Time of Weed Control

Authors: David Rueber (Iowa State University) , Robert G. Hartzler (Iowa State University)

Abstract

Roundup Ready (RR) crops provide growers greater flexibility in weed management due to the ability of glyphosate to control larger weeds than other herbicides. Although this is advantageous, it can lead to yield losses if the glyphosate application is delayed too long. Research was conducted to determine the role of preemergence herbicides(PRE) and postemergence glyphosate applications(POST) in protecting crop yields in Roundup Ready corn and soybean.
