USGA Summary Points: | Dollar spot forecasting by a logistic regression model had good accuracy for highly susceptible cultivars during 2015, early-2016, and 2017. Moderate 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 four to five fungicide applications during 2015 and 2017, respectively, depending on the initial fungicide timing. In contrast, threshold-based fungicide applications on Independence creeping bentgrass produced moderate disease control and resulted in a total of six or seven applications during 2015 and six to nine applications during 2017, depending on the initial fungicide timing. |
