Abstract

The importance of PRE herbicide applications in cotton has increased since the evolution of glyphosate-resistant (GR) Palmer amaranth. Cotton producers are relying on residual herbicides for control of Palmer amaranth, as POST options are limited or ineffective. S-Metolachlor, acetochlor, fomesafen, and dicamba all provide PRE control of Palmer amaranth; however, little is known about the effect of irrigation rate on incorporation and herbicidal efficacy. In 2015, an experiment was conducted on fine sand and loamy sand soils to evaluate the influence of irrigation volume (0.0 to 12.7 mm ha−1) on Palmer amaranth control with PRE herbicides. Irrigation volume after herbicide application was significant for both S-metolachlor and acetochlor. Efficacy of S-metolachlor was greatest in plots receiving 6.4 and 12.7 mm of irrigation where Palmer amaranth biomass was reduced to 4 and 2% of a nontreated control (NTC), respectively, compared with 61% in plots with the 0-mm irrigation treatment. Palmer amaranth control by acetochlor incorporated at 3.2- to 12.7-mm irrigation did not differ but did reduce Palmer amaranth biomass compared with the 1.6-mm irrigation rate. Irrigation volume was not significant for the soil incorporation of fomesafen or dicamba. Across all herbicides, fomesafen-treated plots provided the most consistent control of Palmer amaranth, reducing its biomass to < 3% of NTC at all irrigation rates. Dicamba provided the least and most inconsistent control of Palmer amaranth, producing 17 to 51% of NTC biomass.

En algodón, la importancia de las aplicaciones de herbicidas PRE ha aumentado desde la evolución de Amaranthus palmeri resistente a glyphosate (GR). Los productores de algodón están dependiendo de herbicidas residuales para el control de A. palmeri, ya que las opciones POST son limitadas o inefectivas. S-metolachlor, acetochlor, fomesafen, y dicamba brindan control PRE de A. palmeri. Sin embargo, se conoce poco acerca del efecto de la dosis de riego sobre la incorporación en el suelo y la eficacia del herbicida. En 2015, se realizó un experimento en un suelo arenoso fino y en uno arenoso limoso para evaluar la influencia del volumen de riego (0.0 a 12.7 mm ha−1) sobre el control de A. palmeri con herbicidas PRE. El volumen de riego después de la aplicación del herbicida fue significativo para S-metolachlor y acetochlor. La eficacia de S-metolachlor fue mayor en parcelas que recibieron 6.4 y 12.7 mm de riego donde la biomasa de A. palmeri se redujo a 4 a 2% del testigo sin tratamiento (NTC), respectivamente, comparado con 61% en parcelas con 0 mm de riego. El control de A. palmeri con acetochlor incorporado con riego de 3.2 a 12.7 mm no difirió, pero redujo la biomasa al compararse con la dosis de riego de 1.6 mm. El volumen de riego no fue significativo para la incorporación en el suelo de fomesafen y dicamba. Entre todos los herbicidas, las parcelas tratadas con fomesafen brindaron el control más consistente de A. palmeri, reduciendo la biomasa a < 3% del NTC en todas las dosis de riego. Dicamba brindó el más inconsistente y el menor control A. palmeri, produciendo 17 a 51% de biomasa al compararse con el NTC.
