| Abstract/Contents: | "Dollar spot, caused by Clarireedia jacksonii, is a prominent and chronic disease of many turfgrasses. Managing dollar spot on intensively cultivated turfgrass relies on the judicious use of fungicides. Repeated applications, however, have resulted in reduced efficacy due to resistance. The objective of this study was to identify the range of disease control among commercially available DMI fungicides on a resistant C. jacksonii population. In 2022, a field trial was established at Mountain View Country Club, located in Boalsburg, PA. The creeping bentgrass (Agrostis stolonifera L.) and annual bluegrass (Poa annua L.) fairway had previously been shown to have reduced sensitivity to DMI fungicides. Treatments included low and high rates of 9 commercially available DMI fungicides applied at 14 or 21-day intervals, respectively. The study was arranged as a randomized complete block design with 4 replications. Plots measured 0.9 x 1.8 m and treatments were applied through a CO2 pressurized sprayer calibrated to deliver 409 L H20/ha. Treatments were applied from 25 May to 7 September and dollar spot was rated by counting the number of infection centers per plot. Dollar spot pressure peaked on 12 September. On this rating date, dollar spot infection centers ranged from 116 to 311 per plot, and differences among fungicides were observed. Based on this field trial, active ingredients within the DMI chemical class 1) may have inherent differences in their suppression of dollar spot or 2) may not be cross resistant to insensitive populations of C. jacksonii. Isolates were obtained from all plots and in vitro cross-resistance screening across DMI fungicides is currently being evaluated." |
