Maintaining Early-successional Habitats Using a Metal Wick Herbicide Applicator

We tested the efficacy of an aluminum wick herbicide applicator, the Weed Sweep®, for control of hardwood and pine saplings, 1994-1996. We compared spring and fall applications in 1 trial and, in a second trial, tested 2 herbicide mixes: glyphosate mixed with either trichlopyr or imazapyr. Herbicides plots had 78% fewer sapling stems/ha than control plots (P < 0.006). May applications of glyphosate/imazapyr provided greater control of hardwoods but lower control of pines than September applications (P < 0.05). Also, glyphosate/imazapyr provided greater control of hardwoods than...
