An Oak Wilt Update: New Revelations in Detection and Management
Oak Wilt continues to spread in Michigan. The disease has infiltrated some communities so insidiously that it has become almost impossible to stop. Property owners are so confused with the array of management options and the cost estimates that they become indecisive about how to proceed. Community associations often become gridlocked. In these situations, the disease continues to spread and becomes far more difficult and costly to manage. Furthermore, mismanagement is not uncommon, leading to more costs and disease advancement.
This session will review detection methods for confirming Oak Wilt, including some new protocols, and the major management methods used to contain and eradicate Oak Wilt. A discussion of research from a variety of sources will also be presented.
