Nematode management in potatoes (Irish or white)

Plant-parasitic nematodes are a major pest on potatoes in Florida.  Root-knot, sting, and stubby-root nematodes are the primary problems.  Sampling is an important component of confirming nematode problems in a field.  Nematode management relies heavily on chemical control (nematicides), but crop rotation and soil culture are important considerations as well.
