USGA Summary Points: | The AT + RH model provided control of dollar spot, which was comparable to the calendar-based treatments while providing an average reduction of one-fungicide application. The RH only model averaged a fourspray reduction versus the calendar based applications with improved control over not-treating for dollar spot; however, it consistently under-predicted dollar spot epidemics, which resulted in high levels of disease compared to the calendar-based treatment in two locations. The AT + RH model tended to overpredict fungicide applications by one spray vs. the RH only model which tended to under-predict fungicide application by at least two sprays. To improve the accuracy of the models, 2012 research will focus on tailoring action thresholds and also specific models to each "zone" of the U.S. where the models are tested. |
