First report of Tomato chlorosis crinivirus in Morocco
In Morocco, tomatoes grown under protected conditions already face numerous pests and diseases, and during the last decade further introductions have been recorded. Tomato yellow leaf curl begomovirus (EPPO A2 quarantine pest) and Cucumber yellow stunting disorder crinivirus (EPPO Alert List) were reported for the first time, respectively in 1998 and in 1999. In 2000, Tomato chlorosis crinivirus (EPPO Alert List) was found for the first time. It is stressed that these invasive species are now complicating the IPM programmes currently used in tomato production. Tomato chlorosis crinivirus is now widespread in protected tomatoes grown in the Souss Valley, where it caused serious damage in 2002. However, the severity of symptoms and damage varied according to tomato cultivars (ranging from mild to very severe symptoms). The situation of Tomato chorosis crinivirus in Morocco can be described as follows: Present, found for the first time in 2000, widespread on protected tomatoes in the Souss Valley.
