The SCN Coalition: Leveraging the Public-Private Partnership to Benefit Farmers
Dylan Mangel, University of Nebraska
Background
The SCN Coalition is a Public-Private Partnership (PPP) of soybean checkoff, private companies and universities. The mission of The SCN Coalition is to conduct an SCN resistance management and awareness campaign to educate growers and industry on the reality of soybean cyst nematode (SCN) resistance development, to slow the development of highly aggressive SCN populations, and to minimize increasing levels of yield loss. The North Central Soybean Research Program (NCSRP) provides foundational funding that has led to one of the largest and most effective PPPs ever developed to manage an agricultural pest. NCSRP’s funds allow for the communications and management of partner relations that extends the impact of The SCN Coalition work.
Below, we present updates on The SCN Coalition activities in three sections: Mission and Activities in FY2025, Outputs and Outcomes in FY2025 and Planning Beyond FY2025.
Mission and Activities in FY2025
To accomplish our mission, we aimed to increase active management of SCN and encourage growers to talk to their crop advisors about the four primary management actions (soil testing, rotation, resistance, seed treatments) so they could develop a strategy that best fits their farm. We have leveraged NCSRP funding from multiple sources; all funding is complementary and not codependent. Funding from the NCSRP supports the communication and partner relations of The SCN Coalition (it is central to everything The SCN Coalition does). Leveraged funding received from corporate private partners supports primarily national activities of The SCN Coalition. As examples, in FY2022, this included the “SCN Root Check” campaign sponsored by Valent, “Talking Todes Together with BASF” and media relations at the Farm Progress Show to showcase BASF’s SCN Action Month program. In FY2023, these included the development of the SCN Profit Checker Tool (funded by USB) and the first annual National Nematode Day (NND) held in early October and fully funded by private partners. In FY2024, these included ongoing support of National Nematode Day, an educational video project with Valent and expansion of SCN Profit Checker media relations and promotions (funded by USB). In FY2025 this included ongoing support of National Nematode Day and social media campaigns with Valent and Indigo Ag to promote active SCN management. Throughout, in-kind funding from private corporate partners (media, advertising, etc.) multiplied SCN Coalition messages. Some aforementioned projects were conducted or expanded upon in FY2025.
During March and April 2025, The SCN Coalition held virtual meetings with private partners to provide updates on its results and activities and discuss ways their direct and indirect funding can support the mission and activities of The SCN Coalition. Also, in spring, The SCN Coalition held virtual update sessions for our university colleagues to ensure coordination of activities and discuss ways to leverage Coalition strengths for local growers. An update to NCSRP leadership was made on March 1st 2025. Throughout the remainder of the project cycle, The SCN Coalition leveraged activities that included: ongoing engagement with agricultural media and social media, a press release announcing the results of the 2024 market research funded by USB, support of partner activities, and more.
Outputs and Outcomes in FY2025
Market Research Reveals Increased Adoption of Active SCN Management
During December 2024, we repeated the quantitative market research that took place in 2015 and 2020 to determine the effectiveness of messaging and programs conducted by The SCN Coalition. The 2024 study found (also see attachment):
• 27% said they were soil sampling for SCN, up from 18% in 2015.
• 56% said they were rotating sources of genetic SCN resistance, up from 39% in 2015.
• 27% identified Peking as a source of SCN resistance, up from 15% in 2015.
• 42% said they use a nematode-protectant seed treatment, up from 22% in 2015.
We believe the market research affirms significant impact of The SCN Coalition. Depending on the tool(s) farmers use, the 2024 research study showed between 9% and 20% more are actively managing SCN than in 2015. Surveyed farmers report capturing an additional 5.4 bu. per acre, adding $57.78 per acre to their bottom line based on an average price of soybeans of $10.70 during this 10-year period. But, research conducted by Dr. Tylka in Iowa demonstrates that depending on the level of SCN reproduction occurring on resistant soybean varieties in farmers’ fields, up to 23% more yield may have been recouped by actively managing SCN. That equates to tens of thousands of farmers, millions of acres and hundreds of millions of dollars in impact.

SCN featured on Farm4Profit podcast
In early March, Dylan Mangel and Horacio Lopez-Nicora were featured on the Farm4Profit podcast. The SCN Coalition coordinated for one of the central Iowa podcast hosts to have SCN soil sampling done. The hour-long podcast highlights why SCN is the No. 1 yield-grabbing pest, the tools available for active management, and a discussion on the soil test results. During the show, the soil test results were plugged into the SCN Profit Checker calculator. Podcast metrics:
• 16.5K weekly podcast downloads on average
• 500K social media followers
National Nematode Day
The SCN Coalition and sponsors BASF, Indigo Ag and Syngenta, gave their target audience a reason to pay attention and dedicate a day directed toward soybean cyst nematode (SCN) by declaring
October 6, 2025, National Nematode Day (NND). The SCN Coalition used NND to spread awareness about SCN across digital, social and ag media channels. A giveaway driving users to the NND webpage paired with innovative social media posts and digital ads helped spread awareness and drive engagement. NND was made possible by support leveraged from this NCSRP project, this included direct support from the three private corporate partners ($45,000) plus additional leveraged in-kind (media) support.

