Mecoprop, or methylchlorophenoxypropionic acid (MCPP), is a common general use herbicide found in many household weed killers and "weed-and-feed" type lawn fertilizers.^[3] It is primarily used to control broadleaf weeds.^[4] It is often used in combination with other chemically related herbicides such as 2,4-D, dicamba, and MCPA.

Mecoprop is a mixture of two stereoisomers, with the (R)-(+)-enantiomer ("Mecoprop-P", "Duplosan KV") possessing the herbicidal activity^[5].

The United States Environmental Protection Agency has classified mecoprop as toxicity class III - slightly toxic.^[4]
