Field trials were conducted across nine different environments in Kentucky in 2017 and 2018 that evaluated a fungicide containing benzovindiflupyr + azoxystrobin + propiconazole applied to hybrid corn (Zea mays) at the six-leaf collar stage (V6) or at silking (R1) and a sequential application timing (V6 + R1). Results indicated that treatments that included an R1 application provided the best foliar disease control and were the only treatments that preserved yields compared with the nontreated control. A single application at R1 did not differ from the sequential V6 + R1 application for disease control or yield response, suggesting that Kentucky corn growers likely can rely on a more cost-effective single fungicide application at R1 for foliar disease management and improve return on fungicide investment rather than making multiple applications at different timings.
