OPTISIL, r., (SiO2– 16,5%, Fe – 2,0%)

A Silicon Shield for Your Crops

In the current era of climate instability and high pathogen pressure, crops need more than just standard NPK fertilizers. ОПТИСИЛ, р., (SiO2- 16,5%, Fe - 2,0%), produced by the Polish company Інтермаг, is a specialized silicon-iron complex designed to reinforce the physical structure of plants.

Unlike traditional biostimulants that operate at a biochemical level, OPTISIL acts as a structural “armor.” Soluble silicon (SiO2) is deposited into the cell walls of the epidermis, making them denser and more rigid. This is a crucial adaptation for crops prone to lodging (like cereals) or those susceptible to damage from pests with chewing mouthparts.

Key Advantages of Using OPTISIL

• Enhanced Resistance: A thickened leaf cuticle makes it physically difficult for fungal spores to penetrate, significantly reducing the risk of powdery mildew and other foliar diseases.
• Stress Protection: Silicon helps the plant manage moisture more efficiently. During periods of drought or intense heat, this fertilizer minimizes transpiration, allowing the crop to maintain turgor pressure.
• Iron Synergy: The inclusion of 2% readily available iron (Fe) prevents chlorosis and supports photosynthetic activity, which has a direct impact on crop quality and final yield metrics.

This product is an optimal choice for agronomists practicing intensive farming who aim to reduce reliance on heavy pesticide usage. Foliar application of OPTISIL has shown high efficacy in rapeseed, soybeans, and vegetable crops, especially during pre-flowering and fruit filling stages. OPTISIL is not a replacement for basal fertilizers, but rather an essential “insurance” tool for safeguarding the future harvest against environmental and physical stressors.
