About Emerald Ash Borer

The Emerald ash borer has been compared to Dutch elm disease (DED) for many good reasons. At one time elm trees dominated the urban landscape and provided necessary shade and beautification to the cities. Ash trees and Norway maple were planted to replace elm once they were victim to DED. It was an invasive pest which killed the elm, now it is an invasive pest which is taking its toll on the ash trees. Clearly, when replacing elm, or ash, consideration should be on planting diversity in tree species, so never again will one pest have such a serious affect on the canopy within cities.

Life cycle of EAB (see photo gallery)

Recent research shows that the beetle can have a one or two-year life cycle. Adults begin emerging in mid to late May with peak emergence in late June. Females usually begin laying eggs about 2 weeks after emergence. Eggs hatch in 1-2 weeks, and the tiny larvae bore through the bark and into the cambium – the area between the bark and wood where nutrient levels are high. The larvae feed under the bark for several weeks, usually from late July or early August through October. The larvae typically pass through four stages, called instars, eventually reaching 26-32mm in size. Most EAB larvae overwinter in a small chamber in the outer bark or in the outer centimeter of wood. Pupation occurs in spring and the new generation of adults will emerge in May or early June, to begin the cycle again.

About Tree Injections

Forestree Care only uses TreeAzin for injecting into trees as protection against the Emerald ash borer, using the Ecoject System.

Efficient:
Rapid set-up, portable and no wasted pesticide.
Rapid uptake and translocation through tree.

Safe:
No-spill possible, minimal risk of exposure.

Operational Efficiency:
Rapid injection times, multiple trees can be treated at same time.
At very low doses, TreeAzin inhibits emerald ash borer larval development, and prevents adult beetle to emerge from the tree.

Formulation of TreeAzin:
It is a systemic bioinsecticide.
Developed and owned by the Canadian Forest Service and under worldwide licence to Bioforest Technologies.

Formulated with azadirachtin, a natural product from the tropical Neem tree seeds.
