Description
Results from wilt pathogenicity and race evaluations for 25 North Dakota Fusarium oxysporum f.sp. pisi (Fop) isolates conducted in the greenhouse indicated all Fop races exist in North Dakota. Race 2 isolates were more frequently recovered from plants with root rot symptoms. Root rot assays also conducted in the greenhouse demonstrated that most Fop isolates were as aggressive as F. solani and F. avenaceum based on increased root disease severity. Results from field experiments conducted in 4 sites in the MonDak region between 2017 and 2019 evaluating the effect of three planting dates and six durum varieties with differing levels of susceptibility to leaf spot and Fusarium Head Blight (FHB) indicated that early planting maximized yield and influenced ergot incidence. Although planting date did not affect late leaf spot and DON, choosing less susceptible varieties to fungal leaf spot and FHB reduced late fungal leaf spot and DON, respectively.
