Preemergence Weed Control With Fultime Nxt And Competitive Standards In Grain Sorghum, R. Currie, P. Geier
Preemergence Weed Control With Fultime Nxt And Competitive Standards In Grain Sorghum, R. Currie, P. Geier
Kansas Agricultural Experiment Station Research Reports
At 71 days after treatment, FulTime NXT (acetochlor + atrazine) at 2.5 or 3.0 qt/a and Lumax EZ (S-metolachlor + atrazine + mesotrione) at 2.0 qt/a were the only treatments to control Palmer amaranth at 90% or more. All treatments provided similar velvetleaf control. Green foxtail control was 75 to 83% with all rates of FulTime NXT or Lumax EZ. Sorghum receiving FulTime NXT at 2.5 or 3.0 qt/a or Lumax EZ yielded significantly more than the control treatments.
Efficacy Of Anthem Maxx, Solstice, Cadet, Roundup Powermax, And Competitive Standards In Irrigated Corn, R. Currie, P. Geier
Efficacy Of Anthem Maxx, Solstice, Cadet, Roundup Powermax, And Competitive Standards In Irrigated Corn, R. Currie, P. Geier
Kansas Agricultural Experiment Station Research Reports
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 72 bu/a more grain than non-treated corn.
Efficacy Of Preemergence Or Early Postemergence Weed Control With Keystone Nxt, Hornet Wdg, Atrazine, Surestart Ii, Lumax Ez, And Resicore, R. Currie, P. Geier
Efficacy Of Preemergence Or Early Postemergence Weed Control With Keystone Nxt, Hornet Wdg, Atrazine, Surestart Ii, Lumax Ez, And Resicore, R. Currie, P. Geier
Kansas Agricultural Experiment Station Research Reports
Control of buffalobur was complete regardless of herbicide used. Velvetleaf and puncturevine control, although not perfect, was excellent by all herbicides. The premix of SureStart II (acetochlor + flumetsulam + clopyralid) with atrazine and Durango DMA (glyphosate) applied early postemergence and the preemergence herbicides Resicore (acetochlor + mesotrione + clopyralid) with atrazine and Lumax EZ (S-metolachlor + atrazine + mesotrione) provided excellent Palmer amaranth control. The early postemergence treatment of SureStart II plus atrazine and Durango DMA was the only treatment to provide excellent control of green foxtail.
Weed Control With Accent, Callisto, Isoxadifen, Impact, Cinch, Dicamba, And Atrazine In Irrigated Corn, R. Currie, P. Geier
Weed Control With Accent, Callisto, Isoxadifen, Impact, Cinch, Dicamba, And Atrazine In Irrigated Corn, R. Currie, P. Geier
Kansas Agricultural Experiment Station Research Reports
Some timings and combinations of the herbicides tested in this study controlled Palmer amaranth, kochia, quinoa, Russian thistle, and green foxtail from 95 to 100% 51 days after postemergence application (DA-B). Accent (nicosulfuron) plus Callisto (mesotrione) and isoxadifen alone postemergence provided 88% Palmer amaranth control at 51 DA-B. Kochia control was 92 and 90% when Accent plus Callisto and isoxadifen alone or with atrazine and Dicamba XP (dicamba) was applied postemergence following Cinch (S-metolachlor) preemergence application. Crabgrass control with preemergence followed by postemergence treatments exceeded 89%. Crabgrass control was 83 and 88% when no preemergence herbicide was applied …
Efficacy Of Preemergence And Sequential Applications With Corvus, Atrazine, Starane, Balance, Anthem, Capreno, Diflexx And Halex Gt In Irrigated Corn, R. Currie, P. Geier
Efficacy Of Preemergence And Sequential Applications With Corvus, Atrazine, Starane, Balance, Anthem, Capreno, Diflexx And Halex Gt In Irrigated Corn, R. Currie, P. Geier
Kansas Agricultural Experiment Station Research Reports
Control of kochia and quinoa was 98 to 100% regardless of herbicide treatment at 48 days after post applications (DAPT), and 95% or more with all herbicides for Russian thistle. Palmer amaranth control was slightly less with preemergent (PRE) treatments alone compared to sequential treatments. Corvus (isoxaflutole + thiencarbazone) plus atrazine, Starane Ultra (fluroxypyr), and nonionic surfactant preemergence controlled crabgrass by 88%; whereas all other treatments provided 91% or more crabgrass control. Corn with the best herbicide treatments yielded 33 to 66 bu/a more than untreated corn.
