Abstract
During 2010, soybean (Glycine max Cl. Merr.), exhibited symptoms of web blight on the leaves of the grown plants (Fig. 1) in fields at Upper Egypt (Assiut Governorate). Seven isolates of Rhizoctonia solani were isolated from the leaves and leaf petioles of diseased soybean plants and tested for their pathogenicity on cv. Giza 22 by artificial inoculation. Results revealed that only two isolates caused web blight. These isolates were identified, according to their morphological and cultural characteristics, as R. solani AG-1 (IA). This is the first record of Rhizoctonia web blight disease on soybean in Egypt.
