Summary. Treatment of aspen ( Populus tremula L.) with 2,4‐dichlorophenoxyacetic acid (2,4‐D), using a leaf spray, basal bark spray or a stem injection method of application, resulted in some reduction of stump regrowth although downward translocation of 2,4‐D was slight. Persistence of 2,4‐D in dead leaf tissue and in woody tissue near the injection sites was observed. This persistence could in certain circumstances be noted 6 years after treatment.
