SUMMARY The herbicide 3,5‐diiodo‐4‐hydroxyphenylmethylsulphone (ioxysone) is shown to be absorbed by the roots of dwarf bean ( Phaseolus vulgaris ) and readily translocated. No evidence was obtained that iodide becomes released from the herbicide within the plant. This behaviour is discussed and contrasted with that of the corresponding nitrile (ioxynil), a widely used contact herbicide which is not readily translocated in the plant and whose mode of action is different from that of ioxysone.
