Many continuous corn fields across Iowa have significant volunteer corn problems this spring. Unless this year’s corn possesses a herbicide trait not present in the prior corn crop, there are no selective control practices available, other than cultivation. The lack of control options reinforces the value of adjusting combines to minimize harvest losses.
