Asweed is a special bioactivator based on natural organic extracts derived from the brown seaweed Ascophyllum nodosum, formulated to synergistically and naturally stimulate plant growth and development processes. The formulation contains over 60 organic compounds, including macro and micronutrients, natural phytohormones (auxins, gibberellins, cytokinins), vitamins, enzymes, peptides, free amino acids, phytochromatic substances, and carbohydrates. These components are rapidly and fully assimilable by plants both through foliar and root uptake. The presence of natural phytohormones gives the product strong bioactivating properties, stimulating vegetative growth, cell division, and flowering, while also enhancing stress tolerance and delaying cellular aging. Mannitol and alginates, together with betaines, play a key role in chelating and osmoregulatory activity, improving nutrient availability and increasing resistance to water and salt stress. Enriched with essential amino acids and polyphenols, Asweed promotes vegetative development, tolerance to thermal stress (both high and low temperatures), and the production of phytoalexins, thereby strengthening the plant’s resistance to abiotic stress. Thanks to its formulation, Asweed supports flowering and fruit set, enhancing both quality and yield, and contributing to more efficient resource use, resulting in cost reduction.
