Symptoms of CMV
-
The vector of the cucumber mosaic virus is aphids. Cucurbits are susceptible to the Cucumber mosaic virus.
-
Initially, water-soaked yellow spots develop on the leaves.
-
The spots grow rapidly and become irregular to circular with a light grey or white centre. The spots coalesce and turn into large lesions.
-
Plants become severely stunted and leaves become distorted.
-
When infected at the stage of flowering and fruit, there is a huge reduction in yield due to malformation of the fruit.
-
Eventually, the leaves dry up and the plant dies.
