Soybean Cyst Nematode Best Management Practices

  • Plant SCN-resistant soybean varieties
  • Rotate host and non-host plants
  • Keep plants healthy
    • Maintain soil fertility
    • Prevent/reduce pest pressure (weed, insect, disease)
  • Sanitation
Non-host crop plants* Host crop plants*
  • Alfalfa
  • Barley
  • Canola
  • Clover (red, white, ladino)
  • Corn
  • Oats
  • Rye
  • Sorghum
  • Wheat
  • Soybeans
  • Beans (green, snap, mung, bush)
  • Adzuki beans
  • Birdsfoot trefoil
  • Cowpeas
  • Clover (alsike, crimson, scarlet)
  • Garden peas
  • Lespedeza
  • Sweet clover
  • White lupines
  • Vetch (common, hairy)

* Some plants may be considered “poor” hosts and thus be found listed as host or non-host according to various sources.

 

Midwest Rotation Example

Crop Rotation Strategy

* Source of Year 1 and Year 3 SCN resistance should be from different source lines. If this is not possible, the minimum strategy is different
soybean varieties.
