Samples to check for SCN can be taken anytime during the year, but soil samples taken following harvest provide the best population density estimates.

Soybean Cyst Nematode - Scouting

First, determine your purpose for scouting for SCN.

This will help determine your best strategy: whether to check soybean roots, or to collect a soil sample — and when and how to collect the sample.

Are you scouting...

• to check  if SCN is present in a field before planting next year's soybean crop? Collect a soil sample»
• to determine if your SCN management program has been successful in keeping SCN population densities in check? Collect a soil sample»
• to determine if SCN was responsible for poor soybean yields? Collect a soil sample»
• to look for SCN in stunted or yellow soybeans observed in mid-season, OR
  in fields that are apparantly healthy, but have not yet been checked for SCN? Examine soybean roots»
