Use for
Triario WG 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 WG promotes plant growth and uniformity.
Crops
Triario WG can be used in most open field crops.
How it works
Mode of action
The mode of action of Triario WG is based on the following mechanisms:
Competition for space
Triario WG 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 WG takes away the source of nutrients that the pathogens need. The pathogens therefore have less chance to develop.
Parasitism of pathogens
Triario WG grows around the mycelia of the pathogens. The cell walls of the pathogens break down and the pathogens die.
Strengthening of the plant
Triario WG 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 WG also reinforces the defence mechanism of the parts of the plant above ground, the so-called induced systemic resistance (ISR). Triario WG has the capacity to make certain 'fixed' nutrients such as manganese and iron available for the plant to take up.

Directions for use
Preparation
- Add 1 volume of Triario WG to 5 volumes of water in a bucket
- Mix thoroughly
- Add the suspension to the required amount of water to obtain the final spray, drip or drench solution
- Agitate continuously to maintain a homogeneous distribution of spores
- Apply on the day of preparing the solution, since spore quality will decrease within a few hours
Application
Triario WG can be applied via drench, drip-irrigation systems or by spraying in furrow at the time of sowing or transplanting. Apply Triario WG as early as possible to the crop for optimal effect.
Application via drench or spray:
- Triario WG can be applied with any spraying or drenching equipment
- After application clean the equipment by flushing thoroughly with water
- Use sufficient solution to guarantee good penetration in the soil
Application via drip irrigation:
- Spores in Triario WG should reach the roots quickly. Make sure that drip irrigation filters are clean (spores can attach themselves to organic material in filters).
- To increase spore attachment to the roots, avoid run-off and excess irrigation the first two days after application of the product. Triario WG is not a systemic product and is therefore not taken up by the plant.
Dosage
- The dosage of Triario WG 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 1-5 kg/ha.
- Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
Timing
Start application preventively at sowing or soon after planting of the crop.
Triario WG 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.
