title: Dissipation of pendimethalin in the soil of field pea (Pisum sativum L.) and detection of terminal residues in plants.
abstract: 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.
