Feature(s) |
One means of identifying annosus root disease is to incubate freshly cut sections of infected wood in a plastic bag to stimulate production of the asexual stage, Spiniger meineckellum (40x). |

CODIT is also applicable to root rots. A tree either rapidly stops the spread of infection, as shown in this pine infected by Fomes annosus, or it does not, letting the infection girdle and kill the root or butt. A cross-section was cut near the top of the dead area.... |
