TriClor Orchard & Vineyards


Studies repeatedly show that soils fumigated with TriClor* produce healthier roots that allow the trees to establish themselves faster and more uniformly. This allows fertilizer and irrigation inputs to be utilized more efficiently, saving you time and money on the front end, and maximizing your harvest yields and profits on the back-end.


Nematode Research and Prevention with TriCal Diagnostics
/ My Ag Life Part 1: Episode 34 & Part 2: Episode 41

Jason Scott sits down with TriCal Diagnostics' Kristi Sanchez, PhD., Senior Researcher and nematologist, and Steve Koike, Director and plant pathologist, to discuss nematode research and preventative steps growers can take to identify and minimize nematode infestation.


TriClor is a chloropicrin based pre-plant soil fumigant used to manage soil-borne disease and nematodes. TriClor acts quickly to manage pathogens prior to planting and then degrades rapidly into carbon dioxide and nitrogenous compounds in the soil. These are basic nutrients that foster vigorous root and canopy growth and feed beneficial microorganisms found in the soil.

Successful farming starts from the ground up. Soil fumigation is a critical step to ensure that your orchard gets off to a good start. TriClor is a pre-plant soil fumigant and is the foundation for a successful pest management system. Targeted pathogens include soil-borne diseases and nematodes. Fumigation helps to create a healthy soil environment that allows the plant’s root system to flourish. A healthy root system leads to enhanced trunk, shoot, and canopy growth.

TriClor Manages a Broad Spectrum of Soil-Borne Disease:

  • Prunus Replant Disorder

  • Nematodes

  • Phytophthora

  • Root Rot


Unlike annual crop growers who have a chance every year to evaluate their soil health, orchard growers get one shot. TriClor can be used as a standalone or dual applied with Telone® depending on your orchard redevelopment needs. This reduces application costs while promoting early root development and improving soil health.

As an almond grower, our family has relied on soil fumigation for decades. With the ever changing restrictions, TriCal has stepped up for us and looked for viable alternatives. We really appreciate working with such an innovative company that’s willing to go the extra mile to help us solve our disease problems. TriCal has provided us with hope. I can’t imagine not working with them.
