There are no good sources of resistance in tomato for CMV, PVY, or TEV, so other control strategies must be used. Maintain a distance of at least 30 feet between susceptible crops, weeds, or other susceptible plants, including those in ditch banks, hedge or fence rows, and other locations. 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. Minimize plant handling to reduce the amount of virus spread mechanically. For more information , contact your county Extension office.
