The invention relates to an emulsifiable concentrate comprising an active ingredient being a dinitroaniline compound, preferably selected from the group consisting of pendimethalin, trifluralin and mixtures thereof. The emulsifiable concentrate of the invention avoids crystallization at low temperature when the concentration of the active ingredient is high. Accordingly, the emulsifiable concentrate comprises a diester co-~solvent having the following formula R1OOC-(CH2)n-COOR2, wherein R1 and R2, identical or different, are C1-C10, preferably C1-C6, linear or branched, alkyl, aryl, alkaryl or arylalkyl groups, and n is an average number of from 2 to 4.
L'invention concerne un concentré émulsifiable comprenant un principe actif qui est un composé de dinitroaniline, de préférence sélectionné dans le groupe constitué de pendiméthaline, de trifluraline et de mélanges de ces derniers. Le concentré émulsifiable selon l'invention permet d'éviter la cristallisation à basse température lorsque la concentration du principe actif est élevée. En conséquence, le concentré émulsifiable comprend un co-solvant diester de formule R?1¿OOC-(CH¿2?)¿n?-COOR?2¿, dans laquelle R?1¿ et R?2¿, identiques ou différents, représentent des groupes C¿1?-C¿10?, de préférence C¿1?-C¿6?, linéaires ou ramifiés, alkyle, aryle, alkaryle ou arylalkyle, et n représente un nombre moyen compris entre 2 et 4.
