Abstract: Herbicide resistance is increasingly recognised as a challenge for agricultural producers worldwide. International scholarship and practical experiences suggest that collective efforts by diverse agricultural stakeholders are crucial for effective resistance management. In New Zealand, such sector-wide initiatives and strategies remain fragmented, partly due to a lack of state coordination and national extension services. This article synthesises insights from three complementary social research methods involving actors across the country’s arable-crop-growing sector (focus groups, semi-structured interviews, and an industry workshop) to identify pathways to foster collaboration and more strategic resistance management. The presented findings detail challenges, opportunities, and potential actions across four domains: strengths and weaknesses of New Zealand’s farming context, better information and knowledge exchange, improved collaboration and coordination, and targeted education and training. Our analysis highlights that most opportunities described within these domains involve purposely strengthening existing, or forming new, social and institutional relationships as part of establishing resistance management as a shared sector responsibility. A portfolio of multipronged initiatives and programmes is then required for effective whole-industry strategies. We discuss potential next steps to collectively realise identified opportunities, from more immediately feasible steps to long-term activities. These insights conceptually contribute to the international scholarship on herbicide resistance by reinforcing the notion that industry leadership and meaningful farmer involvement are indispensable for more collaborative approaches aimed at strategically managing resistance.
