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»

What about HG tests?
Much has been learned in the past several decades about development of SCN on resistant soybean varieties. It is apparent from this new knowledge that a change in how we describe the abilities of a SCN population to reproduce on resistant soybean varieties is warranted.
A new system, called the HG Type test (HG for Heterodera glycines, the scientific name for soybean cyst nematode) has been developed and adopted by agronomists, plant pathologists, and soybean breeders. Read more about the new SCN HG Type test».
