CMV – Cucumber Mosaic Virus

Type: Virus - Potyvirus

Cucumber Mosaic Virus is a world-wide virus disease that affects the growth of cantaloupes & melons, cucumbers, eggplants, gourds, peppers, pumpkins, spinach, squash, tomatoes, and watermelons. Symptoms include stunted or dwarfed plants, mottling, yellowing, distortion, and wrinkling of the leaves with the edges curling downward, and reduced growth rate and yields. The symptoms on leaves known as "shoestring" effect causes young leaves to appear narrow. The leaves will die and fall off, leaving part or most of the plant bare. The virus causes cucumbers to turn pale and gray, become bumpy and oddly shaped, and have a bitter taste. The virus causes peppers to have severe leaf damage with mosaic and necrotic rings. The peppers may have rings and spots. Tomato plants are usually stunted and have poorly shaped leaves and can cause partial or total crop loss. Plants infected with the virus have little or no marketable fruit. The virus can reduce yields and fruit quality. It is spread by aphids, seeds, and weeds. The virus overwinters in many perennial weeds. The infected plants should be removed to avoid further infestation. This virus cannot live in extremely dry conditions. The disease is favorable when temperatures are 79-89 F when aphid infestation is great. Symptoms usually begin to show in June. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year. Keep the fields weed free as infected perennials can harbor the virus. Proper tillage practices may be helpful in managing the disease. Insecticides for aphids are of limited value to control the disease. Spraying the tomato plants with mineral oil can delay the aphids from spreading the virus.The best option is to use disease resistant varieties.
