Frequency grid-a simple tool for measuring grassland establishment
Simple, reliable tools are needed by land managers to quantify establishment success when seeding or re-seeding pastures or rangeland. A frequency grid was designed to measure seedling or plant… Expand
Invited Synthesis Paper: Principles and practices for managing rangeland invasive plants
Invasive plants reduce the capacity of ecosystems to provide goods and services required by society, alter ecological processes, and can displace desirable species. They can reduce wildlife habitat… Expand
Imidazolinone herbicides improve restoration of Great Plains grasslands
Evidence is provided that the imidazolinone herbicides can be important components of integrated weed management strategies designed to reverse deterioration of grasslands by reestablishing native species, improving grassland productivity, and decreasing the prevalence of exotic weeds. Expand
Herbicides for Establishing Switchgrass in the Central and Northern Great Plains
Quinclorac, which provides effective control of grassy weeds, and herbicides such as atrazine which provide good broadleaf weed control are an excellent herbicide combination for establishing switchgrass for biomass production in the Great Plains and the Midwest. Expand
Native Wildflower Establishment withImidazolinone Herbicides
Based on these findings, imazethapyr and imazapic can reduce weed interference and improve the establishment of some native wildflowers in areas with high weed infestations. Expand
Rangeland Invasive Plant Management
Using an herbicides treatment in the year following a prescribed burn gave far better control of yellow starthistle compared with an herbicide treatment followed by prescribed burning, and could increase the communities' resistance to reinvasion by other invasive plants. Expand
DNA-based marker systems to determine genetic diversity of weedy species and their application to biocontrol.
DNA-based molecular markers may be used to increase the under- standing of these factors and contribute to the success of biological weed control by helping to target the most vulnerable species and provide more realistic expectations of the potential for success given available resources. Expand
Canada Thistle (Cirsium Arvense) Control with Aminopyralid in Range, Pasture, and Noncrop Areas
Aminopyralid provided effective Canada thistle control at lower use rates than current commercial standards and might be useful in areas where herbicides such as picloram and clopyralids are not recommended for use. Expand
Influence of improvement practices on big blue-stem and idiangrass seed production in tallgrass prairies.
Tallgrass prairies provide a valuable source of diverse native plant germplasm. Seed harvested from native prairies can be used to revegetate highly erodible or marginal cropland and degraded… Expand
Adjuvant effects on imazethapyr, 2,4-D and picloram absorption by leafy spurge (Euphorbia esula)
Laboratory experiments were conducted to identify adjuvants that improve absorption of imazethapyr, 2,4-D amine, and picloram by leafy spurge. Adjuvants (0.25% v/v) included crop oil concentrate… Expand
