Oak wilt and Bur Oak blight are hard to differentiate from pictures. You may wish to have an onsite assessment by and arborist or you can send or bring a sample to the Plant Disease Clinic in St. Paul. The websites give information on the differences, how to find an arborist and how to submit a sample to the Plant Disease Clinic.
