Influence of Carrier Volume and Nozzle Selection on Palmer Amaranth Control

S. T. Berger; M. H. Dobrow; J. A. Ferrell; et al. Peanut Science 2014. doi:10.3146/ps13-20.1

Other claims from this paper (8)

Intervention effect XR nozzles provided more spray coverage than AI nozzles.
Intervention effect Nozzle type did not change herbicide efficacy in field trials, and nozzle selection had no significant main or interaction effect.
Association The carrier volume by application timing interaction was significant at each location for Palmer amaranth control.
Intervention effect Applications at 5 to 10 cm tall Palmer amaranth with 94, 187 or 281 L/ha provided over 90% control in 2008 at Williston, FL.
Intervention effect Applications to 15 to 20 cm tall weeds provided less control.
Intervention effect Applications to smaller weeds provided sufficient control at any carrier volume tested.
Intervention effect Carrier volume did not affect control of small weeds.
Recommendation Growers should apply lactofen to smaller Palmer amaranth plants for the most effective control in peanut.

Evaluating herbicide programs for peanut response and weed control

Prasanna Kharel; Pratap Devkota; Gregory MacDonald; et al. Crop Forage & Turfgrass Management 2022. doi:10.1002/cft2.20191

Other claims from this paper (11)

Intervention effect Peanut injury did not differ among herbicides in 2019 at 2 WA-PRE.
Intervention effect Flumioxazin caused about twofold greater peanut injury in 2020.
Intervention effect Diclosulam gave lower Palmer amaranth control.
Intervention effect S-metolachlor and dimethenamid-P gave at least 10% lower carpetweed control.
Observation Postemergence Palmer amaranth control exceeded 94% except with diclosulam.
Observation Peanut injury at 2 WA-EPOST was at most 28% and minimal by 8 WA-EPOST.
Intervention effect Herbicide treatment yield resembled weedfree control.
Intervention effect Acifluorfen gave at least 99% Palmer amaranth control.
Intervention effect Acifluorfen reduced Palmer amaranth biomass to at most 0.3 g per plant.
Intervention effect 2,4-DB plus pyroxasulfone plus carfentrazone controlled Palmer amaranth similarly to acifluorfen.
Recommendation Authors recommend effective PRE followed by EPOST paraquat plus acetochlor plus bentazon.

Evaluation of Flumioxazin andS-metolachlor Rate and Timing for Palmer Amaranth (Amaranthus palmeri) Control in Sweetpotato

Stephen L. Meyers; Katherine M. Jennings; Jonathan R. Schultheis; et al. Weed Technology 2010. doi:10.1614/wt-d-09-00057.1

Other claims from this paper (13)

Intervention effect Sequential flumioxazin and S-metolachlor immediately after transplanting gave over 90% season-long Palmer amaranth control.
Intervention effect S-metolachlor alone immediately after transplanting gave 80 to 93% weed control in 2007.
Intervention effect S-metolachlor alone immediately after transplanting gave 92 to 96% weed control in 2008.
Intervention effect Flumioxazin followed by S-metolachlor at 2 WAP gave 90% control in 2007.
Intervention effect Flumioxazin followed by S-metolachlor at 2 WAP gave 38 to 79% control in 2008.
Intervention effect S-metolachlor alone at 2 WAP did not provide acceptable weed control.
Intervention effect Weed control was similar across S-metolachlor rates.
Intervention effect In 2008, flumioxazin at 109 g ha−1 gave greater weed control than 91 g ha−1.
Intervention effect Herbicide treatment caused minimal sweetpotato injury below 3%.
Intervention effect Storage root length-to-width ratio for Beauregard was 2.5 in 2007, similar across treatments.
Intervention effect Storage root length-to-width ratio for Beauregard was 2.4 in 2008, similar across treatments.
Intervention effect Storage root length-to-width ratio for Covington was 1.9 in 2008, similar across treatments.
Recommendation The authors recommend pretransplant flumioxazin followed by posttransplant S-metolachlor for Palmer amaranth control in sweetpotato.

Growth and fecundity of Palmer amaranth escaping glufosinate in cotton with and without grass competition

Eric A.L. Jones; Colden L. Bradshaw; Diego J. Contreras; et al. Weed Technology 2024. doi:10.1017/wet.2024.68

Other claims from this paper (7)

Intervention effect No plants survived the sequential glufosinate applications
Intervention effect Apical and circumferential growth of surviving plants was reduced by more than 44% compared with WFIC and WFNC plants
Intervention effect Biomass of surviving plants was reduced by more than 62% compared with WFIC and WFNC
Intervention effect Fecundity of surviving plants was reduced by more than 73% compared with WFNC plants
Intervention effect Plants that survived glufosinate were as fecund as WFIC plants only in the grass competition experiment
Association A glufosinate-treated grass weed may not have a significant interspecific competition effect on surviving Palmer amaranth
Recommendation Glufosinate should be applied to 5 to 7 cm Palmer amaranth to stop vegetative and reproductive capacities
