Cucumber Mosaic Virus
A "shoestring" appearance of the leaves caused by the reduction of the leaf to a central rib; plants considerably stunted, the internodes of the stems shortened, and the plants appear bushy; leaves are extremely deformed and have a green mosaic pattern. Infected fruit exhibit white-to-yellow rings, areas, or v-shaped line patterns and resemble tomato spotted wilt virus.
Virus has a wide host range including many vegetable crops, weeds, ornamentals and woody and semi-woody plants; transmitted by aphids; not seed transmitted, and does not remain infective long on hands, clothing or soil.
Cool conditions that favor aphid flights.
