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.

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...

New Reference Guide Helps Producers Assess If and When to Use Neonicotinoid Seed Treatments
by Christian Krupke, Soybean Entomologist, Purdue University
Recent field studies conclude that yield benefits attributed to neonicotinoid seed treatments are often inconsistent or absent. These results and more are outlined a new resource guide for soybean producers.

Exploiting Bio-Control Agents to Manage Seedling Diseases of Soybean
by Ahmad Fakhoury, Plant Pathologist, Southern Illinois University
We tested 58 potential biological control organisms isolated from soybean fields against seven soybean fungal pathogens and found several organisms that restrict the growth of Fusarium virguliforme , which causes sudden death syndrome, Fusarium graminearum, a seed decay and damping-off pathogen, and Macrophomina phaseolina, the causal agent of charcoal rot.   Read more...
