The SCN Coalition is a partnership of public, private and checkoff organizations formed to increase the number of growers who are actively managing soybean cyst nematodes (SCN). Partners include university scientists and extension personnel from 28 states and Ontario, Canada, plus state, regional and national soybean checkoff organizations and nine corporations. Managing SCN is more than planting SCN-resistant soybean varieties. The Coalition encourages farmers to test their fields to know the SCN population densities (numbers) in the soil to monitor and better manage this yield-robbing pest.
