Accomplishments

ACCOMPLISHMENT 1: Extension Master Gardener: Planting Pollinator Habitat

The NDSU Extension Master Gardener (EMG) Program with NDSU Extension Entomology is concerned about loss of pollinator habitat and began an educational initiative to promote planting home pollinator gardens. EMGs designed and built public pollinator gardens in prominent locations in North Dakota. These gardens serve as teaching and demonstration gardens for other EMGs and county agents who hold workshops and give tours to educate the public on the importance of pollinators, which native and ornamental flowers to plant for continuous bloom, how to use pesticides safely, and how to promote nesting habitat for bees. With Michigan State University Extension, we developed 3 fact sheets to further educate the public about gardening for better pollinator health.

ACTIVITIES: The EMG Program designed and built 27 public pollinator gardens in 20 counties. Prominent locations include the International Peace Gardens (Dunseith), the Chahinkapa Zoo (Wahpeton), the Red River Zoo (Fargo), School for the Deaf (Devils Lake), Nueta Hidatsa Sahnish College Gardens (New Town), Hi-Line Prairie Gardens & Orchard (Valley City) and the Williston Research Extension Center. These gardens serve as teaching and demonstration gardens.

OUTPUTS: A packaged outreach program is available for use by EMGs and Extension agents and contains 4 Extension publications, a PowerPoint for adults, and a lesson plan for youth. Two NDSU fact sheets were created/revised:  Bee-utiflul Landscapes: Building a Pollinator Garden (H1811) and Butterfly Gardening in North Dakota (E1266). With MSU Extension, we developed 3 additional fact sheets:  Pollination in Vegetable Gardens and Backyard Fruits (H1898), Insects That Look Like Bees (E1914) and Rare and Endangered Pollinators (in preparation).

OUTCOMES: Through the Planting Pollinator Habitat project, the EMG Program has certified 103 pollinator gardens in 24 North Dakota counties totaling 305,947 sq ft. Also, the program has certified 14 gardens with large acreage in the surrounding states of Minnesota, South Dakota and Montana totaling 96 acres. We expect the total square footage of new pollinator gardens to continue to increase as a direct result of participants applying what they learn through this educational project.

FUTURE PLANS: We plan to continue this project in 2020-2021 using funding provided by our CPPM-EIP grant one year renewal.

ACCOMPLISHMENT 2: 2019 Bine and Dine Hop Webinar Series

With significant growth in craft brewing, growers in the North Central states have begun to produce hops, diversifying crops grown at their farms. The influx of new growers to this crop created a demand for information about growing hops and using IPM to manage pests and keep the crop healthy. Through the NC IPM Center, members led the effort to form and continue the Great Lakes Hop working group.

ACTIVITIES: Michigan State University Extension educators organized the 2019 Bine and Dine Hop Webinar Series to get information to growers and answer their questions. Six live webinars were offered at noon once a month April-September. Topics covered were when and how to do pest, agronomic and fertility management practices plus discussions of current conditions, upcoming management milestones and emerging pests.

SHORT TERM OUTCOMES: The webinars drew 282 attendees from 6 north central states, 8 additional states, 3 Canadian provinces and 2 other countries. User-reported impacts: 93% increased their hop knowledge, 56% Utilized MSU resources; 69% Adopted new management practices including IPM this season; 83% Adopt practices or tools to increase yield, improve quality, or decrease inputs; 98% Reported they would sign up for the webinars in 2020.

OUTPUT: Participants were referred to hops.msu.edu (Growing Hops in the Great Lakes Region) where resources are gathered for timely reference.

FUTURE PLANS: The second year of the series began April 6, 2020.

MILESTONES: This innovative program was shared at our annual meeting and has been leveraged and promoted through the NCIPM Center’s Great Lakes Hops working group. By successfully forming a working group, organizers are able to share activities and resources in multiple states and provinces.

ACCOMPLISHMENT 3: 2019 Regional Youth Crop Scouting Competition

With a continued increase in global demand for a diverse diet and food supply, knowledge of integrated pest management (IPM) is now more important than ever for the sustainability of the world’s natural resources devoted to farming. To satisfy the growing demands of careers in the IPM sector, universities need to both attract youth interested in IPM, as well as inspire those without interest. Iowa State University established a Youth Crop Scouting Competition in 2010, and it has since expanded throughout the North Central region, and beyond.

ACTIVITIES: Annual crop scouting competitions have taken place since 2010; as of 2019 five states (Iowa, Nebraska, Indiana, Minnesota, Kentucky) compete. Each year, the involved states’ land grant universities hosts a statewide competition, in order to send a representative team to the regional competition. Each year, the host of the regional competition changes. Events vary and include: plant staging, identifying diseases, assessing plant injury, problem solving and written assessments.

SHORT TERM OUTCOMES: Seven teams, consisting of 35 youth from the five states competed in Ames, Iowa in the 2019 Regional Youth Crop Scouting Competition.

OUTPUT: In 2019, the Regional Youth Crop Scouting Competition included 35 students from 7 teams from Iowa, Nebraska, Indiana, Minnesota, and Kentucky, each led by one coach.

FUTURE PLANS: To make it national with support from national regulators and companies.

MILESTONES: The 2019 Regional Crop Scouting Competition saw its first, non-North Central team from Kentucky.

