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 …
Fallow Weed Control With Liberty And Enlist One Tank Mixtures And Application Timings, R. S. Currie, P. W. Geier
Fallow Weed Control With Liberty And Enlist One Tank Mixtures And Application Timings, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
This study evaluated Liberty (glufosinate) and Enlist One (2,4-D choline) at three application timings and with various tank mix partners for weed control in fallow. Most herbicides tested controlled 94% or more of volunteer sorghum 17 days after the late postemergence treatments in the season. Conversely, Palmer amaranth and crabgrass control was less than 90% with most herbicides. However, control of these species was good when Tricor, or Zidua plus OpTill were applied preemergence followed by Liberty or Liberty and Enlist One late postemergence.
