Most of us aren’t necessarily aware of the types of trees growing in our yard. They’re alive and beautiful, so we’re really not all that concerned about them. Not until some of the branches don’t fully leaf out in the spring, or when the next town over starts removing ash trees right and left, do we really take notice. Emerald Ash Borer (EAB) is an invasive, ash tree-killing insect from China that officially arrived here in central Illinois in 2014. First discovered near Detroit in 2002, by 2007 EAB had killed 25 million ash trees. By 2012, 250 million were gone. At the end of this 2015 season, death by EAB may approach one billion ash trees, mostly in the Midwest.
Within the next several years EAB will kill most the ash trees in central Illinois that are not appropriately protected. EAB moves and kills very, very quickly. Worse, it is typically present at low, undetectable levels years before being “officially” detected anywhere. The right insecticide, applied properly and timely, will prevent EAB from damaging an uninfested ash tree, or exterminate light to moderate infestation, and save the tree. These insecticidal protocols, if maintained, will prevent destruction of an ash tree by EAB indefinitely. Here in Sangamon, Menard and Logan counties, EAB is almost certainly present in every township and city. Time to begin preventive treatments is now, this 2015 season, after the ash trees’ leaves are fully open and proper assessment for any individual ash is possible.
The Coalition for Urban Ash Tree Conservation, in a statement released in 2011, makes a compelling argument urging the preservation of the ash forest by means of certain insecticidal protocols. This statement is cosigned by the world’s leading researchers of insecticidal control of EAB, including entomologists at Michigan State University, Purdue University and Ohio State University where most of the major research is conducted. This short, informative ‘Coalition’ statement may be seen at:
Clanton Tree Company has in excess of 2,000 ash trees under its care, many first treated in 2006, months after EAB was first discovered in the northern suburbs of Chicago. Only three percent of these thousands of ash trees were lost to EAB while under Clanton’s care, and most because treatments did not begin as early as advised. Applying an appropriate insecticide preventively is always best, be it Tree-age, Safari, or imidacloprid.
Clanton Tree Co. saved the parkway ash trees in DeKalb, Illinois, beginning in 2012. Now, Dave Clanton is available to property owners in the counties of Sangamon, Menard and Logan for consultation and treatment. Telephone Dave at 217-862-4511, or e-mail him from this web site and make an appointment to meet and talk with him at your home about your tree. The most appropriate treatment protocol for your particular tree is best decided upon examination after the leaves are fully extended. Dave is headquartered in Petersburg this season during critical spring and summer treatment periods and available almost any time for free consultation, or treatment.
When Dave Clanton spoke to the Illinois Native Plant Society the night of February 14, 2008 the subject was EAB, which Dave already had experience fighting in the suburbs of Chicago.
