Grapes are susceptible to many viral diseases that may affect berry quality, cause vine decline, and premature vine death. Unlike in fungal and bacterial diseases, chemicals cannot control a viral disease. The most effective strategy to mitigate viral diseases in your vineyard is to start clean by planting clean vines, and utilizing appropriate insect control measures to maintain them, and removing virus-infected vines.
The following wine grape varieties have been tested free of major grapevine viruses by the most sensitive method and are available at the Missouri State Fruit Experiment Station:
