The objectives of the 2009 BASF Herbicide Efficacy Trial were to compare the effectiveness of Drive XLR8 to Drive 75DF in order to demonstrate enhanced efficacy, and to compare Drive XLR8 to other postemergence crabgrass herbicides applied at a multi-leaf (2 to 4 leaf) stage and at a multi-tiller (1 to 2 tiller) stage.
