| Abstract | ||
| Stem canker and black scurf caused by Rhizoctonia solani Kuhn is considered the most destructive disease and reduce productivity of potato. Pathogenicity test of 12 isolates of R. solani obtained from two governorates, El- Sharkiya (New El–Salhia region) and Ismailia (El-Shabab region) revealed that all isolates were pathogenic, however isolate No.RS7 was the most virulent isolate in the development of the stem canker and black scurf disease. Molecular technique using PCR applied to determine anastomosis group of isolate No. RS7 showed that this isolate belong to AG3. | ||
