Abstract
Field experiments in 2022 and 2024 evaluated fungicide applications and timing on foliar fungal diseases and Fusarium head blight (FHB) in the winter wheat cultivars Wesley (susceptible) and Zenda (moderately resistant). Metconazole + prothioconazole (Sphaerex) and picoxystrobin (Aproach) were applied once, twice, or three times during growth stages BBCH 31, BBCH 39, or BBCH 60. Disease levels were low in both years. Fusarium-damaged kernels (FDK) and deoxynivalenol (DON) were higher (p = 0.05) in Wesley than in Zenda. Applications at BBCH 39 and BBCH 60 reduced foliar disease severity. Due to low FHB levels, there were no differences among treatments in FHB index, FDK and DON. Yield did not differ among treatments in Zenda. In Wesley, yield in untreated plots was lower (p = 0.05) than in fungicide-treated plots. Applications in Zenda were unprofitable, with net returns ranging from ‒$469 ha‒1 to $92 ha‒1. In Wesley, net returns were positive in 93% of the treatments and ranged from ‒$269 ha‒1 to $329 ha‒1. Single applications were more profitable than multiple applications. These results suggest that a single fungicide application on a susceptible winter wheat cultivar at BBCH 39 or BBCH 60 can effectively and economically control foliar fungal diseases.
