Potato plants with TSWV may show dead (necrotic) spots or patches on the leaves. These can appear as concentric rings separated by green tissue, which may lead to confusion with target spot (early blight). Severely affected stems, and occasionally the whole plant, may die. Plants grown from infected tubers are severely stunted, with a rosette form of growth and dark green leaves.
