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

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.

Trident's Idaho sugar beet trial is underway with soil fumigation using CPM 65. This application is the first step in our effort to enhance sugar percentage and increase tonnage per acre. While the process is just beginning, establishing healthy soil is essential for supporting strong crop performance throughout the season.

TriCal Group works closely in collaboration with universities and researchers to protect our food supply and health. The chemicals we use are registered in varying chemical formulations for maximum performance, safety, and environmental health. All have been listed as exempt under EPA residue tolerance, meaning no resulting residue in or on food grown after soil treatment with these chemistries.
