Officials find emerald ash borer in Henry County

Jul 11, 2014

MOUNT PLEASANT (AP) — Officials say larva found on a tree in Henry County has been identified as an emerald ash borer.
A team that includes officials from the Iowa Department of Agriculture and Land Stewardship said in a news release Friday that the larva was found in a tree in Mount Pleasant. Additional information was not released.
The discovery means the insect has been found in ten Iowa counties. State entomologist Robin Pruisner says the larva’s discovery in July means there’s no “safe time” for moving firewood in Iowa.
A statewide quarantine that restricts the movement of hardwood firewood, ash logs, wood chips and ash tree nursery stock out of the state into non-quarantined areas was issued in early February. It remains in place.

Applying a systemic insecticide to the soil in mid-April to mid-May can be effective against ash borers. These insecticides are sucked up by the tree's roots and distributed throughout the entire tree. Imidacloprid is mixed with water and poured over the soil surrounding the trunk. Avoid applying imidacloprid to extremely wet or dry soil and remove any mulch from around the tree prior to application. This can decrease its effectiveness.
