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.

RESEARCH HIGHLIGHTS

by Patricio Grassini, Cropping System Extension Specialist, University of Nebraska, and Shawn Conley, Soybean and Wheat Extension Specialist, University of Wisconsin

In the latest issue of the journal Agricultural & Forest Meteorology, we report on a novel approach to assess yield gaps (the difference between maximum yield potential and measured producer yields) in soybean in the north-central region of the U.S.   MORE

The persistent hot weather in many areas of the country this growing season may be conducive to the development of charcoal rot disease in soybean.

Farmers, agronomists, crop consultants and specialists are encouraged to scout for this particular disease now. Although charcoal rot is most severe in years and areas experiencing hot, dry weather, this disease can also cause losses when ample moisture is present, making it a hidden threat to yield.   MORE

The soybean aphid can be controlled by Rag genes (Resistance to Aphis glycine) which have been introgressed into soybean lines adapted to Midwestern growing conditions.

Our soybean breeding program continues to develop and release soybean varieties with different combinations of Rag genes conferring aphid resistance. The University of Illinois has commercialized four soybean varieties with Rag2, one variety with Rag1, and one variety with Rag1 and Rag2 combined.   MORE

We conducted a review of what is known about soybean aphid — in particular, the potential effects on yield and cost-effective management for this pest.

We found that although crop and input prices have changed since the establishment of an economic threshold (ET) of 250 aphids per plant, no consistent economic gain can be found with a reduced ET for soybean aphid. This is because the ET is already set well below the aphid population level that can cause measurable yield loss.  MORE
