NPDN Governance Committee Report NPDN Regional Network Meeting Notes |
NPDN National Meeting 2007 Poster Abstract Authors: CARRIE L. HARMON (1), Tim S. Schubert (2), Anne Vitoreli (3) Affiliations: (1) Department of Plant Pathology, UF, Gainesville, FL, USA; (2) Division of Plant Industry, Florida Dept. of Ag. and Consumer Services., Gainesville, FL, USA; (3) Plant Disease Clinic, University of Florida, Gainesville, FL, USA The National Plant Diagnostic Network (NPDN) has been involved in detection and diagnosis of many new plant diseases, including preparation for the exotic disease known as citrus variegated chlorosis (CVC), caused by a particular strain of the xylem-limited sharpshooter-transmitted bacterium, Xylella fastidiosa. Most citrus cultivars grown in the US are susceptible to the disease, increasing its potential impact on citrus production both in commercial and residential settings. While presently impossible to diagnose in the field, the pathogen can be detected in the lab by light microscopy and culture on selective media. Serological and molecular methods of detection are also available, but like the microscopic and cultural methods, do not always reliably distinguish between CVC and other Xylella diseases already in the US. Disease management methods are limited, so exclusion and early detection are our only options, increasing the importance of rapid and accurate diagnosis, and encouraging collaboration between university, government, and private diagnosticians.View Poster
