Sudden Death Syndrome Hits Soybean Fields

August 24, 2016

Sudden death syndrome (SDS) is back again – unfortunately not surprising, given that this year’s early planting and wet, cool spring conditions in many parts of the Midwest were ideal for SDS to infect soybean roots.

The environment plays a strong role in whether SDS appears in any given year or area. The risk of SDS infection is greatest when significant moisture occurs early in the growing season followed by heavy mid-summer rains saturating the soil.

We’ve mentioned before that it’s important to proactively reduce the risk of SDS outbreaks. Additionally, utilizing SDS tolerant varieties and seed treatments with protection against SDS can help protect soybean yields.

  • NK® Soybeans have proven tolerance to soybean cyst nematode (SCN), SDS and other pests and diseases.
  • Clariva® Complete Beans seed treatment, a combination of separately registered products, provides effective, season-long protection against SCN. Clariva Complete Beans also reduces the damage from SCN-related diseases, such as SDS.
  • Mertect® 340-F fungicide seed treatment has shown consistent performance and yield protection under SDS pressure in four consecutive years of testing. Mertect 340-F also offers additional activity on seedborne diseases, such as Phomopsis. Mertect 340-F can be added to Clariva Complete Beans to expand the pest protection to SDS.

Planting SDS-resistant NK Soybeans treated with these seed treatments can help mitigate the risk of SDS and, ultimately, help farmers grow more soybeans.
