Ortho Silicic Acid (OSA) 2.0% WSL

Ortho Silicic Acid is a silicon source. Ortho Silicic Acid (OSA) 2.0% WSL is an elite, water-soluble liquid silicon product that was developed and patented to give growers an available and an incredibly easy-to-use form of silicon, one of the most important nutrients for your plants. Silicon, which is found in higher abundance within soil, is often present in a form that’s not easily accessible by plants. OSA 2.0% WSL enables efficient absorption and utilization which enables plants to harness the full power of silicon at key growth stages. It acts by hardening the cell walls in plants, adding structural integrity, increasing resistance to stress and increasing overall plant vigour and productivity.

• 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.

• Improves Plant Strength & Structure: Reinforces cell walls resulting in stronger leaves and stems, helping to prevent lodging (stem breakage) and support plant architecture. 

• Enhanced Pest & Disease Resistance: Form a physical b Arrie and stimulate plant defence responses against numerous pests and fungal diseases (such as sucking insects and powdery mildew, blast). 

• Enhanced Abiotic Stress Resistance: It assists plants in resisting environmental stresses such as drought, salty, hot and cold by promoting the water retention and decreasing the transpiration. 

• Optimizes Nutrient Uptake: Maximizes the uptake and utilization of other essential nutrients, particularly phosphorus and nitrogen, increasing nutrient use efficiency. 

• Lower Heavy Metal Toxicity: Attaches and then neutralizes heavy metals in the soil, making them unavailable for plant uptake. 

• Enhanced Photosynthesis: Contributes to a more erect leaf posture for better light interception and enhanced photosynthesis. 

• Higher Yield & Quality: Aids in healthier plant, increasing fruit set, improved quality and yield, ripen fruits uniformly and improve sweetness. A consistent use of Ortho Silicic Acid promotes strong plants. 

Application of Ortho Silicic Acid (OSA) 2.0% WSL can made by any method selected from:

• Spray: Mix with water and spray evenly over plant surface, cover all parts of leaves.
• Drip Irrigation/Fertigation: Apply through the irrigation water for direct application to the rooting zone.
• Drench: Apply directly to the soil through the soil surface or use through irrigation.

• 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.
