Xurian® (500g)

Xurian^® - Rhizospheric biofertilizer for maximum nutritional and structural soil efficiency

Biofertilizer of biological origin formulated as a wettable powder (WP), based on the bacterium Pseudomonas putida strain I-4613 (1×10⁸ CFU/g), enriched with 50% maltodextrin. This exclusive strain, deposited at the Institut Pasteur, was selected for its high capacity for phosphorus solubilization and plant growth promotion, acting directly in the rhizosphere of agricultural crops.

Mode of action and physiological benefits

Application of the product activates a series of biological processes that benefit the plant from day one:

• Release of plant hormones - Indole-3-acetic acid (IAA) - regulates the development of plant organs and the coordination of growth and Gibberellic acid (GA3) - stimulates cell elongation and division, promoting vegetative growth;
• Production of enzymes and secondary metabolites - Phosphatases - solubilize immobilized phosphorus and accelerate the humification of organic matter and Other bioactive compounds - increase soil porosity and water retention;
• Effective rhizosphere colonization - Maltodextrin favours the initial assimilation and multiplication of the bacterium, ensuring rapid and controlled establishment in the root zone.

Recommended crops and application

• Target crops: Vineyard, fruit trees, commercial vegetable crops and high-yield perennial or annual crops;
• Method of application: Soil spraying or via irrigation (drip, sprinkler or flooding) at the recommended dose - 1.5 kg/ha diluted in 150 L of water, with constant agitation;
• Compatibility: Apply on soils with pH between 5 and 9. Avoid mixtures with incompatible products (e.g.: glyphosate).

Agronomic and environmental advantages

• Improvement of the soil structure in the rhizosphere zone;
• Increased nutrient availability, especially phosphorus, calcium and iron;
• Promotion of root and vegetative growth;
• Stimulation of photosynthetic activity and biomass production;
• Greater tolerance to abiotic stress (drought, salinity and temperature);
• Reduction of the need for conventional fertilization in the medium/long term;
• Authorized for Organic Farming and Integrated Production.

Dose: 1,5kg/ha (2 applications of 750g distributed throughout the cycle).
