False Smut

Graphiola leaf spot, also referred to as “false smut,” is a foliar pathogen of certain palm species. In Florida, it is primarily a cosmetic disease and does not adversely affect plant growth. Nutrient deficiencies, such as potassium or magnesium deficiency, are much more serious palm health problems than this disease, especially for Phoenix palm species. This document is PP-216, one of a series of the Plant Pathology Department, UF/IFAS Extension. Original publication date January 2006.

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.

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.

Pythium blight or cottony blight rapidly kills cool-season turfgrasses overseeded as winter cover of warm-season species. The disease can occur on bermudagrass in the summer, but disease severity on this warm-season species often is limited when compared to the damage caused to cool-season turfgrass. Pythium aphanidermatum as well as other species, such as P. torulosum, have been associated with Pythium blight of overseeded turfgrasses in Florida. This document is PP 203, one of a series of the Plant Pathology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. Original publication date September 2004.  PP 203/PP124: Pythium Blight on Overseeded Turfgrass (ufl.edu)
