The objectives of the 2007 Preemergence Crabgrass Control study were to identify which treatments provided at least 90% control of crabgrass, if preemergence applications of A15879A (pre-mix) provided equivalent control to a mesotrione and Barricade tank mix, and if A15879A caused any commercially unacceptable phytotoxicity.
