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. Please visit often!

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Program, a team of agronomists from five north-central states have collected and analyzed all of the published and unpublished university field response-based information about micronutrients and soybeans in the region.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...

Identifying Novel Resistance to Seed and Seedling Rot Pathogens
by Jim Kurle, Soybean Plant Pathologist, University of Minnesota
Effective control of seed and seedling rots is becoming increasingly important to protect the value of seed, currently the largest single expense in soybean production. We have found that a range of partial resistance is present in a collection of soybean lines that could be easily incorporated into breeding lines adapted to short growing seasons.   Read more...

Strategies for Effective and Durable Management of Phytophthora
by Alison Robertson, Plant Pathologist, Iowa State University
Strategies such as quantitative resistance, also called partial resistance or tolerance, that put less selection pressure on the pathogen population should become a high priority in Phytophthora disease management and cultivar development.

Seedling Diseases of Soybean:  Characterization and Education
by Jason Bond, Plant Pathologist, Southern Illinois University
In this large, multi-state project, we've identified 15 soybean lines with partial resistance to seedling blight and root rot caused by Rhizoctonia solani. We established the baseline sensitivity of R. solani to fungicide active ingredients, which will allow us to monitor if shifts in fungicide sensitivity are occurring. Three new videos and several new publications on seedling disease diagnosis and management are now available as free downloads.

Developing an Integrated Management Plan for Soybean Sudden Death Syndrome (SDS)
by Daren Mueller, Soybean Plant Pathologist, Iowa State University
We found that ILeVO® fungicide applied as a seed treatment or in-furrow was effective at reducing SDS severity levels compared to control plots.

Several new print and online materials about SDS were developed as part of this project.

Major Findings on Soybean Vein Necrosis Virus:  Seed Transmission and Impact on Seed Quality
by Damon Smith, Plant Pathologist, University of Wisconsin
We have shown that SVNV can be transmitted in seed and systemically transmitted to the emerging seedlings at a rate of approximately 6%. It is the first virus of its type to be implicated in seed transmission. We also produced a new publication with close-up photos of SVN symptoms and seven look-alike diseases to help with diagnosis.   Read more...
