Metabolic fate of [¹⁴C]diuron and [¹⁴C]linuron in wheat (Triticum aestivum) and radish (Raphanus sativus).

Metabolism of xenobiotics in plants usually occurs in three phases, phase I (primary metabolism), phase II (conjugation processes), and phase III (storage). The uptake and metabolism of [(14)C]diuron and [(14)C]linuron were investigated in wheat and radish. Seeds were sown in quartz sand and irrigated with a nutrient solution of either radioactive herbicide.
