Per the manufacturer, " Tenacity has been tested in tank mixtures with Barricade 65WG Herbicide (prodiamine), Vanquish® (dicamba), Turflon® ester (triclopyr), Spotlight™ (fluroxypyr), Quicksilver™ (carfentrazone), Basagran® (bentazon), Princep® (simazine), and AAtrex® (atrazine) for safety and efficacy on turfgrasses. Tenacity must be applied at reduced rates (4 fl. oz./A or less) if tank mixed with atrazine, bentazon or simazine. Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas. See product labels for directions and precautions."
