    Abstract: Several olive nurseries in Jordan were surveyed for basal 
  and root rot fungi in olive cuttings during the rooting stage in Summer and 
  Autumn 2011. Causal agents were isolated from symptomatic olive cuttings on 
  PDA and identified according to specific keys. The most frequently isolated 
  fungi were <I>Pythium aphanidermatum </I>followed by <I>Fusarium solani</I>, 
  <I>Rhizoctonia solani </I>and <I>Verticllium dahlia</I>. Pathogenicity tests 
  showed variation in the disease incidence caused by the isolated fungi on olive 
  cuttings from different olive varieties. The highest disease incidence was caused 
  by the fungus <I>P. aphanidermatum</I> on raseei olive variety (47%) were on 
  other olive varieties, incidence ranged between 21 and 26%. The disease incidence 
  caused by each of the other isolated fungi ranged from 11-15% on the different 
  tested olive varieties. Var., raseei was the most affected by both <I>P. aphanidermatum 
  </I>(47%) and composite sample (68%). Analysis of variance showed significant 
  effects of nabali olive variety on disease incidence for the different fungal 
  isolates.
