Abstract

Efforts to identify the causal organism of apple stem canker were carried out. Samples were taken from 25 apple trees showing symptoms of stem canker at five different geographical locations of Daher Al jabal area in Sweida to isolate and identify the causal organism. Results showed that more than 90% of the isolates were Alternaria alternate (Fries) Keissler. This pathogen was able to induce canker symptoms on stems of 12 apple varieties under artificial inoculation conditions. Isolates from different geographical sites differed in their pathogenicity. Apple varieties tested showed also significant differences in their susceptibility to the disease. Wealthy double red and Starking delicious varieties were the least susceptible, while Golden lody was the most susceptible to Alternaria canker disease.
