|a Lethal bronzing disease (LBD) is a lethal decline of various palm species caused by the 16SrIV-D phytoplasma. The disease was described in Texas in 2002 but found in Florida in 2006. Since its introduction, the phytoplasma has spread throughout much of the state. Typically, sampling of infected palms involves taking trunk tissue; however, in some instances this is not possible so alternative protocols are needed. In this study, phytoplasma titers were measured in different leaf tissues of infected palm in order to provide stakeholders with more sampling options. In addition, understanding the phytoplasma distribution in the palm canopy can shed light on the pathogen's biology and aid in vector studies. Three species of palm, Phoenix roebelinii, Sabal palmetto, and Syagrus romanzoffiana, were identified and confirmed positive for infection by qPCR analysis. Leaf tissue from these species that represented different stages of decay were sampled and tested by qPCR and dPCR. For each species, phytoplasma was only detectable in the spear leaf tissue that was connected directly to the apical meristem by both qPCR and dPCR. These data are useful by demonstrating that the 16SrIV-D phytoplasma appears to be restricted to the spear leaf so stakeholders who wish to sample palms but cannot sample trunk tissue due to palm size or lack of permission to drill into the trunk have an alternative tissue type to reliably sample. In addition, this information will help improve vector research by knowing where to collect insects that have a higher probably of possessing the phytoplasma
