During April 2004, a 150 m2 dry bean plot growing adjacent to rust-infected soyabean at Cedara Agricultural Research Farm, South Africa, was observed to be infected with 2 distinct rust types. Common bean rust (Uromyces appendiculatus) with reddish-brown uredinia and black telia was readily identified. A second rust with smaller sporulating uredinia and (1.0-1.5 mm2), which were grey in appearance, was also found.
