Eco Shield is an Ortho silicic acid, the plant-available form of silicon-based bio stimulant with a micronutrient package that strengthens plant cell walls, improves nutrient uptake, and enhances your crop’s natural resistance to pests, stress, and disease—season after season.

Stronger plants start from within.

Reinforces Cell Walls

Builds a thicker mineral barrier inside the plant, increasing resilience to pests and pathogens.

Improves Nutrient Efficiency

Enhances uptake and internal mobility of key minerals for stronger, more vigorous growth.

Increases Stress Tolerance

Helps plants better withstand abiotic stress like drought, heat, and salinity—minimizing yield loss.

Intra Eco Shield is a plant-strengthening biostimulant that delivers the best results with consistent weekly application. As new leaves develop, they incorporate Eco Shield into their outer cell walls, gradually creating a full-plant barrier against both biotic and abiotic stress—including drought, heat, and salinity. This improved structural defense enhances water
regulation and promotes a more balanced nutrient uptake, such as optimizing the plant’s potassium-to-calcium (K:Ca) ratio. With regular use, growers have seen up to a 6% increase in production.


Eco Shield is a foliar-applied biostimulant that uses bioavailable silicon to strengthen cell walls, improve mineral uptake, and enhance natural plant defenses. Ideal for fruiting crops, ornamentals, and high-value greenhouse production, it helps reduce disease pressure, boost crop quality, and protect against environmental stress—without disrupting your existing spray program.

Frequently Asked Questions

Can Intra Eco Shield be combined with Intra Hydro pure?

Yes, with an irrigation system we always recommend to use Intra Hydro-pure. With a clean system, the nutrients combined with Intra Eco Shield are distributed equally to all plants. In a dirty system there is a change of nutrient deposition and pH fluctuations.
