Domestic quarantine regulations are legal restrictions imposed to prevent the spread of localized pests and pathogens from infested regions of a country to uninfested areas.
Step 2: Detailed Explanation:
In India, the Golden Nematode or Potato Cyst Nematode, {Globodera rostochiensis, is confined primarily to the Nilgiri and Kodaikanal hills of Tamil Nadu.
