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.

Soil Fumigation promotes a healthy root system for potatoes, onions, carrots, strawberries, melons, nuts, grapes, cucumbers, tomatoes, tree fruit, peppers, eggplants, flowers, nurseries and more. Soil fumigation provides benefits to both consumer and grower.

Grafted watermelons are a powerful solution for growers looking to boost yields while possibly reducing plant population.
