City treats Ash along Principale

A handful of Ash Trees in Aylmer are not fully infected with the Emerald Ash Borer insect. This devastating invasive species has caused most Ash to die off. City workers are pictured here treating Ash at the corner of Principale and Frank Robinson Streets, July 16. The treatment consists of injecting TreeAzin, a systemic insecticide, seen along the
bottom of the tree in white
cartridges.  (LR)
