First Report of Tomato Yellow Leaf Curl Virus in Greenhouse Tomatoes in Kentucky

P. B. de Sá, K. W. Seebold, and P. Vincelli

August 2008


Tomato yellow leaf curl virus (TYLCV) was identified for the first time in the United States in Florida in 1997 and has since been reported in other states. During 2005 symptoms typical of geminivirus infection were observed in a tomato greenhouse production system in Jefferson Co., KY. A nucleic acid-based pathogen detection approach was used and TYLCV infection was confirmed in tomato plants collected from the greenhouse and in symptomless Acalypha ostryifolia growing outside the greenhouse. This find raises concerns regarding the introduction of TYLCV to the state in infected transplants or in viruliferous whiteflies transported on infested plants, and its potential impact on economically important crops in the state.
