USGA Summary Points:At the peak of disease in both years of the study, there was no Microdochium patch present on treatments that were applied every 2 weeks (treatments 1 through 6) although some of these treatments did have disease earlier in the study but had recuperated as the trial progressed (Table 1). Treatments 1 through 6 were significantly different from the control in both years of the study at the peak of disease (Table 1). All treatments applied using a three-week frequency had some disease present in at least one of the two years at the peak of disease. Regarding turfgrass quality, the only treatments that were significantly different from the control occurred among application frequencies of every two weeks (Figures 1 and 2). In both years of the trial, analysis of the percent disease data at the peak of disease, Jan 28, 2017 and Feb 26, 2018 respectively, showed that when phosphorous acid was applied, there was no significant benefit to the suppression of Microdochium patch by combining phosphorous acid with iron sulfate. In contrast to the first bullet point, phosphorous acid added to lower rates of iron sulfate did improve Microdochium patch suppression compared to iron sulfate applications alone (Figures 3 and 4). Regarding turfgrass quality at the peak of disease, no treatments received an acceptable turfgrass rating because of either the presence of disease or turfgrass thinning caused by the highest rates of iron sulfate (Figure 5 and 6).
