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.

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.

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.

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.

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.

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.
