Tomato Spotted Wilt Virus

Tomato spotted wilt virus, or TSWV is spread through nine different varieties of tiny winged insects called thrips. The disease affects tomatoes, but also celery, eggplants, peppers, lettuces, and pineapples, among others. Symptoms include bronze leaves, dark spotting, drooping leaves, stunted growth, and reduced yields. If a plant is affected early in the season, it will not produce fruit.
