Biodiversity as a tool to manage weeds

Weed management is a challenging issue in the context of pesticide reduction. Scientists Petit et al. recently reviewed several options for the biological regulation of arable weeds: weed – (cover) crop competition, weed seed granivory by invertebrates and weed interactions with pathogenic fungi. However, the understanding of these biodiversity-based options and their performance in weed biocontrol requires the implementation of farm-scale experimental trials in future.
