T34 Biocontrol® Application Methods

Application Versatility

One Product, Multiple Application Pathways: Seedling Trays, Soil, and Foliar

The versatility of T34 Biocontrol® is not just a matter of formulation, but also of where the microorganism can establish itself and act. Trichoderma asperellum strain T34 colonizes both the rhizosphere and the leaf surface, and this ability opens up three application areas that cover the entire crop cycle: the seedling tray, the soil, and the aerial part of the plant.

In the seedling tray, the product is incorporated into the substrate during preparation or sprayed onto the tray. The plant develops in an already-colonized medium and reaches transplant with the rhizosphere occupied and protected.

In the soil, the application accompanies the crop from planting through the end of the cycle. Root dipping allows for a targeted treatment at the time of transplant, using very small product volumes. Irrigation then delivers T34 Biocontrol® through the system the operation already uses, in both soil-based and hydroponic/soilless systems, maintaining adequate population levels whenever the crop requires it.

In foliar application, the product is diluted and sprayed onto the aerial part of the crop. Here the criterion is not a fixed schedule but timing relative to disease pressure: early application — at the onset of favorable environmental conditions or during the early stages of pathogen development — is what allows the leaf surface to be occupied before pathogen pressure increases. Authorization depends on the national registration in effect in each country.

None of the three application areas requires specialized equipment or an added task on the work calendar: all of them rely on operations the farm already performs regularly, from filling trays to irrigation and routine foliar treatments. This is the practical reason a single product fits contexts as different as a professional nursery, a hydroponic greenhouse, or an open-field planting.
