Cultural management options for herbicide resistant weeds

Abstract

Heavy reliance on herbicides for in-crop weed management nationally has resulted in widespread herbicide resistance. Growing competitive crops can suppress in-crop weeds and often results in reduced weed numbers and reduced weed seed production. This research involved a comprehensive and national literature review on existing crop competition studies, a meta-analysis of existing data, identified knowledge gaps and developed recommendations for future national research, including a protocol for improved research and development (R&D) for crop competition. A final report was submitted and a draft brochure was developed to promote crop competition as an effective weed management tactic.
