The genus Phytophthora (Greek “plant destroyer”) includes many soilborne species which cause root and collar rot symptoms of herbaceous and woody plants including different forest trees. This review will focus on Phytophthora diseases of forest trees, as their significance has increased in recent years. Chlorosis, necrosis and wilt symptoms can be seen on leaves in the whole crown before the tree dies. However, death can take several years. All soil-borne Phytophthora species share a common infection cycle which is summarized in Fig. 1. Open image in new window Fig. 1. The infection cycle of soil-borne Phytophthora species
