Powdery scab situation
Potato tubers with scab lesions were found in several regions of Gangwon province during disease surveys
in 2000 and 2001. The lesions appeared as shallow scabs with torn and raised skin around the priphery
of the lesions. The causal organism was identified as Spongospora subterranea based on morphological
characteristics using light and electron microscope. This is the first report of powdery scab in Korea (see
reference list).
Research
Ten cultivars of potato were evaluated to select resistant cultivars against powdery scab. Among them,
Jowon, Superior and Atlantic were resistant, while Sephody, Gawon and Irish Cobbler were susceptible.
