{{Short description|Agricultural system}}
The '''Enlist Weed Control System''' is an [[agriculture|agricultural]] system that includes seeds for [[genetically modified crops]] that are resistant to Enlist (a broadleaf [[herbicide]] with two active agents, [[2,4-Dichlorophenoxyacetic acid]] (2,4-D) and [[glyphosate]]) and the Enlist herbicide; spraying the herbicide will kill weeds but not the resulting crop.<ref name=reuters/><ref>{{cite web
The Enlist approach was developed to replace the "Roundup-Ready" system that was introduced in 1996 by [[Monsanto]] and which has become less useful with the rise of glyphosate-resistant weeds.<ref name=reuters/>
==''Enlist Duo''==
''Enlist Duo'' is an [[herbicide]] that contains the choline form of [[2,4-Dichlorophenoxyacetic acid]] (2,4-D) and [[glyphosate]] plus an unknown number of unlisted ingredients. Dow added chemicals to the mixture in what it termed "Colex-D technology"
2,4-D is one of the most widely used herbicides in the world.<ref>von Stackelberg K. A Systematic Review of Carcinogenic Outcomes and Potential Mechanisms from Exposure to 2,4-D and MCPA in the Environment. J Toxicol. 2013;2013:371610. {{PMID
Other countries assessing the system include Brazil, Argentina and various food importing countries.<ref name=fleury>{{cite web | url=http://www.agannex.com/energy/enlist-weed-control-system-in-canada | author=Donna Fleury | title=Enlist weed control system in Canada.

==Enlist crops==
As of April 2014 maize and soybeans resistant to 2,4-D and glyphosate had been approved in Canada,<ref name=fleury/> and in September 2014 the [[USDA]] approved the same two crops.<ref name=wired>{{cite
==Criticism==
2,4-D was one of the main ingredients of [[Agent Orange]], a defoliant used during the [[Vietnam War]] that was blamed for many health problems.<ref name=NPIC2>{{cite web |title=2,4-D General Fact Sheet |url=http://npic.orst.edu/factsheets/24Dgen.html|publisher=National Pesticide Information Center |access-date=15 December 2015}}</ref> According to a Reuters article the
The [[U.S. Environmental Protection Agency]] has moved to rescind its approval due to conflicting claims from the manufacturer about synergistic effects from mixing the two herbicides. Dow had told the EPA that the combination of the two herbicides did not enhance their toxicity to plants, but an earlier [[patent application]] from Dow claimed that it did.<ref name="NPR">{{cite news |first1=Dan |last1=Charles |publisher=[[National Public Radio]] |title=Busted: EPA discovers DOW weedkiller claim; wants it off the market |url=https://www.npr.org/sections/thesalt/2015/11/25/457393114/busted-epa-discovers-dow-weedkiller-claim-wants-it-off-the-market |date=November 25, 2015 |access-date=November 25, 2015}}</ref>
