The two viruses we most often detect in dahlias, Tomato spotted wilt and Impatiens necrotic spot viruses, are transmitted by thrips and by propagating infected plants. Tomato spotted wilt virus is more common in dahlias than impatiens necrotic spot virus. Both can cause many symptoms, including mosaic patterns on leaves, distorted leaves, stunted plants, dead stem sections, spots and ringspots.
