Ash borer found downstate
Posted November 06, 2008 10:00 pm
SPRINGFIELD -- The Illinois Department of Agriculture has expanded its emerald ash borer quarantine area to include all or part of three central Illinois counties.
Woodford and McLean counties and part of Marshall County was added by the agriculture department to the quarantine area because the invasive insect was detected in those areas.
A total of 21 counties now are fully or partly quarantined.
The adult borer feeds on ash foliage. But insect's larvae feed on the inner bark, disrupting the tree's ability to transport water and nutrients, killing the tree over a span of three to five years.
The quarantine prohibits the movement outside the affected counties of ash trees of any size, ash limbs, branches and bark.
