Disease guide

A distinctive bright-yellow mosaic develops on leaves. Often fruits are mottled and distorted.

AMV has a wide host range among dicotyledonous plants. Infections generally occur when peppers are grown near alfalfa fields. The virus is transmitted by many aphid species in a non-persistent manner. Viruliferous aphids spread the disease rapidly within a field for very short periods of time.

To best manage AMV, avoid planting peppers near alfalfa fields. There is no effective chemical control of this disease because aphids immediately transmit the virus by feeding on infected plants. This virus can be transmitted mechanically and by seed. There is currently no resistance in commercial pepper cultivars.
