ResumoAbstract Stone fruit tree apoplexy in Greece is often caused by Phytophthora spp. Two types of Phytophthora apoplexy of stone fruit tree can be distinguished, one occurring during the hot summer period and usually caused by P. cactorum (Leb. et Cohn) Schröt. or P. citrophthora (R. et E. Smith) Leonian, and a second occurring in winter or early spring, and caused by P. syringae (Kleb.) Kleb. or sometimes P. megasperma Drechsler. Inoculation tests showed P. syringae to be highly pathogenic to apricot and almond, whereas certain clonal rootstock material showed resistance. Measures of control against Phytophthora attacks are given.
