A method for controlling undesirable vegetation in growing areas of crop plants, which comprises allowing a composition comprising: a) a herbicidal compound A, which is Imazamox； and b) an adjuvant B, which is b2) an anionic surfactant that is selected from aliphatic monocarboxylates, aliphatic oligocarboxylates, sulfonamidocarboxylates, aliphatic or aromatic sulfates, polyether sulfates, amidopolyether sulfates, sulfated carboxylates, carbonic or carbonic acid sulfonates, , carboxylic esters or sulfonated carboxylic amides, esters of sulfosuccinic acid, polyether sulfonates, polyether phosphates or phosphate ester of polyalkoxylated fatty alcohol, polyether sulfate and polyalkoxylated derivatives of compounds of formula R1Xn, wherein the polyalkoxylate residue ends in a Y residue, and in where R1 is selected from aliphatic or aromatic residues having at least eight carbon atoms； X is selected from hydroxyl, -O- (C1-C6-alkyl), -O- (C3-C6-alkenyl), amine, amide, or ester； n is 1, 2, 3, 4, 5, or 6； and Y is selected from carboxylate, sulphonate, sulfate, phosphate, or phosphonate； and wherein the weight ratio of the herbicidal compound A and adjuvant B is between 2: 1 and 1:60； act on the plants to be controlled or on their habitat, and where the crop plant is selected from a) sunflowers that contain a herbicide tolerance feature of (1) the CLHA-Plus feature, which has an AHASL (large subunit of acetohydroxy acid synthase) with a substitution A122 (At) T, or (2) a variant of AHASL thereof that contains both the substitution A122 (At) T and a second substitution that may be one or more of P197Q, P197S, T203I , T203X, A205D, A205V, W574L, A653N, A653T, A653F, or A653V. b) sunflowers that contain two herbicide tolerance traits, both the CLHA-Plus feature (AHASL-A122 (At) T) and a second AHASL feature, which is selected from an AHASL with an A205 (At) V substitution or an AHASL with a replacement P197 (At) L.Un método para controlar la vegetación indeseable en zonas de cu
