If you had sds in soybeans sample for scn

As we work to complete harvest and put the finishing touches on the growing season, it is not too early to start thinking about crops. The soybean cyst nematode SCN is a widespread pest of soybeans in Iowa and the Midwest, and SCN reproduction was extremely high in the growing season. Many of the fields in which soybeans were grown in will be planted to soybeans again in Fall is a perfect time to collect soil samples to check fields for SCN and to determine the population density number of SCN in the fields, if it is present. If SCN is discovered at low or moderate population densities, SCN-resistant soybean varieties should be grown in to maximize soybean yields in the presence of the nematode.

Sudden Death Sydnrome Appearing in Soybeans

Cool wet soils in spring can lead to increased chances for sudden death syndrome SDS or brown stem rot BSR in soybeans. While foliar symptoms for both of these diseases won't appear until later this summer, initial infection occurs in the spring. Later in the summer rains or irrigation around flowering time flush a toxin, formed by the infection in the roots, up to the leaves, creating the foliar symptoms. If you've had problems with sudden death syndrome or brown stem rot in the past, you should be aware that cool, wet soil conditions are favorable for disease development in spring.

Sponsored: SCN and SDS: The Connection

The presence of soybean cyst nematode SCN in a field substantially increases your risk of developing sudden death syndrome SDS and reducing your soybean yield potential. Soybean cyst nematode infestations are generally observed in lighter soil classes where a soybean crop has been grown continuously without being rotated to nonhost crops. The presence of SCN can be difficult to diagnose before damage occurs. Positive identification of SCN requires submitting a soil sample for nematode analysis.
