OPTISIL, r., (Si – 16.5%, Fe – 2.0%)

A silicon shield for your crops

In the face of climatic instability and high infection pressure, farmers need a tool that acts not just as a plant vitamin, but as a protective barrier. OPTISIL, produced by the Polish brand «Інтермаг», is a specialized mineral fertilizer where the leading role is played by active silicon combined with sulfur and iron.

What sets OPTISIL apart?

The main advantage of this product is the strengthening of cell walls. The silicon in the formula, applied foliarly, effectively "cements" the leaf epidermis, making it mechanically more resistant to pathogen penetration. Unlike standard micronutrient fertilizers focused solely on metabolic processes, OPTISIL physically alters the plant's structure.

• Stress Management: Enhances resistance to drought, temperature fluctuations, and lodging in cereals by thickening the stem.
• Synergistic Composition: The combination of sulfur (16.5%) and iron (2.0%) optimizes photosynthesis, which is critical for rapeseed and soybean during periods of rapid growth.
• Economic Efficiency: Application on vegetables and fruit crops reduces losses from fungal diseases, significantly lowering fungicide costs.

Who is this product best for?

OPTISIL is the ideal choice for farms using intensive technologies where yield preservation is as important as biomass accumulation. For cereal producers, it is an effective anti-lodging tool; for vegetable growers, it provides better post-harvest storage quality. The product is highly effective as a foliar spray and is compatible with most pesticides, allowing for easy integration into standard tank mixes without additional application costs.

Note: Silicon-based fertilizers require strict adherence to application rates and high-quality spraying; apply on actively growing plants for maximum nutrient absorption.
