The typical symptoms of the disease appeared first as small white spots on the leaf and turn brownish, dark brown spores revealed on them. Uredospores were light brown in color, ellipsoid or spherical in shape and 21~23 × 21~25 mm in size. Teliospores were chestnut-brown in color, ellipsoid or ovoid in shape and 35~40 × 27~33 mm in size. Pedicels were non-color of limpidness in color and 15~30 mm in size.
