TERMINAL FUNGUS AFFECTING BUR OAK TREES IN IOWA
(Atlantic) You've likely heard of emeral ash borer, but now there is a new fungus that could be much more damaging to Iowa's trees. Bur Oak blight is what the disease is called, and Bill Drey with the Cass County Extension Office says it is a fungus spreading into Iowa from Wisconsin and Minnesota that causes the leaves to fall off of Bur Oak trees much earlier in the summer than they normally would. Trees can be either sprayed or injected for treatment to the fungus. The fungus does not necessarily kill the trees but over time it can be very detrimental. Bur Oak trees can be found in all 99 counties in Iowa.
