Field studies were conducted to determine sweetpotato tolerance to and weed control from management systems that included linuron. Treatments included flumioxazin preplant (107 g ai ha−1) followed by (fb) S-metolachlor (800 g ai ha−1), oryzalin (840 g ai ha−1), or linuron (280, 420, 560, 700, and 840 g ai ha−1) alone or mixed with S-metolachlor or oryzalin applied 7 d after transplanting. Weeds did not emerge before the treatment applications. Two of the four field studies were maintained weed-free throughout the season to evaluate sweetpotato tolerance without weed interference. The herbicide program with the greatest sweetpotato yield was flumioxazin fb S-metolachlor. Mixing linuron with S-metolachlor did not improve Palmer amaranth management and decreased marketable yield by up to 28% compared with flumioxazin fb S-metolachlor. Thus, linuron should not be applied POST in sweetpotato if Palmer amaranth has not emerged at the time of application.

除草剂系统，包括用于控制甘薯中棕榈苋 (Amaranthus palmeri) 的 linuron

进行了田间研究以确定甘薯对包括利谷隆在内的管理系统的耐受性和杂草控制。处理包括氟咪嗪预植（107 g ai ha-1) 后跟 (fb)小号-异丙甲草胺（800 克艾哈-1), oryzalin (840 克艾哈-1), 或 linuron (280, 420, 560, 700, 和 840 g ai ha-1) 单独或混合小号-异丙甲草胺或安草灵在移栽后7 d施用。在处理应用之前没有出现杂草。四项田间研究中的两项在整个季节保持无杂草，以评估甘薯耐受性而不受杂草干扰。甘薯产量最高的除草剂方案是氟噻嗪 fb小号-异丙甲草胺。将利农隆与小号-异丙甲草胺没有改善帕默苋菜的管理，与氟米恶嗪 fb 相比，可销售的产量降低了 28%小号-异丙甲草胺。因此，如果在施用时帕尔默苋菜尚未出现，则不应在甘薯中使用 POST 施用利奴隆。
