The most important disease of wild-rice in Minnesota is Helminthosporium headblight caused by Drechslera oryzae and D sorokiniana. Grain yield of wild-rice inoculated with a water suspension of 100 000 spores of Drechslera spp./ml was increased by application of 1.68 kg of Dithane M-45 [mancozeb]/ha and tended to be increased by 0.56 kg BAY 78418 [edifenphos] or 2.25 kg copper hydroxide/ha, compared with the control given no fungicide. ADDITIONAL ABSTRACT: The following diseases of Zizania aquatica are described: blight (Drechslera oryzae [Cochliobolus miyabeanus] and D. sorokiniana [C. sativus], stem rot (Helminthosporium sigmoideum [Magnaporthe salvinii] and Sclerotium spp.), bacterial streak (Xanthomonas translucens), ergot (Claviceps zizaniae) and stem and leaf smut (Entyloma lineatum).
