Tomato spotted wilt virus in potatoes
This 3-page fact sheet describes the symptoms of Tomato spotted wilt virus (TSWV) in potato crops and the economic damage it causes. TSWV is spread by planting infected potato seed and by some species of thrips, including the most effective vector of TSWV, Western flower thrips (WFT). Measures to manage both the virus and its vectors are discussed. TSWV is most effectively managed by controlling the source rather than the vector. This 2-page fact sheet provides information on the background, symptoms, incidence and control of Tomato spotted wilt virus (TSWV) and the thrips species that spread it, including Western flower thrips (WFT).
