Introducing Soil Sense: Field Check. We find the right expert to answer YOUR questions about anything related to farming, agronomy, and soil health. We invite you to participate at www.NDFieldCheck.com.
Today’s question comes from Jason Hanson of Rock & Roll Agronomy:
“There’s going to be Prevented Plant, and now with the uncertainty of dicamba registrations moving forward, even though North Dakota is a 24(c): How does winter cereal rye help with controlling kochia as a potential other option?”
To answer this excellent question that Jason has been getting, we enlisted the help of North Dakota State University Extension Weed Specialist Dr. Joe Ikley. Joe is based in Fargo and is responsible for all crops in the state except potatoes and sugar beets. He conducts weed control research primarily in corn, soybeans, and dry beans.
Listen to this short Field Check episode for Dr. Ikley’s full answer, but here is one quote you may find helpful:
“When we look at an overwintering cover crop like rye, we get our best weed control on winter annual weeds, but of course kochia is a summer annual weed…. (rye) does not reduce the number of plants that we are going to have to spray, but it does buy us more time to get a timely herbicide application on there.”
