Sudden Death Syndrome was confirmed in Minnesota in 2002 and in North Dakota in 2018. By 2020, it was found as far north as Cavalier, North Dakota. BASF Seed Treatment Representative Tracy Hillenbrand says there are two phases to the disease. There is a root rot phase that is often confused with brown stem rot. “If you cut the plant open, you’ll see with SDS the pith is still tan and healthy looking while with brown stem rot it is mushy,” said Hillenbrand. “The plant will move from root rot phase to the foliar phase in late August and appear that the soybeans are turning and getting ripe.” A key indication of SDS is yellow spots on the leaves. As it progresses, the leaf will turn yellow with green veins. BASF’s ILEVO Seed Treatment protects soybeans from SDS and soybean cyst nematode.
