Lethal Bronzing, previously called Texas Phoenix Palm Decline, is a relatively new bacterial disease that is causing significant palm losses in Palm Beach County and may be working its way south.

University of Florida research is determining which sap-feeding insect(s) may spread it this disease. Affected species include Sabal (Cabbage), Queen, Pygmy Date, and other Phoenix species, Christmas, Bismarck, Chinese Fan, and Carpentaria palms.

Older fronds on palms die first turning reddish-brown, dark-brown or grayish depending on the Palm species and stage of infection. Symptoms may be confused with a simple nutrient deficiency which is why it’s important to work with a team that is trained to recognize the difference. Flower spikes may die prematurely, and fruit may drop off prematurely.
