 Enhances the plant’s mechanical strength 
 Improves water use efficiency
 Increases productivity and improves yield


HaifaStim™ Wall-Up S is the most concentrated and efficient source of silicon for plants, based on innovative ortho-silicic acid technology. It also serves as a source of iron (Fe), which is provided as fully water-soluble EDTA chelate – for maximum stability and efficiency.  
HaifaStim™ Wall-Up S helps build plant’s cell walls, thus enhancing mechanical strength, increasing tolerance to abiotic stresses and improving yield quality and extending post-harvest life.
HaifaStim™ Wall-Up S is ideal for foliar application and suitable for Nutrigation™.
HaifaStim™ Wall-Up S is approved in Organic Farming in accordance with Regulations EU 2018/848 and 2021/116
