Rizofos Argentina

RIZOFOS is a biological inoculant and plant growth promoter developed by Rizobacter. It contains selected strains of Pseudomonas pergaminensis, a beneficial soil microorganism that enhances nutrient availability and improves the efficiency of natural soil resources.

One of the main challenges in crop nutrition is phosphorus immobilization. Although phosphorus may be present in the soil or supplied through conventional fertilizers, a significant portion becomes chemically bound to calcium, iron, or aluminum compounds, making it unavailable for plant uptake. Rizofos addresses this limitation by naturally releasing bound phosphorus and zinc into plant-available forms.

By improving nutrient accessibility in the rhizosphere, Rizofos promotes rapid crop establishment, stronger root systems, and more efficient nutrient utilization, contributing to increased productivity and sustainable agricultural performance.

Mode of action

Pseudomonas pergaminensis is a plant growth-promoting rhizobacterium (PGPR) with multiple modes of action, depending on the strain and formulation:

• Competing with pathogens for iron using siderophores (iron-chelating compounds), starving the pathogen.
• Growth Promotion
• Produces phytohormones (mainly auxins such as IAA), promoting root growth and development.
• Releases compounds such as 2,3-butanediol and acetoin, which act as biostimulants.
• Enhances nutrient uptake (especially phosphorus, zinc and micronutrients).
• Produce gabD (aminotransferase) that reduces stress.
• Activates photosystems I and II.
