Abstract |
Rust disease was found on broad bean (Vicia faba) in several farmer`s fields located in Changseon-myon, Namhae- gun, Gyeongnam province in Korea. The infection rate of the disease in the surveyed area was 84.3% in 2002. The typical symptoms of the disease appeared first as small, white spots on leaves, stems and pods. Spots, then turn brownish, their edges rised slightly, and powdery mass of yellowish brown spores revealed on them. Severely infected leaves were eventually defoliated. Uredospores were light brown in color, ellipsoid or ovoid in shape and 24~38 × 21~26 mm in size. Teliospores were dark brown in color, ellipsoid or ovoid in shape and 22~42 × 17~27 mm in size. Pedicels were sienna to luteous in color and 52~116 mm in size. The causal fungus was identified as Uromyces viciae-fabae, based on morphological broad bean caused by Uromyces viciae-fabae in Korea. |
