If you follow the local news you have seen numerous reports about Emerald Ash Borer and it's destructive nature. This little pest is causing millions of dollars in damage to our trees and to our neighborhoods. Here at DMGCC we have a good population of ash trees. About a month ago a sub-committee was formed to look at and identify ash trees that are integral to our golf courses and ones the sub-committee felt should be treated and protected. Also golf course architect Tim Liddy has looked at those recommendations and has helped us with some of the decision making. The sub-committee, Green and Golf Committee and the Board of Directors all agreed that these trees should be protected.
The method of protection that we decided upon is injecting the tree with a product called Tree-Age (pronounced Triage). This injection treatment last 2 full years and it also protects the tree against other borers that do destructive things to ash trees. Iowa State University gives you a recommendation not to treat trees until the pest is 15 miles, however I spoke with our State of Iowa Entomologist and she felt that once a infestation of EAB is found, it has been there for a couple of years already. So chances are EAB is closer than you think and we felt that we needed to protect our investment here at DMGCC now rather than taking a wait and see attitude.
Over the next several weeks you will see members of the Greens Department working around some of our ash trees. While this product is a restricted use insecticide, the method that we are using is very safe and poses no risk to our golfers. Our staff members have been trained in the correct method of injection and it really is interesting to see the product go into the tree to protect against EAB.
