3-(3,5-Dichlorophenoxyl)butyric acid and 2-(3,5-dichlorophenoxy)ethylamine exert pronounced dwarfing effects on tomato [Lycopersican esculentum] seedlings. Examination of extracts of the treated plants revealed the conversion of these compounds to 3,5-dichlorophenoxyacetic acid (3,5-D); the physiological activity in each case depends on such a conversion to 3,5-D within the tissues.
