Summary Phytophthora cactorum, the causal agent of beech seedling blight, can kill Fagus sylvatica seedlings within a few days. Eight isolates of Phytophtbora cactorum and one isolate of Phytophtbora citricola were tested for their pathogenicity towards beech seedlings derived from eight different registered stands. The P. citricola isolate proved to be more aggressive than all the P. cactorum isolates, although there were significant differences among the latter. The influence of the seed source was less sever than that of the fungi. Regions of provenance generally had less influence on disease development than fungal isolate but differences in susceptibility among sources were important in the interaction between isolate and source.
