Resumen:
The increase in human population has generated proportional food needs. However, agricultural productivity is constantly affected by factors decreasing land fertility. Weeds cause a constant reduction in the quantity and quality of important crops making their elimination a common necessity. During the 40's and in subsequent years, the use and constant cycling of selective chemical herbicides considerably improved crop yields. However, overuse of herbicides to minimize the impact of weeds created the development of resistant species. Since the first case in 1970, confirming the resistance of the common groundsel (Senecio vulgaris) against triazine herbicide, the number of resistant weeds against various herbicides has been considerably increasing. To date, more than 200 species have been reported to be resistant to different types of herbicides. This review aims to address the herbicide resistance mechanisms developed by weeds, which we grouped as: Changes in the uptake and translocation of herbicides; herbicide detoxification mechanisms; altered target sites and herbicide cross-resistance. © 2014 by Nova Science Publishers, Inc.
