Herbicides Commonly Used for Controlling Undesirable Trees, Shrubs and Vines in Your Woodland
The removal or deadening of less desirable trees, shrubs and vines is an important management tool used by many woodland owners to help achieve management objectives. At the same time, shrubs and vines that pose a threat to human health (such as poison ivy) can be removed. This fact sheet presents the commonly used herbicides labeled for use with each technique, example brand names and manufacturers, and a brief summary of label recommendations for use.

Gypsy moth is an invasive insect that defoliates trees. It hosts on oak, spruce, hecklock trees and many more. A population of the European gypsy moth (Lymantria dispar) was discovered in June 2014 in the Greater Cincinnati region.
The infestation is located within the Ohio Department of Agriculture (ODA) gypsy moth "eradication zone." As with the discovery of any non-native pest that is targeted for eradication, there is always the possibility that satellite infestations have developed prior to the discovery of the main infestation. We need your help with discovering and reporting any undetected satellite infestations. Click here to learn more about the signs to look for regarding Gypsy Moth.
If you find gypsy moth caterpillars in the Greater Cincinnati region, please report it immediately to Gigi Neal, OSU Extension Clermont County (513-732-7070); Joe Boggs, OSU Extension Hamilton County (513-946-8989); or John Day, ODA Nursery Inspector.
Asian Longhorned Beetle (ALB) has 3/8” exit holes the size of a wooden pencil that are perfectly round and will go directly into the heartwood of the tree. A pencil placed inside the hole will go in approximately 2” deep. ALB can affect the following trees: maple, horse chestnut, mimosa, birch, hackberry, katsura, ash, golden raintree, sycamore, poplar, willow, mountain ash and elm. There are quarantined areas in Clermont (as of 9/1/14 these areas include Tate Township, East Fork State Park, and portions of Monroe, Stonelick and Batavia Townships).
If you believe trees on your property have ALB, contact the local USDA ALB office at 513-381-7180. The office is located at 1761 State Route 125, Suite A, Amelia, OH 45102.
A list of trees that are affected by ALB
Emerald Ash Borer (EAB) has exit holes that are shaped like a capital “D” laying on its flat side and will just be under the bark of ash trees. Unfortunately, because EAB is so widespread across Clermont County, there are no programs or funding at this time to assist in treatment or removal of trees infected with EAB. Therefore, all treatment and removal is at the property owner's expense.
Extension recommends homeowners contact an ISA Certified Arborist (International Society of Arborists) to assist with assessment and treatment.

Ash Wood Utilization
"My ash trees are dying...what do I do?"
Background of EAB in Ohio
Because of EAB and ALB, you may have seen signs posted around the county stating "Don't Move Firewood." What does this phrase really mean? It means that you should do your part to not risk the further spread of an invasive pest by moving firewood from point A to point B.
Firewood should be harvested or purchased at the location you are burning a fire. You should not bring any extra firewood home with you when you leave your fire location. Here are a few guidelines for firewood management:
1. Buy firewood near where you will burn it (the general rule of thumb is that wood cut within 50 miles is too far and 10 miles is best)
2. Wood that looks clean and healthy can still have tiny insect eggs or microscopic fungi spores that will start a new and deadly infestation. Always leave it at home, even if you think the firewood looks fine.
3. Aged or season wood is still not safe. Just because it is dry doesn’t mean that bugs can’t crawl onto it!
4. Tell your friends not to bring wood with them; everyone needs to know that they should not move firewood.
ALB wood (including firewood) must remain in its quarantine zone. Because Clermont is an EAB-quarantined county, you cannot move ash wood outside of Clermont. In fact, the USDA has placed a quarantine on the entire state of Ohio preventing the movement of ash wood out of the state of Ohio.
