Abstract
Rust diseases were found on safflower (Carthamus thinctorius) fields located in Euisong-gun Gyengbuk province in Korea. The infection rate of the disease in surveyed area was about 15% in 2001. 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 ${\times}$ 21~25${\mu}m$ in size. Teliospores were chestnut-brown in color, ellipsoid or ovoid in shape and 35~40 ${\times}$ 27~33${\mu}m$ in size. Pedicels were non-color of limpidness in color and 15~30${\mu}m$ in size. The causal fungus was identified as Puccinia carthami, based on morphological charateristics. This is first report on the rust of safflower caused by Puccinia carthami in Korea.
