ABSTRACT
The management problem for herbicide resistance differs in several respects from the other types of resistance. This chapter discusses the issues relating to the phase when farmers are considering adoption of changed farming practices, either to delay the onset of resistance or to deal with its arrival. It reviews the key factors affecting the speed and nature of farmers’ responses to possible changed management practices and discusses the implications of this information for adoption of management practices for herbicide resistance. The chapter highlights a detailed bioeconomic model to examine herbicide resistance in the context of a complex mixed farming system. It examines the impact of resistance on the profitability of farming in a case study, and discusses the changes in farm management that resistance requires or encourages. The chapter also examines the policy implications of herbicide resistance. It highlights the implications of the modeling results for farmer decision making.
