"In just the past three years, soybean cyst nematode (SCN) has spread to 55 new U.S. counties in 11 states," says Dr. Greg Tylka, Iowa State University (ISU) nematologist and co-leader of The SCN Coalition. "SCN is now widespread in New York," says Dr. Gary Bergstrom. "Soybean growers are fortunate that in most fields where SCN has been detected, population densities are low, although it's concerning that a few counties had higher numbers." Growers are asking questions about SCN-resistant varieties, nematicide seed treatments, and soil testing for SCN. In 2020, researchers concluded that from 1996 to 2016, SCN caused yield losses of $32 billion dollars; averaging $1.5 billion annually. Research and sampling will be continued into the 2021 growing season in SWNY and throughout the state.
