| Abstract/Contents: | "A study to compare the efficacy of growth retarding compounds (amidochlor 4F, amidochlor 2G, S-1615 EPTC 10G, ACP-1900, ACP-1910, ACP-1920, ACP-1930, ACP-1940, mefluidide 2S) with respect to growth suppression, phytototxicity and seedhead suppression on tall fescue (Festuca arundinacea Schreb.) was initiated May 6, 1985. Treatments were applied to 0.9 by 6.1 meter plots arranged in a randomized complete block design with three replications. Amidochlor 2G and EPTC were applied with shaker bottles whereas S-1615 was applied with a 0.9 meter Scotts drop spreader. All other materials were applied with a hand-held boom sprayer. Grass heights and injury were periodically rated throughout the experiment. Seedhead suppression was also determined. Over the 77 day rating period all treatments suppressed tall fescue growth when compared to the check. The ACP-1900 series caused the most growth suppression followed by mefluidide. Amidochlor, EPTC and S-1615 displayed inferior growth inhibition over a 35 day rating period. ACP-1910, ACP-1920 and ACP-1930 caused undesirable injury for approximately 35 days after which the turf recovered (with the exception of that treated with ACP-1930). S-1615 had the best foliar appearance over the 49 days. Seedhead suppression 24 days after treatment was rated highest for ACP-1900, 1910, 1920, 1930 followed closely by ACP-1940 and mefluidide. All other compounds did not reduce seedheads to an acceptable level. At 77 days after treatment, the turf was rated for overall stand appearance, taking into account seedhead density and foliar appearance. ACP-1910, ACP-1920, ACP-1930, and ACP-1940 had a significantly better appearance than turf treated with mefluidide and ACP-1900. The check treatment along with amidochlor, EPTC and S-1615 treatments were all rated as unacceptable." |
