| Abstract/Contents: | "This study was conducted on a mature stand of creeping bentgrass (Agrostis stolonifera) and annual bluegrass (Poa annua) at the Valentine Turfgrass Research Center, Penn State Univ., University Park, Pa. The objective of the study was to determine the efficacy of a fungicide, plant growth regulators alone or in combination with a liquid fertilizer using color ratings, dollar spot (Sclerotinia homeocarpa) incidence, measurements of plant height, and fresh weight foliar yield. This study was a randomized complete block design with three replications. Treatments were applied on June 8 (SUMMER), and July 12, 2005 (28 DAT) using a three foot CO2 powered boom sprayer calibrated to deliver 40 gpa using two, flat fan, 11004 nozzles at 40 psi. The test site was maintained similar to that of a golf course fairway wth respect to irrigation, fertilization and mowing. Turfgrass height was measured using a Turfcheck 1 prism. Turfgrass color was rated nine times during the study. None of the treated or untreated turfgrass was rated below acceptable (7.0) during the study. Turfgrass height was evaluated ten times during the study. On the June 22nd rating date turfgrass treated with Trimmit alone or in combination and Primo Maxx alone had significantly lower height than untreated turfgrass. On the June 29th rating date turfgrass treated with Trimmit alone, Primo MAXX at the 11 oz/A rate, and Trimmit at 32 oz/A plus ECO-N (24-0-0) had significantly lower height than untreated turfgrass. On the July 20th rating date turfgrass treated with Trimmit combined with Primo Maxx alone or with ECO-N (24-0-0) had significanlty lower height than untreated turfgrass. On the July 28th rating date turfgrass treated with Trimmit at 32 oz/A alone or combined with ECO-N (24-0-0) and Trimmit at 16 oz/A plus Primo MAXX plus ECO-N (24-0-0) had significantly lower height than untreated turfgrass. On the August 4th rating date turfgrass treated with Trimmit alone, Primo MAXX alone, Trimmit at 16 oz/A plus ECO-N (24-0-0), and Primo MAXX at 11 oz/A plus ECO-N (24-0-0) had significantly lower height than untreated turfgrass. On this date turfgrass treated with Banner MAXX had significantly higher height than untreated turfgrass. Finally, on the August 17th rating date turfgrass treated with Trimmit at 16 oz/A plus Primo MAXX plus ECO-N (24-0-0) had significantly higher height than untreated turfgrass. Turfgrass fresh clipping weights were collected six times during the study. On the June 22nd rating date only turfgrass treated with ECO-N (24-0-0) had significantly more fresh clipping weight than untreated turfgrass. On June the 29th rating date turfgrass treated with Trimmit at 32 oz/A and Trimmit at 16 oz/A plus Primo MAXX plus ECO-N (24-0-0) had significantly less fresh clipping weight than untreated turfgrass. On the July 12th rating date turfgrass treated with Trimmit at 32 oz/A plys ECON-N and Trimmit plus Primo MAXX had significanlty more fresh clipping weight than untreated turfgrass. Finally, on the August 17th date turfgrass rebound was apparent on some of the treated turfgrass. The percent dollar spot was rate five times during the study. On three ratings dates; July 14th, 20th, and August 4th turfgrass treated with Banner MAXX had significanlty less dollar spot than untreated turfgrass. On the July 14th and August 4th rating dates turfgrass treated with Trimmit at 16 oz/A plus Primo MAXX plus ECO-N (24-0-0) had significantly less dollar spot than untreated turfgrass. Finnaly on the August 4th rating date turfgrass treated with ECO-N (24-0-0) had significantly more dollar spot than untreated turfgrass." |
