CONTROL WOODY WEEDS
The following information has been compiled to provide suggestions about controlling undesirable woody plants, generally termed "brush," around the landscape with herbicides. In hunterdon County the most common problems are poison ivy and multiflora rose, but there are any number of other woody plants that may be weeds under certain circumstances. The challenge for the property owner is to control the undesirable plants without damaging or killing desirable plants.
From WEED CONTROL AROUND THE HOME GROUNDS, by Stephen E.Hart, Darren W. Lycan and John A. Meade, Assistant Extension Specialist, Program Associate and Emeritus Extension Specialist, Rutgers Cooperative Extension.
Many people move into new homes with recently cleared woods and discover later that weeds such as poison ivy, brambles and other vies and brush species are infesting areas around the home grounds.
There are several herbicides that can be utilized to clean up these problems for woody species such as poison ivy and honeysuckle as well as more tender plants such as brambles and Japanese bamboo Roundup (glyphosate) herbicide is suggested. Apply in the late spring after leaves have fully opened or in late summer/early fall prior to leaf drop. Roundup herbicide will kill desired plants if sprayed on their foliage. if poison ivy is growing in and around desired plants such as a hedge pull the poison ivy away from the hedge (do not pull the poison ivy out of the ground), lay it on the ground, and then spray the leaves with Roundup. Place several layers of newspaper under the poison ivy to prevent injury to any desired grasses. Allow the treated poison ivy to remain attached to the soil for 5 to 7 days so the Roundup can traslocate into the root system. On small infestations the Roundup solution can be brushed or sponged onto individual leaves. Be sure to treat as many leaves as possible.
When poison ivy is growing up trees, cut the vines at head height and allow the upper portion to die. Treat the lower portion with a herbicide specific for poison ivy (commonly available at a home improvement store or garden center) after the new leaves are fully expanded. In ten days remove the growth.
Free standing brush can be removed in several ways. The foliage can be treated with a herbicide specific for brush control (these herbicides generally contain the active ingredients 2,4-D or triclopyr) in the summer or the brush can be cut leaving a 12 inch stump. Immediately after cutting, threat the stump with a full strength Roundup solution or a herbicide specific for brush control. For maximum effectiveness perform this operation in the fall and if a brush herbicide is used apply fuel oil or kerosene.

Methods of application for brush control (check product label for proper use).
These treatments if properly applied allow the use of minimal amounts of herbicide introduced into the environment.
