Accomplishments
Short-term outcomes: Continued collaborative efforts of the NCERA 137 multi-state working group are advancing recommendations for managing soybean diseases.
Outputs: Within participating states, information was shared through multiple platforms including winter meetings, research publications, extension publications, social media, and other web platforms. Coordinated efforts of this multi-state project enabled data exchange for regional and national recommendations including:
- Soybean Disease Loss Estimates from the United States and Ontario, Canada – 2022. Crop Protection Network. CPN 1018-22. doi.org/10.31274/cpn-20230421-1
- Crop Protection Network recommendations for Fungicide Efficacy for Control of Soybean Foliar Diseases. CPN 1019. doi.org/10.31274/cpn-20190620-014.
- Crop Protection Network recommendations for Fungicide Efficacy for Control of Soybean Seedling Diseases. CPN 1020. doi.org/10.31274/cpn-20190620-015
Impacts
- Impacts 1. Objective 1: Foster collaborative research and information exchange on new and emerging soybean diseases among scientists in the North Central Region including soybean breeders and entomologists that will lead to improved disease screening protocols, additional sources of disease resistance genes and ultimately, improved host plant resistance. Project participants work on diverse systems including Xylaria necrophora, pathotype diversity of P. sojae, Cadophora gregata, Sclerotinia sclerotiorum, Heterodera glycines, Calonectria ilicicola among others. Four varieties were released with resistance to Sclerotinia sclerotiorum in 2022, which will be released to farmers in 2024. 2. Objective 2. Compare findings on the impacts of changing production practices such as earlier planting dates, new sources of host plant resistance, increased use of fungicide seed treatments and foliar fungicides, and other new or improved crop production technologies on soybean diseases that could be adopted for other production areas in the region. Project participants are evaluating several seed-applied nematicides to the southern root-knot nematode, seed treatments for management of sudden death syndrome and soybean cyst nematode, facilitating submission of soil samples for SCN testing in individual states, evaluate the sensitivity of Cercospora sojina and Diaporthe collected from multiple U.S. states to DMI, MBC, and SDHI fungicides, among others. A consensus fungicide efficacy data is prepared by the NCERA 137 group members at individual institutions in concert with Crop Protection Network to build the foundation for fungicide guidelines published annually for farmers. 3. Objective 3. Compare data from studies of the ecology and epidemiology of soybean diseases important in the North Central Region. Project participants are coordinating efforts to conduct epidemiology trials to understand Cercospora-associated diseases in soybean. This includes spore trapping efforts and disease rating efforts among numerous states who participate in coordinated foliar fungicide trials. In addition to Cercospora, the project participants are also involved in assessing yield losses associated with soybean diseases in the NC region. As an example, red crown rot was added to the list of soybean diseases as this disease is being found in more states. Yield loss data is compiled to track disease impacts annually by region, nationally and across years. 4. Objective 4. Improve knowledge transfer about soybean diseases and their management in the North Central Region to researchers, Extension faculty, producers and the agribusiness community through the use of web sites, podcasts, social media (Twitter and Facebook) and other new technologies as they are developed. Knowledge transfer is being conducted via webinars for CPN, I See Dead Plants podcast, A Penny for your thought podcast, first MU youth scouting event for students from 6th to 12th grade, extension meetings, trade shows, field days, webinars, newsletters, podcasts, blog posts, newspaper articles, radio spots, YouTube videos, program webpages, public media interviews, ag media (DTN Progressive Farmer, MoSoy, AgWeek, etc.), leveraged partner media (agrochemical companies), and twitter. Multi-state reports, including yield loss estimates and fungicide efficacy charts are housed with the Crop Protection Network. Many participants are also active in the SCN Coalition. 5. Objective 5. Continue to monitor and share information for any new or reemerging pathogens of soybean in the North Central Region and develop appropriate responses to their emergence as they occur. Participants work with extension agents, stakeholders, farmers, industry, university researchers, and respective diagnostic clinics to monitor for potential new of emerging and re-emerging diseases. Many states are supporting testing of soil for SCN, monitoring for red crown rot, taproot decline, Cercospora leaf blight, Diaporthe-associated diseases, soybean cyst nematode, soybean rust, and spread of fungicide resistant C. sojina. Milestones: In year 5 (10/1/22-9/30/23) of this 5-year project, collaborative research projects continue to advance understanding of soybean disease management options and providing management recommendations to farmers. Annually, the NCERA 137 participants support yield loss estimates associated with soybean diseases in individual states, which are used to develop the CPN disease loss calculator. This group also develops publications to report trends in regional and national disease development to inform evaluations of soybean germplasm and chemical product efficacy screening. Impacts: Diseases in soybean can greatly impact yield potential. To facilitate data driven management recommendations, NCERA 137 participants performed research to address regionally significant diseases, conducted fungicide efficacy trials, and supported disease forecasting efforts. Research results were shared through extension programming (field days, grower meetings, publications, newsletter, blogs, YouTube videos, radio. and social media) to maximize effectiveness of disease management strategies and improve grower productivity and profitability.