SCN Profit Checker key results
The USB-funded project strengthened The SCN Coalition’s presence in the soybean industry. Key results include:
• 18.5 million total media impressions garnered in the ag media.
• Articles about SCN Profit Checker appeared in Progressive Farmer, Farm Journal and The Furrow, and many regional publications.
• The calculator was highlighted on AgriTalk, Agriculture of America, U.S. Farm Report and AgDay TV, and many regional stations.
• 83,000-plus uses of the calculator online helped drive traffic to the Coalition’s website to view more information about active SCN management.
Awards
In April, The SCN Coalition received two first place “Best of NAMA” awards. The SCN Profit Checker won first place in Digital Tools and the campaign promoting the calculator placed first in Media Relations. NAMA is the largest agri-marketing association in the U.S.
Planning beyond FY2025
A complementary and non-codependent proposal (FY2026) was submitted to the United Soybean Board. The goal of the proposal, titled “Advancing innovative learning tools to combat parasitic nematodes in soybeans,” is to bring attention to the four nematode guides being created in FY25 with support from USB. Using the framework of The SCN Coalition, we proposed a multi-media campaign to broaden awareness and usage of the four guides.
During March 2025, SCN Coalition leadership held private-partner meetings with the leadership teams of Syngenta, Valent, Indigo Ag, BASF, and Pioneer. During the meetings we provide(d) an overview of research developments, results of Coalition programming and new resources that are available. We also present the results of the 2024 quantitative study, provide an update on checkoff-funded activities and discuss ways we can work together to further educational efforts. A total of $67,000 in funding from private partners was secured from private partners. During the meetings we also stressed the importance of their in-kind support, which is utilizing resources from The SCN Coalition, as well as our university experts.
Specifically, Syngenta indicated they would like help from SCN Coalition experts training their sales and support teams on the damage of parasitic nematodes as they anticipate the approval of their new nematode-protectant seed treatment. In addition, they requested experts be available at the 2025 Farm Progress Show to assist in farmer education and media interviews. As we maintain and strengthen relationships with our private partners, we are gaining industry insights, providing our feedback, and offering support in their educational efforts that in the long run help to improve the sustainability of the soybean industry.
The Soybean Cyst Nematode (SCN) Coalition is a partnership of universities, soybean checkoff programs, and agricultural companies working together to help farmers combat soybean cyst nematode, the most damaging pest of soybeans. The North Central Soybean Research Program provides core funding that supports the Coalition’s communication, outreach, and coordination among partners.
FY2025 Highlights
In 2025, the SCN Coalition continued to expand its impact by helping more farmers actively manage SCN by building awareness of soil testing, crop rotation, resistant soybean varieties, and seed treatments. Coalition activities were supported by NCSRP and leveraged with over $67,000 in direct private-sector funding and additional in-kind media support from industry partners including Syngenta, BASF, Valent, and Indigo Ag.
Documented Increases in Active SCN Management
A 2024 national market research survey compared farmer practices to baseline studies from 2015 and 2020 and found significant increases in active management:
• 27% of farmers now test their soil for SCN (up from 18% in 2015)
• 56% rotate SCN resistance sources (up from 39%)
• 27% can identify the Peking source of resistance (up from 15%)
• 42% use nematode-protectant seed treatments (up from 22%)
These changes, over the life of this project, represent a 9–20% increase in the number of farmers actively managing SCN. Surveyed farmers reported an average yield increase of 5.4 bushels per acre, adding a potential $57.78 per acre to their profits. Research suggests that even greater yield gains of up to 23% more could be achieved with continued SCN management.
National Communication Reach
The SCN Coalition maintained strong media momentum FY2025 with total project reach growing to:
• 1,281 online articles since launch, generating 45.6 million potential impressions
• 324 print articles, generating 27.9 million potential impressions
• Broadcast coverage exceeding 420 million potential impressions
This year’s website and social media also reached new heights:
• 115,942 new website visitors in FY2025, bringing total website traffic to 331,805 users since 2018
• 5.2 million social media impressions (Facebook, LinkedIn, and X combined)
• 365,862 Google Ad impressions with a 1.47% click-through rate
• 44,083 YouTube video impressions and 3,275 views across 10 new videos
National Nematode Day (October 6, 2025)
Supported by BASF, Indigo Ag, and Syngenta, National Nematode Day (NND) used online quizzes, sweepstakes, and videos to spark awareness about nematodes and SCN. Results included:
• 446 quiz entries and thousands of newsletter signups
• 255,000 digital ad impressions
• 3+ million social media impressions
• 1.4 million earned media impressions
• 80,000 webpage views leading up to and during NND
SCN Profit Checker Impact
The SCN Profit Checker calculator, which was developed with USB funding and promoted by the Coalition, helped more than 83,000 users estimate potential yield and profit losses from SCN. Media outreach for the tool generated 18.5 million additional impressions and major coverage in Progressive Farmer, Farm Journal, and The Furrow.
Looking Ahead
The SCN Coalition is building on this momentum through a new proposal, “Advancing Innovative Learning Tools to Combat Parasitic Nematodes in Soybeans,” submitted for FY2026. The Coalition will continue collaborating with public and private partners to produce educational tools, promote new nematode management guides, and extend the impact of SCN awareness across the soybean-growing region of North America, with the foundational goal of increasing grower profitability.
