Abstract
Wilted pomegranate trees (2793 trees) were surveyed for microorganisms associated with their roots and soil. Samples were collected from fifteen sites in Sadah governorate. Data demonstrated that pomegranate wilt disease symptoms were 17.3%. Fungi isolation frequency from soil and disease roots recorded 37.8 % and 59% for Fusarium oxysporum, respectively. Four genera of plant parasitic nematodes namely, Tylenchus sp., Tylenchorhynchus sp., Helicotylenchus sp. and Longidorus sp. were also isolated with frequency rate and densities 9, 5, 3, 1 % and 428, 340, 187, 200 nematodes/kg soil respectively.
