Abstract

Band applications of residual preemergence herbicides were equal to timely shallow cultivations for the control of annual weeds in corn, and were superior when wet weather delayed or interfered with early shallow cultivations. The average corn yield reduction of 7.4 bushels per acre from weed competition observed over a 13 year period, suggested that under average conditions the net cost of herbicide treatment would be less than the value of corn lost through failure to control weeds.
