Forestry herbicides are a versatile, cost-effective tool that can be used in a variety of ways to help manage forest vegetation. In mature forests, herbicide treatments can be used to control interfering plants that prevent new seedlings from developing on the forest floor. In young forests, they can be used to reduce competition around selected trees, thus enhancing growth and survival of individual trees that provide wildlife food, wood products, and seed sources for future forests.
Field trials identified the effectiveness of various herbicides when applied to target trees using four manual application methods: 1) stem injection, 2) basal spray, 3) cut-stump, and 4) foliar spray. Research results provide guidelines for prescribing the proper herbicide , application method, chemical concentration, and treatment timing for various target species.
Manual herbicide application methods are especially suited for the small forest ownerships in the rugged Appalachians, where the use of mechanized methods is often limited by steep terrain. These methods enable forest landowners to control interfering plants and enhance desirable vegetation using safe herbicides with minimal training and inexpensive equipment.
