The outbreak of the "yellow dwarf" disease of soy bean plant caused by the soy bean nematode, Heterodera glycines, was commonly observed in the volcanic ash soil in Hokkaido. In 1954,this disease occurred in the peat soil at Ebetu, Hokkaido. A survey was made in this field, where three patches of disease appeared. Soy bean plants and soils taken from the inside and outside of these patches were examined with regard to the growth of plants and the nematode populations respectively. It was thought that this disease is due to the increased nematode population in clayey loam rich in humus having been mulched on peat soil surface.
