Abstract: 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.
