Zusammenfassung:Amine salts of 3-phenyl-6-halo-4-hydroxypyridazines of the formula: in which X is a chlorine or bromine atom, R1 is an alkyl group containing up to 14 carbon atoms, which group may be substituted by a hydroxy group, an alkoxy group containing up to 10 carbon atoms, cyano group, amino group or lower mono- or lower dialkylamino group, an alkenyl group containing up to 6 carbon atoms or a cycloalkyl group containing 5, 6 or 7 carbon atoms, and R2 and R3 have the same meaning as R1 or each is a hydrogen atom, or R1 and R2 together with the nitrogen atom of the amine form a 5- or 6-membered heterocyclic group which may also contain oxygen and which may be mono- or di- substituted by alkyl, and herbicidal compositions containing them.
