Because strong berry seasons are built from the ground up.
Managing Plant Parasitic Nematodes in California Specialty Crops with Soil Fumigation
Dr. Kristi Sanchez addresses how plant parasitic nematodes continue to challenge growers across California, affecting the underground root systems of many high-value crops in crops such as almonds, grapes, citrus, vegetables, and strawberries.
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.

Trical Grape Field Trial (Modesta, CA): Documented Importance of Soil Fumigation
In the Fall of 2019, Dr. Kristi Sanchez began a Grape Field Trial in Modesto, CA, investigating soil fumigation methods and their impact on vineyard performance. The trial focused on assessing TriClor adoption in vineyards alongside the performance of TELONE™ II.
Field Visit for Grape Trial in Modesto, Ca. with Dr. Kristi Sanchez
It was an honor to get invited by one of our Scientists, Dr. Kristi Sanchez. It was remarkable to see her in action out in the field, doing what she does best: helping diagnose nematode issues and providing support to growers throughout the Central Valley.
Chloropicrin Shifts Soil Biology in Powerful Ways across Diverse Regions, Crops, and Soil Types
What the studies conclusively show is that in the weeks and months following soil fumigation with chloropicrin, soil microbial communities (bacteria and fungi) shifted in remarkable and quantifiable ways.
Fertigation in Substrate: Doing it Right? for Berries
Change occurs slowly in a traditional soil production system. This allows berry growers to make fertigation mistakes that are not completely detrimental. Soil deficiencies are more difficult to correct. When fertigating in a substrate system, growers can change pH almost daily.
Growing Greater Grapes Pt. 2 – Modesto Trial Results
TriClor and TELONE™ fumigant treatments continue to demonstrate significant reduction in total plant-parasitic nematode (PPN) density across all 3 seasons compared to untreated control, shown in the graphic below.
Growing Greater Grapes – Modesto Trial Update
By utilizing pre-plant fumigants in a vineyard – such as TriClor (Chloropicrin) and TELONE™ II (1,3-Dichloropropene) – growers can reduce the total parasitic nematode pressure within the soil where the grapes are being planted.
