Abstract

Four field experiments were conducted in Louisiana and Mississippi in 2009 and 2010 to evaluate POST herbicides treatments with tembotrione applied alone or as a prepackaged mixture with thiencarbazone for weed control in corn. Treatments included tembotrione at 92 g ai ha−1, thiencarbazone : tembotrione at 15 : 76 g ai ha−1, atrazine at 2,240 g ai ha−1, glufosinate at 450 g ai ha−1, glyphosate at 860 g ae ha−1, and coapplications of tembotrione or thiencarbazone : tembotrione with atrazine, glufosinate, or glyphosate. All treatments were applied to 26-cm corn in the V4 growth stage. Treatments containing thiencarbazone : tembotrione and those with tembotrione controlled barnyardgrass, browntop millet, entireleaf morningglory, hophornbeam copperleaf, johnsongrass, Palmer amaranth, and velvetleaf 85 to 96% and 43 to 97% 28 d after treatment and at corn harvest, respectively. Corn yield ranged from 9,200 to 10,420 kg ha−1 and was greater than the nontreated control following all herbicide treatments, except atrazine alone. Results indicated that thiencarbazone : tembotrione or tembotrione POST is an option for weed management in corn, and applications of thiencarbazone : tembotrione would be strongly encouraged where rhizomatous johnsongrass is problematic.

Se realizaron cuatro experimentos de campo en Lousiana y Mississippi en 2009 y 2010 para evaluar tratamientos de herbicidas POST con tembotrione aplicado solo o en mezcla pre-empacada con thiencarbazone para el control de malezas en maíz. Los tratamientos incluyeron tembotrione a 92 g ai ha−1, thiencarbazone:tembotrione a 15:76 g ai ha−1, atrazine a 2,240 g ai ha−1, glufosinate a 450 g ai ha−1, glyphosate a 860 g ae ha−1, y co-aplicaciones de tembotrione o thiencarbazone:tembotrione con atrazine, glufosinate, o glyphosate. Todos los tratamientos fueron aplicados a maíz de 26 cm en el estado de crecimiento V4. Los tratamientos que contenían thiencarbazone:tembotrione y aquellos con tembotrione controlaron Echinochloa crus-galli, Urochloa ramosa, Ipomoea hederacea var. integriuscula, Acalypha ostryifolia, Sorghum halepense, Amaranthus palmeri, y Abutilon theophrasti 85 a 96% y 43 a 97% 28 d después del tratamiento y al momento de la cosecha del maíz, respectivamente. El rendimiento del cultivo varió de 9,200 a 10,420 kg ha−1 y fue mayor que el testigo sin tratamiento en todos los tratamientos con herbicidas, con la excepción de solo atrazine. Los resultados indicaron que thiencarbazone:tembotrione o tembotrione POST es una opción para el manejo de malezas en maíz, y aplicaciones de thiencarbazone:tembotrione serían altamente recomendadas donde S. halepense con rizomas es problemático.
