Re: Watering in Tenacity 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.Moreover, how long before tenacity is rainproof?
Re: Tenacity/Rain Proof 3 hours is fine. Not ideal, but generally fine for Tenacity, assuming a NIS was used. It should have about 75% effectiveness, maybe more. Give it two weeks if at all possible.
