9. The composition according to claim 3 , wherein (A):(B) are in a weight ratio of about 1:1.5.

10. The composition according to claim 9 , wherein (A):(B) are in a weight ratio of 1:1.5.

11. A composition according to claim 1 , wherein component (B) is tembotrione, or a herbicidally effective salt.

12. A composition according to claim 1 , wherein component (B) is topramezone, or a herbicidally effective salt.

13. A composition according to claim 1 , wherein the ratio of (A):(B) is between about 2.5:1 to 1.1.5.

14. A composition according to claim 13 , further comprising a safener selected from cloquintocet-mexyl or a salt thereof, cyprosulfamide and N-isopropyl-4-(2-methoxy-benzoylsulfamoyl)-benzamide.
