Dissipation of pendimethalin in the soil of field peas (Pisum sativum L.) at 0 to 110 days, and terminal residues in green and mature pea were studied under field conditions. Pendimethalin was applied as pre-emergence herbicide at 750, to 185 g a.i. ha(-1) in winter, in field peas. Dissipation of pendimethalin in the soil at 0 to 110 days followed first-order kinetics showing a half-life of 19.83 days averaged over all doses. Low pendimethalin residues were found in mature pea grain (0.004, 0.003, <0.001 μg g(-1)), and straw (0.007, 0.002, <0.001 μg g(-1)) at 750, 350 and 185 g a.i. ha(-1) treatments, respectively. The study indicated that residues of pendimethalin in green and mature pea were within the prescribed MRL limits.
在田间条件下研究了冬播豌豆（Pisum sativum L.）土壤中 0 至 110 天的二甲戊灵消解情况，以及青豌豆和成熟豌豆中的最终残留情况。在豌豆田中，以 750 至 185 g a.i. ha(-1) 的剂量进行了芽前除草施药，将二甲戊灵作为除草剂使用。土壤中二甲戊灵在 0 至 110 天内的消解遵循一级动力学，所有剂量的平均半衰期为 19.83 天。在 750、350 和 185 g a.i. ha(-1)处理下，在成熟豌豆籽粒（0.004、0.003、<0.001μg g(-1))和秸秆（0.007、0.002、<0.001μg g(-1))中均发现低浓度的二甲戊灵残留。该研究表明，青豌豆和成熟豌豆中的二甲戊灵残留量均在规定的最大残留限量范围内。
