WORTHINGTON (KMHL) – The Emerald Ash Borer has been discovered in southwest Minnesota.

The Minnesota Department of Agriculture is placing Nobles County under an emergency quarantine after the emerald ash borer was discovered in the city of Worthington.

“Many of our recent emerald ash borer finds have been along major roadways, such as this find along Interstate 90 in Worthington,” said Director of MDA’s Plant Protection Division, Mark Abrahamson. “We can see how this insect and other destructive pests are often moved through human assistance.”

The emergency quarantine intends to limit the movement of firewood and ash material out of the county.

“To protect our ash trees, Minnesotans and visitors to our state must continue to be vigilant and obey quarantines limiting the movement of firewood and other ash products around the state,” said Abrahamson.

A total of 19 Minnesota counties are now under quarantine to prevent the spread of the pest.
