Abstract/Contents:CONCLUSION: "Depending on conditions, herbicidal activity [of PROGRASS] on established Poa annua may be observed within a week or two following application. In some cases however, control may not be evident until the following spring. Experiences from research and commercial programs indicate strongly that better results are achieved with repeat applications during the first two years, especially in areas of heavy infestation. By the third year the number of treatments can be reduced, and applications can be made on an as-needed basis."
