The Effect Salicylic acid and Tashegazol fungicide in Protection of Cucumber Plant from Infection by Pythium aphanidermatum (Edson) Fitz in green house condition
ANBAR JOURNAL OF AGRICULTURAL SCIENCES,
2009, Volume 7, Issue 2, Pages 158-167
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.

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%.
