1. In the present paper we described the results of investigations on the adsorption of copper in conidia of Cochliobolus miyabeanus and the elution of copper.
2. Adsorption of copper by conidia took place more markedly in concentrated copper sulphate solution than in diluted one. In this case, conidia adsorbed copper in abundance showed low percentage of germination.
3. The degree of elution of copper from the conidia was judged from their germination per centage. When they were treated in hydrochloric acid solutions (pH 1 or 3), the elution occurred remarkably showing a good germination of conidia. In alkaline solution, however, the elution did not practically occur.
