2. The herbicidal composition according to claim 1 , wherein the second herbicide is selected from sulfentrazone, pethoxamid, pyroxasulfone, and 4-(4-fluorophenyl)-6-(2-hydroxy-6-oxocyclohexane-1-carbonyl)-2-methyl-1,2,4-triazine-3,5(2H,4H)-dione; including and C 1-8 -alkyl esters or salts thereof.
3. The herbicidal composition according to any one of the preceding claims, wherein the first herbicide is beflubutamid enriched with respect to the (−)-enantiomer.
4. The herbicidal composition of any one of the preceding claims further comprising at least one formulation component selected from formulation agents for emulsifiable concentrate formulations, suspension concentrate formulations, and capsule suspension formulations.
5. A method of controlling undesired vegetation in a crop, wherein the method includes applying to the locus of the vegetation a herbicidally effective amount of a herbicidal composition according to any one of the preceding claims.
6. The method according to claim 5 , wherein the undesired vegetation is present together with a crop selected from wheat, barley, rye, triticale, corn, soybean and rice.
7. The method according to any one of claims 5 or 6 , wherein the herbicidal composition comprising beflubutamid in combination with sulfentrazone, and wherein beflubutamid is applied in an amount of 30-400 g ai/ha, or 45-320 g ai/ha, or 60-250 g ai/ha, and sulfentrazone is applied in an amount of 15-340 g ai/ha, or 20-270 g ai/ha, or 25-210 g ai/ha.
