Biofungicide
Triva is a biofungicide based on Trichoderma harzianum strain T-22 for the biological protection of developing roots. The documented scope of this strain covers root diseases in vegetable, berry and other crop systems.
T-22 associates with roots as they develop. This places the strain within a preventive root-zone strategy, where root growth and the condition of the surrounding soil or substrate are considered together.
T-22 competes with soilborne pathogens for space and nutrients. This explains a biological protective role at the root interface, with performance depending on the particular formulation and growing environment.
The documented scope of T-22 covers root pathogens in Pythium, Rhizoctonia and Fusarium; granular formulations also cover Sclerotinia. Each scope belongs to a specific formulation, and a pathogen genus does not establish activity against every species or specialised form.
The biological identity is Trichoderma harzianum Rifai strain T-22 (also designated KRL-AG2). The strain designation connects the organism to its supporting documents; the species name alone does not define the same disease spectrum.
T-22 biological fungicides contain living fungal spores. Biological activity is therefore described through organism identity and viable activity, together with the physical properties of the formulation.
The wettable-powder format combines the biological component with formulation materials that support wetting and dispersion. Carrier composition and biological content are separate specification fields. Water-dispersible granules have their own formulation records.

T-22 · Preventive root protection against Pythium, Rhizoctonia and Fusarium. Genus-level data do not establish control of every wilt disease.
Choose the product and application programme to suit the crop, growing conditions and the label that applies in your market.
A technical specification should connect the T-22 or KRL-AG2 identity with the batch record and supporting formulation documents. Single-strain material and multi-strain formulations require separate identification.
Read the declared viable activity with its analytical method, unit and point in product life. A release result and an end-of-shelf-life specification describe different conditions and should remain identifiable in the technical record.
Wetting, dispersion, suspension behaviour and packaging condition complement biological quality. Storage and compatibility information should correspond to the exact powder formulation and its documented shelf life.
No. The documented uses of single-strain T-22 cover named root diseases. They do not establish Phytophthora control, and a genus-level Fusarium root claim does not establish control of a specific vascular-wilt pathogen.
The strain and formulation composition matter. A single-strain T-22 record describes that biological material and use context; a mixture containing other organisms requires its own supporting evidence.
