The objectives of the formulation-bridging study were to identify if the new 4L formulation of prodiamine provided crabgrass control comparable to the current 4FL formulation, identify if there is a difference in spraying characteristics between the treatments after they are allowed to set for 24 hours, and evaluate if the new formulation is safe to turf.
