| Abstract/Contents: | "Two separate studies were conducted using different materials and application timings. Both studies evaluated the percent cover of newly seeded turfgrass. The first study employed 'Amazing GS' perennial ryegrass (Lolium perenne L.) the second was a patch mix material that consisted of 'Nexus" and 'Renaissance' perennial ryegrass, 'Clearwater' and 'Barron' Kentucky bluegrass (Poa pratensis L.), and 'Boreal' creeping red fescue (Festuca ruba ssp. littoralis). Both of these studies were conducted at the Valentine Turfgrass Research Center, Penn State University, University Park, Pa. The objective of these studies was to determine the control of the annual bluegrass (Poa annua L.) during the establishment of turfgrass. The studies were a randomized complete block design with three replications. Treatments of the first study were applied on June 29 (4 WBS), July 12 (2 WBS) , July 26 (SEED), August 24 (3 WAS), and September 6 (5 WAS), 2007 using a three foot CO2 powered boom sprayer calibrated to deliver 40 gpa using one, flat fan, 11004E nozzle at 40 psi. Treatments of the second study were applied on June 29 (4 WBS), July 12 (2 WBS), July 26 (SEED), August 9 (2 WAS), August 22 (4 WAS), and September 13 (6 WAS), 2007 using a shaker box. Glyphosate was applied to both test sites at a rate of 3 qts/A on June 6, 2007 prior to the application of test materials and was seeded July 26, 2007. Perennial ryegrass germination was first noted on the first study on September 1, 2007 and on September 2, 2007 for the sec ond study. Once established, the new turf was mowed once weekly at 2 inches with a rotary mower with clippings returned to the site. Perennial ryegrass cover, of the first study, was evaluated four times during the study. All treated turfgrass revealed some level of perennial ryegrass growth during the study. On the final rating date, September 19th, there was 90% or greater perennial ryegrass cover of treated or non treated turfgrass. Turfgrass cover, of the second study, was rated six times during the study. On the final rating date, October 5th, all treated and non treated turfgrass had at least 78% cover or greater. The percent cover of annual bluegrass, of the first study, was rated on September 25th. All Tenacity™ treated turfgrass had significantly less annual bl uegrass cover when compared to non treated turfgrass. The percent cover of annual bluegrass, of the second study, was rated on October 5th. Turfgrass treated with Lockup™ at 150 lb/A (penoxsulam 0.015 lb ai/A + 2,4-D at 1.5 lb ae/A) applied 4 WBS or 2 WBS, and 6 WAS had significantly less annual bluegrass cover when compared to non treated turfgrass." |
