Sudden Death Syndrome (SDS) and Soybean Cyst Nematode (SCN)

Images and phone calls related to Sudden Death Syndrome (SDS) have been coming into our offices over the last 7-10 days. Many of the suspect fields are being positively diagnosed with SDS. Paul Esker and I walked a field this morning with Matt Hanson, Doge County Crops and Soils Agent, and found a field that was most likely SDS. The symptomology in this field was odd in that it was appearing in small rings across the field and only in certain varieties. Recent literature however has suggested a positive relationship between soybean cyst nematode and SDS. Therefore we would recommend that anyone finding SDS also check for SCN. Remember the WI Soybean Marketing Board provides free testing for SCN for Wisconsin soybean growers. (For more information on this test please click here).
