Abstract:
A new disease, causing mortality of Italian cypress (Cupressus sempervirens) trees cv. 'Totem', was observed in an Israeli nursery. Fusarium compactum was isolated from cankers, and its pathogenicity was confirmed by Koch's test. The fungus readily formed conidia and chlamydospores in PDA culture. Growth of F. compactum was fastest at 26-30°C. Artificial inoculations genera: Cupressus, Juniperus, Tetrachnis, Thuja, Cedrus and Pinus. Canker development was significantly enhanced when extreme water stress was imposed on cypress saplings prior to inoculation.
