Frequently Asked Questions (FAQ)

Trichoderma is a naturally occurring fungus found in soils worldwide. It has been studied extensively as a contaminant in mushroom production systems, as a component of industrial cellulase production, as well as for its plant associated biocontrol and growth promotion properties.

Trichoderma can be isolated from plants and all soil types around the world. That is, it can be free-living or it can grow endophytically (inside the plant). Among endophytic strains, some grow only in the roots while others also grow into the above ground parts of the plants.

There are many ways in which Trichoderma works with the plant including antibiosis, competitive exclusion, facilitation of nutrient absorption and uptake, and induction of plant gene expression. There is a great deal of genetic variation between strains which means that different strains may interact with plants by using some, all or even none of the above strategies. The strains that are of the most use to agriculture, influence plant gene expression to enable to plant to perform to the maximum of its genetic potential, resulting in better resistance to stress, bigger and greener plants, and increased yields. All of Agrauxine’s strains are known to work with plants in this way.

Plants can benefit from multiple Trichoderma strains because each strain is unique. That is, different strains have different genetics, which means that they possess different traits. This is the same as corn genetics: some hybrids are early maturing while others resist lodging. What underlies these different performance characters are genes. Trichoderma strains show a range of different performance characters and one may confer drought resistance whereas another may increase tillering. Inoculating plant roots with only one of these strains provides only one of these traits, however inoculating with both strains can provide an additive effect with both traits being effected. This synergy does not always occur which is why Agrauxine’s combination products are continually tested for strain compatibility and trait additivity.

Trichoderma strains with agricultural value require the presence of living plant roots. When the crop is harvested and the roots die, that season’s Trichoderma also dies. There are strains that are free-living in the soil and that do not require plant roots, however because these do not establish an endophytic, symbiotic relationship with plants, they’re of little value as agricultural biologicals.

Trichoderma can be applied as a seed treatment on farm or at the seed treater in addition to in furrow, root drench, root dip, as part of an irrigation system, and even a foliar spray. Agrauxine specializes in seed treatments, however our products are used in many different cropping systems both domestically and internationally and can often be adapted to the needs of the region and crop. Our pipeline products are being developed with these different applications in mind.

There are about 23 Trillion Trichoderma spores per acre in typical farmland. Agrauxine recommends applying its Trichoderma products at a rate about 10,000x lower than this. So, another question is, won’t the effect of the Trichoderma applied to the seed be completely washed out by the native Trichoderma in the soil? The answer to both questions is that the vast majority of the Trichoderma already present in the soil can’t form the endophytic, symbiotic relationship with the plant that our strains can and, further, the native strains generally have anagrinomically neutral (at best) interaction with plants. The difference between what is applied to the seed and what is naturally in the soil is genetics. Agrauxine has worked hard to select superior genetics that will provide consistent and excellent agronomic performance.

That’s a secret! However, it involves long term testing of candidate strains in our R&D facility, greenhouse testing, and subsequent field testing with crops of interest. A successful strain will perform at a high level in all of these situations over many environments and over many seasons. Through this process we develop strains that show enhanced performance in specific crops and these are then formulated into our crop specific products.

Graph-Ex SA® for Soybeans is an inoculant, or seed treatment, containing a specially formulated blend of Excalibre® Soybean inoculant plus SabrEx® Root Inoculant formulated in a talc-graphite carrier. Graph-Ex SA® is comprised of both proprietary beneficial bacteria (Bradyrhizobia) and beneficial fungi (Trichoderma) that provide a more efficient use of soil nutrients for the host plant

Bradyrhizobia are soil bacteria that fix nitrogen after becoming established inside root nodules of legumes. Rhizobia require a plant host; they cannot independently fix nitrogen.

At Agrauxine, our proprietary Bradyrhizobia for soybeans is specific to these crops in helping the plant to establish nitrogen fixing nodules that will convert atmospheric nitrogen to nitrogen that is useable by the plant.

The SA means that Agrauxine has also added our proprietary, patented Trichoderma strain found in SabrEx® root inoculant found to be beneficial in soybean production.

Trichoderma is a fungi that is found in soils all over the world. There are thousands of known Trichoderma strains but only a few are beneficial to plants. Trichoderma colonizes with the plants root system and develops a symbiotic relationship with the plant. The Trichoderma feed from the starches and sugars produced by the plant; while exuding beneficial enzymes and proteins for the host plant. As a result the plant produces a larger root system and improves its nitrogen and water use efficiency, thus resulting in higher yields.

Agrauxine, in working with Dr. Gary Harman of Cornell University, has developed the technology to isolate and identify specific strains of beneficial Trichoderma. Once the strains are identified and isolated, Agrauxine tests each strain, or combinations of strains, with various crops to determine which crop receives the most benefit from each strain of Trichoderma. After thorough testing, a formulation is produced and brought to market to benefit farmers.

GraphEx-SA® for Soybeans is a planter box treatment that can be added just before planting at the planter box. It consists of a talc/graphite formulation as the carrier for the Bradyrhizobia and Trichoderma. You will add 0.5 oz. of Graph-Ex SA® for Soybeans to every 140k unit of seed you add to your drill/planter. Make sure to mix Graph-Ex SA™ for Soybeans thoroughly with the seed. It should be noted; the talc/graphite formulation also helps to lubricate your planter equipment and also helps provide seed flowability. This is important as it will minimize seed hang-ups in your equipment and reduces the wear and tear on your units.

To maximize yield potential: Agrauxine recommends a double (2x) inoculant rate when planting soybeans under the following soil conditions:

1. Soil that has not hosted the specific legume for more than 3 years.
2. Soil pH of less than 5.8 or greater than 8.5
3. Organic matter less than 1%
4. Drought or flooding
5. Soil Temperatures exceeding 80°F
6. Eroded soil
7. Use of soil treatments and chemicals injurious to soil bacteria and inoculants

Yes. Using a different source of inoculant is a good choice.
