LOUISVILLE, Ky. (AP) - Kentucky officials have ended a 30-county wood quarantine that was intended to contain the emerald ash borer.
The insects already have killed more than 25 million trees in the eastern U.S.
Agriculture officials told a Louisville newspaper the insects likely will now spread more quickly through Kentucky. But they also said the 30-county quarantine has been ineffective. And they said the federal government has more resources to deal with the problem.
The battle against the ash borer will now be left up to the U.S. Department of Agriculture. Because Kentucky is no longer quarantining those 30 counties, the entire state will join a large quarantine zone that includes Missouri, Illinois, Indiana, Ohio, Michigan and West Virginia.
Regulated ash-related products can only be moved outside the zone under certain conditions.
