This article originally appeared in the AGVISE Laboratories Winter 2022 Newsletter This is the third year of our soybean cyst nematode (SCN) resistance project. Each year, we have flagged spots in soybean fields and collected paired SCN soil samples in June and September. If the SCN egg count increases through summer and into fall, we […]
