Percentage germination of the conidia of Peronospora manshurica (Naum.) Syd. ex Gaum. was inversely proportional to their concentration on the surface of water agar. It appeared that the adverse effect of high concentration on germination was due to an inhibitor associated with the conidia. The inhibitor diffused readily in water, was lost after exposure to air for a few days, but accumulated when the conidia were stored anaerobically.
