| Abstract | ||||
| An integrated control program for peaches and apples powdery mildew was evaluatedboth Burg Al-Arab and South of Tahreer regions. In the first season, the efficiency of the program’s fungicides were tested in terms of the number of sprays and the most appropriate time to repeat the sprays, as well as the best effective fungicides. It was found that they all treatments were effective in controlling the disease. The best time to repeat spraying was from seven up to 10 days. In the second season, the chosen fungicides were evaluated compared with the farm fungicides individually, and the general control (sprayed with water only). On the other hand, evaluation of essential oils and fertilizers were done individually. The results showed the efficiency of systemic fungicide (Scor), copper and sulfur (preventive fungicides) and cinnamon oil and chitosan as Eco - friendly alternatives in controlling the disease. In the third season all tested fungicides used at the dormancy stage of trees at first January before buds swelling , data showed that all fungicides indicate high effect in decreasing the disease comparing with control at the in first of May compared to the control (100% disease severity). The tested fungicides gave 2.9% and 3.3% in case of peach at Borg Al-Arab and South of Tahreer respectively and 6%, 8.6% in apple at Borg Al-Arab and South of Tahreer respectively. At the fourth season all treatments combined in the integrated program were done at beginning spray (at 8 January while dormancy stage of trees) on apple. The tested program showed significant reduction on peach and apple powdery mildew compared to the control (100% disease severity) at the end of tested program comparing with the farm of tested program in case of peach and apple at Borg Al-Arab and South of Tahreer respectively, in May before harvest. In the fifth season the same tested program applied at t at the first of November during the winter tree service. The tested program was effective in control peach and apple powdery disease in locations. | ||||
