Tenacity® is a systemic preemergence and postemergence herbicide for the selective contact and residual control
of weeds in turfgrasses. When applied preemergence, weeds absorb Tenacity during emergence from the soil. Dry
conditions following application may reduce the preemergence activity.
Tenacity® is a systemic preemergence and postemergence herbicide for the selective contact and residual control
of weeds in turfgrasses. When applied preemergence, weeds absorb Tenacity during emergence from the soil. Dry
conditions following application may reduce the preemergence activity. If rainfall (0.15 inches) has not occurred
within 10 days after a preemergence application, activate with 0.15 inches of irrigation. When used postemergence,
susceptible weeds absorb Tenacity through foliar contact and soil absorption. 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 postemergence weed control. A non-ionic surfactant should be
added in postemergence applications.
Tenacity may cause temporary whitening of turfgrass foliage. In general, symptoms appear five to seven days after
application and last for several weeks. A repeat application to the same site causes less whitening of the plant
tissue.
Tenacity is an effective herbicide for weed control prior to or during seeding of certain turfgrasses during turf
renovation (see section on use in New Seedings). If used preemergence in established turf, tank mixtures with
preemergence herbicides such as Barricade® 65WG Herbicide are recommended for longer residual and broad
spectrum weed control.
