The emerald ash borer, a tree killing pest spreading across the Midwest, has been found on the campus of Indiana State University. Despite the devastating effects the bug can have on tree populations, campus officials have a plan to battle the tiny menace.
The invasive species making its way across the Midwest and has been infecting trees in communities across the state. Until recently, its presence had not been seen in Terre Haute.
While evidence of the emerald ash borer has just now been seen on the ISU campus, ISU Landscape and Grounds Manager Stephanie Krull says university officials have known for a while that the tree killing pest was on its way.
“We actually had a treatment plan in place last year, and purchased the equipment and treatment chemicals last year,” she says. “We didn’t get a chance to use them, because the drought prevented that because the trees have to be cycling a lot of liquid in order to move the medicine around.”
Krull says the campus plans this spring to treat about a third of the trees around ISU.
“We’re going to work with Purdue researchers to do that process and they’re going to document and track our progress and hopefully things will go well and possibly even more than the trees we treat might survive,” she says.
Krull says the university has been planning to replace the dying ash with native shade trees grown on nearby tree farms to stop the ash borer’s spread.
Once an ash is infected with the bug, experts say it usually has only four to five years to live.
