The infection court of Faba bean seedlings for oospores of Peronospora viciae f.sp. fabae in soil was determined. Soil naturally infested with oospores was placed as 3‐cm thick layers at four different depths relative to Faba bean seeds. Seedlings with downy mildew were obtained only from seeds sown in the middle of a 3‐cm layer of oosporeinfested soil. No infection was obtained from oosporeinfested soil placed more than 1.5 cm above or below seeds. Histological observations showed that the hypocotyl and first part of the main root were the most probable sites of infection.
