Plant growth-promoting bacteria
A plant-growth-promoting rhizobacteria (PGPR) consortium of Bacillus subtilis, Pseudomonas fluorescens, Bacillus megaterium (phosphate-solubilizing), and Azospirillum brasilense that builds root systems, unlocks bound soil phosphorus and potassium, and improves drought and salinity tolerance.
Phosphate- and potassium-solubilizing strains release nutrients already locked in the soil; auxin (IAA) production drives root proliferation for better water and nutrient capture; ACC-deaminase activity buffers drought and salinity stress; associative diazotrophs add a modest nitrogen contribution.
Stronger roots. More available phosphorus. Tougher crops.
Vigor™ is the PGPR layer of the program. It does not form nitrogen-fixing nodules itself (that is Nodu™’s rhizobial symbiosis), but it unlocks bound soil phosphorus, drives root growth, and buffers drought and salinity stress.
Bacillus subtilis (root colonization), Pseudomonas fluorescens (phosphate solubilization & biocontrol), Bacillus megaterium (phosphate solubilization), and Azospirillum brasilense (Ab-V5 / Ab-V6-type; auxin + ACC-deaminase for stress tolerance). PGPR are not host-specific: one broad-spectrum formula serves all eight legumes (no crop-specific SKU).

Select the product edition and supporting information for the intended crop. Crop profiles connect the biological components with field observations and the relevant technical documents.
At sowing: seed treatment 4–6 g/kg, in-furrow liquid 1–3 L/ha, or granule blended with starter fertilizer. For all eight legumes; co-applies with Nodu™ (nitrogen) and Orvan™ (coupling).
Select the product and application programme for the crop, growing conditions and applicable market label.
Identity-verified (16S / WGS), purity-tested, batch CFU certification, per-formulation SDS; naturally isolated, non-GMO.
CFU guaranteed to expiry; 6–8 month shelf life (form-dependent). Non-GMO, naturally isolated.
6–8 months at 5–25 °C
