A Technical Report from The Bartlett Tree Research Laboratories
Date palm wilt, caused by the fungus Fusarium oxysporum f. sp. canariensis, is the most serious and lethal disease of Canary Island date palm (Phoenix canariensis). This disease leads to dieback of individual fronds, usually beginning in the lower canopy, and eventually results in plant mortality. There is no chemical treatment that has proven effective against this disease. It is important to remember in all phases of plant care that this is a highly infectious and lethal disease and care must be taken to prevent spread.
