Consider these three guidelines to ensure maximum weed control with Liberty in LibertyLink corn and soybean and view a time-lapse video demonstrating how quickly waterhemp regrows when treatment occurs after the optimal weed height of 4 inches or less.
Researchers tested three preemergence herbicide strategies in Roundup-Ready Corn to identify how their application affected the critical period of weed control — the period when weed control is essential to avoid yield loss.
Results from a 2017 weed management trial on glyphosate-resistant ragweed indicated two applications were often more efficient and cost effective than either three applications or one application of herbicide.
Nebraska university weed scientists conducted research in 2017 to identify the effect of preplant tillage on weed emergence in an effort to develop an integrated weed management plan to control glyphosate-resistant weeds. Here's what they found.
Horseweed (marestail, Conyza canadensis L.) is a unique weed species that can emerge in both fall and spring. In Nebraska, unlike the eastern Corn Belt, horseweed populations predominantly emerge in fall as a winter annual.
