Abstract
This study was conducted at Al-Hanadi forest nursery during the season 2017-2018 to identify the soil fungi causing the diseases of Evergreen Cypress seedling and determine the symptoms with estimating of their incidence and severity. Six fungal genera were isolated and purified from the bed soil and the roots of Evergreen Cypress. These genera namely, Fusarium, Aspergillus, Macrophomina, Verticillium, Cladosporium and Phoma. Fusarium was the most frequent in the soil compared to all other fungi and its incidence percentage was 28.5- 25% on the roots of the Evergreen Cypress seedling aged 4 and 12 months, respectively. The percentages of infection and severity were gradually increased with temperatures rising to reach the highest in June 10.1 & 4.6% for Evergreen Cypress seedling, respectively.
Keywords: Cupressus sempervirens, Soil fungi, Roots rot.
