Imazapic provides 2-year control of weedy annuals

Abstract:

Imazapic applied at 105 g active ingredient (ai)/ha (1.5 oz ai/ac) eliminated nonnative annual forbs for a single growing season and significantly reduced the production of a nonnative annual grass, cheatgrass (Bromus tectorum L. [Poaceae]), for 2 growing seasons following treatment, without negatively affecting native plant species in a northern Nevada fuelbreak. Imazapic may prove useful in maintaining fuelbreaks created in Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young [Asteraceae]) plant communities by controlling flammable nonnative annual weeds, not harming desirable native plants, and possibly assisting in the establishment of seeded fire-resistant plant materials.
