An emulsifiable concentrate comprising a benzoic acid herbicide in acid form dissolved in an amide solvent and an amide solvent and an amine emulsion stabiliser. Preferably: &#x2022;the benzoic acid herbicide is selected from TBA, chloramben and dicamba acid, &#x2022;the amine is of the formula (I) NRRRwhere wherein R, Rand Rare independently selected from the group selected from hydrogen; Cto Calkyl; Cor Ccycloaliphatic optionally substituted with from one to four Cto Calkyl groups and/or an amino-Cto Calkyl group; Cto Calkyl substituted with a substituent selected from the group consisting of hydroxyl, Cto Calkoxy, amino, (Cto Calkyl)amino and di-(Cto Calkyl)amino; and the group wherein two of R, Rand Rtogether form a ring of 5 or 6 constituent ring members selected from methylene, &#x2014;O&#x2014;, &#x2014;N(H)&#x2014; and &#x2014;N(Cto C-alkyl) and the other of R, Rand Ris selected from hydrogen, Cto Calkyl and Cto Calkyl substituted with a substituent selected from the group consisting of hydroxyl, Cto Calkoxy, amino and (Cto Calkyl)amino; and wherein at least one of R, Rand Ris other than hydrogen, and &#x2022;the amide solvents are of the formula (II) R&#x2014;CON&#x2014;RRwhere R is selected from the group consisting of hydrogen and Cto Chydrocarbyl, and Rand Rare is selected from the group consisting of Cto Chydrocarbyl and may together from a ring incorporating the nitrogen of the amide comprising 4 or 5 methylene groups.
