In Canada, the use and sale of 2,4,5-T was prohibited after 1985. [5] The international trade of 2,4,5-T is restricted by the Rotterdam Convention. 2,4,5-T has since largely been replaced by dicamba and triclopyr. Human health effects from 2,4,5-T at low environmental doses or at biomonitored levels from low environmental exposures are unknown.
