Details on the situation of Tomato chlorosis and Tomato infectious chlorosis criniviruses
In 1997, unusual symptoms were observed on tomato crops in Málaga and Almería in Spain. Symptoms were characterized by interveinal yellowing of leaves and purple discoloration in some cases. The disease was associated with high populations of whiteflies. In 2000, Tomato chlorosis crinivirus (ToCV - EPPO Alert List) was identified as the causal agent. This virus was also found in 2000 in Tenerife and Gran Canaria (Islas Canarias). In 2001, another virus causing similar symptoms, Tomato infectious chlorosis crinivirus (TICV - EPPO Alert List), was identified on tomato crops in Benicarló (Castellón). From April 2001 to December 2002, a total of 196 samples of symptomatic tomato plants, collected from the main-tomato growing regions of Spain, were tested by RT-PCR for the presence of ToCV and TICV. ToCV was detected in 95 samples from: Alicante, Almería, Castellón, Gran Canaria, Mallorca (Baleares), Murcia, Sevilla, Gran Canaria and Tenerife (Islas Canarias). TICV was detected in 16 tomato samples from Alicante and Castellón. Both viruses were found in 3 samples from Alicante.
The situation of Tomato chlorosis crinivirus in Spain can be described as follows: Present, found in Andalucia (Almería, Málaga, Sevilla), Comunidad Valenciana (Alicante, Castellón), Murcia, Islas Baleares (Mallorca), Islas Canarias (Tenerife, Gran Canaria).
