Use for
Triario GR protects plants against a range of soil-borne root diseases through several different modes of action. It also improves root system development, nutrient uptake and plant growth.
Diseases
Trichoderma harzianum T-22 protects against soil-borne diseases such as Pythium spp., Rhizoctonia spp., Fusarium spp. and Sclerotinia spp.. In addition, Triario GR promotes plant growth and uniformity.
Crops
Triario GR can be used in most open field crops.
How it works
Mode of action
The mode of action of Triario GR is based on the following mechanisms:
Competition for space
Triario GR grows faster on the surface of the root than other soil-borne fungi. Other fungi get less chance to establish on the roots.
Competition for nutrients
Triario GR takes away the source of nutrients that the pathogens need. The pathogens therefore have less chance to develop.
Parasitism of pathogens
Triario GR grows around the mycelia of the pathogens. The cell walls of the pathogens break down and the pathogens die.
Strengthening of the plant
Triario GR improves the root system through the formation of more root hairs, so that water and nutrients can be taken up better. This leads to a stronger and more uniform crop and better yields. This effect is stronger when the plant is under stress and/or cultivated under less than optimum growing conditions. Triario GR also reinforces the defence mechanism of the parts of the plant above ground, the so-called induced systemic resistance (ISR). Triario GR has the capacity to make certain 'fixed' nutrients such as manganese and iron available for the plant to take up.

Directions for use
Application
Triario GR can be spread on the soil or in the furrow.
In case of mechanical application with a granule spreader, the spreader's exit hole should be as close to the soil as possible to prevent wind blowing away the small granules. Make sure that the Trianum-G granules flow smoothly through the tube system of the spreaders (avoid curves in the tubes).
Dosage
- The dosage of Triario GR depends on the crop and should always be adjusted to the particular situation. Check the label to find the recommended dosage for each crop and situation
- Application rates typically range from 10-50 kg/ha, 1-10 kg/1000 plants or 375-750 gram/m³ of growing substrate
- Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation
Timing
Apply as early as possible in the crop cycle.
Environmental conditions
Triario GR performs well under different environmental conditions. Trichoderma harzianum T-22 grows in a wide temperature range (10-34°C/50-93°F), at a pH between 4 and 8, in many types of cultivation media and on the roots of many different crops.
