Summary of Methods: The purpose of the study was to determine the feasibility of using imazapic and seeding to control cheatgrass and annual forbs to create fuelbreaks. The study was located in a Wyoming big sagebrush plant community near Carson City, Nevada. Four treatments (imazapic applied at 105 g ai/ha, seeding of site, imazapic and seeding together and control) were applied to plots established within an existing fuel break established the year before. Plots were evaluated one and two years after treatment.
Article Summary / Main Points: None of the seeded species were found in the plots, with the exception of a small number of 'Immigrant' forage kochia plants, due to drought. A single application of imazapic significantly reduced cheatgrass production for 2 years. Tall tumble mustard and redstem filaree were controlled with a single application of imazapic for one year. Wyoming big sagebrush, rubber rabbitbrush, and forage kochia were not negatively affected. Bailey's buckwheat and skeletonweed were improved and unaffected after the second year.
