Propachlor (2-chloro-N-isopropylacetanilide)

The preparation acts on annual grasses and on some broadleaf weeds and was briefly sold in the UK as a germination inhibitor under the name Murphy Covershield. Propachlor was sold in flake, pelletized, and concentrated liquid formulations, which contained Propachlor as the main ingredient, or as a mixture with Atrazine or Propazine. Propazine-only formulations typically included instructions for mixing with Atrazine.

Between 1987 and 1996, about 2.1 million pounds of its active ingredient were used in the United States. 75% was applied to sorghum crops and 24% to maize.

Monsanto voluntarily discontinued its manufacture in 1998. It is currently listed in the U.S. Environmental Protection Agency's Toxics Release Inventory. In 2008, the European Commission issued a decision withdrawing its approval for use as of March 18, 2009, citing the presence of its metabolites in groundwater. Propachlor was added to California's Proposition 65 list as a carcinogen in 2001.
