Fusarium wilt of Phoenix canariensis:first report in Greece

摘要

Canary Island palm (Phoenix canariensis)is used extensively as a landscape ornamental in Greece.In spring 2002 a severe disease was observed on these palms in Athens County.First symptoms began on the mature pinnae at the base of the plant,which became dry.Initially the leaflets on one side of the rachis died,but eventually the entire plant died.When the rachis was sectioned longitudinally,the vascular and adjacent tissue showed linear streaks of brown discoloration.The disease spread rapidly to neighbouring trees.When diseased trees were replaced with new healthy ones,these also became infected.
