SCN – Soybean Cyst Nematode analysis is something to really consider with respect to managing your soil.
Greg Tylka of the Iowa State University Department of Plant Pathology and Microbiology said one of the main reasons this happened is because of the area soils. “North Central Iowa is the sweet spot for SCN,” Tylka said at a farm field day in Kanawha. “The reason for that is because nematodes love the high PH in soils.” Source: How to manage soybean cyst nematode, September 17, 2014
Two ways are available to scout for SCN and neither involves “driving in an air conditioned pickup at 70 miles per hour,” GregTylka quipped.Farmers can dig roots and look for little white females in late June, July and August. SCN females are small, about the size of a period at the end of a sentence. Soil samples can be pulled after harvest. Using a soil probe, pull 15 to 20 soil cores per sampling, mix them in a bucket and send them to a private soil-testing laboratory that does SCN testing or to ISU’s Plant and Insect Diagnostic Clinic.

The most accurate way of determining whether SCN is present in a field is to have the soil tested in a nematology lab for the presence of SCN eggs. Sampling efficiency and laboratory cyst extraction are not 100 percent effective, however, and a significant number of SCN eggs need to be present in the soil for lab detection.
