Name

Ortho Silicic Acid (OSA) 2.0% WSL

• Composition: Ortho Silicic Acid (Si(OH)4) – minimum 2.0% w/w
• Plant Available Silicon (Si) equivalent: minimum 0.6% w/w
• Formulation: Liquid concentrate
• pH (1% solution in distilled water @ 20°C): Typically ranges from 1.7 to 2.2 (acidic)
• Solubility in Water: Fully soluble
• Mode of Entry: Systemic
• Mode of Action: Strengthens plant cell walls, improves stress resistance, enhances nutrient absorption.
• Color: Clear transparent free-flowing liquid (can vary slightly by manufacturer)
• Purity: Often stated around 99% for the active ingredient.
• Specific Gravity: Typically between 1.07 – 1.15 g/cm³.

• Enhanced Plant Strength & Rigidity: Strengthens cell walls, leading to tougher leaves and stems, reducing lodging (stem breakage) and improving plant architecture.
• Increased Pest & Disease Resistance: Creates a physical barrier and activates plant defense mechanisms against various pests (e.g., sucking insects) and fungal diseases (e.g., powdery mildew, blast).
• Improved Abiotic Stress Tolerance: Helps plants withstand environmental stresses such as drought, salinity, heat, and cold by regulating water uptake and reducing transpiration.
• Optimized Nutrient Uptake: Enhances the uptake and utilization of other essential nutrients, particularly phosphorus and nitrogen, improving nutrient use efficiency.
• Reduced Heavy Metal Toxicity: Binds to and detoxifies heavy metals in the soil, preventing their uptake by plants.
• Improved Photosynthesis: Contributes to more erect leaves, allowing for better light interception and increased photosynthetic activity.
• Higher Yield & Quality: Leads to healthier plants, resulting in improved fruit set, better quality produce, and ultimately higher yields. The consistent application of Ortho Silicic Acid promotes robust growth.

• Foliar Spray: Dilute the recommended amount in water and spray evenly over plant foliage.
• Drip Irrigation/Fertigation: Mix with irrigation water for direct application to the root zone.
• Soil Drench: Apply directly to the soil around the base of the plant.

• Vegetative Stage: Apply during early vegetative growth to build strong foundational structures.
• Flowering & Fruiting Stages: Continue application to support reproductive growth, fruit development, and enhance resistance during critical phases.
• Stress Conditions: Apply before or during anticipated stress periods (e.g., heatwaves, drought, pest outbreaks) to bolster plant resilience.
• Frequency: Typically recommended every 10-15 days, or as per specific crop requirements and observed conditions. Consult agricultural experts for precise timing.

• Always wear appropriate personal protective equipment (PPE) such as gloves, eye protection, and protective clothing during handling and application.
• Avoid direct contact with skin and eyes. In case of contact, rinse immediately with plenty of water.
• Do not ingest. Keep out of reach of children and pets.
• Store in a cool, dry place away from direct sunlight and extreme temperatures.
• Do not mix Ortho Silicic Acid with highly acidic or alkaline materials unless compatibility is confirmed through a jar test.

• 200 Liters / 200 Kg HDPE Drum
• Customizable as per client/manufacturer/trader requirement (e.g., 5L, 20L, 50L containers).
