USGA Summary Points:The initial preliminary trial indicates that the onset and progress of dollar spot during the subsequent growing season can be affected by fungicide chemistry applied during the previous autumn (September, October, and November). Tank mix applications of fluazinam + propiconazole in September and October had the greatest suppression of dollar spot during the subsequent growing season. The effectiveness of a November timing of fluazinam + propiconazole appeared dependent on environmental conditions at the time of application. This suggests that a weather-based approach may be needed to optimize the efficacy of late-season application(s) for the control of dollar spot during the subsequent growing season. Quantification of pathogen DNA indicated that the September fungicide timing was associated with a consistent reduction in the pathogen populations during the subsequent growing season. Additionally, fungicide chemistries applied in autumn had different effects on the subsequent pathogen populations. Trials to address objectives 2, 3, and 4 have been initiated and will be continued in 2022.
