Pythium aphanidermatum (Edson) Fitzp. patogen ogórków szklarniowych [Pythium aphanidermatum (Edson) Fitzp. a pathogen of greenhouse cucumbers]

Bogdan Nowicki


The infection of mature cucumber plants by Pythium aphanidermatum was stated in two greenhouses. Young cucumber plants from the stage of young seedling until the beginning of cropping were easily infected by the fungus when artificially inoculated. The mature plants were effectively infected only when high temperature (above 30°C) and high moisture conditions were provided. All 17 cucumber varieties tested were susceptible to infection. Morphology of the fungus is described for the first time in Poland.
