Control rather than eradicate weeds

The intensive use of herbicides and tillage to eradicate weeds from fields leads over time to biodiversity loss, soil erosion, health risks, and herbicide resistance. In a recent review, researchers MacLaren et al. suggest to regulate rather than eradicate weeds, in order to suppress problematic weeds while fostering weed diversity, able to sustain ecosystem services. This could be achieved by reducing the intensity of weed control, but increasing the strategic use of the crop, livestock, nutrient, and management diversity on farms.
