About Emerald Ash Borer
This metallic wood boring beetle was found in Detroit, Michigan and Ontario, Canada in 2002, and has continued to spread into neighboring states and eventually across the U.S. and Canada. The adult is a small, metallic green beetle only 10-15 mm in length and about 3 mm in width. The larvae live under the bark of the tree and feed in the vascular cambium. The adults typically emerge around June, leaving D-shaped exit holes in the bark. This ash tree insect briefly feeds in the canopy before reproducing and laying eggs in the twigs and branches.

Common Symptoms
EAB larvae live under the bark and feed on the vascular tissues. Larvae create meandering galleries through the phloem, vascular cambium and etch the xylem, effectively girdling the tree. Dieback of the canopy is a symptom of EAB larval infestation; as many as one half of the branches may die back as infestation progresses. The tree responds by sprouting new (epicormic) branches below the disrupted tissues. The bark will split over dead vascular tissues, and trees may die within only two years of the onset of symptoms.

Treatments

Independent studies strongly recommend that treatments be applied early, before extensive disruption to the vascular tissues occurs. Dieback symptoms should be <40%. Arborjet recommends treatment when EAB is detected in your area, but trees still appear healthy for best outcomes. Treat ash with IMA-jet® (imidacloprid) using the TREE I.V. system for high volume dosages or the QUIK-jet® or QUIK-jet Air® micro-injector for lower volume applications. IMA-jet will kill the EAB larvae inside the tree.

See the IMA-jet labels for dosage rate based on tree size.

To give the tree a greater health benefit, a follow-up application of NutriRoot is recommended, the specific formulation dependent upon soil type. When applied to the soil, NutriRoot®, will supply phosphorous, potassium, iron, manganese, humectants, humic acid and a low dose of nitrogen for healthy leaf and root development.

When to Treat
Treat ash if EAB is reported within 30 miles of your area. Do not wait for visible dieback in the canopy, as there is a significant delay between disruption to the vascular tissues and expression of symptoms in the canopy. Delaying Emerald Ash Borer treatment could result in canopy dieback or tree loss. Applications should be made in the spring, about 30 days prior to expected adult emergence; however, treatment may be applied during the growing season (May – September) to protect trees. Uptake of formulation is fastest when trees are actively transpiring after they have developed a full canopy. Emerald Ash Borer treatment in the spring will prevent the adult beetles from feeding and laying eggs in the tree, whereas summer treatment will kill the larval stage of EAB feeding under the bark. Make summer treatment applications in the morning when temperatures are moderate. If soil is dry, water trees prior to treatment. Injection in the fall (after leaves color) can protect the tree for the following season.
Trees need to be closely monitored for symptoms of EAB as infestation builds in your area. In general, applications are not made more than once a year.
