    Herbicide resistance (HR) in weeds is a threat to the sustainability and profitability of the Northern Great Plains (NGP) agriculture. Growers and ranchers need awareness and training on mitigating HR issues on their farm through adoption of Best Management Practices (BMPs). The main goal of this project was to enhance the knowledge of agricultural professionals on HR weed evolution, dynamics, socio-economic impacts, and mitigation through incorporation of BMPs. This educational project will take place in 3 different phases. During 2016 and 2017, we completed Phase 1 (Course Development) and Phase 2 (Instruction) of this regional project. The major accomplishments/milestones have been provided in the report. Phase 3 (Evaluation) was initiated in the second year (2017) and was accomplished by March 2018 to evaluate the acquired change in knowledge, outreach to growers and ranchers, and long-term gains on the awareness of HR and BMPs.

    Project objectives:

    Objective 1: Course Development (Completed)

    1. Major activities: Photographs and details on major herbicide-resistant (HR) weeds of NGP, HR weed infestations on farm fields, frequency and distribution maps at the State/County level, and related research results on HR weed surveys will be compiled into extension bulletin, fact sheets, oral/poster presentations
    2. Sustainable BMPs for managing HR kochia through past and current research projects at the MSU Southern Ag Research Center and other published work in the region will be utilized for the development of fact sheets and oral and poster presentations
    3. Printing these educational materials and development of web-based training modules

    Objective 2: Instruction (Completed)

    1. Major activities: Classroom instruction, Field days, and workshops for Ag Professionals
    2. CCA seminars, on-site demonstrations, surveys
    3. Field instruction for Ag. Professionals

    Objective 3: Evaluation (Completed)

    1. Main activities: Interactive Workshop
    2. Follow-up  surveys
    3. Evaluation of knowledge gained by Ag Professionals
