et une eau, dans lequel un liquide obtenu par dissolution dudit pyriproxifène dans ledit solvant organique hydrophobe, est dispersé dans l'eau, et dans lequel ladite clothianidine se trouve en suspension. Ledit premier tensio-actif est constitué d'une ou plusieurs sortes de composants choisies dans un groupe constitué d'un produit d'addition d'oxyde d'éthylène d'acide gras, d'un produit d'addition d'oxyde d'ester éthylène d'acide gras d'alcool polyvalent et d'un copolymère séquencé d'oxyde d'éthylène et oxyde de propylène, et présente une valeur HLB supérieure ou égale à ５,０ et inférieure ou égale à ２０,０. Le rapport de la masse (Ｗ２) dudit solvant organique hydrophobe pour la masse (Ｗ１) dudit pyriproxifène, est supérieur ou égal à １,０ et inférieur ou égal à ６,０. Le rapport de la masse totale (Ｗ４) dudit pyriproxifène, de ladite clothianidine et dudit solvant organique hydrophobe pour la masse (Ｗ３) dudit premier tensio-actif, est supérieur ou égal à ２,０ et inférieur ou égal à ８０,０.
