Single And Sequential Applications Of Anthem Maxx, Solstice, Acuron, Balance Flexx, Corvus, Halex Gt, Verdict, Sharpen, Glyphosate, And Atrazine In Irrigated Corn, R. Currie, P. Geier Jan 2017

Single And Sequential Applications Of Anthem Maxx, Solstice, Acuron, Balance Flexx, Corvus, Halex Gt, Verdict, Sharpen, Glyphosate, And Atrazine In Irrigated 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 and their sequential application for weed control in irrigated corn. Quinoa and common sunflower control was excellent. All sequential herbicide treatments provided excellent control of kochia, velvetleaf, Palmer amaranth, and green foxtail. Single applications at the V4 stage, although still good, showed a reduced level of Palmer amaranth and green foxtail control compared to sequential treatments.


Armezon Pro, Status, Verdict, Glyphosate, Zidua, And Atrazine For Sequential Weed Control In Glyphosate-Resistant Corn, R. Currie, P. Geier Jan 2017

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 in irrigated corn. Kochia control was 95% or more with all treatments at 1 day after late postemergence application (1 DALP) and 100% regardless of treatment at 63 days after late postemergence application (63 DALP). Palmer amaranth and green foxtail control was 98 to 100% and 83 to 93%, respectively, with all preemergence treatments at 1 DALP. A second late postemergence application was needed to achieve 100% control of Palmer amaranth and green foxtail 63 DALP. The single early postemergence …


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.


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.
