Plants sprayed using seaweed extract are also characterized by a higher
resistance to pest and pathogens pressure and by a better absorption of
nutrients from the soil. Seaweed extracts contribute to recovery following
damage caused by insects and bacterial and fungal diseases.Seaweeds
based formulations are rich in phytohormones (Gibberellins,Auxines,
Cytokinins),in amino acids and in essential fatty acids that are responsible
for the growth of the plant,its development, and its resistance to pathogens.
The biostimulant activity of extracts obtained from marine seaweed is linked
to the presence of plant growth regulators, especially cytokinins mainly
responsible for delaying the aging process of the plant,inducing mytosis,
stimulating the maturation of the chloroplast, the growth of the young
shoot and lateral buds.
