There are hundreds of resistant soybean varieties available for use in managing the soybean cyst nematode (SCN), a serious yield-limiting pest of soybeans. SCN-resistant soybean varieties are not immune; they can allow up to 10 percent SCN reproduction. Allowing 10 percent or less reproduction means the soybean varieties are providing 90 percent control.
