PFARR: Emerald Ash Borer

Emerald ash borer made all the headlines this past May when it was discovered in Saint Paul. Since then, not a lot has been said in the media. It has been estimated by some accounts that there are 10 million ash trees in the State of Minnesota and that it is possible that all of those trees except those that are treated could be gone in ten years or less. It's important to keep in mind that ash trees were a very popular replacement for elm trees that died from Dutch elm disease.

There are several different treatments that a homeowner can apply to their ash trees to prevent emerald ash borer. Any treatment must include the ingredient imidacloprid. The treatment must be done once a year, every year for the rest of the life of that ash tree. Right now and early spring are the best times of year to treat ash trees.

There is a lot more to know about this. For more information click here.

Make your day a good one.
