Tenacity Herbicide is a systemic pre-emergence and post-emergence herbicide for the selective contact and residual control of weeds in turfgrasses. When applied as a pre-emergent, weeds absorb Tenacity during emergence from the soil.  When used as a post-emergent, Tenacity weed killer is absorbed by susceptible weeds through foliar contact and soil absorption.
Once absorbed, Tenacity quickly translocation throughout the plant. Weed growth is suppressed soon after application, as photosynthesis is disrupted. Death of the plant usually occurs within two to three weeks.  Foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application is required after two to three weeks for improved post-emergence weed control.
