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.

In recent years stem canker and other diseases caused by the Diaporthe group of fungi have become increasingly problematic in the North Central region, with 2014 being an especially prevalent year. Stem canker epidemics can occur in wet springs, and with climate experts predicting a trend of wetter springs, this disease is considered an re-emerging problem in the region.   MORE

The USDA Soybean Germplasm Collection contains over 21,000 accessions (plant or seed samples) including wild relatives, landraces, and soybean cultivars from around the world. Domestication of soybean has resulted in a loss of genetic diversity, with landraces retaining only about 63% of the diversity found in the wild Glycine soja.   MORE

In soybean, the symbiotic nitrogen (N)-fixing bacteria provide the needed N to the plant; however, modern cultivars rely on N fertilizers to achieve their full yield potential. Therefore, the improvement of di-nitrogen fixation capacity is considered essential in soybean breeding and might be achieved through the evaluation of traits related to biological nitrogen fixation.  MORE

In the past year, we have selected four transgenic soybean lines that have shown consistent improved resistance to soybean cyst nematode (SCN). Two lines that target a specific nematode gene were able to reduce the number of SCN cysts by 50-60% and the number of SCN eggs by 55-70%, compared to the control. Two lines targeting a second gene were able to reduce both cyst and egg densities by 50 to 70% compared to the control.  MORE
