Abstract

Fusarium oxysporum is one of the most destructive pathogens with wide distribution and devastating effects on vegetables. An alternative to mitigate the damage caused by F. oxysporum is the use of biostimulants, since they promote a defense response in stressful situations. The objective of this work was to evaluate the biostimulant potential of hydroalcoholic extracts of Sargassum spp. (SAR) to increase tolerance to infection by F. oxysporum in tomato seedlings. In total, 17 extracts were evaluated, which were applied in a foliar way to the seedlings at 7, 12, 22, 33 and 43 dat (days after transplantation). The induction of tolerance of the SAR extracts was evaluated in terms of incidence and severity of the disease and agronomic variables. The E12 extract showed better disease control with 17% less severity of symptoms with respect to the infected control.
