Phytophthora megasperma is a species of water mould in the family Peronosporaceae. It is well known as a plant pathogen with many hosts. It often causes a plant disease called root rot.[1]
This is a poorly defined species which is generally called a species complex. Its name applies to water moulds of many forms, functions, and host preferences, many of which are actually different species which have not yet been separated and described.[2][3] Some species previously treated as part of the complex include Phytophthora rosacearum, P. sansomeana, P. sojae, P. medicaginis, and P. trifolii.[3] A form of P. megasperma is suspected to be a separate species when it is recognized to have host specificity, when it is found attacking just one host plant; alfalfa in the case of P. medicaginis, for example.[2]
