2017 a banner year for IDC in parts of Upper Midwest

A soil scientist calls 2017 a banner year for iron deficiency chlorosis (IDC) in parts of the Upper Midwest.

 

Daniel Kaiser with the University of Minnesota says a cool, wet May was a major contributor as IDC has been prevalent in soybean fields across western Minnesota and the Red River Valley.

“Just talking to some growers this week in areas of Yellow Medicine County (Minnesota), they’ve had a couple good years where they hadn’t had any (IDC).  And this is probably one of the worst years they’ve seen for a while.”

He tells Brownfield that’s particularly true in early-planted soybeans.

“In one of our field studies we were looking at different treatments for IDC, the grower planted before we planted.  He was in right before a stretch of rain in May and his stuff looks far more yellow.  So just looking at what we had, I think that cool, wet conditions really compounded some of our issues.”

 

Kaiser says the best option for managing iron deficiency chlorosis is with an in-furrow application of a product like SoyGreen.

He adds if symptoms are already present, it’s probably too late for treatment.
