Resicore and Glyphosate Application Timings in Corn

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 ...

Single and Sequential Applications of Anthem Maxx, Solstice, Acuron, Balance Flexx, Corvus, Halex GT, Verdict, Sharpen, Glyphosate, and Atrazine in Irrigated Corn

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 ...

Efficacy of Preplant and Early Postemergence Herbicides in Corn

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 + ...

Clarity, Laudis, Diflexx Duo, Atrazine, and Glyphosate for Efficacy in Corn

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% ...

Winter and Early Spring Herbicides for Kochia Control in Fallow

A study was initiated near Garden City, KS, in fall of 2015 and spring of 2016 comparing the weed control of several herbicide treatments and their time of application for kochia control in fallow. All herbicide treatments applied in December 2015 provided 99 or 100% kochia control in early spring. However, control declined to less than 60% with these treatments by June 8, 2016. ...

Efficacy of Anthem Maxx, Solstice, Cadet, Roundup PowerMax, and Competitive Standards in Irrigated Corn

Control of Palmer amaranth and green foxtail was generally best when herbicides were applied as sequential treatments of preemergence (PRE) followed by late postemergence (LPOST) or as postemergence (POST) alone. Velvetleaf and puncturevine control was 95 and 93% or more, respectively, regardless of herbicide or application timing. Corn receiving herbicide treatments yielded 42 to ...

Palmer Amaranth Control and Sorghum Response to Tank Mixtures of Huskie

Although Huskie treatments caused significant chlorosis, the sorghum recovered fully and chlorosis did not affect yield. All tank mixes of Huskie provided good Palmer amaranth control at all rating dates. Starane NXT provided poor Palmer amaranth control at all rating dates. All tank mixes of Huskie significantly elevated yield compared to the untreated controls or Starane NXT ...

Weed Control in Irrigated Corn with Combinations of Corvus, Balance Flexx, Capreno, Laudis, Harness, Atrazine, Glyphosate, Dual, and Diflexx

Most preemergence treatments followed by postemergence treatments provided better Palmer amaranth control than preemergence treatments alone or early postemergence treatments alone (Table 2). The better treatments provided good control of Palmer amaranth, kochia, Russian thistle, crabgrass, green foxtail, and shattercane. All treatments elevated yield over the untreated control.

Efficacy of Anthem, Anthem ATZ, Solstice, Keystone NXT, Corvus, and Surestart II in Glyphosate-Resistant Irrigated Corn

The best treatments provided excellent green foxtail, crabgrass, or shattercane control. All treatments dramatically increased corn yield compared to the control.
