Abstract: | A Fusarium oxysporum sensu Snyder & Hansen was pathogenic in the vascular tissue and caused a severe wilt and dieback of ×Fatshedera lizei, Fatsia japonica and Hedera helix. The fungus appeared nonpathogenic on plants of 29 species in numerous genera. Benomyl soil drenches were effective in preventing infection. A new forma specialis, Fusarium oxysporum f. sp. fatshederae, f. sp. nov. is proposed for this pathogen. |
