Mecoprop

Mecoprop (also known as methylchlorophenoxypropionic acid and MCPP) is a common general use herbicide found in many household weed killers and 'weed-and-feed' type lawn fertilizers. It is primarily used to control broadleaf weeds. It is often used in combination with other chemically related herbicides such as 2,4-D, dicamba, and MCPA.

The United States Environmental Protection Agency has classified mecoprop as toxicity class III - slightly toxic. Mecoprop is a mixture of two stereoisomers, with the (R)-(+)-enantiomer ('Mecoprop-P', 'Duplosan KV') possessing the herbicidal activity.
