According to research conducted in South Dakota, soybean yield loss was 8 to 9% when volunteer corn density was about one plant per ten square feet. Yield loss increased to 71% at volunteer corn densities of about one plant per square foot.
Small seed size, weak stalks, seed shattering and improperly adjusted combines all likely played a role in the excessive volunteer corn growth, says University of Kentucky Extension.
Researchers consistently found that Fusarium virguliforme on corn kernels at average harvest loss resulted in the most sudden death syndrome, says a University of Nebraska Extension Educator.
Emerged volunteer corn at this time of year is normally considered to be a good situation, since all the volunteer plants will winterkill, but if a killing frost does not occur soon, they could be an impediment to farmers who would like to sow wheat this fall.
