Staying on top of all the latest ag technology, field data and research can be overwhelming. That’s why the Soybean Research & Information Initiative, formerly the Plant Health Initiative, continually provides you with access to expert information and news about soybean pests, diseases, and agronomics. The aim of this check off-funded website is to communicate the on-going progress and current understanding coming from your active and wide-ranging U.S. soybean research programs.

Benchmarking Soybean Production Systems in the North-Central USA
by Patricio Grassini, Cropping System Extension Specialist, University of Nebraska, and Shawn Conley, Soybean and Wheat Extension Specialist, University of Wisconsin

From 2010-2014, the average soybean yield in the north-central region was 43 bushels/acre. Yet some producers can consistently attain soybean yields near or greater than 80 bushels/acre. In the first few months of a 3-year project, we have collected data from over 3,000 soybean fields in the region and are identifying key management factors that can be used by individual producers to increase soybean yield closer to the yield potential of their farms.   Read more...

Soybean Entomology in the North Central Region: Management and Outreach for New and Existing Pests
by Kelley Tilmon, Field Crop Entomologist, Ohio State University

Our interdisciplinary entomology and plant breeding team, comprised of 18 research and extension scientists in 12 states, has a long history of working together to solve insect problems of regional importance in soybean. This summer we are sampling for new and emerging pests such as stink bugs and thrips.

In our continuing work on soybean aphid, we have begun to backcross the aphid resistance genes Rag4 and Rag6 into the same MG group I and II backgrounds that we used to backcross Rag1, Rag2, and Rag3. The 2015 fall trap data predicted a small 2016 spring egg hatch and fewer aphids this summer.   Read more...

Breeding to Improve Resistance to Sudden Death Syndrome (SDS) as a Means to Protect Yield
By Brian Diers, Soybean Breeder, University of Illinois

Planting the most resistant varieties available is the foundation of an SDS management program. Our work on genetic resistance to SDS has made good progress towards the goal of providing growers with soybean varieties with increasing SDS resistance.

At least 17 varieties and germplasm lines have been released. Mapped and confirmed genes are now being integrated into breeding programs through the use of marker-assisted selection, which should continue to increase the pace of developing SDS-resistant varieties.   Read more...

Predicting the Risk of Sclerotinia Stem Rot of Soybean
by Mehdi Kabbage and Damon Smith, Soybean Plant Pathologists, University of Wisconsin.
Sclerotinia stem rot (SSR), also called white mold, is a sporadic but yield-limiting disease in the north-central region. Specific weather conditions must be present at the time of soybean flowering -- if they are absent, then SSR is unlikely to occur. One of the objectives in our current work on Sclerotinia stem rot is to more clearly define the effect of weather and application timing on the efficacy of fungicides.   Read more...

New Video on Soybean Seedling Blights
Kiersten Wise, Plant Pathologist, Purdue University and Loren Giesler, Plant Pathologist, University of Nebraska-Lincoln
In this video, we show how to recognize seedling diseases in the field, and how to collect a sample to confirm the field diagnosis. We have also updated the publication Fungicide Efficacy for Control of Soybean Seedling Disease as of April 2016.   Read more...

Micronutrients for Soybean Production
by Antonio Mallarino, Soybean Agronomist, Iowa State University
Over the past year, with funding from the North Central Soybean Research Program, a team of agronomists from five north-central states have collected and analyzed all of the published and unpublished university field response-based information about micronutrients and soybeans in the region. We plan to summarize this information in a comprehensive publication to be distributed widely in the fall of 2016.   Read more...
