Abstract: | In Great Britain, fungicides are used in the forest only for the control of root and stem rot, caused by Fames annosus. In forest nurseries they are erriployed on a small scale to control damping-off, grey mould (Botrytis cinerea), needle-cast of pine caused by Lophodermium pinastri, needle-cast of larch caused by Meria laricis, needle blight of Western red cedar (Thuja plicata) caused by Didymascella thujina, and oak mildew (Microsphaera alphitoides). |
