Herbicides are Effective for Reducing Dense Native Warm-season Grass and Controlling a Common Invasive Species, Sericea Lespedeza

SEAFWA Journal Volume 3, March 2016

Practices within the Conservation Reserve Program promote planting native grasses and forbs to improve habitat for northern bobwhite (Colinus virginianus) and other wildlife. However, native grasses often become dense and stands can be invaded by undesirable plant species that reduce habitat quality. We investigated three herbicides (clethodim, glyphosate, and imazapyr) at two rates to reduce native-grass density and five herbicides (aminopyralid, fluroxypyr+triclopyr, glyphosate, metsulfuron-methyl, and triclopyr) at two rates to control sericea lespedeza (Lespedeza cuneata), a common...

Effectiveness of Three Postemergence Herbicides in Controlling an Invasive Annual Grass, Microstegium vimineum

SEAFWA Journal Volume 2, March 2015

Effective control of Nepalese browntop (Microstegium vimineum) is important to land managers in the eastern United States because invasions can suppress native vegetation, thus decreasing vegetation diversity and habitat quality for many wildlife species. We evaluated the effectiveness of herbicides with varying selectivity (glyphosate, imazapic, and clethodim) at full rates and half rates (based on labeled rates for annual grass control) on the control of japangrass and their effects on non-target vegetation. We conducted our experiment in three forested areas in east Tennessee. We...
