Dextrose Based Bacillus Subtilis Powder Formulation (Water Soluble)

Bacillus subtilis is a gram-positive, rod-shaped bacterium used as a broad-spectrum bio-fungicide and plant growth promoter. It colonizes roots, produces antifungal metabolites, induces systemic resistance (ISR), and enhances nutrient availability. Formulated at 2 × 10⁹ CFU/g on a talc carrier, it offers chemical-free disease control and yield enhancement.

Product Specifications

• CFU: 2 × 10⁹ per gram (2 billion viable spores/g)

• Active Content: Endospores and vegetative cells of Bacillus subtilis

• Carrier: Dextrose powder (ensures stability and adhesion)

Usage Instructions

1. Dosage: 500 g–1 kg per acre, mixed in 200 L water for soil/foliar application.

2. Timing: Apply at sowing, transplanting, or early disease symptoms; avoid extreme heat (>35°C).

3. Target Pathogens:

   • Fungal: Fusarium oxysporum (wilt), Rhizoctonia solani (root rot), Sclerotium rolfsii (stem rot)

   • Bacterial: Ralstonia solanacearum (bacterial wilt), Xanthomonas campestris (black rot)

4. Method:

   • Soil Drench: Apply to root zone.

   • Seed Treatment: 10 g/kg seeds (slurry method).

   • Foliar Spray: Cover both leaf surfaces.

5. Frequency: Apply every 15–20 days; repeat after irrigation/rain.

6. Compatibility: Do not mix with copper-based fungicides; compatible with Trichoderma spp.

7. Activation: Maintain soil pH 6–7.5 and moisture for optimal colonization.

8. Safety: Non-toxic to plants, bees (Apis mellifera), and fish.

Suitable Crops

• Vegetables: Tomato, potato, chilli, onion, cucurbits

• Fruits: Banana, grapes, citrus, pomegranate, strawberries

• Cereals: Rice, wheat, maize

• Legumes: Soybean, chickpea, groundnut

• Others: Cotton, sugarcane, turmeric, flowers

Storage Instructions

• Temperature: 4–25°C (refrigeration extends viability).

• Packaging: Airtight, opaque containers; protect from UV/humidity.

• Shelf Life: 24 months from manufacture.

• Precautions: Avoid contamination; reseal tightly after use.

Key Advantages

Systemic Disease Resistance:
Suppresses resistant strains of Colletotrichum gloeosporioides (anthracnose) and Phytophthora capsici (blight) while solubilizing phosphorus, fixing nitrogen, and producing growth-promoting enzymes (e.g., ACC deaminase).
