Nematodes Cost California Growers Millions

California’s specialty crops face major pressure from plant parasitic nematodes (PPN) attacking roots underground.

Top offenders include root-knot, lesion, ring, cyst, and dagger nematodes, all capable of stunting plant growth and reducing yields.

Plant parasitic nematodes cost California growers millions each year by damaging the roots of:

  • Almonds
  • Grapes
  • Citrus
  • lVegetables
  • Strawberries

Early detection = smarter decisions.


TriCal was founded in 1961 by three young men – Richard Storkan, Jerry Hanes, and Robert McCaslin – who were on a mission to carry out commercial soil fumigation by specialized methods.


Trical Inc.
"We are farm consultants, helping growers to get the greatest return on investment for their crop while helping them navigate the regulations and use requirements. We are custom applicators so we have hands-on, direct field experience. We provide field support and technicians. Just like my father (TriCal Co-Founder & President) said in 1963, 'we have proved the worth of these methods.' We work hand in hand with growers so they can reap the benefits."

- Dean Storkan, TriCal President
