Species hybrids either created in the laboratory or evolved in natural environments are discussed in association with evolutionary issues and possible threats they may pose to agriculture, horticulture and forestry. It is suggested that sustainable control of such hybrids will depend on the better understanding of temporal and spatial aspects of genetic mechanisms and environmental factors that lead to the hybridisation process and thus the genetic diversity in <em>Phytophthora</em> populations.</p>1 aÉrsek, Tibor1 aNagy, Zoltán  uhttp://dx.doi.org/10.1007/s10658-008-9296-z
