A set of trees outside of a Linden Hills condo building got special treatment Thursday with injections of a chemical to prevent Emerald Ash Borer.

Six trees at the Condos at Lake Harriet were injected with TREE-age Insecticide through small holes drilled in base.

"From there the water that's going up the tree is carrying the material up the tree, and within about four days on average the material is dispersed among the canopy of the tree, protecting it from EAB," said Jeff Palmer, Upper Midwest Regional Technical Manager with Arborjet.

This summer, the Minneapolis Park Board decided to cut down and replace five thousand ash trees a year for the next eight years because of Emerald Ash Borer. Cities like Milwaukee and Chicago have used TREE-age on tens of thousands of trees.

"TREE-age is a chemical that works, it's been proven through university studies. The concern we have is do we need to start treating trees if we are already in the time-frame where we think we can control the removal and the replacements," said Ralph Sievert, Director of Forestry for the Minneapolis Park and Recreation Board.'

TREE-age costs the average homeowner between $50 and $75 a year. The treatment lasts for about two years.
