Unknown disease killing off Florida’s state tree (AP) Posted on July 24th
This is a phytoplasma disease, which means it is a very small bacterium that doesn’t have a cell wall. And it can only be transmitted through a plant’s phloem, a type of transport tissue similar to veins in a human. The disease has likely found its way to sabal palms’ phloem by either a tree- or leaf-hopping insect.
