| Abstract | ||||
| The dry rot disease incidence was affected by the different storage temperature degrees of both cultivations (Nili and Summer) during two tested seasons. The least periods of storage with least temperature degrees of storage (15 days at 3 – 5°C) decreased dry rot disease incidence % in both lasted seasons. Significant differences were notice between periods of storage which combined with different temperature degrees. Eight plant extracts were tested against dry rot disease in potato tubers. Three concentrations of each plant extract were used i.e. 3, 5 and 10%. Garlic and cinnamon extracts were tested against the most aggressive fungal isolates, under storage conditions on potato tubers cv. Spunta. Both plant extracts were effective on disease index and minimized potato dry rot disease symptoms. Biological control using biological agents were effective in disease control both in laboratory and under storage conditions. Also, Tachigaren plus 600 SL fungicide at 100 ppm was the most effective one in controlling the dry rot disease incidence. | ||||
