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.

As part of an on-going regional research project called Identification and Biology of Seedling Pathogens of Soybean, funded by the North Central Soybean Research Program and the United Soybean Board, we answer frequently-asked questions about soybean emergence and seed treatments in this new publication.  MORE

Although SCN-resistant soybean varieties are available to minimize yield loss to soybean cyst nematode (SCN), over 90% of the varieties available to growers in the north-central United States have the soybean line PI 88788 as the genetic source of resistance. The effectiveness of PI 88788 resistance has decreased over time as nematodes have adapted to this type of resistance. Producers are faced with limited options for rotation once virulent SCN populations develop in their fields.

To provide farmers with effective and durable rotation schemes, we have identified seven genes from five soybean lines, including wild soybean (Glycine soja), and are using them to develop lines with new combinations of SCN resistance genes.  MORE

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.  MORE

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.  MORE
