| Descripción: | Introduction. The perception that native vegetation in crop fields are plants that do not contribute to production in cropping systems, and therefore must be eliminated in their entirety, has caused multiple agronomic, environmental, and social problems in agroecosystems around the world, such as selection of herbicide-resistant plants, contamination of water bodies, loss of biodiversity, increase in pest insect populations, and impact on the health of agricultural workers due to the intensive use of herbicides. Objective. To provide basic information on the origin of weeds in agriculture, the biological characteristics that make them harmful to human activities, and their ecological functions in the agroecosystem, as well as to propose the application of the concept of functional biodiversity for the agroecological management of weeds in crop fields. Development. At this time of change towards agricultural production with less use of pesticides, weed management continues to be a great challenge. To ensure that integrated weed management advances towards agroecological strategies that allow a reduction in the use of herbicides, it is necessary to promote the beneficial biotic interactions that naturally regulate weeds. The study and application of functional biodiversity in agroecosystems then emerges as a need to manage vegetation in such a way that the negative effects of weeds on crops are minimized and the agroecosystem services of weeds are maximized. Conclusion. The differentiation between weeds and segetal vegetation as part of an agroecological management of cropping systems would make it possible to maintain a positive productivity-biodiversity balance in the agroecosystems. |
