SYNOPSIS
Fungal diseases are responsible for severe losses of Pinus and Eucalyptus seedlings in South African forest nurseries. Pathogens such as Botrytis cinerea, Fusarium oxysporum, Rhizoctonia solani, Phytophthora cinnamomi, Cylindrocladium scoparium and Colletotrichum spp. are commonly associated with disease symptoms. Control can be achieved by means of cultural, chemical and biological methods, while ectomycorrhizae could also play an important role in resistance of seedlings to pathogens.
