The leaves of infected plants become yellow or red between the veins, stunted, and rolled.
Symptoms generally occur on older leaves, while new growth continues to appear normal.
As the disease progresses, interveinal necrosis can occur and the leaves become characteristically brittle, thick, and crisp. Although the disease has the potential to cause severe losses to both fresh market and greenhouse-grown tomatoes, it generally causes minor losses. Avoid using infected transplants. Roguing of infected plants and general whitefly control may help reduce virus spread. The Regents of the University of California.
