Host range and distribution of Pythium myriotylum and unidentified Pythium sp. (Pythium sp. A) which cause the monoculture injury of bean and soybean plants in Hokkaido Prefectural Kitami Agricultural Experiment Station were investigated. Both P. myriotylum and Pythium sp. A were pathogenic to bean, soybean and sugar beet plants among seven rotation crops. They were pathogenic to pea plants as well as bean and soybean plants. The former was pathogenic to adzuki bean plants. P. myriotylum and Pythium sp. A were infrequently isolated from the stunted bean roots in twenty fields and from soils of twenty-four fields of various crops in Hokkaido by indirect method using rye seedlings. These results suggest the host range and distribution of P. myriotylum and Pythium sp. A are limited.
