| USGA Summary Points: | Disease data from trials 1, 2, and 3 indicate that the onset and progress/severity of dollar spot during the subsequent growing season can be reduced by fungicide 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 in trials 1 and 2. Results in trial 3 suggested fluazinam was the key component in the suppression dollar spot in the fluazinam + propiconazole fungicide tank-mix. Cultivar susceptibility greatly influenced dollar spot onset and suppression. 007 and Coho delayed the disease onset date for approximately 1 and 3 weeks, respectively, compared to Independence. Quantification of pathogen DNA, using the qPCR method that we developed, indicated that the suppression of disease during 2022 was related to a lower pathogen inoculum load in the previous autumn. Trials to address objectives 2, 3, and 4 will be continued in 2023. |
