Host:burley tobacco (Nicotiana tabacum (burley type)
L.) Descriptor: Symptoms Description: The symptoms of CMV infection are quite striking and resemble those caused by other aphid-borne viruses and tobacco mosaic virus. Typical symptoms are mottling or mosaic of the young leaves, sometimes accompanied by stunted, narrow, or distorted older leaves. Scalding of infected leaves may also occur. Cucumber mosaic virus is transmitted by aphids migrating from infected weeds and vegetable crops. CMV is relatively rare in burley. Image type: Field Image location: United States
