Description
Summary:We initiated a study to determine the necessary rates of Journey® herbicide applied pre-emergence to reduce competition and allow establishment of native grasses. Native grasses are important components of prairie ecosystems that provide habitat for wildlife and quality forage for livestock. Spring application of 0.07 kg ai/ha imazapic + 0.18 kg ai/ha glyphosate, 0.09 kg ai/ha imazapic + 0.25 kg ai/ha glyphosate, and 0.11 kg ai/ha imazapic + 0.31 kg ai/ha glyphosate, commercially available as Journey® herbicide, and an untreated control were randomly assigned at each site. Plots were seeded within two weeks following herbicide application with a mixture of native warm- and cool-season grasses. Our results indicate that a pre-emergent application of 0.07 kg ai/ha imazapic + 0.18 kg ai/ha glyphosate can improve establishment of planted native grasses.
