Cucumber Mosaic Virus

Cucumber mosaic virus disease of peppers is worldwide. There are a number of different strains, but all are capable of infecting pepper plants and differ only in symptoms. The age of a plant at the time of infection strongly influences what types of symptoms are manifested. The initial flush of symptoms typically includes a chlorosis of young leaves that may occur over the basal portion of the leaf or over the entire leaf. Oak leaf and ringspot patterns may develop on these leaves as the plant ages. As new leaves emerge, these leaves develop a chlorotic mosaic pattern that tends to encompass the entire leaf.
