We did a conversion on our practice course from a contaminated ultr-dwarf bermuda to tifdwarf. We sprayed them twice with Round-up, aerified and topdressed, then applied Basamid at the high rate. We followed the irrigation instructions. Most greens are 100% after two years. We do have some spots in 3 of 9 greens.
