“…Synthetic biostimulants (growth regulators, inorganic salts, phenolic compounds) and natural biostimulants (plant, bacterial and algal extracts) are also increasingly often used in agricultural practice (Tambascio et al 2014). Algal extracts have complex composition and deliver various benefits, including greater yields (Wierzbowska et al 2015) and higher resistance to abi-otic and biotic stress (Kosanić et al 2015;Esserti et al 2017). Commercial extracts of Ascophyllum nodosum (Bio-Algeen S-90), Fucus spp., Laminaria spp., Sargassum spp.…”

The aim of this study was to evaluate the influence of cultivar and biostimulants on the health status of potato tubers after harvest and after 5 months of storage. The fungal pathogens isolated from potato tuber were cultured on PDA. The biostimulants limited the symptoms of dry rot in cv. Satina after harvest, in stored cv. Irga (Bio-Algeen S-90) and cv. Blaue St. Galler (Kelpak SL). The symptoms of common scab were reduced in stored potatoes cv. Satina in the Asahi SL treatment and the symptoms of late blight in stored potatoes cv. Satina in the Kelpak SL and Trifender WP treatment and in cv. Valfi in the Bio-Algeen S-90 and Kelpak SL treatment. Asahi SL and Kelpak SL decreased the severity of black scurf in stored potatoes cv. Irga. Biostimulants decreased the occurrence frequency of the causative agents of dry rot and black scurf after harvest. Total chlorogenic acid, which is predominant in potato tubers, was present in higher concentrations in the skin than in the flesh. Potato tubers had the highest content of 5-caffeoylquinic acid, followed by neochlorogenic acid (3-caffeoylquinic acid) and cryptochlorogenic acid (4-caffeoylquinic acid). Higher concentrations of chlorogenic acid were found in potato cultivars with blue-purple-and red-colored flesh than in those with yellow-and cream-colored flesh, and in response to the application of the Asahi SL biostimulant and Trifender WP.

Extracts from the brown seaweeds Cystoseira myriophylloides, Laminaria digitata and Fucus spiralis were evaluated as plant defence inducers against the wild fire disease of Nicotiana benthamiana. Seeds’ imbibition in aqueous seaweed extracts (SE) results in plants with reduced disease severity. In addition, bacterial populations were significantly reduced in these plants when compared to those germinated in sterile distilled water. They primed N. benthamiana for H2O2 accumulation and for enhanced activity of several antioxidant enzymes including catalase, ascorbate peroxidase, guaiacol peroxidase and polyphenol oxidase. These results revealed that soaking of seeds in SE before sowing allows N. benthamiana to reduce pathogen attack and can be easily applied in practice.

“…Another extract from the brown alga Lessonia trabeculata displayed a protective effect against B. cinerea on tomato leaves [11]. Moreover, in horticultural plants algal and cyanobacterial extracts were capable of increasing the transcription and the activity of defense-related enzymes involved in the control of fungal pathogens [9,15,16,17].…”

Different Antifungal Activity of Anabaena sp., Ecklonia sp., and Jania sp. against Botrytis cinerea

et al. 2019

Water extracts and polysaccharides from Anabaena sp., Ecklonia sp., and Jania sp. were tested for their activity against the fungal plant pathogen Botrytis cinerea. Water extracts at 2.5, 5.0, and 10.0 mg/mL inhibited B. cinerea growth in vitro. Antifungal activity of polysaccharides obtained by N-cetylpyridinium bromide precipitation in water extracts was evaluated in vitro and in vitro at 0.5, 2.0, and 3.5 mg/mL. These concentrations were tested against fungal colony growth, spore germination, colony forming units (CFUs), CFU growth, and on strawberry fruits against B. cinerea infection with pre- and post-harvest application. In in vitro experiments, polysaccharides from Anabaena sp. and from Ecklonia sp. inhibited B. cinerea colony growth, CFUs, and CFU growth, while those extracted from Jania sp. reduced only the pathogen spore germination. In in vitro experiments, all concentrations of polysaccharides from Anabaena sp., Ecklonia sp., and Jania sp. reduced both the strawberry fruits infected area and the pathogen sporulation in the pre-harvest treatment, suggesting that they might be good candidates as preventive products in crop protection.
