Macro-Sorb® Foliar (2.0 fl oz/1000 ft2 ) was applied every 2 weeks from May 8th to July 2nd, for a total of 5 applications. Disease severity was relatively low from May to July, but became extremely severe thereafter. Visual evaluations for Dollar Spot (%) were taken every 7 days for the duration of the study . Plots treated with Macro-Sorb® Foliar consistently had fewer dollar spot lesions, and during peak dollar spot outbreak (42 days after final application), Macro-Sorb® Foliar treated plots showed a 36% reduction in dollar spot compared to the untreated control.
