• Velocity* Herbicide for Poa annua Control in Turf

      Umeda, Kai; Kopec, David M. (College of Agriculture and Life Sciences, University of Arizona (Tucson, AZ), 2009-02)
      Velocity* at 20 g a.i./A provided P. annua control better than at 10 g a.i./A. Velocity at 20 or 30 g a.i./A offered similar P. annua control with a single application. Velocity at 20 g a.i./A with the addition of non-ionic surfactant Latron CS-7* or Primo*, P. annua control was almost similar to that of Prograss* at 80%. Velocity at 10 g a.i./A combinations or at 20 g a.i./A without additives gave less than 75% control.
