Bacillus Subtilis Powder Formulation (Water Insoluble) Talc Based Powder 2x10^8 cells/gram

Technical Information

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.

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.

1. Frequency: Apply every 15–20 days; repeat after irrigation/rain.
2. Compatibility: Do not mix with copper-based fungicides; compatible with Trichoderma spp.
3. Activation: Maintain soil pH 6–7.5 and moisture for optimal colonization.
4. Safety: Non-toxic to plants, bees (Apis mellifera), and fish.

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).
