Symbiotics Biologicals

• Biological fungicide & bio-control agent prepared from the beneficial fungus Trichoderma viride.

• Effective against a wide range of soil-borne fungal pathogens such as Fusarium, Rhizoctonia solani, Pythium, Sclerotium, and Phytophthora.

• Works through mycoparasitism, antibiosis, and competition, suppressing harmful fungi in the rhizosphere.

• Stimulates plant growth by inducing systemic resistance and producing growth-promoting substances.

• Improves germination, root growth, and overall plant vigor.

• Enhances soil fertility and microbial balance.

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

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

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

• Suitable for vegetables, fruits, cereals, pulses, plantation crops, ornamentals, and oilseeds.

Pseudomonas fluorescens is a common, Gram-negative, rod-shaped bacterium. It is known for several key characteristics:

• Fluorescence: As the name suggests, it produces a soluble, yellow-green pigment called pyoverdine that fluoresces under ultraviolet light. This is its most recognizable trait.

• Metabolic Versatility: It can metabolize a wide range of organic compounds, allowing it to survive in diverse environments.

• Motility: It moves using one or more polar flagella.

• Oxygen Requirement: It is a strict aerobe (requires oxygen to grow).

• Habitat: It is found ubiquitously in soil, water, and on plant surfaces. It prefers moist environments.

• Key Characteristics and Importance1. Beneficial Role in Agriculture & Biocontrol

  This is the most significant positive aspect of P. fluorescens. It is a prominent PGPR (Plant Growth-Promoting Rhizobacterium).

  • Biocontrol Agent: It protects plants from pathogenic fungi and bacteria through several mechanisms:

    • Antibiotic Production: It produces a variety of potent antibiotics, including 2,4-diacetylphloroglucinol (DAPG), pyoluteorin, and pyrrolnitrin.

    • Siderophores: It produces pyoverdine, which is a siderophore—an iron-chelating molecule. By sequestering all available iron in the rhizosphere, it "starves" pathogenic microbes of this essential nutrient.

    • Induced Systemic Resistance (ISR): It can "prime" the plant's immune system, making it more resistant to future pathogen attacks.

    • Competition: It aggressively competes for space and nutrients on the plant root surface.

  • Plant Growth Promotion:

    • Phytohormone Production: Some strains produce hormones like auxins that stimulate root growth.

    • Nutrient Solubilization: It can make nutrients like phosphorus more available to the plant.
