The product label advises on waiting 7 days after applying Tenacity Herbicide if you will be applying an organophosphate or carbamate insecticide as it could cause potential injury to the turf. Other insecticides not in either of those classes would be fine to apply 24 hours after the application of Tenacity. For example, Bayer's Dylox 6.2 Granules or Dylox 420 SL both have an active ingredient of Trichlorfon which is considered an organophosphate, therefore you should wait the window of at least 7 days before you apply Dylox 6.2 or Dylox 420 SL to the area that has been treated with Tenacity Herbicide. Other examples of organophosphate or carbamate insectides contain Malathion, Parathion, Diazinon, Fenthion, Dichlorvos, Chlorpyrifos, & Ethion.
