dc.description A potato wilt survey conducted in two parts was performed during the 1977 growing season in five counties of North Dakota. Results indicate Fusarium spp. is the major wilt pathogen of potatoes. Verticillium spp. and Erwinia carotovora var. atroseptica (blackleg organism) were also found in high percentages in wilted plants. Colletotrichum and Rhizoctonia were isolated in nearly equal proportions. A high percent of wilted plants were found to contain more than one wilt-causing organism which indicated that mixed infection occurred. The interaction of wilt organisms in multiple infections increases the complexity of the potato wilt disease and makes control much more difficult. en
