1. A composition, comprising:
(a) a pyridine carboxylate herbicide defined by Formula (I):

OG Complex Work Unit Chemistry
wherein:
R1 is cyanomethyl or propargyl;
R2 and R2′ are independently hydrogen, C1-C6 alkyl, formyl, alkoxycarbonyl, or acyl;
R3, R3′, R3″, and R3″′ are independently hydrogen, halogen, C1-C4 alkyl, C1-C4 haloalkyl, C1-C3 alkoxy, or C1-C3 haloalkoxy;
or an agriculturally acceptable salt thereof; and
(b) an HPPD inhibitor herbicide selected from the group consisting of benzobicyclon, isoxaflutole, mesotrione, pyrazolynate, sulcotrione, tembotrione, topramezone, an agriculturally acceptable salt thereof, an agriculturally acceptable ester thereof, and combinations thereof;
wherein the weight ratio of the pyridine carboxylate herbicide in g ae to the HPPD inhibitor herbicide in g ai is from about 1:100 to about 5:1.
