Brand and Common Canker symptoms on Rose
Brand and Common
Cankers (fungi - Coniothyrium spp.): Plants weakened by other diseases
or adverse growing conditions may be more susceptible. Organisms invade stems
and cause cankers (dead tissue surrounded by living tissue) to form. These often
girdle the stem and tissue past the point of infection is killed. Cankers are
light brown in color. Prune infected limbs and twigs being sure to cut well below
the diseased tissue. Keep plants free of other diseases.
