Sycamore Anthracnose is a tree disease that is caused by the fungus Apiognomonia veneta. While rarely fatal, the disease negatively affects the look of the tree and, with repeated years of infection, can affect its overall health. The first symptom is often leaf loss occurring in early Spring. Cool, wet weather will aggravate the spread of this disease.
In the beginning years of this disease, the tree recovers on its own and quickly regenerates new leaves. However, this cycle repeats itself and leads to the development of a growth habit known as “witches’ broom.” Frequent loss and the regrowth of leaves leads to this atypical growth that resembles a broom. By now, the general health of the tree has also declined as the sugar reserves are being exhausted.
To stop this vicious cycle and to nurse the tree back to health, a two-fold approach is recommended. On one hand, the tree is injected with a fungicide that moves up into the small one- and two-year-old branches where the disease tends to overwinter. In addition to the injection, a soil treatment is recommended with a mixture of fertilizer, bio-root stimulants, phosphite, and a systemic biological fungicide.
