Resicore And Glyphosate Application Timings In Corn, R. Currie, P. Geier
Kansas Agricultural Experiment Station Research Reports
A study was initiated near Garden City, KS, in 2016, comparing the weed control of several herbicide treatments in irrigated corn. All treatments provided excellent, season-long control of kochia, Russian thistle, Palmer amaranth and green foxtail. Herbicide-treated corn yielded 219 to 235 bu/a, which was 86 to 102 bu/a more than nontreated corn; however, no differences in yield occurred among herbicide treatments.

Efficacy Of Preplant And Early Postemergence Herbicides In Corn, R. Currie, P. Geier
Kansas Agricultural Experiment Station Research Reports
A study was initiated near Garden City, KS, in 2016, comparing the weed control of several herbicide treatments applied sequentially for weed control in irrigated corn. Acuron (metolachlor + atrazine + mesotrione + bicyclopyrone), Clarity (dicamba), Corvus (isoxaflutole + thiencarbazone), Halex GT (metolachlor + glyphosate + mesotrione), and Lumax EZ (metolachlor + atrazine + mesotrione) were compared when combined at various ratios and timings. All combinations gave similar levels of weed control, allowing a producer to compare these tank mixes head-to-head based on prices alone.

Kansas Agricultural Experiment Station Research Reports
A study was initiated near Garden City, KS, in 2016, comparing the weed control of several postemergence herbicide treatments in irrigated corn. Control of kochia, Palmer amaranth, and crabgrass was 96% or more effective with all herbicides at 7 days after treatment (DAT). By 62 DAT, control of these three weed species was generally best when glyphosate, atrazine, Diflexx (dicamba) or Clarity (dicamba) were included in the herbicide mixture. Although all herbicide tank mixes increased yield compared to the untreated plots, no tank mix resulted in a superior yield.

Glyphosate-resistant Palmer amaranth has become a serious weed problem in fields following wheat harvest. A field experiment was established in 2016 near Manhattan, KS, to evaluate herbicide alternatives to glyphosate for Palmer amaranth control in wheat stubble. The two most effective postharvest herbicides for control of Palmer amaranth were Gramoxone (paraquat) or Sharpen (saflufenacil). Clarity (dicamba) and 2,4-D treatments provided suppression of Palmer amaranth, but were inconsistent, and often some plants survived and produced viable seed. The tank-mix of Clarity plus 2,4-D was more effective than either herbicide alone, but not as good as Gramoxone or Sharpen.
