Cucumber mosaic virus (CMV) severely infects sweet potato fields in Israel causing stunting, chlorosis, and yellowing of plants. Transmission of CMV to healthy sweet potato plants failed. Infection depends on the presence of a whitefly-transmitted agent and not on sweet potato feathery mottle virus, as reported previously.
