In this work chitosan combined with the biocontrol yeast Debaryomyces hansenii F9D was tested as a safer alternative for its control on cold-stored apples and pears. When medium molecular weight chitosan was applied on fruit a reduction of rot incidence of 62% and 53% was achieved in apples and pears. respectively. When chitosan was combined with the yeast, disease reduction was 76% and 90%. The combination of biological control with chitosan appears as a feasible strategy for the control of phytopathogenic fungi. © 2022 Informa UK Limited, trading as Taylor & Francis Group aBiological control aBlue mold aChitosan aPome fruit aPostharvest storage aYeast1 aZACCARI, F.1 aGARMENDIA, G.1 aCASTIGLIONI, J.1 aVERO, S. tInternational Journal of Pest Management, 2022, vol. 68, issue 4: "Uruguayan Society of Phytopathology (SUFIT): Plant protection for a sustainable agriculture", p.339-348. doi: https://doi.org/10.1080/09670874.2022.2123569
