Stop oak wilt this Spring
The Do Not Cut or Wound Oak Trees period runs from April 15th through July 15th. This is to prevent the spread of oak wilt (OW) disease. This is the most critical timeline when the Nitudulid beetle (aka picnic beetle, a native beetle) is most active, which is the primary way OW disease is spread in Michigan. The picnic beetle is drawn to the scent of an open wound on oaks for purposes of feeding on the sap. If the beetle has already come into contact with the OW fungus, the spores are introduced and a new infection site develops.
