Diseases
Trichoderma harzianum T-22 protects against soil-borne diseases such as Pythium spp., Rhizoctonia spp., Fusarium spp. and Sclerotinia spp. In addition, Trianum-G promotes plant growth and uniformity.
Mode of action
The mode of action of Trianum-G is based on the following mechanisms:
Competition for space
Trianum-G 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
Trianum-G takes away the source of nutrients that the pathogens need. The pathogens therefore have less chance to develop.
Parasitism of pathogens
Trianum-G grows around the mycelia of the pathogens. The cell walls of the pathogens break down and the pathogens die.
Strengthening of the plant
Trianum-G 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. Trianum-G also reinforces the defence mechanism of the parts of the plant above ground, the so-called induced systemic resistance (ISR). Trianum-G has the capacity to make certain 'fixed' nutrients such as manganese and iron available for the plant to take up.
