Fusarium oxysporum f. sp. canariensis causes Fusarium wilt disease on the Canary Island date palm (Phoenix canariensis). To facilitate disease management, a polymerase chain reaction diagnostic method has been developed to rapidly detect the pathogen. A partial genomic library of F. oxysporum f. sp. canariensis isolate 95-913 was used to identify a DNA sequence diagnostic for a lineage containing all tested isolates of F. oxysporum f. sp. canariensis. Two oligonucleotide primers were designed and used to amplify a 567-bp fragment with F. oxysporum f. sp. canariensis DNAs. DNA from 61 outgroup isolates did not amplify using these primers. Once the primers were shown to amplify a 0.567-kb fragment from DNA of all the F. oxysporum f. sp. canariensis isolates tested, a rapid DNA extraction procedure was developed that led to the correct identification of 98% of the tested F. oxysporum f. sp. canariensis isolates.

Since the mid-1990s, several new pathogens and diseases have emerged on palms (Arecaceae) growing in Florida. These include two formae speciales of Fusarium oxysporum, with f. sp. canariensis causing fusarium wilt of canary island date palm (Phoenix canariensis) and a new forma specialis causing Fusarium wilt of queen palm (Syagrus romanzoffiana) and mexican fan palm (Washingtonia robusta). The texas phoenix palm decline phytoplasma (‘Candidatus Phytoplasma palmae’ subgroup 16SrIV-D), which causes a lethal yellowing-type disease, has been detected in date palms (Phoenix spp.), queen palm, and cabbage palm (Sabal palmetto). New rachis (petiole) blight pathogens include Cocoicola californica on mexican fan palm and Serenomyces species on several palm species.

Unlike most fungal diseases of palms, this disease is very host specific, with the primary host being Phoenix canariensis (Canary Island date palm). It is caused by Fusarium oxysporum f. sp. canariensis. The name “Fusarium wilt of Canary Island date palm” was given to this disease to distinguish it from two other Fusarium wilt diseases that occur on palms, which are also very host specific. In Florida (and the U.S.), the name is often shortened to simply “Fusarium wilt.” This document is PP-215, one of a series of the Plant Pathology Department, UF/IFAS Extension.

Abstract With the increasing expansion in urban areas, many species have adapted to utilising horticulturally used plants as alternate or augmentary food sources, in particular, during winter – when native foods are largely absent. Ornamental palms, particularly Canary Island Date Palms, fruit continuously during most of the year and thus provide a stable food supply. Based on observational, metric and bio-chemical data, this paper examines the role Canary Island Date Palms can and do play in the nutrition of frugivorous animals, in particular, for birds. It demonstrates that with its nearly year-round provisioning of drupes, the palm plays a major role as a ‘staple’ and backup food source for several species.

Lethal bronzing (LB), also previously known as date palm lethal decline or Texas Phoenix palm decline, associated with phytoplasma subgroup 16SrIV-D, was first identified in Louisiana in December 2013. A survey of palms showed that the disease was not only confined to City Park in New Orleans, where it was first detected, but is present in other parts of Orleans Parish, as well as two adjacent parishes. Canary Island date palms (Phoenix canariensis) tested positive at the highest frequency, and some edible date palms (P. dactylifera) and a small proportion of cabbage palms (Sabal palmetto) tested positive as well. Symptoms do not appear to be a reliable indicator of LB, because a substantial proportion of palms indicated as symptomatic tested negative. Furthermore, not all infected palms showed symptoms. Since the palm survey conducted in 2015 to 2016, LB has positively been identified from silver date palm (P. sylvestris) and Chinese windmill palm (Trachycarpus fortunei) in three additional parishes in Louisiana.

