The Minnesota Department of Agriculture has confirmed the finding of Emerald Ash Borer (EAB) in Apple Valley on January 21, 2016 after a report came in from the city. This is the first finding of EAB in Apple Valley, although it was found in neighboring Eagan during December 2014. Apple Valley is the third city in Dakota County to discover an EAB infestation, along with Eagan and Mendota Heights. If your property is within 15 miles of an EAB infestation, and you have a healthy ash tree that you do not want to lose, you should consider treating it with an insecticide.
We do have a soil drench product that we sell at Pahl’s that when applied annually will control the Emerald Ash Borer. Depending on the size and vigor of your ash tree, the uptake period can range from one week to three months for larger trees. For this reason, a soil drench should be applied 2-3 months before the expected pest infestation. This product is a preventative treatment to apply prior to the occurrence of insect damage. One soil drench treatment should be applied once a year during early spring to early fall. This product can be applied anytime except when the ground is saturated or frozen. If you did not apply an insecticidal soil drench last fall, we highly recommend that you apply it this spring as soon as the ground has thawed.
We will be attending a informational seminar hosted by the Minnesota Department of Agriculture regarding the Emerald Ash Borer. It is our intention to be as knowledgeable as possible on the identification and treatment of the EAB. This will aide us in helping you preserve your beautiful trees and prevent the spread of this nasty pest.
Please watch for more information in next month’s newsletter. We will be passing along what the Minnesota Department of Agriculture recommends that our community do to stop this pest. If you have any questions in the mean time, please feel free to give us a call. We will not stand by and watch the EAB destroy our trees!
