Step 4

Reference Comparison

Compare findings with known pest and disease profiles in our glossary

Step 5

Treatment Planning

Develop an appropriate treatment strategy based on the identified problem

Ash Tree Identification Guide

Proper tree identification is crucial for effective diagnosis and treatment. Learn to identify different ash species, particularly important due to Emerald Ash Borer threats.

Emerald Ash Borer Alert

In North America, Emerald Ash Borer has only been found in ash trees. All species of North American ash appear to be susceptible to this destructive pest.

White Ash

Fraxinus americana

  • Glaucous (pale) undersides of leaves
  • Flaky or peeling outer surface of twigs
  • Forest tree commonly found with Sugar Maple
  • Lighter colored leaf undersides compared to upper sides

Green Ash

Fraxinus pennsylvanica

  • Leaves similar in color on both upper and lower sides
  • Smoother twigs compared to White Ash
  • Pioneer species in riparian zones and disturbed areas
  • Most widely distributed of all American ashes

Black Ash

Fraxinus nigra

  • Grey, thick and corky bark even on young trees
  • Dark brown to blackish winter buds with velvety texture
  • Leaflets are sessile (directly attached to rachis)
  • Typically found in northeastern United States and eastern Canada

For Emerald Ash Borer control, Mauget recommends Imicide for effective, season-long protection.
