| Abstract/Contents: | "Dollar spot is a devastating and ubiquitous pathogen of turf in much of the world, necessitating frequent fungicide application for effective control. As such, fungicide stewardship through integrated pest management can reduce the risk of fungicide resistance, minimize environmental impact of fungicide application, and reduce total cost spent on fungicides. In this study we integrate differing levels of nitrogen fertility, a cultural practice associated with dollar spot disease reduction, and the highly efficacious fungicides fluazinam and fluxapyroxad for the control of dollar spot. Fungicide application timing was tested comparing a 21-day calendar application to Smith-Kerns disease decision support model thresholds targeting 20%, 30%, and 40% disease risk percentage. Resulting disease for the interaction of these variables along with total number of fungicide applications are compared to optimize best-practice disease control strategies within these parameters. This work has the potential to narrow action thresholds for turf professionals in the Connecticut area while providing integrative tools to reduce the total number of fungicide applications necessary for dollar spot control." |
