Increased world trade has made the movement of goods and people easier and more common; with that increased movement, has come increased potential for the movement of pests. Two current exotic threats to Wisconsin (emerald ash borer, an insect pest of ash trees, and potato cyst nematode, an agricultural threat) will be examined to outline the ways in which pests may be transported to new regions, the systems in place for prevention and early detection, and the role of various players—particularly growers and crop consultants―in safeguarding Wisconsin’s agriculture and environment.
