Up to 90% of a plant’s growth happens underground. Strong, healthy roots determine how well a crop absorbs water and nutrients—directly impacting yield, uniformity, and overall plant resilience.

That’s why investing in soil preparation early helps create the conditions crops need to grow stronger, withstand stress, and perform consistently throughout the season.

TriCal Group Companies are committed to the safe and responsible use of soil fumigation. We strive to protect you, your community and the environment. Our Companies rely on decades of experience, thousands of in-field application trials, and hundreds of university research studies to find the perfect formulation that is healthy for your crops, profitable for your farm, and safe for your community.

Successful flower crops begin below the surface. Soil fumigation helps create clean, uniform beds that support healthy root development, even growth, and consistent flowering throughout the season. By starting with the soil, growers give their flowers the best chance to thrive.

At TriCal New Zealand, healthy blooms start from the ground up.

TriCal Group works closely in collaboration with universities and researchers to protect our food supply and health.

Row by row, healthy soil supports steady vine growth, balanced plant development, and the conditions needed for consistent, quality fruit. Careful soil preparation early in the season helps set melon crops up for success long before harvest.

Even emergence and straight, healthy roots begin with well-prepared soil. Through targeted soil fumigation, growers can reduce below-ground pressures and create optimal conditions for uniform carrot growth and dependable performance in the field.

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.

Beneath each tree, the soil tells a story of seasons past, of roots finding strength, and of the growers who care for the land year after year. Healthy soil provides young trees with the foundation they need to grow straight, fruit evenly, and stand strong against challenges in the orchard. Through responsible soil fumigation practices, TriCal New Zealand helps growers protect that foundation, so each harvest reflects the care that started deep underground.

Here’s to the unseen work that makes every crisp, clean apple possible.

Soilborne challenges can impact plant vigour, crown development, and early yield. Through targeted soil fumigation practices, we help New Zealand growers maintain cleaner planting beds, healthier root systems, and more consistent fruit quality throughout the season.

TriCal Group's soil treatments contribute to soil health by both suppressing soil borne diseases and supporting the growth of native organisms that are beneficial to soil and plant growth.

Our soil fumigation process helps manage soil-borne challenges, supporting healthy establishment and strong yields season after season.

Our companies at Trical Group understand that successful crops originate from healthy soil. We are dedicated to equipping growers with dependable tools, time-tested products, and expert assistance from the ground up.

That’s what growing together looks like. These New Zealand apple trees are off to a good start when planted in soil treated with blends of 1,3 - Dichloropropene plus chloropicrin.

Replant Disease is a widespread problem in intensive tree fruit and nut growing areas. It is characterized by reduced productivity in fields repeatedly planted to the same or closely related tree fruit or nut crops. It can also occur in tree fruit and nut nurseries.

Proper Soil Fumigation with products like TriChlor™ have shown long-term efficacy in treating Replant Disease.

The use of Pic-Plus soil fumigation prior to planting keeps these plants healthy and well-prepared for the season ahead.

A broccoli trial was conducted in Levin, North Island, targeting Clubroot, one of the most challenging soilborne diseases. Using Pic-Plus soil fumigation, the trial focused on protecting soil health and supporting stronger crop establishment.

Growers often rotate crops to improve the physical characteristics of the soil and/or to suppress soil borne diseases. Soil Fumigation suppresses soil-borne diseases better than standard practices which can lead to reduced rotation length and farming your better ground more often.

Trical New Zealand is currently conducting a trial in the pine tree nursery. Trical NZ is eager to see the results as part of our ongoing work to evaluate soil health solutions for forestry crops. This research helps ensure stronger, healthier trees from the very beginning.

Start cleaning out nematodes and other soilborne diseases and you have healthier plants resisting disease and reducing topical pesticide use. Soil fumigation promotes healthier plants with stronger root systems that are better at mining nutrients.
