| 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 'Phenom' perennial ryegrass (Lolium perenne, L.), multiple herbicide timings, and was conducted in 2007. The second study used similar herbicides applied only at the time of seeding with perennial ryegrass, 'Amazing GS'. Both of these studies were conducted at the Valentine Turfgrass Research Center, Pennsylvania 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 80 gpa using one, flat fan, 11008E nozzle at 40 psi. Treatments of the second study were applied at seeding on July 2, 2008 using the same application equipment. The sites had glyphosate at 6 qts/A applied prior to the application of test materials and was seeded July 26, 2007 and July 2, 2008. Perennial ryegrass germination was first noted on the first study on August 1, 2007 and on July 7, 2008 for the second study. Once established, the new turf was mowed once weekly at 2 inches with a rotary mower with clipping returned to the site for the first study. Once the second study was established, it was maintained at fairway height (0.500") and mowed three times weekly. Perennial ryegrass cover, of the first study, was evaluated four times. All treated turfgrass revealed some level of perennial ryegrass growth during the study. On the final rating date, September 19, 2007 there was 90% or greater perennial ryegrass cover of treated or non treated turfgrass. Turfgrass cover of the second study was rated on August 14, 2008. On the final rating date of the first study, October 5, 2007, 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 25, 2007. All mesotrione treated turfgrass had significantly less annual bluegrass cover when compared to non treated turfgrass. The percent cover of annual bluegrass, of the second study, was rated on October 15, 2008. In general, the single application of materials at the time of seeding did not reduce the annual bluegrass populations as dramatically as did the multiple applications of materials in the 2007 study." |
