The emergence of Phytophthora species as foliar pathogens of forest plantations

Abstract : Since the year 2000, the emergence of Phytophthora species as significant foliar pathogens of forest trees has challenged paradigms for the management of the diseases this group of pathogens cause within forest plantations. Phytophthora pinifolia, P. pluvialis and P . ramorum are all now recognized as having significant impact within conifer plantations in Chile, New Zealand and the United Kingdom, respectively, while other species including P. lateralis, P. kernoviae, P. fallax and P . captiosa have each been demonstrated as potentially significant pathogens of trees within forest plantations. The aerial nature of these pathogens in contrast to soil-borne activity of most Phytophthora species has seen them emerge rapidly with few limitations to their spread following establishment. This talk will discuss the recognition and emergence of Phytophthora pathogens impacting the foliage of plantation forest species with focus on Phytophthora pluvialis as the cause of a new disease, red needle cast on radiata pine and Douglas-fir plantations in New Zealand. An update will be given on the current status of the disease and responses by local foresters and researchers in managing the impacts of these pathogens of forest productivity
