Sampling Palms for Lethal Yellowing and Texas Phoenix Palm Decline Phytoplasmas

In Florida, palms are an economically important group of trees in the nursery and landscaping industries. Phytoplasma diseases of palms are a major concern because they infect a wide variety of these valuable ornamental palms, and they are lethal. Once symptoms appear, trees begin to decline, frequently rapidly, and can die in as few as 3 to 5 months. This 4-page fact sheet written by Brian W. Bahder and Ericka E. Helmick and published by the UF/IFAS Department of Entomology and Nematology describes how to sample palms for disease and how to submit samples to the Vector Entomology Lab. Includes a table listing equipment and supplies and protocol for sampling palm trunk tissue.
