I do professional maintenance and used Tenacity to control bentgrass in lawns? I did 3 applications at 2 week intervals and used the proper rate. It seemed like it was working and the bentgrass was bleached white but after a few weeks it seems to have completely come back. Does it only burn down the top growth?
Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications. Late summer/Fall applications will be more effective than Spring applications.