Impacts

  1. IMPACT 1: Extension Master Gardener: Planting Pollinator Habitat ISSUE: Many honey bees and native bees continue to experience major population declines. Nationally, U.S. beekeepers lost 37.7% of their colonies during winter 2018-19. This is significant because their pollination services are required for food production. North Dakota also leads the nation in honey production. Native bees, such as bumble bees are facing major threats to their existence. In 2017, the rusty patched bumble bee was listed as endangered in the United States. The range of the rusty patched bumble bee used to extend into North Dakota. However, this bumble bee has not been detected in North Dakota since the 1990s. Some butterfly species, such as the monarch have also experienced steep population declines. ACTION: The Extension Master Gardener (EMG) Program with Extension Entomology began an educational initiative to promote planting home pollinator gardens. The EMG Program designed and built 27 public pollinator gardens in 20 counties, including the International Peace Gardens (Dunseith), the Chahinkapa Zoo (Wahpeton), the Red River Zoo (Fargo), School for the Deaf (Devils Lake), Nueta Hidatsa Sahnish College Gardens (New Town), Hi-Line Prairie Gardens & Orchard (Valley City) and the Williston Research Extension Center. Extension Master Gardeners and their agents hold workshops and give tours in the gardens to educate people on the importance of pollinators, which native and ornamental flowers to plant for continuous bloom, how to use pesticides safely, and how to promote nesting habitat for bees. OUTPUTS: A packaged outreach program is available for use by EMGs and Extension agents and contains 4 Extension publications, a PowerPoint for adults, and a lesson plan for youth. Two NDSU fact sheets were created/revised: Bee-utiflul Landscapes: Building a Pollinator Garden (H1811) and Butterfly Gardening in North Dakota (E1266). With Michigan State University Extension, we developed 3 additional fact sheets: Pollination in Vegetable Gardens and Backyard Fruits (H1898), Insects That Look Like Bees (E1914) and Rare and Endangered Pollinators (in preparation). IMPACT: Impacts of the Planting Pollinator Habitat project include: the EMG Program has certified 103 pollinator gardens in 24 North Dakota counties totaling 305,947 sq ft. Additionally, the program has certified 14 gardens with large acreage in the surrounding states of Minnesota, South Dakota, and Montana totaling 96 acres. IMPACT 2 from 2019 Bine and Dine Hop Webinar Series ISSUE: With tremendous growth in craft brewing, growers in Michigan and other states have begun to produce hops, diversifying crops grown at their farms. For example, according to The Hop Growers of America 2016 Statistical Packet, Michigan increased harvested acreage of hops 103% from 2015-2016. The influx of new growers to this crop created a demand for information about growing hops and using IPM to manage pests and keep the crop healthy. A webinar series is a convenient and effective means to deliver new information to growers in multiple locations and encourage their discussion. ACTION: Michigan State University Extension educators organized the 2019 Bine and Dine Hop Webinar Series to get information to growers and answer their questions. Six live webinars were offered at noon once a month April-September. Topics covered were when and how to do pest, agronomic and fertility management practices plus discussions of current conditions, upcoming management milestones and emerging pests. OUTPUT: Participants were referred to hops.msu.edu (Growing Hops in the Great Lakes Region) where resources are gathered for timely reference. IMPACT: The webinars drew 282 attendees from 6 north central states, 8 additional states, 3 Canadian provinces and 2 other countries. Responses to a participant survey show growth in knowledge, adoption of new practices, use of land grant resources and interest in continued learning. Specific user-reported impacts: 93% increased their hop knowledge, 56% Utilized MSU resources; 69% Adopted new management practices including IPM this season; 83% Adopt practices or tools to increase yield, improve quality, or decrease inputs; 98% Reported they would sign up for the webinars in 2020. This innovative program was shared at our annual meeting and has been leveraged and promoted through the NCIPM Center’s hops working group. IMPACT 3. 2019 Regional Youth Crop Scouting Competition ISSUE: IPM is an important crop production strategy, but the knowledge base of IPM and agronomic practices is at risk of dying out. It is imperative that new generations of individuals are educated in these practices to ensure continued food security, and maintain rural population and economies. It is important to engage with students from all socioeconomic levels and regions early to help them develop their knowledge and interest of IPM, and help them develop the communication, critical thinking, and observation skills they will need for successful careers in agriculture. ACTION: The Iowa State University IPM program and 4-H Youth program developed the Regional Youth Crop Scouting Competition in 2010, which has expanded to five states. The competition includes task ranging from corn growth staging, field scouting, insect identification, nutrient deficiency, plant diseases, soybean growth staging, and weed identification. In addition to hands on events in the field with agricultural professionals, a written assessment of knowledge was also conducted. OUTPUT & IMPACT: In 2019, the Regional Youth Crop Scouting Competition at 35 students from 7 teams from Iowa, Nebraska, Indiana, Minnesota, and Kentucky, each led by one coach. Responses to a participant surveys show the following: All coaches spent at least 16 hours of preparation with youth, and cited university resources as primary reference materials; viewed the competition as a positive experience that helped students learn foundational IPM concepts; and expressed a desire to participate in a larger, national competition. The majority of youth were 4-H participants; several expressed a greater interest in ag-related professions; recommended increasing time at stations, number of stations, and participation numbers. From the survey responses, we concluded that youth time with a community leader was beneficial to youth development. Coaches felt prepared for the competition. The competition was well put together and can be replicated among states. The competition taught youth important IPM tactics and developed skills for future success in an agricultural career, made students more aware of the myriad career paths within agriculture, and generated more favorable opinions of land-grant universities.
