摘要：The study was carried out to evaluate the effect of brown alga crude extracts of Cystoseiratamariscifolia and Bifurcaria bifurcata against the mycelium (growth of) Botrytis cinereainducing grey mold during tomato postharvest. The results showed that the hexanicextract (91,000ppm) and the aqueous one (49,600ppm) have a very important inhibitorypotency against the tested fungi with a very small amount of 100 µL. The importantactivity was obtained with the hexanic extract of C. tamariscifolia against B. cinerea withan inhibition zone up to 2 ± 0.18cm. The treatment of tomato fruits inoculated with thefungal species, with the aqueous extract of the brown algae ensures their protectionagainst the phytopathogenicity of the fungus. An important protection was obtained alsowith the aqueous extract of B. bifurcata. Metal contents analysis show that these twoseaweeds are not harmful.The practical use of seaweeds during postharvest opens a new way in the biologicalcontrol. Their extracts could be an ecofriendly alternative for the protection of cropsagainst pathogens.
