| Abstract/Contents: | "Two studies were conducted on a mature stand of perennial ryegrass (Lolium perenne L.) at the Valentine Turfgrass Research Center, Penn State University, University Park, Pa. The objective of the studies was to evaluate the efficacy of postemergence herbicides for the control of smooth crabgrass (Digitaria ischaemum). All studies were a randomized complete block design with three replications. Both studies had an individual plot size of 21 square feet and were maintained at one half inch using a reel mower with clippings returned to the site. Irrigation was applied on an as needed basis to simulate golf course fairway conditions. For the pre/post study, all of the treatments were applied on June 13, 2001, for the post study, all of the treatments were applied on July 16, 2001. In both experiments, a three foot CO2 powered boom sprayer calibrated to deliver 40 gpa with two, flat fan, 6504 nozzles at 40 psi was used for application. Granular treatments were applied with a shaker jar. Evaluations of the pre/post study revealed that only Dimension (dithiopyr) 1EC at 0.5 lbs ai/A, XF00090 FG 0.164G at 0.5 lbs ai/A, XF 00091 FG 25G at 0.38 lbs ai/A, Dimension 40WP at 0.5 lbs ai/A and XF00090 FG 0.164 at 0.38 lbs ai/A controlled crabgrass within a range of 77% to 83%. This is slightly below the level of commercial acceptability (85% control). None of the other treatments in the study exceeded 67% control. For the post study, two treatments, Acclaim Extra (fenoxaprop-p-ethyl) 0.57EW at 0.17 lbs ai/A and Acclaim Extra 0.57EW at 0.12 lbs ai/A combined with an additive provided 85% control. Acclaim Extra 0.57EW at 0.09 and 0.12 lbs ai/A and Acclaim Extra 0.57EW at 0.07, 0.09 and 0.12 lbs ai/A combined with MacroSorb Foliar at 2 oz/M provided control in the range of 80% up to 83% of smooth crabgrass. None of the remaining treatments provided control above 78%." |
