Fungal diseases caused by Fusarium spp. significantly threaten food security and sustainable agriculture. One of the traditional strategies for eradicating incidents is use chemical synthetic fungicides. The excessive these products generates environmental damage has negative effects on crop yield. It puts plants in stressful conditions, kills natural soil microbiome, makes phytopathogenic fungi resistant. Finally, it also causes health problems farmers. This drives search selection alternatives, such as bio-fungicides. Among products, algae cyanobacteria are promising sources antifungal bio-compounds. These organisms can synthesize different bioactive molecules, fatty acids, phenolic some volatile organic compounds with activity, which fungal cell membrane that surrounds hyphae spores, either solubilization or making them porous disrupted. Research this area still developing, but significant progress been made identification potential controlling important pathogen. Therefore, review focuses knowledge about mechanisms action acids from macroalgae, microalgae, principal biomolecules well benefits challenges applying metabolites against to achieve

Plants have developed many defensive mechanisms to maintain their metabolism and growth under stress that, albeit inadequate with increased soil salinization rates climate change, deliberately affect plant growth, productivity, quality. As an alternative, yet effective, economical, sustainable choice of environmentally benign source, seaweeds are proving be potential replacements for conventional protectants biostimulants. Seaweed extracts from various families known exert ameliorating effect in plants affected by salt as a cumulative action sequential bio array compounds diverse categories such phytohormones (Auxin, cytokinin, Gibberilic acid), polyamines (putrescine spermidine), phenolics (Vanillic gallic protein (Taurine, phosphoserine), carbohydrates (Trehalose, sorbitol, mannitol) betaines (glycine proline beatine, glycine, aminobutyric acid). These sought promote the production accretion ameliorative osmolytes that activates MAPK pathway, triggering signal cascades activating several genes miRNAs Na+ compartmentalization, Cl− efflux, increase cytosolic Ca+, ion homeostasis, cell–organ integrity. An rate antioxidant enzymes (peroxidase, superoxide dismutase, ascorbate peroxidase) rapidly scavenging reactive oxygen species is also observed. Consequently, there chlorophyll activities promoting sugar allocation, water, resource utilization efficiencies, thereby protecting productivity eco-friendly effective manner.
