The apple tree Malus domestica is subject to a wide range of diseases, which can be fungal, bacterial or viral; these diseases can seriously impair its growth and production. By weekly monitoring, we identified four major diseases that have established themselves in apple orchards on four varieties: Anna, Golden delicious, Red delicious and Dorset golden, in Tizi-Ouzouarea. These diseases are fungal disease: scab, powdery mildew, and canker; and of the bacterial order: fire blight.
