American Elm Health Care

Dutch Elm Disease is a lethal tree disease caused by an aggressive fungus.  Primarily transmitted by beetles,it feeds in the 2-4 year old branches.

To protect a tree from infection, Arbotect, a fungicide must be evenly and completely distributed throughout the branches. The best way to get such distribution is by macro-injection into the root flares of the tree.

The best candidates for fungicide protection are healthy, valuable elms. The injection process protects a tree for 3 growing seasons from infections by beetle carriers, after which time another injection is required.

Arbotect protects against Dutch Elm Disease infections by coating the vascular tissue of the elm where the fungus grows.  Thus, it is important the chemical becomes systemically distributed throughout the 2-4 year old branches in which the insects feed and spread infections.
