The incidence of Bipolaris oryzae and B. sorokiniana in cultivated wild rice seed collected from two fields in Minnesota during 1991 and 1992 was related to disease severity on leaves. The site of Bipolaris spp. on the seed was primarily the awns. Caryopses were not infected under the conditions of this study. This is the first evidence for B. oryzae and B. sorokiniana being seedborne on cultivated wild rice and located primarily in the external tissues of the seed.
