Per the label for Tenacity Herbicide, it is best to treat nimblewill with 2-3 applications which are 2-3 weeks apart. If the nimblewill is still green, then you can go ahead and retreat now. If it is already dormant, then it would be best to wait until it is green again to treat with herbicides.

When Tenacity Herbicide is used for post-emergent control of weeds the weeds are sprayed directly. According to the product label, when used postemergence, susceptible weeds absorb Tenacity through foliar contact and soil absorption. The 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.
Tenacity Herbicide should not be used if the seed you are putting down is more than 20% fine fescue.

Please refer to the product label for full application instructions.
