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.


Fallow Weed Control With Preemergence Tank Mixes Of Sharpen, Zidua, Sencor, Banvel, Atrazine, Balance Pro, And Corvus, R. Currie, P. Geier Jan 2015

Fallow Weed Control With Preemergence Tank Mixes Of Sharpen, Zidua, Sencor, Banvel, Atrazine, Balance Pro, And Corvus, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

With the exception of the tank mix of Sharpen and Sencor, all other tank mixes that provided 100% kochia control 53 days after treatment (DAT) were three-way tank mixes of atrazine herbicide plus, Banvel, and Balance Pro or Zidua. Only two tank mixes provided 98% kochia control 143 DAT. These were also three-way tank mixes of these chemistries. Combinations of Balance Pro and Sencor were needed to provide greater than 93% control of Russian thistle 143 DAT. No tank mix provided good control of Palmer amaranth 143 DAT. However, tank mixes of Sharpen, Sencor, and Zidua provided 84% control 143 …


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.


Crabgrass Control In Spring Seeding Using Early And Late Combinations Of Prodiamine And Dithiopyr, J. Hoyle, J. Reeves Jan 2015

Crabgrass Control In Spring Seeding Using Early And Late Combinations Of Prodiamine And Dithiopyr, J. Hoyle, J. Reeves

Kansas Agricultural Experiment Station Research Reports

With less crabgrass pressure, the Kansas site showed an inhibitory effect of pre-emergent herbicides on spring tall fescue (Lolium arundinaceum) seeding and establishment. However, at the Nebraska site, greater crabgrass pressure showed a benefit of pre-emergent herbicide use in new spring seeding of tall fescue.


Late-Season Bermudagrass Control With Glyphosate, Fluazifop, And Mesotrione Combinations, J. Reeves, J. Hoyle, C. Thompson Jan 2015

Late-Season Bermudagrass Control With Glyphosate, Fluazifop, And Mesotrione Combinations, J. Reeves, J. Hoyle, C. Thompson

Kansas Agricultural Experiment Station Research Reports

All herbicide treatments at the Rocky Ford Research Center (RF) resulted in unacceptable control, as all plots resulted in 100% green bermudagrass cover by August 25, 2014. Any herbicide treatment combination that included glyphosate provided moderate or better control at Stagg Hill Golf Course (SH). Treatments not containing glyphosate showed no control throughout research trial.


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.


Efficacy Of Anthem, Anthem Atz, Solstice, Keystone Nxt, Corvus, And Surestart Ii In Glyphosate-Resistant Irrigated Corn, R. Currie, P. Geier Jan 2015

Efficacy Of Anthem, Anthem Atz, Solstice, Keystone Nxt, Corvus, And Surestart Ii In Glyphosate-Resistant Irrigated Corn, R. Currie, P. Geier

Kansas Agricultural Experiment Station Research Reports

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


Dose Responses Of Silvery-Thread Moss To Carfentrazone-Ethyl, Z. Raudenbush, S. Keeley, M. Jugulam Jan 2015

Dose Responses Of Silvery-Thread Moss To Carfentrazone-Ethyl, Z. Raudenbush, S. Keeley, M. Jugulam

Kansas Agricultural Experiment Station Research Reports

As compared with label recommendations, this research suggests that lower carfentrazone-ethyl rates and longer intervals may be effective for silvery- thread moss (STM;Bryum argenteumHedw.) control in putting greens.
