Potato is an important source of the virus for tomato and other solanaceous crops. The virus does not appear to be seed transmitted. Plant earlier to avoid high aphid populations that occur later in the season. Plant late settings as far as possible from fields used to produce early tomatoes and peppers. These areas can act as sources of viruses and aphids for subsequent crops.
Scout fields for the first occurrence of virus disease.
Where feasible, pull up and destroy infected plants but only after spraying them thoroughly with an insecticide to kill any insects they may be harboring. Use reflective mulches to repel aphids, thereby reducing the rate of spread of aphid-borne viruses. Monitor aphid populations early in the season and apply insecticide treatments when needed. Avoid planting tomatoes near potato fields. Use chemicals only according to the directions on the label.
