What are the major impediments to resistance management for crops in the social sciences and governance?

Agriculture worldwide faces challenges in developing and managing resistance to GE-based insect and weed control strategies. Pesticide resistance has been investigated for many years, and while the fundamentals of the genetic mechanisms and management theory are well understood, at the field level resistance management has been much more effective in preventing rapid development of pesticide resistance among insects than in than in preventing herbicide resistance among weeds. Changing tactics has been a key to insect resistance managemen
