This portal shares information about how ARS research is combating the disease that is devastating the citrus industry and provides information for the general public, as well as points of contact for those seeking more specialized answers.

Huanglongbing, also known as citrus greening, poses the most serious threat that the Florida citrus industry has ever faced. ARS scientists across the country are actively engaged in research with university and industry partners on all aspects of this disease problem, including the host, pathogen, and insect vector. Our goal is to overcome citrus greening and ensure the U.S. citrus industry can provide consumers with tasty, high quality citrus fruits for years to come.
