Mode of Action

• Pseudomonas Fluorescens utilizes seed and root exudates to multiply in the rhizopshere of the soils.
• It also produces sideerophore which chelate with iron in the soil, and make it difficult for the pathogens to proliferate.
• It secretes several plant growth substances, and these gibberellins and compounds contribute to vigorous and inhibit the growth of disease causing pathogens.
• It induce systemic resistance in host plant and also produce secondary metabolite (2,4 – DAPG) 2, 4 – diacetyl phloroglucinol which is responsible for antiphyto pathogenic and bio control properties.
