New SCN calculator estimates economic yield loss

A new online resource from the SCN Coalition uses data collected from Iowa State University (ISU) research to estimate the cost of yield reductions from soybean cyst nematode (SCN) in individual fields.

The SCN Profit Checker is available at scnprofitchecker.com and allows users to provide specific information about SCN-infested fields to gauge the possible economic cost of yield loss caused by the nematode.

The tool is based on data from more than 35,000 ISU SCN-resistant soybean variety trial research plots in 180 studies conducted from 2001-2020 throughout all nine crop-reporting districts in Iowa.

There was a wide range of SCN population densities in the plots, from very low to very high, and the experiments were conducted in locations that had...
