Abstract

Populations of weeds capable of affecting crop yields are present in every field during every year. Perhaps it is the ubiquitous nature of weeds that leads to the complacency in their management across Iowa and the Midwest. A survey of Wisconsin corn and soybean fields found that weeds were managed in a way that resulted in yield losses in more than 10% of surveyed fields, with an average yield loss of slightly less than 10%.
