Rimsulfuron is commonly used to control common lambsquarters (Chenopodium album L.) and redroot pigweed (Amaranthus retroflexus L.) in potato (Solanum tuberosum L.) fields. Comparing rimsulfuron absorption and metabolism patterns in these two weed species with potato could provide crucial information to optimise herbicide application in the field. Hence, an experiment was conducted in Denmark and Iran to evaluate the absorption and metabolism of rimsulfuron at the application rate of 30 g ha−1 in potato, common lambsquarters and redroot pigweed. Seedlings at the 2- to 4-leaf stage were foliar treated with rimsulfluron and plant tissues were harvested at 0, 1, 4, 8, 24 and 48 h after treatment (HAT) to measure the rate of herbicide absorption and metabolism using HPLC. Absorption and metabolism of rimsulfuron differed between potato and weed seedlings. This explains the different susceptibility to rimsulfuron in potato, redroot pigweed and common lambsquarters. Redroot pigweed, the most sensitive species in this study, showed the highest rate of absorption and lowest rate of the herbicide metabolism. Common lambsquarters, a species with an intermediate sensitivity, revealed moderate rimsulfuron absorption and metabolism levels. Potato, the tolerant crop species to rimsulfuron, showed the lowest and highest rate, respectively, of absorption and metabolism.

叶面喷施利莫磺隆在马铃薯,马铃薯小腿(Chenopodium album L.)和红根藜(Amaranthus retroflexus L.)中的吸收和代谢。

Rimsulfuron通常用于防治马铃薯(Solanum tuberosum L.)田间的常见羊腿(Cheopodium album L.)和赤根杂草(Amaranthus retroflexus L.)。比较这两种杂草物种与马铃薯中的嘧磺隆吸收和代谢模式,可以为优化除草剂在田间的应用提供关键信息。因此,在丹麦和伊朗进行了一项实验,以评估施用量为30 g ha -1时利福磺隆的吸收和代谢在马铃薯,常见的羊腿和紫菜中。将2至4阶段的幼苗用rimsulfluron进行叶面处理,并在处理(HAT)后0、1、4、8、24和48 h收获植物组织,以使用HPLC测量除草剂的吸收和代谢速率。马铃薯和杂草幼苗中利福磺隆的吸收和代谢不同。这解释了马铃薯,红根藜和普通羊羔对瑞磺隆的敏感性不同。这项研究中最敏感的物种-紫菜杂草显示出最高的吸收率和最低的除草剂代谢率。普通的羊腿,一种中等敏感性的物种,显示出适度的rimsulfuron吸收和代谢水平。马铃薯对瑞磺隆的耐受性分别为最低和最高。
