No biological vector is described for this virus.
Symptoms are leaf mottling, blistering and distortion with stunted growth in cucumber.
Cucumber fruits are usually symptomless. In watermelon, the virus induces slight leaf mottling and dwarfing, but can cause serious internal discoloration and decomposition of the fruit. This system shows no cross-reaction with healthy cucurbits. It also gives no cross-reaction when tested with odontoglossum ringspot virus, pepper mild mottle virus and tobacco mosaic virus.
