dc.description.abstractLate leaf spot (LLS), caused by Nothopassalora personata, and Sclerotinia blight (SB), caused by Sclerotinia minor, are significant diseases affecting peanut production in Virginia. Field trials were conducted in 2020 - 2022 at two locations per year to identify fungicide programs that manage both diseases. In 2020, pydiflumetofen applied independently, as well as in combination with a premix of azoxystrobin + benzovindiflupyr, provided effective protection against both LLS and SB. This combination demonstrated potential as a cost-effective alternative to fluazinam. Years 2021 and 2022 focused on the most effective timing of pydiflumetofen and the premix of azoxystrobin + benzovindiflupyr. Results demonstrated that the combination of pydiflumetofen and the premix of azoxystrobin + benzovindiflupyr applied 60 and 90 days after planting was most consistent in providing the greatest efficacy against both diseases while improving yield. The tank-mix/premix combination of pydiflumetofen and azoxystrobin + benzovindiflupyr offers effective and economical management of both LLS and SB compared to fungicide programs where fluazinam is added for SB management only.en
