| Abstract/Contents: | "This study was conducted on a mature stand of `Penneagle' creeping bentgrass (Agrostis stolonifera) and annual bluegrass (Poa annua) at the Valentine Turfgrass Research Center, Penn State University, University Park, PA. The objective of the study was to determine if summer and fall applications of Trimmit and Primo MAXX could eliminate annual bluegrass under fairway conditions over a two year period. This study was a randomized complete block design with three replications. Treatments were applied on May 30, June 27, July 18, Aug 14, Sept 13, Oct 12, 2001, April 16, May 15, July 10, July 31, September 10, and October 9, 2002 using a three foot CO2 powered boom sprayer calibrated to deliver 40 GPA using two, flat fan, 11004 nozzles at 40 PSI. The test area was maintained at 0.5 inches using a triplex reel mower clippings collected. The test site was treated similar to a fairway with respect to irrigation and fertility. Ratings of the percent change in annual bluegrass population were taken on May 13, 2002 and May 8, 2003. Annual bluegrass increased in the nontreated check (34.4 and 58.3% respectively), but increased significantly more in plots treated with Primo MAXX alone (100 and 91.7% respectively). Plots receiving Trimmit plus Coron had the greatest reduction of annual bluegrass, but not significantly more than those that received Trimmit alone. It should be noted that, from a turf color/quality perspective, when Trimmit was supplemented with Coron, the treated turf had higher quality than turf without a Coron supplement. There did not appear to be any advantage in annual bluegrass reduction by including an October application of Trimmit as part of the management strategy." |
