How do you treat birch tree disease?

Fungicide or pruning are ways to treat disease of birch trees (Betula spp).

Specifically, birch tree disease tends to refer to anthracnose or canker. Anthracnose requires the application of a fungicide spray at budbreak or the first sign of disease, whichever comes first. Effective active ingredients range from chlorothalonil to thiophanate methyl. Fallen leaves need to be buried or burned. Burning or burying of diseased parts also is the only control for canker, which demands the removal of all affected tree parts below the canker site.
