Application of Certainty*, Manor*, Monument*, Revolver*, TranXit, Kerb*, and flazasulfuron in early June eliminated most ryegrass in one month with the onset of high summer temperatures. Certainty at 0.06 lb a.i./A, Manor at 0.012 lb a.i./A, Monument at 0.0047 lb a.i./A, Revolver at 0.008 lb a.i./A, TranXit at 0.0078 lb a.i./A, and flazasulfuron at 0.0039 lb a.i./A performed equivalent to higher rates to effectively remove ryegrass when applied in June. The herbicides at the lower rate range were not as effective in early May when ryegrass tended to regrow in cooler temperatures. Spring transition was achieved by applying higher rates of TranXit* at 0.031 lb a.i./A and flazasulfuron at 0.0156 lb a.i./A in early May to completely remove perennial ryegrass. Kerb at 1.0 lb a.i./A was effective in removing 80% of the ryegrass with a May application and 90% in June.
