Disappearance of pendimethalin in the soil of chickpea (Cicer arietinum L.) at 0-110 days, and terminal residues in plant samples have been studied under field conditions. Pendimethalin was applied as pre-emergence herbicide at 750, 350 and 180 g a.i. ha(-1) in winter, in chickpea crop. The dissipation of pendimethalin in the chickpea field soil conditions followed first order kinetics showing a half-life of 11.23 days averaged over all doses. Low pendimethalin residues were found in plant samples. 0.025, 0.015, <0.001 μg g(-1) residues of pendimethalin were found in grains at 750, 350 and 185 g a.i. ha(-1) treatments, respectively. Much lower pendimethalin residues were found in straw viz. 0.015 to <0.001 μg g(-1) at 750, 350 and 185 g a.i. ha(-1) treatments, respectively.
在田间条件下研究了鹰嘴豆（Cicer arietinum L.）土壤中 0-110 天的扑草净消失情况和植物样品中的最终残留情况。扑草净作为冬季鹰嘴豆作物的芽前除草剂，用量分别为 750、350 和 180 g ai/ha。扑草净在鹰嘴豆田间土壤条件下的消解符合一级动力学，所有剂量的半衰期平均为 11.23 天。在植物样品中发现了低浓度的扑草净残留。在 750、350 和 185 g ai/ha 处理下，分别在谷物中发现了 0.025、0.015 和 <0.001μg/g 的扑草净残留。在秸秆中发现的扑草净残留量要低得多，分别为 0.015 至 <0.001μg/g，在 750、350 和 185 g ai/ha 处理下。
