Reduce SDS Risk in Your Fields


Every year, sudden death syndrome (SDS) poses a threat for scores of soybean farmers. Rather than giving in to yellowed and defoliated soybean plants mid-season, scout your fields early to minimize risk of the destructive disease.

To get ahead of SDS before it becomes an issue, keep the following in mind to protect your bottom line:

  • Avoid planting continuous soybean fields: Planting back-to-back soybeans – especially in fields with a history of SDS – can increase the severity of SDS. The University of Nebraska-Lincoln Extension advises a two-year rotation out of soybean production and maintaining good crop nutrition to reduce the risk of SDS.
  • Watch out for soybean cyst nematodes (SCN): SDS is often found in fields also infested with SCN. SCN feeding causes root damage and creates gateways for this pathogen to infect the plant, so take steps to protect varieties against SCN. 
  • Scout more if conditions are right for SDS: Caused by the soil-dwelling fungus Fusarium virguliforme, SDS flourishes in cool, moist conditions, putting early-planted soybeans at risk. If conditions are optimal for SDS, the University of Missouri Extension recommends scouting often for SCN, seedling blights and several foliar diseases, including frogeye leaf spot.

Though there are no in-season treatment options for SCN or SDS, Golden Harvest agronomists encourage you to take the necessary steps to control both of these pests before they become an issue.

Golden Harvest Soybean varieties offer top SDS ratings, with an average 1.4-point advantage for relative maturities. Be sure to talk with your Golden Harvest Seed Advisor to learn which varieties are best suited for your fields.
