| Abstract: | Acacia koa seedlings were evaluated from plantings and commercial nurseries for colonization by Fusarium spp., particularly F. oxysporum, the putative cause of koa wilt/dieback disease in Hawaii. We sampled 162 seedlings, 90% of which were from nurseries on the islands of Hawaii, Maui, Kauai, and Oahu. Fusarium oxysporum was detected on about 78% of sampled seedlings. It was most prevalent on roots; more than 50% of all sampled root pieces were colonized by this species. Ten additional Fusarium species were isolated from seedlings, but all colonized plant tissues at much lower levels. More than 70% of all samples from seedlings yielded Fusarium spp. The potential importance of this high level of colonization is discussed. |
