First report of Tomato chlorosis crinivirus in Réunion
In 2004/2005, pronounced leaf yellowing symptoms were observed on tomato plants growing under protected conditions on the island of Réunion. Symptoms were characterized by irregular chlorotic mottling of the leaves, with red or brown necrotic flecks on the interveinal areas. In most affected glasshouses, reduction of fruit size and yield was observed. High populations of whiteflies were also observed. In March 2005, 20 symptomatic leaf samples were collected and tested by RT-PCR for the presence of Tomato chlorosis crinivirus (ToCV - EPPO A2 list) and Tomato infectious chlorosis crinivirus (TICV - EPPO Alert List). Results showed that these tomato plants were affected by ToCV. TICV was not detected. This is the first report of ToCV in Réunion. The situation of Tomato chlorosis crinivirus in Réunion can be described as follows: Present, first found in 2004/2005 on glasshouse tomatoes.
