SUMMARY Fallen apple leaves from orchards at East Malling Research Station contained oospores of Phytophthora syringae , often in large numbers. Oospores identical in appearance were also observed in pear leaves but their incidence was less than in apple. The colonisation of fallen leaves by P. syringae is considered the principal means of inoculum accumulation in orchard soil and therefore of great importance in the epidemiology of the fruit rot caused by this fungus.
