About PAPAS

Sharing support. Finding solutions.

The mission of PAPAS is to develop a systems approach to control plant-parasitic nematodes that threaten the potato industry in the United States.

Our Goals

  • Provide decision support tools to growers and industry members affected by nematode infestations.
  • Accelerate the development of potato varieties with nematode resistance through plant defense genes.
  • Attain compounds toxic to potato nematodes from the plant species, Solanum sisymbriifolium, or other toxic compounds for novel nematicide production.
  • Deliver information and research results to potato growers and industry stakeholders for adoption within integrated systems approaches for effective nematode management.
