TriCal Inc. 
New research from TriCal, Inc. is helping answer one of the biggest questions in Sweetpotato production: Can soil fumigation effectively manage root-knot nematodes while preserving soil health?
Our latest field trials near Atwater and Turlock, California, explored the impact of soil fumigation on nematode suppression, soil microbiome stability, and crop performance. The early results offer encouraging insights for growers focused on protecting yields while supporting long-term soil productivity.
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.

Teleos Ag Solutions
A smart nematode management program starts with understanding what's happening in the soil.
A recent article from PAPAS: Potatoes and Pests — Actionable Science Against Nematodes highlights the importance of developing a strategic soil sampling program.
Because nematode damage can resemble other crop problems—including drought stress and nutrient deficiencies—soil sampling can help growers identify which nematodes are present, at what population levels, and where they're located in the soil profile.
Knowing where the nematodes are in the soil helps determine how to treat the issue. Ongoing PAPAS research in Oregon and Washington has detected some nematode populations active as deep as three feet in the soil profile, reinforcing the importance of understanding where nematodes are located—not just whether they're present.
Better information leads to better management decisions. Sampling can help growers determine where treatment is warranted, support more targeted fumigation decisions, and ultimately help optimize inputs and protect ROI.
When nematode pressure warrants treatment, TELONE™ by Teleos soil fumigant helps growers manage plant-parasitic nematodes before planting, creating a zone of protection that supports healthy root establishment, crop quality, and marketable yields.
Many potato growers also use TELONE™ with chloropicrin as a complementary pre-plant approach: TELONE™ targets plant-parasitic nematodes, while chloropicrin helps manage certain soilborne diseases, including Fusarium and common scab.
Set yourself up for a successful season. Test your soil, understand your nematode pressure, and prep with TELONE™ for peace of mind.
