(Talaromyces muroii strain PS)
(Talaromyces muroii strain PS)
Mode of action: The efficacy of Talaromyces as plant growth promoter can be attributed to the production of a number of important plant hormones including gibberellins (GAs), IAA and abscisic acid. Seed treatment with Talaromyces resulted in significant increases in growth characteristics such as root length, plant height, plant fresh weight and plant dry weight. The process of P-cycling is regarded as the main direct mechanism of growth promotion.

(Trichoderma harzianum T22)
(Trichoderma harzianum T22)
Mode of action: The mechanism of growth stimulation by Trichoderma involves a multilevel root-shoot communication. The phytostimulation effect of Trichoderma applications has been attributed to several direct and indirect effects on plants, including the release of substances with auxin activity, small peptides as well as volatile organic compounds, which improve root system architecture (total root length, density and branching) and assimilation/solubilisation of macronutrients (P) and micronutrients (Fe, Mn and Zn), thus boosting plant growth and crop productivity.

Description: Fungal biofertilizer for plant growth promotion.
Special attributes: T. harzianum T22 is a rhizosphere competent strain (i.e., able to colonize and grow with root systems of most plants). When applied as a seed or soil treatment, it will colonize the entire root system of most plants and increase the depth of rooting even when plants are fully mature. This occurs across many soil types and pH levels and results in a variety of beneficial effects. Proteomic data confirmed that T. harzianum T22 increases photosynthetic and respiration rates while inducing resistance to biotic and abiotic stresses (Harman, 2015).

Live bacteria (Azotobacter species)
Live bacteria (Azotobacter species)
Mode of action: Azotobacter species are free-living bacteria known for their ability to fix nitrogen under aerobic conditions. Increase in crop production is linked to the production of plant hormones such as auxins, cytokinins and Gibberellic acid-like substances. These bacteria also produce siderophores, ammonia, ACC deaminase and indoleacetic acid which stimulate plant growth.
