| Abstract/Contents: | "Mefluidide (Embark) is a growth-regulating compound labeled for use on Kentucky bluegrass turf. Under some conditions, its use can result in turf discoloration. In this study, two fungicides propicanazole (Banner) and triadimefon (Bayleton), Ferromec (an iron source), and BA (benzyladenine, a synthetic cytokinin plant hormone) were applied in combination with mefluidide. The objectives of the study were to determine if the additives would reduce turf discoloration and to observe any effects the chemicals may have had on turf growth response to mefluidide. The study was conducted on a 5-year-old mixed stand of 'Parade', 'Glade', 'Rugby', and 'Adelphi' Kentucky bluegrass established on a Nicolett (fine-loamy, mixed-mesic, Aquic Hapludoll) soil with a pH of 6.9 and 2.3% organic matter. The turf was mowed at 2 in and had received 1 lb N/1000 ft2 before treatment. Treatments were applied on May 2 in three replications to 5 ft by 5 ft plots (Table 20). All of the treated plots were observed to have significantly lower turf quality than the control on May 16, June 1, and June 8 (Table 20). Ferromec AC provided an initial response over mefluidide alone at the first rating date, but no significant effects were observed after that time (Table 20). No significant response was observed on plots treated with propicanazole. BA and triadimefon did not significantly alter turf quality on any of the treated areas beyond those effects observed with mefluidide alone. All treated plots had significantly reduced leaf height from the control and all displayed greatly reduced seedhead formation. At the highest rate, propicanazole and triadmefon appeared to improve growth suppression over plots treated with mefluidide alone, although these variations were not significantly different at the 0.05 level. There were no differences in seedhead suppression among any of the treated plots. The spring and summer of 1990 were extremely wet. Through much of the test period, the plot area was saturated. In spite of the excessive moisture, mefluidide was effective in suppressing growth and seedhead formation. The effects of the additives may have been affected by the moisture, however, and further work should be conducted with these materials under more normal conditions." |
