Abstract

There are limited PRE herbicide options available to provide residual weed control in sweet corn grown on organic soils in the Everglades Agricultural Area (EAA). Field studies were established to determine the efficacy of PRE applied saflufenacil + dimethenamid-P at six rates ranging from 10 + 88 to 319 + 2802 g ai ha−1 on weed control and sweet corn tolerance on organic soils in the EAA in 2011 and 2012. Saflufenacil + dimethenamid-P is a premix recently labeled for PRE weed control in field corn at 50 + 438 to 90 + 788 g ha−1 depending on soil texture. There was no phytotoxic effect of PRE applied saflufenacil + dimethenamid-P on sweet corn. At 42 d after treatment, common lambsquarters, common purslane, and spiny amaranth were controlled 90% with saflufenacil + dimethenamid-P at 58 + 508, 71 + 622, and 58 + 512 g ha−1, respectively. Sweet corn yield at 95% of the weed-free yield was estimated to be obtained at 69 + 606 g ha−1 of saflufenacil + dimethenamid-P. Our results show that saflufenacil + dimethenamid-P at 69 + 606 to 71 + 622 g ha−1 controlled three common weeds and maintained acceptable sweet corn yield. Labeled rates of saflufenacil + dimethenamid-P for field corn on mineral soils were adequate for weed control in sweet corn on organic soils.

Existen pocas opciones de herbicidas PRE disponibles para el control residual de malezas en maíz dulce producido en suelos orgánicos en el Área Agrícola de los Everglades (EAA). Se establecieron experimentos de campo para determinar la eficacia de saflufenacil + dimethenamid-P aplicados PRE a seis dosis variando de 10 + 88 a 319 + 2802 g ai ha−1 para el control de malezas y la tolerancia del maíz dulce en suelos orgánicos en el EAA en 2011 y 2012. Saflufenacil + dimethenamid-P es una premezcla recientemente registrada para el control PRE de malezas en maíz para grano con dosis de 50 + 438 a 90 + 788 g ha−1 dependiendo de la textura del suelo. No hubo efecto fitotóxico de saflufenacil + dimethenamid-P aplicado PRE en maíz dulce. A 42 d después del tratamiento, Chenopodium album, Portulaca oleracea, y Amaranthus spinosus fueron controlados en 90% con saflufenacil + dimethenamid-P a 58 + 508, 71 + 622, y 58 + 512 g ha−1, respectivamente. El rendimiento del maíz dulce a 95% del rendimiento del testigo libre de malezas se estimó que se pudo obtener con 69 + 606 g ha−1 de saflufenacil + dimethenamid-P. Nuestros resultados muestran que saflufenacil + dimethenamid-P de 69 + 606 a 71 + 622 g ha−1 controló tres de las malezas más comunes y mantuvo rendimientos aceptables en el maíz dulce. Las dosis en la etiqueta de saflufenacil + dimethenamid-P para maíz para grano en suelos minerales fueron adecuadas para el control de malezas en maíz dulce en suelos orgánicos.
