Emerald Ash Borer

     We have been busy treating and removing Ash trees throughout the golf course.  Emerald Ash Borer has done considerable damage to all Ash species. It has been in Missouri for about 4-5 years now.  It is widespread throughout the state.  We are treating our healthy trees with a insecticide injected directly into the tree. That gives our trees  3 years control.   Any Ash tree with 40% or more of canopy loss is being removed.  We have removed 11 trees so far and we have at least 6 more to take out.

This is the adult Emerald Ash Borer.  They bore into the Ash tree and lay eggs.  The larvae hatch and feed just under the bark killing the tree.

 Notice this tree hardly has any leaves.  It was removed
  
Staff cleaning up.

Injecting insecticide directly into Ash Tree.  It is a tree IV.  This will give 3 years control of Emerald Ash Borer.
