- Abstract
-
This study aimed to identify the cause of apple scab disease, which affects apple trees in the Al-Jabal Al-Akhdar region – Libya, and was conducted during the 2018-2019 season. Several samples were collected from the apple variety (Red delicious), and the causal organism was isolated and purified. The results of the study of the general morphological and cultural characteristics of the pathogen proved that the cause of the disease is the fungus Venturia inaequalis, which produced typical symptoms of apple scab on leaves and seedlings of the same variety.
