Facilitates assimilation of nutrients
 Enhances stress resistance
 Increases activity in the rhizosphere 
♦ Stimulates photosynthesis 


HaifaStim™ Vital is a natural extract of micronized soft processed brown seaweed, enriched with polyphenols. It demonstrates a physio-nutritional action, guaranteed by the high content of biochemically active components: betaines, amino acids, cytokinin, mannitol, alginic acid, sugars and proteins.
HaifaStim™ Vital stimulates the plant’s physiological mechanisms and induces production of secondary metabolites under abiotic stresses, thus increasing yield and improving yield quality.
HaifaStim™ Vital is fully soluble in water and ideal for application by foliar sprays and Nutrigation™.
HaifaStim™ Vital is suitable for use in Organic Farming in accordance with Regulations (UE) No 2018/848 and 2021/1165
Control ECOCERT SA F - 32600

For best results, apply small portions of HaifaStim™ Vital throughout the growing season.
Under normal conditions, HaifaStim ™ Vital is recommended in high productivity systems to boost lateral development of shoots and roots, promote flower differentiation & development & enhance fruit development & coloring.
Under stress conditions, HaifaStim™ Vital alleviates plant stress, contributing to the energy balance, stimulating the plant physiology, producing natural precursors of phytohormones related to anti-stress activity & improving water retention in plant cells.
Compatibility: HaifaStim™ Vital can be mixed with most common plant protection products and water-soluble fertilizers. It is recommended to carry out a small-scale test before preparing a tank mix.
