USGA Summary Points:Dollar spot forecasting by a logistic regression model had good accuracy for highly susceptible cultivars during 2015, but over-predicted during 2016. Good to excellent, season-long disease control was achieved when subsequent fungicide timing was based on a threshold program, but total fungicide inputs and the level of disease control depended on the cultivar and, to a lesser extent, the initial fungicide timing. Fungicide applications on 'Declaration' creeping bentgrass that were threshold-based produced excellent disease control and resulted in only three and one fungicide applications during 2015 and 2016, respectively, regardless of the initial fungicide application date. In contrast, threshold-based fungicide applications on 'Independence' creeping bentgrass resulted in a total of six or seven applications during 2015 and four or five applications during 2016, depending on the initial fungicide timing.
