Fusarium graminearum causes crown rot in wheat affecting seed germination, seedling establishment hence impacting crop productivity. Integrated disease management approaches includes cultural practices, use of good quality seed, resistant varieties, seed treatment. In this study, we surveyed wheat plant samples from South Dakota to determinethe prevalence and distribution of root rot pathogens. F. graminearum and Bipolaris sorokiniana were recovered from 100% and 48% of the root samples (n=39) collected, respectively. Further, we studied the effect of F. graminearum on the seed germination and seedling blight on spring wheat cultivars under greenhouse and field conditions. F. graminearum significantly affected the seed germination and seedling blight in 11 spring wheat cultivars, ranging from 75-96% and 0-9%, respectively in infested seed a.. View more»
