Agronomists and weed scientists recommend using more soil residual herbicides at full use rates to take weed stress off non-residual postemergence herbicides by introducing multiple, effective modes of action, different chemistries and controlling weeds for longer periods of time before they emerge. This strategy is called the Overlap System. </p></div> <div class="og_rss_groups"></div><p><a href="http://cornandsoybeandigest.com/fmc/use-overlap-system-more-complete-weed-control" target="_blank">read more</a></p> http://cornandsoybeandigest.com/fmc/use-overlap-system-more-complete-weed-control#comments FMC Crop Chemicals Herbicides Weeds Tue, 17 Mar 2015 14:09:00 +0000 96451 at http://cornandsoybeandigest.com Weed resistance management tips http://cornandsoybeandigest.com/crop-chemicals/weed-resistance-management-tips <div class="node-body video-body"><p>Managing editor Susan Winsor spoke with Ford Baldwin about weed resistance problems and how growers can manage the resistance issues that keep moving farther north.
