Abstract
|
|
|
Three species of Pythium previously not recorded in Korea were found during 1975. Pythium spiuosum Sawada was isolated from diseased cabbage seedlings, P. nayriotylum Dreschl. was isolated from kidney bean and P. butleri Subramanium from cucumber, spinach, red bean and radish. Pathogenicity of isolates of P. butleri and P. myriotylum was confirmed in pathogenicity tests but P. spinosum appeared to be non-pathogenic.
Several isolates failed to sporulate satisfactorily on cornmeal agar and some produced degenerate oogonia after sub-culturing on this medium. Sunflower seed agar was found to be a suitable alternative medium.
The validity of previous records of P. debaryanum Hess in Korea is discussed.
