"2,4-Dichlorophenoxyacetic acid (2,4-D)–resistant crops and the potential for evolution of 2,4-D–resistant weeds." - GreenMedInfo Summary

Excerpt: "The global spread of herbicide-resistant weeds is a serious problem requiring a serious rethinking of our approach to weed management. Given that resistant weeds are the direct result of herbicide overuse, the problem will not be resolved simply by adding new herbicide-resistance traits into our crops. Rather, integrated weed management (IWM) approaches that incorporate a diversity of chemical and nonchemical practices and effectively reduce reliance on herbicides offer the promise of a truly robust weed-control system."
