AB In the current context, characterized by the increasing global population and climate change, the priority of ensuring productivity and quality in agricultural crops has been widely recognized internationally, particularly through Sustainable Development Goal (SDG) 2 of the 2030 Agenda. However, it is crucial to address this challenge responsibly and sustainably, as emphasized by SDG 12, especially regarding the substitution of conventional phytosanitary products. This Doctoral Thesis focuses on the application of natural extracts for the control of phytopathogens, both in the pre-harvest and post-harvest phases. The emphasis is on the extraction and physicochemical characterization of a variety of extracts, including plants such as Limonium binervosum, Hibiscus syriacus, Punica granatum var. nana, Quercus suber, Sambucus nigra, Quercus ilex subsp. ballota, Tamarix gallica, Taxus baccata, Ginkgo biloba, Euphorbia serrata, Uncaria tomentosa, Armeria maritima, Silene uniflora, Helichrysum stoechas, residues like Allium sativum peels, fungi such as Ganoderma lucidum, secondary metabolites from Streptomyces spp., and purified natural products like methylxanthines. The efficacy of these extracts was assessed against pathogens affecting woody, extensive (cereals), and horticultural crops, as well as post-harvest pathogens, through in vitro, in vivo, and ex-situ trials. The results obtained reveal that the efficacy of these extracts is comparable or even superior to conventional phytosanitary products such as strobilurins or phosphonates. This approach not only proves promising in terms of pest control but also underscores the feasibility of adopting more sustainable and environmentally friendly agricultural practices, aligning with the principles outlined in the 2030 Agenda.
