The Effect Salicylic acid and Tashegazol fungicide in Protection of Cucumber Plant from Infection by Pythium aphanidermatum (Edson) Fitz in green house condition
AbstractThe salicylic acid and Tashegazol fungicide had a high level of inactivation of fungal growth of P. aphanidermatum which reached to 100% when they added to potato sucrose agar (PSA) at 400 mg/L rate. Under green house condition the salicylic acid and tashegazol fungicide reduced the infection percent (pre-damping off) to 13.33, 23.33, 53.33 % respectively, the post damping off percent reduced to 6.66, 10.00, 20.00% respectively. البحث مستل من أطروحة دكتوراه للباحث الأول The percent of wilt infection was reduced from 16.66%to control treatment to 3.33% to the salicylic acid treatment, the lowest disease severity achieved by salicylic acid treatment 52.06% then tashegazol 74.98% compared to control treatment which was 88.41% in addition all the dry weight of shoot, roots and plants heights increased significantly by salicylic acid treatment, content of cucumber leaf from total protein increased to 25.93% compared to control treatment 15.25%.
