Question of the Week – TSWV

This week, the question was: What is going on with this pepper leaf?

This pepper leaf is showing symptoms of a virus, likely tomato spotted wilt virus (TSWV). TSWV is an important virus of tomato, pepper, eggplant, peanuts, tobacco, etc. that causes significant yield loss to infected plants. Numerous ornamental and weed species are also affected. TSWV is transmitted from plant to plant by thrips as they feed. The best way to avoid TSWV is by growing virus-resistant plants when available. Such varieties may be found in the SE Vegetable Crop Handbook in the recommended varieties section of each crop. Click here to continue reading about TSWV.
