Cucumber Mosaic Virus
Cucumber Mosaic Virus :
Tomatoes infected with the cucumber mosaic virus develop a slight yellowing and mottling of the older leaves. Expanding leaves typically become twisted, curl downward, and develop a "shoestring" appearance as a result of a restriction of the leaf surface to a narrow band around the midrib of the leaf. Diseased plants are stunted and produce small quantities of fruit.
Control: Virus diseases cannot be controlled once the plant is infected. Avoid planting tomatoes next to cucurbits, spinach, or other vegetables and flowers susceptible to these diseases. Control of aphids will help reduce the likelihood of cucumber mosaic.
