Aminopyralid is a selective herbicide used for control of broadleaf weeds, especially thistles and clovers. It is in the picolinic acid family of herbicides, which also includes clopyralid, picloram, triclopyr, and several less common herbicides. It was first registered for use in 2005, in the USA under the brand name "Milestone" and later under various names starting with "Grazon". In the UK it is sold under the brand names Banish, Forefront, Halcyon, Pharaoh, Pro-Banish, Runway, Synero, and Upfront.
Aminopyralid is of concern to vegetable growers, as it can enter the food chain via manure, which contains long-lasting residues of the herbicide. It affects potatoes, tomatoes, and beans, causing deformed plants, and poor or non-existent yields. Problems with manure contaminated with aminopyralid residue surfaced in the UK in June and July 2008, and, at the end of July 2008, Dow AgroSciences implemented an immediate suspension of UK sales and use of herbicides containing aminopyralid.
