The objectives of this study were to evaluate the level of crabgrass control with different Pendulum (pendimethalin) formulations(BASF) compared with other preemergence products and to determine if a new Dimension (dithiopyr) formulation, Dimension EW, performs as well as current dithiopyr formulations(Dow). Data were taken to determine if any of the treatments caused phytotoxicity to the ‘common’ Kentucky bluegrass.
