| Abstract/Contents: | "Demethylation inhibiting (DMI) fungicides may have phytotoxic effects on putting surfaces under periods of intense heat and stress. With newer DMIs chemistries available to turf managers, this study identified impacts of both long-established and recently-registered DMI formulations during the months of June and July on G12 ultradwarf bermudagrass (UDB) and July and August on Tyee creeping bentgrass (CB). A 6 x 2 factorial design was randomized within blocks across four replications at Independence Golf Club in Richmond, VA on UDB and at Glade Road Research Center in Blacksburg, VA on CB. Fungicides of interest included flutriafol, propiconazole, tebuconazole, mefentrifluconazole, and difenoconazole applied at the highest labeled rate. Each experiment consisted of 12 treatments where half of the treatments were watered in and half were not. Each experiment consisted of two fungicide applications made 14 days apart with data collected every 7 days after initial application for a total of 28 days. Weekly drone images were taken for digital image analysis, plots were assessed visually for turf quality and phytotoxicity, and clipping yields were collected to determine treatment effects. Preliminary results indicate that post-application irrigation had little effect on clipping yield at each location (p>.34). Overall, tebuconazole watered in resulted in the most phytotoxicity among treatments on UDB but phytotoxicity was similar for tebuconazole regardless of post-application irrigation. In creeping bentgrass, clipping yields varied by date with no differences between treatments that were watered in or not. No phytotoxicity was measured on creeping bentgrass throughout this study as well as variable differences in clipping yield by date and treatment." |
