Virus Diseases of Leafy Vegetables and Celery

Abstract

Lettuce, endive (escarole), spinach, and celery are members of different plant families, but share many of the same viral problems. In New York most of these crops are produced on organic soils, but they may also be grown on mineral soils. Because these crops are often planted near one another, the viruses or other agents infecting the crops are the same, and they are transmitted by the same insect vectors.
