Vigor™
Plant growth-promoting bacteria
A plant-growth-promoting rhizobacteria (PGPR) consortium of Bacillus subtilis, Pseudomonas fluorescens, Bacillus megaterium (phosphate-solubilising), and Azospirillum brasilense that builds root systems, unlocks bound soil phosphorus and potassium, and improves drought and salinity tolerance.

Roots & nutrient use
Biological action
Phosphate- and potassium-solubilising 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.
Agricultural purpose
Stronger roots. More available phosphorus. Tougher crops.
Fit within the programme
Vigor™ is the PGPR layer of the programme. 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.
Composition & material characteristics
Biological components
Bacillus subtilis (root colonisation), Pseudomonas fluorescens (phosphate solubilisation & biocontrol), Bacillus megaterium (phosphate solubilisation), 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).
Product role
Vigor™ is the PGPR layer of the programme. 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.
Research & field performance
Field research & results
- Across 180+ trial sites: solubilises bound soil phosphorus, cutting applied P by up to 25% at equal yield.
- +12% root biomass and more uniform, vigorous establishment.
- +8.1% average yield (higher on low-P, low-input, or stressed soils), with better stand and faster recovery under drought and salinity.
Crop applications
Crop-specific selection
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.
Application context
At sowing: seed treatment 4–6 g/kg, in-furrow liquid 1–3 L/ha, or granule blended with starter fertiliser. For all eight legumes; co-applies with Nodu™ (nitrogen) and Orvan™ (coupling).
Choose the product and application programme to suit the crop, growing conditions and the label that applies in your market.
