Control of Volunteer Soybean in Corn

By Jeff Gunsolus
This week I have received several inquires about the presence and potential impact of volunteer soybean in corn and cost-effective control procedures.  The scenario of volunteer soybean in corn is a fairly recent phenomenon due to the wide-spread use of the glyphosate-resistant technology in corn and soybean.  As a result, to my knowledge, data on corn yield loss potential as a function of volunteer soybean density is not available.  However, I do know of one NDSU study conducted by Dr. Richard Zollinger that does evaluate several herbicide options to control volunteer soybean in corn. You can find a general summary titled Control of Volunteer Roundup Ready Crops at:
