Microbial Strains and Bio-Fertilizer Portfolio
Bio-fertilizers supply living microorganisms that colonize the rhizosphere and facilitate nutrient availability in agricultural soils.
Formulated under strict Fertilizer Control Order (FCO) biological standards, these microbial inoculants boost nutrient use efficiency.
- Rhizobium: Symbiotic nitrogen-fixing bacteria tailored for pulse and legume seed treatment
- Azotobacter & Azospirillum: Free-living and associative nitrogen fixers for cereals, sugarcane, and vegetables
- Phosphate Solubilizing Bacteria (PSB): Secretes organic acids that dissolve locked insoluble soil phosphates
- Potash & Zinc Solubilizing Bacteria (KSB/ZSB): Mobilizes mineral potassium and zinc into plant-available ionic forms
Bio-Pesticides and Biological Disease Suppression
Biological crop protection utilizes beneficial entomopathogenic fungi and antagonistic microorganisms to manage pests and diseases.
These bio-agents establish living colonies that parasitize target pests without leaving toxic chemical residues on produce.
- Trichoderma viride & T. harzianum: Antagonistic bio-fungicides controlling Fusarium wilt, root rot, and damping-off
- Pseudomonas fluorescens: Bacterial bio-agent producing systemic resistance and controlling bacterial blights
- Beauveria bassiana & Metarhizium anisopliae: Entomopathogenic fungi managing white grubs, caterpillars, and borers
Application Practices, Seed Inoculation, and Storage
Bio-fertilizers and bio-pesticides are applied as seed treatments, seedling root dips, or compost enrichments.
Because they contain living microorganisms, protect products from direct sunlight, chemical fungicides, and excessive storage heat.
- Seed treatment: Coat seeds with microbial slurry using jaggery solution as an adhesive and shade-dry before sowing
- Chemical separation: Maintain a gap of at least five to seven days between bio-agent application and chemical fungicide sprays
- Storage conditions: Store in cool, shaded rooms at temperatures below thirty degrees Celsius

Common questions
What is the primary function of Phosphate Solubilizing Bacteria (PSB)?
PSB secretes organic acids that solubilize fixed, insoluble soil phosphates into plant-available orthophosphate ions.
Can bio-fertilizers like Trichoderma be mixed with chemical fungicides?
No, chemical fungicides will kill living beneficial Trichoderma spores; maintain at least a 5 to 7 day interval between applications.
How does Rhizobium bio-fertilizer benefit pulse crops?
Rhizobium forms root nodules on pulse roots that fix atmospheric nitrogen, providing natural nitrogen nutrition and enriching soil.
