Texas Phoenix palm decline is a new disease in Florida, caused by an unculturable bacterium. It is a fatal, systemic disease that kills palms relatively quickly. This six-page fact sheet explains the pathogen and hosts of TPPD, its symptoms, how to diagnose it, and provides disease management practices. Written by Nigel A. Harrison and Monica L. Elliott and published by the Plant Pathology Department.

Calonectria (Cylindrocladium) Leaf Spot of Palm (PP302)
Calonectria is a fungus that affects a large number of hosts worldwide, including timber and ornamental, agricultural, and horticultural crops, causing a wide range of disease symptoms, such as cutting rot, damping-off of seedlings, leaf spot, shoot blight, and root rot. This 4-page fact sheet was written by Jiaming Yu and Monica L. Elliott, and published by the UF Department of Plant Pathology, January 2013.

Hurricane-Damaged Palms in the Landscape: Care after the Storm (ENH1204/EP465)
While many palm species are adapted to windstorms, a hurricane can damage even the most tolerant palms. This 3-page fact sheet provides suggestions about what to do after a windstorm has occurred once it is safe to venture outside to care for the landscape.

Fusarium Wilt of Canary Island Date Palm (PP215/PP139)
As the name implies, Fusarium wilt of Canary Island date palm is primarily observed on the Canary Island date palm. It was first documented in the United States in the 1970s in California, but it was not documented in Florida until 1994. It now occurs throughout the state. The fungus obstructs the xylem (water-conducting) tissue, which results in desiccation and death. This 5-page fact sheet was written by Monica L. Elliott, and published by the UF Department of Plant Pathology, July 2012.

Bud Rot of Palm (PP220/PP144)
To understand bud rots, an explanation of palm anatomy is necessary. The growing point of the palm is often called the bud or heart. All leaves originate from there, and each palm stem has only one. Thus, when the bud is damaged or diseased, the palm usually dies. The first symptom is discoloration and wilting of the spear leaf and wilting/discoloration of the next youngest leaf. This 4-page fact sheet was written by Monica L. Elliott, and published by the UF Department of Plant Pathology, July 2012.

Brown Patch (SSPLP5/LH044)
Brown patch, large patch, or Rhizoctonia blight is a fungal disease observed November through May that infects the leaf area closest to the soil, eventually killing the leaf.

Take-all Root Rot (SSPLP16/LH079)
Take-all root rot, or Bermudagrass decline, is a root rot disease triggered by high rainfall or stress and manifesting as irregular yellow or light green patches two to three weekds after the pathogen has been active in the roots. This 3-page fact sheet was written by M. L. Elliott and P. F. Harmon and published by the UF Department of Plant Pathology, February 2011.

Turfgrass Disease Management (SSPLP14/LH040)
Turfgrass diseases are underappreciated because the biological organisms (plant pathogens) causing the problems are rarely observed. Fortunately, grasses maintained using proper cultural practices (water, mowing, and fertility) are not as likely to become diseased or be as severely damaged as grasses that do not receive proper care. This 11-page fact sheet discusses turfgrass diseases, their causal agents, diagnosis, and management. Written by M. L. Elliott and P. F. Harmon and published by the UF Department of Plant Pathology, February 2011.
