SUMMARY The effect of 3,5‐dichlorophenoxyacetic acid (3,5‐D) in reducing the shoot growth of tomoato plants has been investigated and evidence is presented which suggests that the inhibition of shoot growth which occurs is not the result of a competitive antagonism between 3,5‐D and endogenous auxin or gibberellins. A reinvestigation of the effect of 3,5‐D on certain auxin‐induced responses failed to reveal evidence which would support the previous classification of 3,5‐D as an ‘anti‐auxin’.
