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.

The number of SCN-resistant soybean varieties available for soybean farmers has increased steadily since the early 1990s. Iowa State University publishes an updated list of SCN-resistant soybean varieties in maturity groups 0, 1, 2, and 3 annually to help farmers know their choices. Compilation of the list is supported by soybean checkoff funds from the Iowa Soybean Association.  MORE

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
