| Abstract/Contents: | "This study was conducted on a mixed stand of creeping bentgrass (Agrostis stolonifera) and annual bluegrass Poa annua at the Penn State Blue Golf Course in State College, PA. The objective of the study was to evaluate selected growth regulators, with and without additional adjuvants for the seedhead suppression of Poa annua under putting green conditions. Treatments were applied on April 12, 2002 using a three- oot C2 powered boom sprayer calibrated to deliver 40 GPA using two 6504 flat fan nozzles at 40 psi. The turf was maintained using cultural practices for irrigation, mowing, and fertilization that would be typical for a green. However, core cultivation was preformed on the study area on May 1, 2002 and mowing resumed on May 5, 2002. All treatments provided at least 70% seedheaded suppression on the May 10 rating date compared to the untreated control. Embark T/O at 40 oz/A with Ferromec at 5 oz/A and the combination of Proxy and Primo MAXX at 5 oz/ M and 0.125 oz/M respectively had significantly less seedhead suppression than Embark T/O at 40 oz/ A, Embark T/O at 40 oz/A with Ferromec at 5 oz/ M and Seedweed Cocktail at 0.25 gal/A, and Embark T/O at 40 oz/A with MacroSorb Foliar at 8 oz/M. On April 15, no treated turf was rated below 7 (an acceptable level). However, on April 18, turf treated with Embark T/O at 40 oz/A, Embark T/O at 40 oz/A with Ferromec at 5 oz/M and MacroSorb Foliar at 8 oz/M had color ratings slightly below acceptable (6.7). On April 26, turf treated with Proxy at 5 oz/M and Primo MAXX at 0.125 oz/M and Proxy at 5 oz/M with Primo MAXX at 0.125 oz/M plus MacroSorb Foliar at 4 and 8 oz/M had color comparable to the untreated check. It appeared the best treatments, considering seedhead suppression and color, were the Proxy at 5 oz/M and Primo MAXX at 0.125 oz/M plus MacroSorb Foliar at both 4 and 8 oz/M." |
