OMRI Listed Multi-Strain Trichoderma Inoculant

Multi-strain Trichoderma inoculant for roots, yield, and soil biology

Multi-Tricho is a high-CFU, OMRI Listed Trichoderma inoculant built on three strains: Trichoderma harzianum, Trichoderma asperellum, and Trichoderma longibrachiatum. The strains colonize the root surface and the surrounding rhizosphere, where they release enzymes that break down crop residue and free up nutrients the plant can use. Together they cover a wider range of soils, crops, and conditions than any single-strain product, which is why the blend performs on everything from hydroponic transplants to marginal field soil.

How Multi-Tricho works in the soil

Once applied, the three Trichoderma strains settle on roots and in the root zone and work on two fronts. They produce cellulase, amylase, protease, and related enzymes that digest crop residue and fibrous organic matter, which speeds up nutrient cycling and returns nitrogen, phosphorus, and micronutrients to a form the crop can take up. And as living fungi, they colonize root surfaces aggressively and compete hard for the space and food in the rhizosphere, establishing first and crowding out the less desirable organisms that tend to move into a stressed, poorly colonized root zone. A root system that is already occupied by vigorous beneficial fungi is a more resilient one, and that head start is part of what drives the establishment, root, and yield results below.

What the field and lab trials show

In an independent U.S. greenhouse trial, Multi-Tricho reached 100% transplant survival, 24 of 24 plants, against 71% for the untreated control, and built about 39% more root mass, 126.4 grams versus 91.1 grams, with roots nearly twice as long. Treated plants went on to set about 18% more peppers per plant, 42.6 versus 36.2, and outgrew the untreated plants by roughly 35 centimeters. In a side-by-side lot, Multi-Tricho also outperformed the leading commercial Trichoderma product on growth and leaf mass.

In a separate field trial on deliberately poor soil with no fertilizer applied, treated green pepper plants produced 156 grams of fruit per plant against 63 grams for the control, more than double the yield from soil biology alone. In a Mustang III turfgrass trial, Multi-Tricho produced faster, more uniform germination and taller early growth than untreated turf, with a clear dose response. Real trial numbers like these are the part of the page competitors cannot copy.

Trichoderma harzianum and the multi-strain advantage

Trichoderma harzianum is the most studied of the beneficial Trichoderma fungi, valued for aggressive root colonization and strong residue breakdown. Multi-Tricho pairs it with Trichoderma asperellum and Trichoderma longibrachiatum so the blend holds up across more crops, soil types, and temperatures than a single strain would. Each strain occupies a slightly different niche in the root zone, which is what lets the same product deliver on hydroponic peppers, field soil, and turf.

Crops and where Multi-Tricho is used

Multi-Tricho is a broad-acre and specialty-crop inoculant that fits most soil, greenhouse, and hydroponic systems:

• Row crops and cereals: faster residue breakdown, stronger roots, and steadier nutrient availability.
• Vegetables and horticulture: peppers, tomatoes, and other transplants that depend on strong early roots and high transplant survival.
• Orchards and vineyards: better root-zone biology and long-term soil fertility in perennial systems.
• Greenhouse and high-value crops: reliable root development and establishment in controlled and hydroponic settings.
• Turf and forage: quicker, more uniform germination and early growth, as in the Mustang III trial.
• Compost and residue programs: a Trichoderma inoculant for composting and organic-matter turnover.
• Organic and regenerative systems: OMRI Listed for certified organic use and compatible with regenerative programs.

Soil health and root benefits

As a soil biology input, Multi-Tricho works as a microbial soil amendment that rebuilds root-zone activity rather than feeding the crop just once. It supports soil structure and aggregation for better aeration and water movement, drives root elongation and branching for stronger anchorage and nutrient uptake, and acts as a plant biostimulant and plant growth-promoting fungi inoculant (PGPF) that improves nutrient-use efficiency and helps crops hold up under drought, salinity, and compacted or degraded soils. Because it is a living inoculant, those benefits build over repeat applications instead of fading like a one-time input.

Formats, sourcing, and how to buy

Multi-Tricho is produced in the United States as a high-CFU powder and is available in bulk and wholesale, along with OEM and private-label programs for distributors, integrators, and agricultural input companies. Sourcing directly from the manufacturer means verified CFU counts, lot traceability, and consistent supply, and it is one of the most complete multi-strain Trichoderma inoculants you can buy. If you are looking for where to buy Trichoderma for plants, Multi-Tricho is for sale direct from the manufacturer: buy Trichoderma inoculant in bulk, wholesale, OEM, or private label, or request a sample or quote through the form on this page.

How to apply

Multi-Tricho goes out through drip, drench, or fertigation at 100 to 200 grams per acre, in-furrow at 25 to 50 grams per acre at planting, or as a foliar spray during vegetative growth. Full rates and timing are in the application section below. Keep it out of the tank with fungicides and other pesticides.
