Have applied Tenacity once three weeks ago, but if September - February is nimblewill dormancy, should the remaining two or three applications wait until say March 2019?
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.
