Symbiotics Biologicals

Bacillus Subtilis Plant Growth Promoters Features:

• Biological fungicide & plant growth-promoting bacteria (PGPR).

• Produces antibiotic compounds & lipopeptides (iturin, surfactin, fengycin) that inhibit pathogens.

• Forms a protective biofilm around roots, preventing colonization by harmful microbes.

• Stimulates plant growth by producing phytohormones (IAA, gibberellins) and enzymes.

• Enhances nutrient uptake (especially nitrogen & phosphorus).

• Improves stress tolerance in crops (heat, drought, salinity).

• Eco-friendly, non-toxic, and safe for humans, animals, and beneficial organisms.

• Reduces dependence on chemical fungicides and fertilizers, supporting organic farming.

• Effective on a wide range of crops: vegetables, fruits, cereals, pulses, oilseeds, plantation crops, and ornamentals.

• Available in talc-based / wettable powder formulation for easy handling.

•  

Key Characteristics

• Gram-positive: It has a thick peptidoglycan cell wall that retains the crystal violet stain in the Gram-stain procedure.

• Rod-shaped: The name "bacillus" means a rod-like shape.

• Aerobic: It requires oxygen for growth.

• Endospore-forming: This is its most defining and important feature.

• B. subtilis is renowned for its ability to form endospores. When faced with environmental stress like nutrient starvation, desiccation, or high temperatures, the bacterium can enter a complex sporulation process.

Bacillus Amylliquefaciens Plant Growth Promoters Features:

• Beneficial rhizobacteria widely used as a bio-fungicide and plant growth promoter.

• Effective against a broad range of soil-borne and foliar pathogens like Fusarium, Rhizoctonia, Pythium, Alternaria, Sclerotium, and Phytophthora.

• Produces antimicrobial metabolites (iturin, surfactin, fengycin, bacillomycin) that inhibit pathogenic fungi and bacteria.

• Improves nutrient uptake by solubilizing phosphorus, potassium, and micronutrients.

• Stimulates plant growth by secreting phytohormones (IAA, gibberellins) and enzymes.

• Enhances root development and plant vigor.

• Increases crop tolerance to abiotic stresses like drought, salinity, and temperature extremes.

• Eco-friendly, safe, and biodegradable, suitable for organic farming.

• Compatible with Integrated Pest Management (IPM) systems.

• Suitable for a wide variety of crops: cereals, pulses, vegetables, fruits, oilseeds, ornamentals, and plantation crops.

• Available in talc-based / wettable powder formulation for easy handling.

QuickBor (Boron ethenolamine 10% )  is a premium plant nutrient enriched with Boron that supports healthy growth, flowering, and fruit setting. It prevents boron deficiency, enhances nutrient transport, and improves overall crop yield while ensuring strong plant development.

Bacillus subtilis and Bacillus pumilus are two species of beneficial bacteria widely used in agriculture as biopesticides and biofertilizers. They are often found together in commercial microbial consortia products.
Combined Uses and Benefits in Agriculture

When used together, these two bacteria create a powerful synergistic effect for plant health and protection.

1. Disease Control (Their Primary Strength)

They act through multiple modes of action to suppress a wide range of fungal and bacterial pathogens:

• How they work:

  • Direct Antagonism: They produce a cocktail of natural antibiotic compounds that inhibit or kill pathogenic fungi and bacteria.

  • Competition: They rapidly colonize the rhizosphere (root zone) and phyllosphere (leaf surface), consuming all the available food and space, leaving nothing for pathogens.

  • Induced Systemic Resistance (ISR): They "warn" the plant of potential pathogen attacks, triggering the plant's natural defense systems (like producing defensive enzymes) before an infection takes hold.

• Diseases they help control:

  • Root Rots: Caused by Fusarium, Rhizoctonia, and Pythium.

  • Wilt Diseases: Fusarium and Verticillium wilt.

  • Foliar Diseases: Powdery mildew, Downy mildew, Early blight, Late blight, Gray mold (Botrytis), and Bacterial spot.

2. Plant Growth Promotion

They are not just protectors; they are also highly effective growth promoters.

• Phosphorus Solubilization: Both species convert locked, insoluble phosphorus in the soil into a soluble form that plants can absorb, reducing the need for phosphate fertilizers.

• Stimulating Root Development: They produce plant hormones (like auxins) that lead to larger, more robust root systems. A bigger root system means better water and nutrient uptake, leading to stronger, more resilient plants.

• Siderophore Production: They can produce siderophores, which are compounds that chelate iron, making this essential micronutrient more available to the plant.

3. Soil Health Enhancement

• As spore-forming bacteria, they are very resilient and can improve the microbial diversity of the soil.

• They contribute to the breakdown of organic matter and the cycling of nutrients.

Bacillus Licheniformis (PGPR)

• Beneficial biofertilizer & biocontrol agent containing the naturally occurring bacterium Bacillus licheniformis.

• Promotes plant growth by producing enzymes and phytohormones that stimulate root development.

• Enhances nutrient availability by solubilizing phosphorus, zinc, and other essential minerals.

• Produces antimicrobial compounds that suppress harmful soil-borne pathogens (Fusarium, Rhizoctonia, Pythium, etc.).

• Improves soil health by balancing microbial populations and increasing organic matter decomposition.

• Eco-friendly & safe for humans, animals, and beneficial organisms.

• Helps crops withstand abiotic stress (salinity, drought, heat).

• Reduces dependency on chemical fertilizers and fungicides, supporting organic farming.

• Suitable for a wide variety of crops including vegetables, cereals, pulses, fruits, oilseeds, and plantation crops.

• Available in powder (talc-based / carrier-based) formulation for easy seed treatment and soil application.
