Title: 2,4-Dichlorophenoxyacetic acid (2,4-D)–resistant crops and the potential for evolution of 2,4-D–resistant weeds
Abstract: In their recent article, we feel that Wright et al. ( 1) misrepresented the potential for 2,4-dichlorophenoxyacetic acid (2,4-D)–resistant weeds in 2,4-D–resistant cropping systems and exaggerated the sustainability of their approach to addressing glyphosate-resistant weed problems in agriculture. Wright et al. ( 1) announced the development by Dow AgroSciences of transgenes in corn, soybean, and cotton that will confer metabolic resistance in these crops to the herbicide 2,4-D. They promoted this technology as a solution to the epidemic of glyphosate-resistant weeds caused by overuse of the herbicide glyphosate in glyphosate-resistant crops. In addressing the obvious criticism that their technology will enable a similar overuse of 2,4-D .