Vascular Discoloration

Canary Island date palm (Phoenix canariensis Hort. Ex Chabaud) is a signature palm planted in New Orleans, LA. Currently, the city has approximately 1,000 mature Canary Island date palms. During the fall of 2009, 153 palms were inspected with 27 palms exhibiting typical symptoms of Fusarium wilt. Symptoms included one-sided death and a reddish brown streak on the rachis of affected fronds and death of the leaflets. Longitudinal sections of affected fronds showed vascular discoloration. Severely infected palms were completely dead. Small pieces of diseased tissue from five palms were surface sterilized with sodium hypochlorite (0.6%) for 2 to 3 min, then rinsed in sterile distilled water, blotted dry, and plated on potato dextrose agar (PDA). Fungal colonies on PDA produced a purple pigment, and both macro- and microconidia that are typical of Fusarium oxysporum were observed under a light microscope. A single-spore culture of isolate PDC-4701 was obtained. DNA from this isolate was extracted with a DNeasy Plant Mini kit (Qiagen Inc., Valencia, CA) and primers ef1 and ef2 were used to amplify and sequence the translation elongation factor 1-α gene (2). NCBI BLAST analysis of the 616-bp sequence resulted in 100% identity with F. oxysporum f. sp. canariensis isolates PLM-385B from Texas and PLM-511A from South Carolina (GenBank Accession Nos. HM 591538 and HM 591537, respectively). Isolate PDC-4701, grown on PDA for 2 weeks, was used to inoculate 10 9-month-old P. canariensis seedlings. An 18-gauge needle was used to inject 15 ml of a 107 conidia/ml suspension into the stem near the soil line. Each seedling was inoculated at two locations and covered with Parafilm at the inoculation sites. Ten control seedlings were injected with sterile distilled water in the same manner. Inoculated and control seedlings were maintained in a greenhouse at 28 ± 2°C. Leaves of all 10 inoculated seedlings started to wilt 3 months after inoculation. Internal vascular discoloration was observed and the pathogen was reisolated from the symptomatic seedlings. No symptoms developed on any of the 10 control seedlings. On the basis of morphology and DNA sequence data, this pathogen is identified as F. oxysporum f. sp. canariensis. Fusarium wilt of Canary Island date palm has been previously reported from California, Florida, Nevada, Texas, and South Carolina (1). To our knowledge, this is the first report of Fusarium wilt of Canary Island date palm caused by F. oxysporum f. sp. canariensis in Louisiana, extending its geographic range. The disease may adversely affect the tradition of planting Canary Island date palms in New Orleans. The sequence of isolate PDC-4701 has been submitted to the NCBI database (GenBank Accession No. JF826442) and a culture specimen has been deposited in the Fusarium Research Center culture collection (Accession No. O-2602) at the Pennsylvania State University, University Park, PA.

Shaped Pattern

The Canary Island date palm is native to the Canary Islands. Although it can reach heights of 40–50 feet, it is slow growing and requires many years to attain that height. It has 8- to 15-foot-long rigid leaves that contain up to 200 V-shaped leaflets, the basal ones of which are modified into long, sharp spines. Leaves are not self-cleaning and must be manually removed when dead, but the leaf bases eventually rot off, leaving an attractive diamond-shaped pattern of leaf scars on the 2- to 3-foot-diameter trunk. On older specimens, the basal foot or so of the trunk typically is covered with short root initials. This 6-page fact sheet was written by T. K. Broschat, and published by the UF Department of Environmental Horticulture, August 2013. http://edis.ifas.ufl.edu/st439

During the summer of 2004, severe symptoms of wilt were observed on 25-year-old plants of Canary Island Date Palm (Phoenix canariensis Hort. ex Chabaud) located at the seafront of Poetto Beach in the metropolitan area of Cagliari, southern Sardinia, Italy. Symptoms consisted of one-sided leaflet dieback of fronds, necrotic and brown streaking on the lower rachis base of older leaves, and necrosis of vascular bundles. Of 300 palms, there were 90 plants that were symptomatic and at least 4 were dead. Fusarium oxysporum Schlecht. emend. Snyder & Hansen has been consistently isolated from surface-sterilized petioles of symptomatic leaves sampled from affected palms. The opportunistic pathogen Gliocladium vermoesenii (Biourge) Thom was frequently associated with F. oxysporum in diseased samples, confirming previous reports of a disease complex between these two fungi (1). Five F. oxysporum isolates collected from different symptomatic plants were analyzed with a polymerase chain reaction (PCR)-based assay with the F. oxysporum f. sp. canariensis-specific primers HK66 + HK67 (2). The thermocycling schedule was as follows: initial denaturation at 94°C for 5 min, 35 cycles each of 1 min at 94°C, 1 min at 62°C, 1 min and 30 s at 72°C, followed by a final extension at 72°C for 5 min. A 567-bp PCR product of the expected size was obtained from all tested F. oxysporum isolates, allowing their identification as F. oxysporum f. sp. canariensis. This disease was previously reported from other Italian regions (Sicily, Marche, and Liguria), but its presence in Sardinia should be considered carefully since it represents a serious threat to ornamental palms, which are abundant all over the island. The source of this outbreak may be related to the importation of seedlings from areas where F. oxysporum f. sp. canariensis is widely established. References: (1) H. D. Ohr.
