Integrated weed management: Tools and strategies in a world of pesticide restriction

Herbicides have been the dominant tool for weed management in agricultural crops, horticulture, and amenity turfgrass. Because of the selection pressure exerted by herbicide use due to their incredible effectiveness, weed species communities changed to more tolerant species, and individual species evolved to resist herbicide modes of action. Sustainable weed management must take a lesson from the impacts of herbicides on weed communities and species. Future strategies must be more dynamic and integrated, creating instability in weed communitiesand increasing the number and diversity of practices affecting weeds. This special issue of the Italian Journal of Agronomy, entitled: "Integrated weed management: Tools and strategies in a world of pesticide restriction" collects 11 articles presenting innovative ideas and research to foster increased sustainable management practices.
