Situation of tomato yellow leaf curl geminivirus in Lebanon
Tomato yellow leaf curl geminivirus (EPPO A2 quarantine pest) is a serious pest in Lebanon. A recent survey has shown that field production of tomatoes during summer and autumn has been abandoned along the Lebanese coastal plains because of this disease which also severely affects greenhouse production. Screening studies for resistant tomato genotypes to tomato yellow leaf curl geminivirus are being conducted, and four cultivars have been found highly tolerant to the disease. For the detection of the virus, the authors have found that the tissue blot technique gave good results.
