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

Thu - October 12, 2017
by Shawn Conley, University of Wisconsin

Understanding and being able to correctly identify the growth stages of soybean is important for making sound agronomic management decisions. This guide describes the growth stages starting with germination, progressing through the vegetative stages (V) and concluding with the reproductive stages (R).   MORE

As an introduced pest, knowledge of the distribution of Heterodera glycines, the soybean cyst nematode, can be helpful in identifying areas where scouting and management efforts should be focused.

Such information is especially important for SCN because yield-reducing infestations can occur without obvious above-ground symptoms.   MORE

A new resource is available for farmers and crop advisors in the North Central region regarding micronutrient use in soybean production.

It is the first regional publication with a thorough discussion of micronutrient needs for soybean, based on information compiled from response-based field studies throughout the North Central region.

It also includes a thorough discussion on the value of soil and plant tissue analyses to determine micronutrient needs.  MORE

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
