In one answer about watering you state it does not need to be watered in because it is mixed with water;...
however, in another answer you state it does, indeed need to be watered in asap. could you please clarify which is correct. Thank you.
Tenacity is a systemic preemergence and postemergence herbicide for the selective contact and residual control of weeds in turfgrasses. When applied as a preemergent, 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 as a postemergent, susceptible weeds absorb Tenacity through foliar contact and soil absorption. Therefore, you should water in Tenacity when using it as a preemergent herbicide but it does not need to be watered in when using it as a postemergent herbicide.
