Situation of vegetable viruses in Islas Canarias (ES)
In Islas Canarias (ES), the following viruses have been found on vegetable crops. Tomato spotted wilt tospovirus (EPPO A2 quarantine pest) is the most important virus disease and can be found in nearly all growing areas of tomato, pepper and lettuce, especially where crops are grown during the whole year under plastic houses. Potato Y potyvirus can be very damaging on winter tomatoes grown outdoor or under screenhouses. Symptoms of tomato yellow leaf curl geminivirus (EPPO A2 quarantine pest) were first observed in Tenerife in January 1993 on winter tomato crops grown outdoor. Other viruses of minor importance have been recorded on tomato, pepper and lettuce (cucumber mosaic cucumovirus-Carna 5, tomato mosaic tobamovirus, lettuce mosaic potyvirus, pepper mild mottle tobamovirus). On Cucurbitaceae, zucchini yellow mosaic potyvirus, cucumber mosaic cucumovirus, watermelon mosaic potyvirus 1 can be found. Finally, melon necrotic spot carmovirus and squash mosaic comovirus have been observed for the first time in 1992, in the northern part of Tenerife, on melon.
