As the 2026 soybean harvest wraps up across Indiana, growers have an excellent opportunity to assess one of the most damaging and often overlooked threats to soybean production: soybean cyst nematode (SCN, Heterodera glycines). SCN is the leading yield-limiting pathogen of soybean in the United States, causing an estimated $1.5 billion in annual losses. One of the biggest challenges in managing SCN is that infected soybean plants may appear healthy even when significant yield losses are occurring. If your corn yields have been steadily increasing while soybean yields remain stagnant, SCN could be one of the contributing factors. Even if you have never observed symptoms of SCN in your fields, that does not mean the nematode is absent. Fall soil sampling is a simple and effective way to determine whether SCN is present and assess its population density. Why Should Indiana Growers Be Concerned About SCN? SCN is widespread in[Read More…]

Support from the SCN Coalition and National Soybean Board will continue to provide FREE soybean cyst nematode (SCN) soil testing this spring to Indiana growers. If you have trouble fields that you have not had a recent SCN test please consider sending in a soil sample to test for SCN. This program will support one sample per Indiana farm to be submitted to the SCN Diagnostics at the University of Missouri. Please print off a form here https://ag.purdue.edu/btny/ppdl/Documents/PPDL-3-W%20SCN%20Survey-MO.pdf to include with your soil sample. Additional samples will cost $25/each. Pack the samples in a box and cushion the samples with packing material so the bags don’t break open during shipping.
