Enhancing Integrated Roadside Vegetation Management Along North Carolina Roadsides through Characterizing Herbicide Fate.

Vegetation management along NC roadsides must encompass comprehensive management programs in a fiscally responsible manner ensuring motorist and transportation worker safety. Synthetic pesticides are an integral component of roadside vegetation management; however, managers must utilize effective vegetation management programs without adversely affecting adjacent plants or vegetation including agricultural crops as well as environmental and human health. An assessment of existing practices as well as evaluation of new instrumentation and technology, which may assist field personnel to avoid adverse scenarios, is needed. Specifically, the proposed research will assess current vegetation management programs and practices and their effect on air and water quality, identify best management practices to minimize potential off-target movement, and devise training material for NC DOT field personnel to understand how to prevent and identify off-target movement.
