The silicon (orthosilicic acid) developed for ArgicinPlus and Algicin can also be used on its own. It strengthens the leaf cellular walls and surface, considerably reducing the chance of fungal infections in the leaf. Si also facilitates the better distribution of Ca and Mn throughout the plant and helps reduce drought stress.

You can read all about the element Si in our more elaborate article. 

With 3% orthosilicic acid, SilicaPower has a high concentration of Si that is readily taken up by the plant. This is clearly shown in this chart. 

Plant sap measurements from three cut hydrangea cultivars show a clear increase in Si.


  • Spray 100 ml SilicaPower/100 litres water with a minimum of 500 ml/ha, or
  • Add to the A fertilizer feeder or separate fertilizer injector: 350 ml SilicaPower/ha/week.

Spraying interval

Spray once every 7 days or every 5 days a few times to reduce drought stress during dry periods.

Advantages SilicaPower

  • more intense flower colour: continues through to full bloom
  • thicker, harder leaves and better leaf arrangement
  • stronger cell walls
  • better root penetration
  • higher chlorophyll production, leading to more photosynthesis
  • plant resistance increases
  • transpiration decreases, less drought stress
  • redistribution of Ca and Mn, reducing the risk of nutrient toxicity
  • larger quantity of the CO2 fixation enzyme Rubisco
  • easy to take up form of Si:
  • SiO2 cannot be taken up by plants, however the orthosilicic acid, (H4SiO4) in SilicaPower can.
  • easy to use, via the fertilizer feeder or as a foliar spray
  • liquid, dissolves easily in the fertilizer feeder
  • less Si needed for the same results:

  • highly cost effective compared with other silicon products

  • pH neutral: no acidification required afterwards

  • 100% systemic: 
    the solution sprayed onto the leaf is distributed to the roots immediately

  • no residues, no growth inhibition, no re-entry term, no safety term

In other words: increase production and the quality of your crops.
Reap these benefits by adding the element Si , combined with the specific advantages of using SilicaPower. 


  • Use silicon to strengthen cell walls and harden the leaf surface.
    This reduces the risk of fungal and bacterial infections.
  • Our experience shows similar results with e.g. Erwinia in Phalaenopsis.
