First report of cucurbit yellow stunting disorder crinivirus in Lebanon
In Lebanon, a recent survey carried out in the major cucurbit-producing regions has showed that besides well known mosaic-inducing viruses, crops often showed severe yellowing of the leaves. Symptoms started as interveinal mottle on the older leaves and developed into severe yellowing as the leaves became older. This disorder was especially observed in cucumber, melon and squash crops grown under plastic tunnels. Its incidence, in autumn crops reached up to 100 % in several locations along the Lebanese coast. Yield reduction of 40-60 % have been reported by farmers. The presence of cucurbit yellow stunting disorder crinivirus (EPPO Alert List) was detected in symptomatic samples. This is the first report of this virus in Lebanon. The status of cucurbit yellow stunting disorder crinivirus in Lebanon can be described as: Present: in major production areas.
