Growth of Phytophthora infestans (Mont.) de Bary on Artifical Media

Article metrics


IT appears from the literature on Phytophthora infestans that many workers have had difficulty in growing this fungus and in obtaining a supply of sporangia. The fungus grows and fructifies well on potato leaves and tuber slices, but such cultures require frequent renewal. Recently Snieszko et al.1 in the United States described various media which supported growth, particularly a cereal grains – peanut hull mixture upon which the fungus spored freely. Peanut hulls are not readily available in Great Britain.
