Abstract/Contents:"Research was conducted to determine the effects of mowing height and herbicide treatments for the control of annual grassy weeds in Kentucky bluegrass. The experimental site was a mature blend of Kentucky bluegrass located at The John Seaton Anderson Turfgrass and Ornamental Research Facility near Mead, NE. Prior to application of herbicide treatment, the area was core-aerated and a mixture of crabgrass and yellow foxtail broadcast over the site to insure adequate weed pressure...Results from the analysis of variance (AOV) indicated significant herbicide treatment differences on all evaluation dates. Mowing height differences were significant on the July 11 and August 10 evaluation dates. On both dates, plots which were mowed at 1" had significantly greater weed populations than those mowed at 2.5". Most pre-emergence treatments provided good early season control. As the season progressed, however, control diminished for May treatments, indicating a shorter residual for these compounds. Post-emergence treatments on untillered crabgrass (EPO ) indicated excellent control with the experimental PREMIX treatments at all rates tested."
