Abstract/Contents:"Fungicide applications targeting problematic soilborne diseases such as summer patch and fairy ring must be watered in for delivery to the target rootzone. Previous research indicates some residual control of the foliar disease dollar spot with some DMI fungicides despite immediately watering it in afterwards with 5 mm of post-application irrigation. This research builds upon the previous by assessing the impact of nineteen newer fungicide chemistries including those in the QoI and SDHI classes. Field studies were conducted at the University of Missouri Turfgrass Research Farm in 2021 and at the W.H. Daniel Turfgrass Center in 2023. Fungicides were applied in a split plot design with the whole plot treated with two watered-in applications separated by 28 days, with the first initiated when two-inch soil temperatures averaged 13Ā°C over five days. Later in the season, one half of the plot was treated with the same fungicide on a threshold-based schedule when five dollar spot infection centers were observed. In plots only receiving two watered in applications on 9 Apr and 7 May 2021, all fungicide treatments reduced dollar spot severity compared to the untreated control. Treatments of mefentrifluconazole, mefentrifluconazole + pyraclostrobin, benzovindiflupyr + difenoconazole, and triadimefon + trifloxystrobin had the lowest dollar spot severity with only two applications. Benzovindiflupyr + difenoconazole had the lowest brown patch severity with only two applications. On threshold-based plots, a fewer number of mefentrifluconazole, mefentrifluconazole + pyraclostrobin, and pydiflumetofen treatments were necessary than for most other treatments from 21 May through Oct 2021. Results of both trial years will be presented."
