Efficacy Of Lumax Ez, Atrazine, Acuron, Armezon, Sharpen, Outlook, Verdict, And Prowl H2o In Irrigated Glyphosate-Resistant Corn, R. Currie, P. Geier Jan 2015

Efficacy Of Lumax Ez, Atrazine, Acuron, Armezon, Sharpen, Outlook, Verdict, And Prowl H2o In Irrigated Glyphosate-Resistant Corn, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

All treatments provided statistically superior control of Palmer amaranth compared to the control or a single application of glyphosate. All treatments provided excellent control of all other weed species. Although all herbicide tank mixes elevated corn yield compared to the control, there were no statistically significant differences among herbicides in their ability to do so.


Weed Control In Irrigated Corn With Combinations Of Corvus, Balance Flexx, Capreno, Laudis, Harness, Atrazine, Glyphosate, Dual, And Diflexx, R. Currie, P. Geier Jan 2015

Weed Control In Irrigated Corn With Combinations Of Corvus, Balance Flexx, Capreno, Laudis, Harness, Atrazine, Glyphosate, Dual, And Diflexx, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

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.


Palmer Amaranth Control And Sorghum Response To Tank Mixtures Of Huskie, R. Currie, P. Geier Jan 2015

Palmer Amaranth Control And Sorghum Response To Tank Mixtures Of Huskie, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

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 treatments.


Sequential Treatments Of Rimsulfuron, Mesotrione, Thifensulfuron, Balance Flexx, Cinch, Cinch Atz, And Prowl H2o Mixtures For Weed Control In Irrigated Corn, R. Currie, P. Geier Jan 2015

Sequential Treatments Of Rimsulfuron, Mesotrione, Thifensulfuron, Balance Flexx, Cinch, Cinch Atz, And Prowl H2o Mixtures For Weed Control In Irrigated Corn, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

No treatment with less than 1.5 lb/a atrazine provided commercially acceptable Palmer amaranth control. The best level of Palmer amaranth control was produced by treatments that had good preemergence control augmented by a postemergence application with two or more modes of action that contained 0.5 lb/a atrazine. All treatments provided excellent kochia control. The best Russian thistle treatments provided from 77 to 88% control. The best foxtail or crabgrass treatments provided from 91 to 94% control. Combinations of preemergence treatments followed by a postemergence treatment achieved excellent shattercane control.


Weed Control And Crop Tolerance In Inzen Grain Sorghum With Zest Tank Mixtures, R. Currie, P. Geier Jan 2015

Weed Control And Crop Tolerance In Inzen Grain Sorghum With Zest Tank Mixtures, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

Although preemergence applications of Cinch ATZ provided excellent green foxtail control, it did not provide commercially acceptable levels of Palmer amaranth or crabgrass control. All postemergence tank mixes of Zest raised the level of control achieved by the preemergence applications of Cinch ATZ to excellent levels for these species. With the exception of the Huskie tank mix, which provided excellent Palmer amaranth control, all other postemergence programs provided only adequate control of Palmer amaranth, crabgrass, or green foxtail. Weed pressure of these species was extreme. Under conditions of extreme weed pressure, a foundation treatment of Cinch ATZ followed by a …


Herbicide Evaluation For Control Of Kochia And Palmer Amaranth In Teff Grass, J. D. Holman, C. Thompson, T. Roberts, S. Maxwell Jan 2015

Herbicide Evaluation For Control Of Kochia And Palmer Amaranth In Teff Grass, J. D. Holman, C. Thompson, T. Roberts, S. Maxwell

Kansas Agricultural Experiment Station Research Reports

Eleven postemergence herbicide treatments were applied to teff grown for forage to evaluate Palmer amaranth and kochia control, as well as crop tolerance. Effective Palmer amaranth control was achieved with all herbicide treatments, while less than satisfactory kochia control was obtained with atrazine and Harmony. Clarity, 2,4-D, and Huskie applied alone appeared to control kochia, but kochia density was low in the plots. Had the kochia population been higher, similar efficacy ratings may have been attained. Huskie or atrazine caused the most injury to teff. The first harvest suggests these herbicides reduced forage yield to less than 3,000 lb/a.
