Agenda:

• “An Oak Wilt Update: New Revelations in Detection and Management” – Dr. Dave Roberts
  • 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.
• “Herbicide Phytotoxicity in Landscapes and Nurseries: What’s in a Name?” – Dr. Dave Roberts
  • Herbicides represent important tools to manage unwanted plants (weeds) in Landscapes and Nurseries. Herbicides are especially efficient and efficacious in lieu of physical means. Unfortunately, mistakes do happen. And when herbicide mistakes happen, they often present HUGE problems for our industry. Mistakes may occur from supplier advice, our failure to thoroughly read and understand herbicide labels, notoriously confusing labels, uncontrollable variables such as weather, and misapplication, among other contributors. Manufacturers of herbicides sometimes market different active ingredients under the same brand name, leading to misunderstandings by professional applicators and lay people alike. This program will disclose some of The Plant Doctor’s experiences with herbicide toxicity to plants over the past year or so.
• “The Tree Doctor’s Diary: Recent Experiences from the Field” – Dr. Dave Roberts
  • In his role as Michigan’s Plant Doctor, aka “The Tree Doctor”, Dr. Dave is called upon every year by Nurserypersons, Arborists, Landscapers, Suppliers and the Public to solve perplexing plant problems in the landscape and nursery. These plant problems range from pests to diseases and from environmental issues to dilemmas from cultural inputs. In this interesting session, a variety of problem-solving scenarios will be presented in his interesting storytelling style that will not likely lull you to sleep. This is a must-attend program for those who want to learn some of the tips for “forensic analyses” in field diagnostics and problem solving for effective management of perplexing plant problems.
