EndRun Herbicide with Trimec is a broadleaf weed killer using a combination of 2,4-D, Dicamba, and MCPP-P and already contains a surfactant for better coverage and faster burndown of the weed. There are no pre-emergent qualities to EndRun Herbicide with Trimec like there is with Tenacity.
Tenacity uses the active ingredient Mesotrione and labeled for both broadleaf and grassy weeds and also provides pre and post emergent control of listed weeds. Tenacity is also the only pre emergent that can be used at the same time of overseeding for cool season turfgrasses. For post emergent applications, Tenacity requires a non ionic surfactant to be added for best results.
