About Orthosil
Orthosil by Multiplex is a water-soluble Ortho Silicic Acid (OSA) 2.0% beneficial element fertilizer that supplies plant-available silicon to all crops. It helps crops handle water, temperature, and nutrient stress and supports plant strength, growth, and yield. It is applied as a foliar spray.
Orthosil Technical Content
Ortho Silicic Acid {Si(OH)₄} 2.0% w/w min (Water Soluble Liquid), with plant available silicon (Si) equivalent of 0.6% w/w min.
Mode of Action
Silicon absorbed through the leaves strengthens plant tissues and supports tolerance to water, temperature, and nutrient stress. It also helps the plant build natural defence against fungal and insect attacks.
