Trianum-G

Trianum-G Biofungicide for the reduction of soil-borne diseases Trichoderma harzianum T-22

Use Trianum-G for:

Trianum-G is a biofungicide and used for the reduction of soil-borne diseases such as Pythium spp., Rhizoctonia spp., Fusarium spp. and Sclerotinia. In addition, Trianum-G contains properties that promote plant growth, especially when it comes to the development of roots and aerial parts of the plant.

Packaging:

Trianum-G is sold in various packages that vary per country; 250 gr, 500 gr, 5 kg and 20 kg.
Formulation: Granule (GR
Concentration: 1 % w/w Trichoderma harzianum, strain T-22 spores (1,5 x 108 spores/g) and 99 % w/w inert ingredients

General information

When to use Trianum-G?

Trianum-G increases the resistance of plants against stresses that may be caused by diseases, sub-optimal feeding, watering regimes, and climatic conditions. Further, Trianum-G helps to increase a plant's nutrients uptake. This uptake in nutrients can help a plant in growth, development of roots and above-ground parts.

How does Trianum-G work?

Trianum contains spores of the beneficial fungus Trichoderma harzianum strain T-22. When Trianum is applied correctly, the plant develops mycelia, which grows along the roots and protects the roots of the crop against diseases such as:

  • Fusarium
  • Pythium
  • Rhizoctonia
  • Sclerotinia

Trianum works on the basis of the following mechanisms:

1. Competition for space
Trianum grows faster on the surface of the root than other soil-borne fungi. Other fungi have no chance to establish themselves on the roots.

2. Competition for nutrients
Trianum takes away the source of nutrients that the pathogens need to feed on. They therefore have no chance to develop.

3. Parasitism of pathogens
Trianum grows around the mycelia of the pathogen. The cell walls break down and the pathogen dies.

4. Strengthening of the plant
Trianum improves the root system through the formation of more root hairs, so that water and nutrients can be absorbed better. This leads to better yields of a stronger and more uniform crop. The difference is particularly notable when the plant is under stress and/or cultivated under less than optimum growing conditions.

5. Induced resistance
Trianum also reinforces the defense mechanism of the parts of the plant above ground (when fighting botrytis for instance), the so-called induced systemic resistance (ISR).

6. Absorption of fixed and non-fixed nutrients
Nutritional elements such as certain trace elements and phosphates are sometimes fixed in the soil. Therefore, cannot be absorbed by the plant. This particularly happens in soil with a higher level of acidity (i.e. with a lower pH). Phosphates often form compounds with calcium, iron or other trace elements. As a result they are no longer soluble.

Trianum has the capacity to make certain “fixed” nutrients available for the plant to absorb. Certain elements, such as manganese, are essential for the plant to fight diseases. Manganese is important for the natural defenses of the plant against diseases.

Trianum produces certain substances which, amongst other effects, change iron from Fe3+ into Fe2+, making it possible for the plant to absorb it.

How to use Trianum-G

Application Trianum-G

Trianum-G mixes easily with potting compost or can be dispersed mechanically over the soil/furrow using a granule spreader.

Mixing with potting compost:

Trianum can be added to the compost mix on site or delivered pre-mixed by a specialist growing media company. This second option has the following advantages:

  • Labor-saving
  • Optimum distribution of Trichoderma spores in the potting compost

Dispersing on the soil or in furrow by granule spreader:

  • Make sure the Trianum-G is distributed evenly 
  • Apply the Trianum-G granules close to the seeds or roots. Trianum-G granules are small (300-700 micron). For that reason it is advised to apply them as close to the seeds or soil as possible to limit wind influence (blowing away of the granules)
  • Make sure that the Trianum-G granules flow smoothly through the tube system of the granulators (avoid curves in the tubes)

Best working conditions Trianum-G

Use Trianum-G as a preventive method. To achieve optimal results, start using Trianum-G at the beginning of the crop cycle, preferably during sowing, cutting or planting. Trianum-G performs well under different environmental conditions. It grows in various climates (10-34°C/50-93.2°F), at a pH between 4-8, in many types of cultivation media and on the roots of many different types of crops.
