South Florida Palms and Lethal Bronzing

There's a new palm disease to be aware of called Lethal Bronzing that can potentially impact some of our most prestigious south Florida. Common symptoms include premature fruit drop (fruit is stunted, brown and or dead along with dead inflorescences), gradual browning of older leaves, then death of young/new fronds and eventually spear leaf death (center most frond growth point). While costly preventative measures are available unfortunately, there is no cure for infected palms and the only course of action once a palm is confirmed as infected is total removal. If you suspect a palm may have Lethal Bronzing please contact the local Broward County Cooperative Extension Service for additional advice and potential testing. Additional information about Lethal Bronzing can be found at the following IFAS website.
