The present work focuses on the assessment of eight combinations of natural products with chitosan oligomers with fungicidal capacity that may be effective in the integrated control of powdery mildew, in compliance with Article 14 of the European Directive 2009/128/EC. Their efficacy was evaluated in field conditions against natural infections, in a plot with high disease pressure during a growing season (assaying both foliar or root application), and against overwintering inoculums (chasmothecia) through in vitro tests. In addition, their possible biostimulant capacities were evaluated based on harvest yields. Treatments based on chitosan oligomers in combination with secondary metabolites of Streptomyces spp. and chitosan oligomers combined with hydrolyzed gluten showed the best results in terms of disease control. Given the high efficacy of these formulations, comparable to that of conventional antifungals, they constitute an interesting alternative for the control of this disease whose treatment can, in some cases, represent almost half of the production costs. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.7 2022 AGRONOMY 16 / 88 = 0.182 2022 Q1 T1 PLANT SCIENCES 60 / 239 = 0.251 2022 Q2 T1 0.663 2022 Agronomy and Crop Science 2022 Q1 5.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sánchez Hernández, Eva Baquero Foz, Rubén Martín Ramos, Pablo Universidad de Zaragoza (orcid)0000-0003-2713-2786 Martín Gil, Jesús Torres Sánchez, Sergio Casanova Gascón, José Universidad de Zaragoza (orcid)0000-0003-3009-0935 5011 500 Universidad de Zaragoza Dpto.
