Anthracnose nose in maple trees

Asked June 19, 2019, 4:43 PM EDT

Our two backyard [~6 years old, October Glory] maple trees have been diagnosed with anthracnose (they've had it for two years). --an injection treatment has been recommended - what chemical would we use? I'd like to hear your thoughts on the success rates of the chemical approach, and a site sanitation approach. Thanks in advance for your help!

We did have conditions at bud break for anthracnose and the image looks just like it. You can read about all the options here:

As for injection I would go with the Tebuject and not the Phospho-jet materials. Best to have an arborist help you out with that next spring. Multiple tactics are best rather than any one thing. Good luck.
