Abstract

Currently, Iowa farmers have no convenient method for reliably determining weed pressures in a field. It is difficult to establish an efficient weed management program without a realistic estimate of weed pressure. As a result, many farmers may apply more herbicides than are necessary to achieve adequate weed control. This practice may result in excessive production costs or degradation of the environment due to erosion or overuse of herbicides.
