Summary:The uptake of 2,4,5‐T by spines of gorse (Ulex europaeusL.) was limited and not enhanced when picloram was added to the application solution. Translocation of 2,4,5‐T in 6‐month‐old cuttings after treatment of a single spine or lateral branch was poor. The most significant accumulation of translocated herbicide occurred in stem tissue, with lesser amounts detected in root tissues, root nodules, stem apices and flowers. Untreated lateral branches or spines accumulated minimal amounts of herbicide. The pattern and extent of distribution of 2,4,5‐T was not increased by addition of picloram. The lack of efficient control of gorse by 2,4,5‐T can largely be attributed to its inadequate uptake and lack of true systemic tr
