In parts of the Corn Belt, genetic resistance to soybean cyst nematode is being overcome by the pathogen. NDSU Extension Plant Pathologist Sam Markell says resistance in the plants aren’t working well. “In North Dakota, it’s not that significant yet. There are places where this is happening. I don’t know of many. The genetic resistance is holding up well. Over time, that may change. Right now, planting a resistant variety and rotating the variety is very important.” Farmers can soil sample for SCN at harvest.
