This fact sheet is limited to those diseases where the pathogens only infect (invade) and cause spots and blights of the leaf blade. Other diseases may cause death of leaflets and leaf segments but are actually the result of a pathogen infecting the leaf petiole or rachis. Petiole/rachis blight diseases are discussed separately at http://edis.ifas.ufl.edu/pp145. This document is PP-218, one of a series of the Plant Pathology Department, UF/IFAS Extension.

Leaf Spots

The fungus Pestalotiopsis causes leaf spots, petiole/rachis blights and sometimes a bud rot of palms. In other words, unlike the other leaf spot and petiole blight pathogens, which attack either the leaf blade or the leaf petiole, Pestalotiopsis attacks all parts of the leaf from base to tip. It is also one of the more ubiquitous fungi in the palm canopy, and is easily isolated from healthy palm tissue. This document is PP-217, one of a series of the Plant Pathology Department, UF/IFAS Extension. Original publication date January 2006.  PP-217/PP141: Pestalotiopsis (Pestalotia) Diseases of Palm (ufl.edu)

In general, the “typical” or “classic” petiole blight is a disease in which the pathogen only infects the petiole. The disease symptoms may look like the pathogen has also infected the leaf blade, but this is a secondary affect from petiole infection. An exception to the “typical” petiole blight is a disease caused by Pestalotiopsis. This pathogen causes both a leaf spot and blight as well as a petiole or rachis blight, usually at the same time. It is discussed in a separate fact sheet (PP141). This document is PP-221, one of a series of the Plant Pathology Department, UF/IFAS Extension. Original publication date January 2006.

There are many pathogens that can cause bud rots of palm in Florida. The most common one is Phytophthora palmivora, followed by Thielaviopsis paradoxa and bacteria. Symptoms of bud rot are similar no matter which pathogen causes the disease. This document is PP-220, one of a series of the Plant Pathology Department, UF/IFAS Extension.

Lethal yellowing (LY) is a palm disease prevalent in Florida landscapes in the southern one-third of the state. It is also observed in field nurseries. This disease has significantly reduced the number of tall-type Cocos nucifera (coconut) in Florida and the Caribbean Basin, and localized outbreaks continue to occur. This document is PP-222, one of a series of the Plant Pathology Department, UF/IFAS Extension. Original publication date January 2006. PP-222/PP146: Lethal Yellowing (LY) of Palm (ufl.edu)

Thielaviopsis paradoxa is a fungus that can infect any part of a palm, and so can cause numerous diseases. In Florida, the two most frequent (and usually lethal) Thielaviopsis diseases observed in the landscape and field nursery are a bud (heart) rot and trunk rot. Thielaviopsis bud rot is discussed at http://edis.ifas.ufl.edu/pp144. This document is PP-219, one of a series of the Plant Pathology Department, UF/IFAS Extension.
