Dutch Elm Disease

What is it?

An aggressive fungal disease that invades water transportation cells and produces toxins. The tree reacts by cutting off water to the crown to stop the spread of fungus.

How do we treat it?

We inject Alamo fungicide into the base of the tree, this provides 3 years of protection for your tree. Sometimes root trenching is required.

What to look for

  • Irregular leaf drop
  • Olive colored spots
  • Yellow dropping leaves


  • Wilting of branches
  • Leaves turn dull green, yellow and become dry and brittle
  • Canopy dieback top down

Treatment and Prevention

  • Systemic injection using Alamo with the Tree IV system
  • Allows full protection throughout the tree tissues and canopy
  • Does not prevent root grafts
