First record of Tomato chlorosis virus in Costa Rica
At the beginning of 2007, severe yellowing and chlorosis symptoms were observed in field-grown and glasshouse tomatoes (Lycopersicon esculentum) in Costa Rica. Large populations of whiteflies (several species including Trialeurodes vaporariorum) were also observed in affected crops. Laboratory analysis confirmed the presence of Tomato chlorosis virus (Crinivirus, ToCV - EPPO A2 List) in 9 samples out of 47 symptomatic samples collected from the Central Valley near Cartago. This is the first record of ToCV in Costa Rica. The economic impact of this virus on tomato crops has not yet been determined and studies are being carried out to determine its incidence.
The situation of Tomato chlorosis virus in Costa Rica can be described as follows: Present, first found in 2007 on a limited number of tomato samples from the Central Valley (near Cartago).
