By the definition for the biostimulator, Reglalg contains substances extracted from algae that stimulate the natural plant processes that improve their tolerance to environmental abiotic stress, nutrient-use efficiency, quantity, and quality of the crop. During several years of testing, it has been demonstrated that due to the beneficial influence of Reglalg on the vigor and viability of different plant species, the plants are also less affected by biotic stress factors. Due to these properties, the biostimulator Reglalg is a highly effective preparation for use in organic agriculture.
