SUMMARY 3‐(3,5‐Dichlorophenoxy)butyric acid and 2‐(3,5‐dichlorophenoxy)ethylamine were both shown to exert pronounced dwarfing effects on tomato seedlings. Examination of extracts of the treated plants revealed the conversion of these compounds to 3,5‐dichlorophenoxyacetic acid (3,5‐D) and it is concluded that the physiological activity shown in each case depends on such a conversion to 3,5‐D within the tissues.
