Tree / Plant Health - Emerald Ash Border



Walker tree service has three different plant protection products to treat your ash trees to protect them from EAB.  Because each of these products is used at different times of the year, Walker tree service can create a schedule for maximized effectiveness. If a tree is properly protected and receives treatment early, the success of sustainability is high.  The idea is to protect the tree early before damage does occur.


The condition can be effectively managed if you currently have EAB damage, in most cases.  EAB was recently discovered in our area.  The experts have speculated that EAB has been in our area for 5 to 6 years.  Control is crucial to prevent the spread of EAB.

Trees at Risk

All native ash trees, including green, white, black, blue, and pumkin ash.

Signs of Damage
Symptoms of an early infestation can be hard to diagnose. Be on the lookout for multiple declining ash in a given area and D-shaped exit holes that are approximately 1/8" in diameter. As an infestation progresses, small vertical splits in the bark can be seen on twigs or the main trunk and woodpecker holes may be present on trees. Trees may die in 2-4 years or less
Physical Apperance
- Typically the top 1/3 of crown shows dieback and thins.Trees appear to lose about 30% to 50% of their canopy after 2 years of infestation
- As the tree declines , epicormic shoots form at the interface between healthy and dead tissue anywhere in the canopy
- Distinct "S" shaped, frass filled, larval galleries taht can range from 4-20" in length etch the xylem and phloem
- Adults are slender and can be 1/4" to 1/2" in length, they are dark metallic emerald green
- Larvae range in size 1-1 1/4" in length with pincer- like appendages on the last segment
