Bur Oak Blight

Bur Oak Blight (BOB), a serious leaf blight disease, has been discovered in New Ulm. This blight primarily occurs on naturally established Bur Oaks, and especially on mature trees. This disease will spread from tree to tree, but not all Oaks are seriously affected. Please read the "Pest Alert" about Bur Oak Blight below to learn more.

Bur Oak Blight should not be confused with Oak Wilt which is a completely different disease and nonexistent in New Ulm at this time.


If you have questions about your Bur Oak or one somewhere else, please contact the City of New Ulm Engineering office at 507-359-8245. We will have a certified diseased tree inspector look at it.
