Pseudomonas Fluorescens Bactericide

Pseudomonas fluorescens Bactericide is a biological plant protection formulation engineered for commercial soil-borne bacterial pathogen control, root system colonization, and plant systemic defense induction. Containing high-potency, viable strains of Pseudomonas fluorescens, this microbial bactericide suppresses root-rot and vascular pathogens through metabolite secretion, iron chelation, and competitive exclusion while concurrently mitigating root damage caused by parasitic nematodes. Supplied in wettable powder and liquid concentration formats, it is formulated for seamless integration into commercial drip irrigation, soil drenching, and seed treatment workflows without clogging application equipment.

Active Organism: Pseudomonas fluorescens

Biological Nature: Gram-negative, rod-shaped beneficial rhizobacterium

Standard Potency: 2 Billion CFU/g (Wettable Powder) | 1 Billion CFU/mL (Liquid Concentrate)

Purity Standard: Zero synthetic pesticide residues; bacterial purity at or above 99.5 percent with no pathogenic contaminants such as Salmonella or Escherichia coli

Production Method: Submerged liquid fermentation under strict sterile controls, optimized for secondary metabolite yield and cell stability

Secondary Metabolite Antibiosis: Produces bioactive compounds including 2,4-diacetylphloroglucinol, phenazine derivatives, and pyrrolnitrin that disrupt pathogenic bacterial cell walls and inhibit fungal spore germination.

Siderophore-Mediated Iron Chelation: Secretes high-affinity iron-binding siderophores named pyoverdine that sequester ferric iron in the rhizosphere, depriving soil-borne plant pathogens of essential micronutrients.

Induced Systemic Resistance: Triggers host plant endogenous defense pathways, prompting the accumulation of phytoalexins and defense-related proteins to build systemic defense against vascular wilt and soft rot.

Rhizosphere Competitive Exclusion: Rapidly colonizes the root zone, forming a biological barrier that blocks pathogenic entry points and outcompetes opportunists for root exudates and physical space.

Solanaceous Crops (Tomatoes, Peppers, Eggplants): Applied via drip irrigation at seedling transplanting to prevent bacterial wilt and suppress root-knot nematodes during early vegetative stages.

Cucurbits (Cucumbers, Melons, Squash): Administered through soil drenching to control root-rot complexes and enhance root biomass development under high moisture conditions.

Leafy Vegetables and Brassicas (Lettuce, Cabbage): Used in field fertigation to limit bacterial soft rot expansion ahead of canopy closure.

Tuber and Bulb Crops (Potatoes, Onions, Garlic): Integrated into seed piece treatments or in-furrow sprays at planting to suppress soil-borne skin defects and soft rot vectors.

Fruit Trees and Vineyards: Applied around the dripline in spring to establish protective root zones against bacterial gall disease and lesion nematode populations.

Greenhouse and Hydroponic Systems: Recirculated at low dosages to maintain biological control in closed substrate systems without altering electrical conductivity or pH balance.

Wettable Powder: Fine dry powder featuring immediate wetting and long suspension stability; designed for bulk tank mixing and drip systems.

Suspension Concentrate / Liquid: Aqueous formulation optimized for automated dosing, seed coating machinery, and hydroponic injectors.

Commercial Bulk Packaging: 1 kg aluminum foil bags (20 bags per carton), 5 kg re-sealable pouches, or 25 kg fiber drums with inner polyethylene liners.

Liquid Packaging Options: 1 L fluorinated high-density polyethylene bottles, 10 L jerrycans, or 1000 L intermediate bulk containers.

Custom Packaging Services: Custom concentration adjustments, specialized unit packaging sizes, and private labeling available for global commercial partners.

Certificate of Analysis: Provided for every production batch detailing verified CFU counts, physical property tests, and contaminant screening.

Material Safety Data Sheet: Fully compliant with global chemical safety standards and occupational requirements.

Compatibility Guide: Tank-mix matrix data detailing safe combination parameters with fertilizing salts, organic additives, and selective crop inputs.

Batch Traceability Report: Fermentation logs, quality testing records, and sample retention tracking indexed per lot number.
