It is not recommended to mix certain insecticides, herbicides, or fungicides with Tenacity Herbicide. You should wait to apply insecticides 7 days after treating with Tenacity Herbicide to avoid potential turf injury. Other ingredients in the fungicides or herbicides would be fine to use at the same time if there are no resttrictions on the product label.
