Pseudomonas fluorescens is a plant-growth-promoting rhizobacterium (PGPR) and bio-fungicide that colonizes roots, produces antifungal metabolites, induces systemic resistance (ISR), and enhances nutrient uptake. Formulated at  2 × 10^8 cells per gram on a talc carrier, it provides chemical-free disease control and yield improvement.

Product Specifications

  • CFU: 2 × 10^8 cells/gram

  • Active Content: Live cells and secondary metabolites of Pseudomonas fluorescens 

  • Carrier: Dextrose powder (pH 6.5–7.5 for bacterial stability)

Usage Instructions

  1. Dosage: 500 g–1 kg/acre in 200 L water for soil drench/foliar spray.

  2. Timing: Apply at sowing, transplanting, or early disease signs; avoid hot/dry conditions (>35°C).

  3. Target Pathogens:

    • Fusarium oxysporum (wilt), Rhizoctonia solani (damping-off), Pythium spp. (root rot)

    • Phytophthora infestans (late blight), Magnaporthe grisea (rice blast)

  4. Method:

    • Soil: Drench root zone or mix with compost (1 kg/100 kg).

    • Seeds: Treat with 10 g/kg slurry (add 10% jaggery as adhesive).

  5. Frequency: Apply every 15 days; reapply after flooding/heavy rain.

  6. Compatibility: Avoid copper-based fungicides; compatible with Trichoderma viride and Bacillus subtilis.

  7. Activation: Maintain soil moisture >50% for 48 hours to boost colonization.

  8. Safety: Non-phytotoxic; safe for earthworms, fish, and pollinators.

Suitable Crops

  • Vegetables: Tomato (vs. Fusarium wilt), Potato (vs. Phytophthora), Onion (vs. Pythium)

  • Cereals: Rice (vs. Magnaporthe blast), Wheat (vs. Rhizoctonia), Maize

  • Legumes: Chickpea (vs. Sclerotinia), Soybean (vs. charcoal rot)

  • Fruits: Banana (vs. Panama wilt), Grapes (vs. crown gall), Citrus

  • Others: Cotton, Sugarcane, Turmeric

Storage Instructions

  • Temperature: 4–15°C (refrigeration mandatory; avoid >25°C).

  • Packaging: PP Bags

  • Shelf Life: 24 months (test viability if stored >6 months).

  • Precautions: Do not freeze; protect from UV and humidity.

Key Advantage

Metabolite-Mediated Suppression:
Produces antifungal compounds (phenazines, 2,4-DAPG, pyoluteorin) that lyse hyphae of Phytophthora infestans and Fusarium oxysporum while solubilizing iron/phosphorus for plant growth.
