What is going on with Soybeans

We have been hearing lots of report of Sudden Death Syndrome (SDS) in soybeans.  On Saturday August 23, on a trip to Farina, we saw some variety plots near St. Peter.  3 of those plots were turning yellow. I thought it was probably not SDS.  Now I am not so sure.  First I heard a rumor that two fields were harvested locally because of SDS.  Rumor is that yields were in the mid 30's.  Then on a trip to Pearl on Friday, there were a number of fields that had leaves turning.  I was looking for classic SDS symptoms with patchy dying back. In many cases I saw whole fields that seemed to be turning.  The top picture below shows most of the field turning.  It could be just variety, because soybeans in the background are still green.  The two photos below show classic SDS symptoms.  Carl Bradley wrote on the late season diseases in soybeans.  I was not able to go into the fields to do a definitive diagnosis.  Whether the beans are early of diseased, they are not getting the benefit of a full growing season.

Another observation is that I am nos seeing problems in double crop soybeans. 
SDS or maturing beans?

Just before I found your latest post in Feed Reader (we follow your blog there), I posted this from Delaware. I pass it along FYI.
