Assure Ii Alone And With Tacoma And Classic For Efficacy In Fallow, R. S. Currie, P. W. Geier
Assure Ii Alone And With Tacoma And Classic For Efficacy In Fallow, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of this trial was to compare Assure II (quizalofop) at two rates with or without tank mix partners for grass control in fallow. Assure II at either rate alone provided similar control of volunteer corn and barley. Corn control was 90% or more regardless of rating date with all herbicides except Assure II at 8.0 oz/a plus Classic (chlorimuron) at 42 days after treatment (DAT). Tacoma (fenoxaprop) at 3.5 or 5.4 oz/a added to Assure II at 8.0 oz/a improved barley control later in the season.
Katagon At Two Timings Compared To Standards In Corn, R. S. Currie, P. W. Geier
Katagon At Two Timings Compared To Standards In Corn, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of this trial was to compare Katagon (tolpyralate/nicosulfuron) to standard treatments for weed control in corn. Katagon plus atrazine applied early postemergence was as effective as any herbicide tested on the weeds present. When application timing was delayed to late postemergence, most herbicides were less effective. Early season corn injury was minor and did not persist. Although most herbicide treatments increased yields relative to the non-treated control, yields were generally best when any treatment was applied early postemergence.
Single And Split Herbicide Applications For Efficacy In Corn, R. S. Currie, P. W. Geier
Single And Split Herbicide Applications For Efficacy In Corn, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of this study was to compare season-long weed control from single and sequential herbicide applications in corn. Control of all weed species was generally good (90% or more) early in the season regardless of preemergence (PRE) herbicide. However, Russian thistle and Palmer amaranth control was best later in the season when a PRE herbicide was followed by a postemergence (POST) treatment. While all herbicide treatments increased yields compared to the untreated control, yields were greatest when Lumax EZ PRE (atrazine/mesotrione/metolachlor) was followed by Acuron (atrazine/bicyclopyrone/mesotrione/metolachlor) and glyphosate POST.
Outlook Alone And In Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Outlook Alone And In Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of the study was to compare Outlook (dimethenamid) alone and in various tank mixtures for season-long weed control in corn. Kochia control with most herbicides was 95% or more late in the season. However, Russian thistle control did not exceed 83% with any herbicide tested. Palmer amaranth control at 59 days after the postemergence treatments was similar among all herbicides, while green foxtail control was 93% or more with each treatment. All herbicides increased grain yields relative to the untreated control, but corn treated with Outlook or Verdict alone yielded less grain than the best yielding plots.
Impact And Liberty Rates And Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Impact And Liberty Rates And Mixtures For Efficacy In Corn, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of the study was to compare Impact (topramezone), Liberty (glufosinate) and a premixture of the two herbicides (Sinate) for efficacy in corn. Rates for each herbicide were 0.75 and 1.0 oz/a for Impact, 22 and 30 oz/a for Liberty, and 21 and 28 oz/a for Sinate. Impact and Sinate, each at the high rates, and Status plus glyphosate provided the best kochia control for corn late in the season. These treatments, along with the low rate of Impact controlled crabgrass the best. Status was also the best treatment for Russian thistle, Palmer amaranth, and green foxtail control. The …
