Propachlor (2-chloro-N-isopropylacetanilide) [1] is an herbicide first marketed by Monsanto. It was registered for use in the United States during 1965. [2]
The preparation acts on annual grasses and on some broadleaf weeds [1] and was briefly sold in the UK as a germination inhibitor under the name Murphy Covershield.
Between 1987 and 1996, about 2.1 million pounds of its active ingredient were used in the United States. [3] 75% was applied to sorghum crops and 24% to maize. [3]
Monsanto voluntarily discontinued its manufacture in 1998. [4] It is currently listed in the U.S. Environmental Protection Agency's Toxics Release Inventory. [5] 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. [6] Propachlor was added to California's Proposition 65 list as a carcinogen in 2001. [7]
It is currently being produced by Makhteshim Agan Group and Shenzhen Qinfeng Pesticides Co., Ltd. [8]
