Since its discovery and initial commercialization in the 1940s, 2,4-D has been an important tool for weed control in a wide variety of crop and noncrop uses. Work studying its chemistry, physiology, mode of action, toxicology, environmental behavior, and efficacy has not only helped elucidate the characteristics of 2,4-D but also provided basic methods that have been used to investigate the properties of hundreds of herbicides that followed it. Much of the information published by researchers over 60 yr ago is still pertinent to understanding the performance of 2,4-D today. Further, new studies continue to be published, especially regarding the mechanisms of 2,4-D action at the molecular level. New uses for 2,4-D, sometimes enabled by biotechnology, continue to be developed. This review strives to provide an overall understanding of 2,4-D activity in plants, plant sensitivity to 2,4-D, toxicological impacts, and current and future uses.

Desde su descubrimiento y su comercialización inicial en los años 1940s, el 2,4-D ha sido una herramienta importante para el control de malezas en una amplia variedad de cultivos y para usos no agrícolas. Trabajos estudiando su química, fisiología, modo de acción, toxicología, comportamiento en el ambiente, y eficacia han ayudado no solamente a elucidar las características del 2,4-D, pero también han brindado métodos básicos que han sido usados para investigar las propiedades de cientos de herbicidas que lo han seguido. La mayoría de la información publicada por investigadores durante los últimos 60 años es todavía pertinente para el entendimiento del desempeño de 2,4-D, hoy en día. Además, nuevos estudios continúan siendo publicados, especialmente en relación a los mecanismos de acción del 2,4-D a nivel molecular. Nuevos usos para el 2,4-D, algunas veces producto de la biotecnología, continúan siendo desarrollados. Esta revisión busca brindar un entendimiento general de la actividad de 2,4-D en las plantas, la sensibilidad de las plantas al 2,4-D, los impactos toxicológicos, y sus usos presentes y futuros.
