Young leaves of slightly infected transplants turn bronze (purplish-brown) and later develop numerous small, dark spots. The bronzing of foliage may extend to large areas of the leaf surface. The bronzed areas may roll inward and the tissue often dies. Heavily infected transplants remain stunted. Shiny, dark brown streaks appear on stems and petioles. Growing tips of plants may die back.
