CaneBlightThesymptomsofcaneblight(Coniothyriumfuckelii)caneasilybeconfusedwiththoseof... Cane Blight

The symptoms of cane blight (Coniothyrium fuckelii) can easily be confused with those of spur blight. Both diseases cause considerable damage to Michigan raspberries. The fungus can live for several years in cane debris left in the field. Spores release (both ascospores and conidia), and subsequent infection begins in the spring. Conidial infection continues through- out the growing season during rainy weather. Wounds from pruning, insect feeding or cane rubbing are the initial sites of infection. Brown or black infected areas extend down one side of the cane for several inches (Fig. 6B). Fruiting canes infected the previous season have light colored, cracked bark. Lateral shoots on infected canes grow poorly and may wilt and die during hot weather.
Control: Never prune during wet weather. To prevent infection, canes should remain dry for at least 3 days after pruning so wounds will callus. Prune out and burn infected canes in the spring.
