Soybeans bouncing back after struggles with IDC

The research director for Peterson Farms Seed says soybeans are bouncing back after some struggles with iron deficiency chlorosis (IDC).

Dennis Schultze tells Brownfield outside of a few severe areas, most beans in the Dakotas and western Minnesota are greening back up.

“And actually with the ideal weather conditions that we’ve had, plenty of rain and heat, that really helps those soybeans grow through the symptoms.”

Those symptoms typically appear around V3, about a month after emergence.  He says soybeans start to turn yellow from a lack of nutrients.

“And then as the plants keep on growing, get taller (and) have more of a root structure under them, then they’re able to pull enough iron out of the soil. It’s usually the end of June into the middle part of July when you’ll see the most severe symptoms.”

Schultze calls IDC more of a problem than soybean cyst nematode in the Red River Valley.  He says it can be managed with certain traits, wider row spacing coupled with heavier seeding rates, and with products like SoyGreen that are applied at planting.
