CA 2737098

The present invention relates to liquid active ingredient concentrates that can be emulsified in water, said concentrates comprising at least a herbicidal dinitroaniline, in particular pendimethalin, and at least an imidazolinone herbicide, in particular Imazomax. The composition comprises: a) 100 to 400 g/l of at least one herbicidal dinitroaniline (component a); b) 5 to 100 g/l of at least one imidazolinone herbicide in the form of the ammonium salt or substituted ammonium salt thereof (component b); c) 20 to 100 g/l water (component c); d) 15 to 150 g/l of at least one anionic surface active substance comprising at least one sulfonic acid group in the form of the sodium, potassium, ammonium or substituted ammonium salt of said surface active substance, (component d); e) 5 to 100 g/l of at least one polymeric, non-ionic surface active substance comprising at least a polyethylene oxide group and at least a radical selected from poly-C5-C4-alkylene oxide groups (component e); f) 50 to 250 g/l of at least one non-ionic surface active substance selected from ethoxylated fatty acid esters of polyhydroxyl compounds, alkylpolyglucosides, ethoxylated C4-C16 alkyl phenols and ethoxylated C5-C22- alkanols (component f); g) at least one hydrocarbon solvent to make 1 I (component g); wherein the amounts of components a) to f) indicated in g/l are based on the total volume of the active ingredient concentrate.

L'invention concerne des concentrés de substances actives liquides, émulsifiables dans l'eau, qui contiennent au moins une dinitroaniline herbicide, notamment la pendiméthaline, et au moins un herbicide à base d'imidazolinone, notamment l'imazamox. La composition contient: a) 100 à 400 g/l d'au moins une dinitroaniline herbicide (composante a); b) 5 à 100 g/l d'au moins un herbicide à base d'imidazolinone sous forme de son sel d'ammonium ou de son sel d'ammonium substitué (composante b); c) 20 à 100 g/l d'eau (composante c); d) 15 à 150 g/l d'au moins une substance tensioactive anionique contenant au moins un groupe d'acide sulfonique, sous forme de son sel de sodium, de potassium, d'ammonium ou de son sel d'ammonium substitué (composante d); e) 5 à 100 g/l d'au moins une substance tensioactive non ionique polymère contenant au moins un groupe d'oxyde de polyéthylène et au moins un reste sélectionné parmi les groupes d'oxyde de polyalkylène C3-C4 (composante e); f) 50 à 250 g/l d'au moins une substance tensioactive non ionique, sélectionnée parmi des esters d'acide gras éthoxylés de composés polyhydroxy, des alkylpolyglucosides, des alkylphénols C4-C16 éthoxylés et des alcanols C8-C22 éthoxylés (composante f); g) au moins un solvant d'hydrocarbure ad 1 I (composante g), les quantités indiquées en g/l des composantes a) à f) se rapportant au volume total du concentré de substances actives.
