SDS, white mold showing up in soybeans

Sudden death syndrome (SDS) and white mold could cause economic losses in soybean fields this year. SDS comes from toxins already in the field and can be influenced by weather, and white mold incidence may be increased due to weather conditions, says Carl Bradley, associate professor, University of Illinois. He also notes that plants infected with SDS can look like plants infected with brown stem rot.

The primary method of managing SDS is to choose the most resistant soybean varieties available.  Some evidence has shown that high soybean cyst nematode (SCN) egg populations may also increase the likelihood of severe SDS; therefore, managing SCN populations through resistant varieties and crop rotation may also reduce the risk of SDS.  Unfortunately, there currently are no fungicide products registered that are effective in managing SDS, 

Unfortunately, once white mold signs and symptoms are detected in the field, fungicide applications generally will be futile, as the damage has already been done.  Management of white mold was discussed in an earlier article of the Bulletin.
