First report of verticillium wilt caused by Verticillium dahliae on Rudbeckia fulgida (orange coneflower) in Italy
Plant Disease 92 (9), 1367-1367
Abstract: During 2007, Rudbeckia fulgida (orange coneflower) plants grown in Italy were observed with symptoms of yellowing of external leaves and brown or black streaks in the vascular tissue of roots, crown, and leaves, resulting in wilting and stunting. The fungus Verticillium dahliae was isolated from the diseased plants. The identification was based on morphological characteristics and ITS sequence analysis. Pathogenicity of the isolates was demonstrated by inoculation.
