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.
Competes with pathogens for iron through the production of siderophores (iron-chelating compounds), limiting pathogen growth.
Produces phytohormones (mainly auxins such as IAA), promotingroot 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.
Crops: Cereals, row crops and veggies
Main Crops: Potato, Soybean, Corn
Advantages

Azospirillum inoculant for stronger roots and plant growth
Rizospirillum ST is a high-performance biological inoculant developed by Rizobacter, based on selected strains of Azospirillum brasilense, one of the most widely recognized plant growth-promoting rhizobacteria (PGPR) in modern agriculture.
Applied directly to the seed, Rizospirillum ST colonizes the root surface and surrounding rhizosphere from the earliest stages of germination, establishing a beneficial association with the developing plant. This interaction promotes vigorous root growth, improves nutrient acquisition, and enhances the crop’s ability to access water and soil resources throughout the growing season.
In cereal crops such as corn, wheat, sorghum, rice, and other grasses, Rizospirillum ST stimulates plant vigor through a combination of biological nitrogen fixation and natural phytohormone production. It is also an excellent tool for co-inoculation in soybeans and other legumes, where it works synergistically with Bradyrhizobium species to maximize root development, nodulation efficiency, and yield potential.
By strengthening the root system and improving nutrient-use efficiency, Rizospirillum ST helps crops perform more consistently under both favorable and stressful environmental conditions.
Mode of action
Root growth stimulation: Produces phytohormones such as auxin, cytokinin, and gibberellin, promoting root development, branching, and overall root surface area.
Biological nitrogen fixation: Contributes atmospheric nitrogen to the rhizosphere, improving nitrogen availability for plant uptake.
Enhanced nutrient uptake: Improves the efficiency of nutrient acquisition and utilization, particularly during early crop development.
Improved seedling vigor: Promotes faster germination, uniform emergence, and stronger early growth.
Stress tolerance: Enhances plant resilience to drought, salinity, and osmotic stress conditions.
Rhizosphere enhancement: Improves root-microbe interactions and, in legumes, can stimulate nodulation and increase the efficiency of biological nitrogen fixation when co-inoculated with rhizobia.
Crops: Cereals, row crops and veggies
Main Crops: Corn, Soybean, Tomato
Advantages
Promotes root development and plant growth.
Supports biological nitrogen fixation
Improves nutrient and water uptake efficiency.
Enhances nodulation in legume crops
Contributes to stronger crop performance and higher yield potential

Foliar Azospirillum for better roots, nutrition and biomass
Rizospirillum Foliar leverages the proven benefits of Azospirillum argentinense Az39 to promote root growth, improves nutrient and water uptake, and supports biological nitrogen fixation. It helps growers build stronger, more resilient crops while maximizing productivity across a broad range of agricultural systems
Mode of action
Azospirillum argentinense works systematically and promotes plant growth through multiple mechanisms:
Biological Nitrogen Fixation (BNF): Converts atmospheric nitrogen (N₂) into ammonium,making it available to the plant.
Phytohormone Production: Synthesizes plant hormones like auxins (e.g., IAA),gibberellins, and cytokinins, which enhance root development and plant vigor.
Improved Nutrient Uptake: Enhances uptake of N, P, K, and other micronutrients by improving root architecture.
Siderophore Production: Helps solubilize and uptake iron.
