Atrazine, Clarity, Verdict, And Armezon Pro Application Timings For Weed Control In Fallow, R. Currie, P. Geier Jan 2017

Atrazine, Clarity, Verdict, And Armezon Pro Application Timings For Weed Control In Fallow, 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 and their time of application in fallow. A single application of Clarity (dicamba) and atrazine applied on March 3, 2016, did not provide more than 93% control of kochia, Russian thistle, and Palmer amaranth on June 9. All other treatments provided 95% or greater control at the evaluation conducted June 9. Three applications were needed to provide 90% or greater control of all three species through July 6.


Preemergence And Post-Harvest Kochia Control In Wheat, R. Currie, P. Geier Jan 2017

Preemergence And Post-Harvest Kochia Control In Wheat, 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 preemergence and post-harvest for kochia control in wheat. Clarity (dicamba) with any premix partner applied preemergence provided less than 30% kochia control at evaluations conducted on July 25 and August 12, 2016. The addition of glyphosate plus Distinct (dicamba + diflufenzopyr) postemergence increased control 45 to 66% compared to preemergence treatments alone on July 25 and August 12. However, all treatments receiving a postemergence application controlled kochia similarly on August 12.


Clarity, Laudis, Diflexx Duo, Atrazine, And Glyphosate For Efficacy In Corn, R. Currie, P. Geier Jan 2017

Clarity, Laudis, Diflexx Duo, Atrazine, And Glyphosate For Efficacy 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. Control of quinoa, Russian thistle, and kochia was excellent with all herbicide treatments, and late-season control of common sunflower was 100% with all treatments except for those applied preemergence alone. Most treatments controlled green foxtail 95% or more, except Corvus (isoxaflutole + thiencarbazone) plus atrazine preemergence, or the early postemergence (EPOST) treatments containing Liberty 280 (glufosinate). Liberty 280 severely injured the non- Liberty Link corn in this trial, but all other herbicide-treated corn yielded 21 to 45 bu/a more ...


Resicore And Glyphosate Application Timings In Corn, R. Currie, P. Geier Jan 2017

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 Jan 2017

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.
