OMRI Listed Multi-Strain Trichoderma Inoculant

What a Trichoderma inoculant is and how it works in soil

Multi-Tricho is a high-CFU, OMRI Listed Trichoderma inoculant: a living powder of beneficial soil fungi you dissolve in water and apply to the root zone. Once it is down, the fungi colonize root surfaces and the surrounding rhizosphere and work on two fronts. They release cellulase, amylase, protease and related enzymes that break down crop residue and free up nitrogen, phosphorus and micronutrients the crop can take back up. And as living fungi they colonize aggressively and compete for the space and food in the root zone, establishing first so the crop grows into an occupied, biologically active root zone instead of a bare one. That head start is what shows up later as stronger roots, better establishment and more yield.

Trichoderma harzianum, asperellum and longibrachiatum: the multi-strain advantage

Multi-Tricho is built on three complementary species rather than one: Trichoderma harzianum, Trichoderma asperellum and Trichoderma longibrachiatum. Trichoderma harzianum is the most studied of the beneficial Trichoderma fungi, valued for aggressive root colonization and strong residue breakdown. Pairing it with asperellum and longibrachiatum widens the range of crops, soil types and temperatures the blend performs in, because each species occupies a slightly different niche in the root zone. That is what lets one Trichoderma for plants deliver on hydroponic transplants, marginal field soil and turf alike, and in a side-by-side trial it is what put Multi-Tricho ahead of a leading single-strain commercial product.

What the field and lab trials show

The proof is measured, not asserted, and it comes from separate trials rather than one flattering test. In an independent Arizona laboratory, peppers grown in a standing hydroponic lot reached 100% transplant survival, 24 of 24 plants, against 71% for the untreated control on the same nutrient solution, and built about 39% more wet root mass, 126.4 grams versus 91.1 grams, with roots nearly twice as long. In a separate drip lot run out to fruiting, treated plants set about 18% more peppers per plant, 42.6 versus 36.2, and stood roughly 35 centimeters taller. In a third soil lot, Multi-Tricho also finished ahead of a leading commercial Trichoderma product on height and leaf mass. These are three separate lots in separate systems, not one experiment measured three ways, and the trial did not run replication statistics, which is exactly why we show the plant counts.

Is Trichoderma a fungicide?

No. Multi-Tricho is a soil and root inoculant and biostimulant, not a registered fungicide, and it makes no disease-control claims. What it does is colonize the root zone aggressively and compete for space and resources, which helps crowd out less desirable organisms and keeps roots vigorous. Growers searching for a biofungicide are usually after that competitive, root-zone effect, and that is what a multi-strain Trichoderma inoculant delivers, through ecology rather than chemistry.

Roots, transplant survival and yield

A crop is decided early. Every transplant lost in the first weeks is a hole in the stand that produces nothing for the rest of the season, and root establishment sets the ceiling on everything after it. By colonizing the root zone the moment it goes in, Multi-Tricho drives root elongation and branching for better anchorage and nutrient uptake, which is what carried the Arizona peppers from 71% survival to 100% and from 91.1 to 126.4 grams of root mass. Stronger, longer roots reach water and nutrient a stressed seedling otherwise cannot, and that early advantage is what turned into more fruit per plant at harvest.

Faster turf and grass establishment

Turf is judged on how fast and how evenly it comes in. In a Mustang III turfgrass trial in Colombia, plots treated weekly with Multi-Tricho reached 100% germination by day 9, against 22% for the untreated control on the same nutrient solution, and grew 30% taller by day 24, 9.2 centimeters versus 7.1. The response tracked the rate at every reading: more inoculant, faster and more even establishment. For sod producers, golf course superintendents and anyone overseeding into a thin stand, that shorter, more uniform establishment window is where a turf inoculant pays.

Soil health, residue breakdown and composting

As a microbial soil amendment, Multi-Tricho rebuilds root-zone biology rather than feeding the crop once. Its cellulase, amylase and protease activity breaks down crop residue and organic matter, which is the same enzyme work that makes it an effective Trichoderma compost inoculant: dissolve the powder, spray the piles and turn them to distribute it through the windrow. In the field, that residue turnover returns nutrients to the root zone and supports soil aggregation for better aeration and water movement, so fertility builds over repeat applications instead of fading like a one-time input.

Crops and systems 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 live or die on strong early roots.
• Orchards and vineyards: better root-zone biology and long-term soil fertility in perennial ground.
• Greenhouse and hydroponic crops: reliable root development in controlled and soilless systems.
• Turf and forage: quicker, more uniform germination and early growth, as in the Mustang III trial.
• Organic and regenerative systems: OMRI Listed and compatible with living-soil programs.

Trichoderma under stress and in degraded or regenerative soils

The clearest test of a soil biology input is what happens on poor ground. In a China green pepper trial on deliberately poor soil with no fertilizer applied at all, treated plants produced 156 grams of fruit per plant against 63 grams for the untreated control, more than double the yield from soil biology alone. By colonizing and stabilizing the root zone, Multi-Tricho helps crops hold up through drought, salinity and compacted or degraded soils, and it helps rebuild that ground over time by restoring biological activity and root regeneration. For a grower on marginal or organic land, that is the point: the yield came from biology, not a bigger fertilizer bill.

Application rates and how to use the powder

Multi-Tricho is a water-soluble powder. Dissolve it fully in non-chlorinated water and apply to the root zone 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 at 50 to 100 grams per acre during vegetative growth. Keep the solution agitated, apply as close to the roots as possible, and flush the lines afterward. Full rates, timing and the seed-treatment and composting doses are in the application section below.

Using Multi-Tricho with fertilizers, compost teas and other biologicals

Multi-Tricho integrates with compost, organic inputs and conventional fertilizer programs, and it can go out with water or compost teas. Dilute fertilizer fully in water before adding the microbes. Do not tank-mix it with fungicides, chlorinated water or other pesticides, which reduce microbial viability; where a chemical program is required, separate the applications rather than mixing them in the same tank.

OMRI Listed and organic production

Multi-Tricho is OMRI Listed for use in certified organic systems and meets the USDA National Organic Program requirements for microbial soil amendments, so it drops into organic and regenerative programs without a paperwork problem. It contains only naturally occurring, non-pathogenic Trichoderma fungi and is safe for organic, regenerative and conventional systems when applied as directed.

Specifications, storage and handling

Multi-Tricho is a high-CFU powder at 15 billion CFU per gram, built on Trichoderma harzianum, Trichoderma asperellum and Trichoderma longibrachiatum, and it passes a 100-mesh sieve so it moves through drip and fertigation lines without clogging. It ships in 22 lb (10 kg) and 44 lb (20 kg) pails and 340 lb (155 kg) drums, with custom concentrations and packaging available. Store it cool, dry and out of direct sunlight, and reseal the container after each use. Full specifications and shelf life are in the technical data below.

Trichoderma, Mycorrhizae or Sunrise: which one you need

The three biologicals do different jobs and are often run together. Multi-Tricho is the Trichoderma play for root colonization, residue breakdown and fast establishment. Mycorrhizae builds a longer-term symbiosis that extends the root system's reach for phosphorus and water. Sunrise is the broad multi-strain biofertilizer that pairs bacteria and fungi to unlock nutrients across the program. If you are choosing one to start, match it to the problem: establishment and residue, Trichoderma; nutrient and water reach, Mycorrhizae; overall soil fertility, Sunrise.
