Potential control of forest diseases by solutions of chitosan oligomers, propolis and nanosilver 2018 Access copy available to the general public Unrestricted There is a growing necessity to replace chemical agents with ecofriendly materials, arising from the impact on the environment and/or human health, which calls for the design of new broad-spectrum fungicides. In this work, chitosan oligomers (COs), propolis (Ps) and silver nanoparticles (AgNPs) mixtures in solution were assessed to control the growth of different phytopathogenic fungi and oomycetes in vitro. Binary solutions of COs-Ps and COs-AgNPs evinced the highest antifungal effect against Fusarium circinatum and Diplodia pinea fungi, respectively, with a ca. 80% reduction in their mycelial growth. The COs solution by itself also proved to be greatly effective against Gremmeniella abietina, Cryphonectria parasitica and Heterobasidion annosum fungi, causing a reduction of 78%, 86% and 93% in their growth rate, respectively. Likewise, COs also attained a 100% growth inhibition on the oomycete Phytophthora cambivora. On the other hand, Ps inhibited totally the growth of Phytophthora ×alni and Phytophthora plurivora. The application of AgNPs reduced the mycelial growth of F. circinatum and D. pinea. However, the AgNPs in some binary and ternary mixtures had a counter-productive effect on the anti-fungal/oomycete activity. In spite of the fact that the anti-fungal/oomycete activity of the different treatments showed a dependence on the particular type of microorganism, these solutions based on natural compounds can be deemed as a promising tool for control of tree diseases. info:eu-repo/grantAgreement/ES/MINECO-FEDER/AGL2015-69370-R info:eu-repo/grantAgreement/EUR/COST/FP1406-PINESTRENGTH info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.744 2018 HORTICULTURE 9 / 35 = 0.257 2018 Q2 T1 AGRONOMY 30 / 89 = 0.337 2018 Q2 T2 PLANT SCIENCES 98 / 228 = 0.43 2018 Q2 T2 0.709 2018 Agronomy and Crop Science 2018 Q1 Plant Science 2018 Q1 Horticulture 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Martín-García, J.
