Soil Health

When You Want More

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.

Farmer vs. Soil Borne Disease

A healthy diversity and population of soil microorganisms in the root zone promote plant health and crop production.

Farming is a practice that alters native biodiversity. Repeatedly planting the same crop selects for weeds, insects, fungi, and soil microbes. Soil borne disease – fungal and bacterial – as well as certain repetitive management practices further reduces soil microbe diversity.

TriClor Benefits


Promotes native beneficial soil micro-organisms.

Supports growth of a healthy root system.

Improves water and nutrient-use efficiency.

Results in thriving plants with less crop stress.

Increases marketable crop yields.

Farmers Have Always Farmed Disease As Well As The Crop
Practical application of scientific knowledge tries to put the edge to the crop. When the beneficial soil microbes are depleted or missing from the soil, there are…

Increased plant disease and soil pathogens.

Decreased availability of nutrients to the plant.

Decreased soil structure from lower soil aggregation

Increased water requirements and loss of water holding capacity.

Loss of yield due to tired soil and plant stress.

Sustainable Farming

Over 50 years of use have proven Chloropicrin’s track record of suppressing disease and improving sustainable crop production. New studies with Michigan State University, Oregon State University, and the Research and Development Institute for the Agri-Environment in Quebec are confirming that Chloropicrin acts as a selective agent, supporting the repopulation of native, beneficial microbes.
