Why Are My Green Pepper Plants Leaves Curling Up?

The mosaic virus causes green pepper leaves to curl and become discolored. The mosaic virus is often associated with tobacco crops, but it infects dozens of plants and garden vegetables. The mosaic virus is a common disease, but simple precautions can keep green peppers from becoming infected.

The Virus

The mosaic virus, also know as the tobacco mosaic virus, is found worldwide and can infect 150 different crops and plant species, according to plant pathologists F. L. Pfleger and R. J. Zeyen at the University of Minnesota. The mosaic virus is one of the most common causes of viral infections in green peppers and other crops grown in North America.

Symptoms

Curled leaves, stunted plants and yellowed, spotted leaves are signs that a pepper plant is infected by the mosaic virus, according to Charlie Nardozzi of the American Gardening Association. The virus can also cause green peppers to wrinkle and develop small bumps or dark spots.

  • Curled leaves, stunted plants and yellowed, spotted leaves are signs that a pepper plant is infected by the mosaic virus, according to Charlie Nardozzi of the American Gardening Association.

Common Misconceptions

Gardeners sometimes confuse the symptoms of the mosaic virus with the affects of air pollution, herbicide or nutritional deficiency. The virus almost never kills green pepper plants but will lower the quality and yield of the fruit.

Control

There is no known chemical treatments to prevent or cure the mosaic virus. Plants are infected by the virus for life, and infected plants should be removed from the garden. The virus is often spread by insects like aphids, so pest control is one of the most popular preventative measures against the virus.

Garden Tips

Nardozzi suggests that gardeners should prevent the mosaic virus from infecting green pepper plants by controlling insect populations, avoiding tobacco use while in the garden, frequently washing hands with soap and water and destroying any infected plants.

Curling Leaves On Green Beans

Cucurbit leaf crumple virus is a disease that affects squash, cucumber, muskmelon, pumpkin, watermelon and bean. This disease causes leaves to curl and become thick and warped. Avoid whitefly infection in green bean plants by avoiding planting new crops near older crops that have already been infested with cucurbit leaf crumple virus. The leaves of an infected plant will also be long and more narrow than healthy leaves. Plants with BCMV produce fewer than normal beans. Aphids may be destroyed through use of pesticides, but use of pesticides on aphids is discouraged because these same pesticides may kill beneficial insects as well. Aphids may also be controlled with predatory insects like lady beetle and lacewing. Secure the paper to the ground by covering the edges with soil.
