USGA Summary Points:All treatments suppressed Microdochium patch compared to the not-treated control with the exception of 0.1 lbs. of iron applied every two weeks as DTPA iron in the first two years and 0.2 lbs. of iron applied as DTPA in the second year of the study. In the first two years of the study, less than 1.5% Microdochium patch was observed when any rate of iron regardless of source was applied in combination with phosphorous acid compared to the non-treated control with greater than 40% disease. Turfgrass quality was only considered acceptable throughout the trial for the fungicide control treatment. High rates of iron sulfate or iron sulfate plus phosphorous acid provided disease control, although these treatments darkened plots and produced some turfgrass thinning.
