Brief Project Summary:

The specific objective of this project is to encourage statewide monitoring for the soybean cyst nematode, by providing funding to offer this service to soybean farmers across NY. The soybean cyst nematode (SCN) is considered the number one pest of soybeans nationally and globally, causing an estimated 109 million bushels of yield loss in the U.S. in 2017.
Extensive collaborative sampling for this pest from 2014-2017, partially supported by both the NY Corn and Soybean Growers Association (NYCSGA) and Northern NY Agricultural Development Program (NNYADP), was coordinated by Cornell University and Cornell Cooperative Extension programs. Over the four years of the soybean disease surveys,...

In 2021, 68 soybean fields were tested for soybean cyst nematode (SCN), of which 13 fields tested positive. This is a decrease from last year's rate of positive samples, but it's unrealistic to expect that this represents a decline in SCN overall. After covering most of the state in prior years, we expanded our search into mostly all previously un-sampled soybean fields, and into two previously un-sampled counties, both of which yielded positive samples. Together with fields sampled for a companion study of dry bean fields, SCN was found in an additional 4 counties this year. Soybean cyst nematode has now been detected in 34 of the 45 upstate counties sampled since 2016. Results from this year's study and current management recommendations were shared at 14 extension meetings in NYS, Colorado, and virtually via the University of Delaware. A forthcoming extension article will share 2021's results and promote the project for 2022.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
