Abstract

Field experiments were conducted at the North Central Agricultural Research Station in Fremont, OH, in 2006 and 2007, to evaluate tolerance of banana pepper to S-metolachlor and clomazone, and the efficacy of these herbicides on green and giant foxtail, common lambsquarters, and common purslane. The crop was machine-transplanted in late spring of each year. Pretransplant (PRETP) herbicide treatments included two S-metolachlor rates (534 and 1,070 g ai ha−1), two clomazone rates (560 and 1,120 g ai ha−1), and four tank mixes of S-metolachlor plus clomazone (534 + 560 g ha−1, 1,070 + 560 g ha−1, 534 + 1,120 g ha−1, and 1,070 + 1,120 g ha−1). Crop injury and weed control data were collected at 2 and 4 wk after treatment (WAT). The crop was harvested two times from August to September. Minor crop injury was observed at 2 WAT only in 2006 and in plots treated with S-metolachlor, alone or in combination with clomazone. In 2007, slight crop injury at 6 WAT in most herbicide-treated plots was mostly related to weeds that grew regardless of herbicide treatment. In general, S-metolachlor provided less weed control than did clomazone or tank mixes of S-metolachlor plus clomazone. Clomazone did not reduce yield of banana pepper. Registration of clomazone would provide banana pepper growers an opportunity to control weeds caused by late emergence or poor initial control following a burndown herbicide application.

Experimentos de campo fueron realizados en la Estación de Investigación Agrícola del Centro Norte en Fremont, Ohio, en 2006 y 2007, para evaluar la tolerancia del pimiento banano a S-metolachlor y clomazone, y la eficacia de estos herbicidas para el control de Setaria viridis, Setaria faberi, Chenopodium album, y Portulaca oleracea. El cultivo fue trasplantado mecánicamente tarde en la primavera en ambos años. Los tratamientos de herbicidas pre-trasplante (PRETP) incluyeron dos dosis de S-metolachlor (534 y 1,070 g ai ha−1), dos dosis de clomazone (560 y 1,120 g ai ha−1), y cuatro mezclas en tanque de S-metolachlor más clomazone (534 + 560 g ha−1, 1,070 + 560 g ha−1, 534 + 1,120 g ha−1, y 1,070 + 1,120 g ha−1). Se colectaron datos de daño al cultivo y de control de malezas a 2 y 4 semanas después del tratamiento (WAT). El cultivo se cosechó dos veces entre Agosto y Septiembre. Se observó un poco de daño en el cultivo a 2 WAT solamente en 2006 y en parcelas tratadas con S-metolachlor, solo o en combinación con clomazone. En 2007, un ligero daño en el cultivo a 6 WAT en la mayoría de las parcelas tratadas con herbicidas estuvo mayoritariamente relacionado a malezas que crecieron sin importar el tratamiento de herbicidas. En general, S-metolachlor brindó menos control de malezas que clomazone o que las mezclas en tanque de S-metolachlor más clomazone. El clomazone no redujo el rendimiento del pimiento banano. El registro de clomazone proveería a los productores de pimiento banano de una oportunidad para el control de malezas producto de emergencia tardía o de un control inicial pobre antes del trasplante.
