Soybean cyst nematode (SCN) is a major problem in soybean fields throughout eastern and central Kansas. As of January 1, 2020, SCN was identified in 59 Kansas counties that produce >85% of Kansas soybeans. It is important to monitor SCN levels regularly to determine if management strategies, such as variety resistance and crop rotation, have been successful.
Immediately following harvest is the best time to check fields for SCN and start planning for next season. Confirming the presence of SCN and determining population levels is the basis for a successful integrated management program.
To make that process easier, the K-State Plant Disease Diagnostic Lab is now offering free SCN testing for Kansas producers. This program is facilitated by a grant received from the SCN Coalition.
