Ruggero Osler, has been a National Research Council (CNR) researcher at the University of Milan for the Plant Pathology Institute, a Visiting Scientist at the University of California Berkeley, and a Plant Pathology Professor at the University of Udine. He studies innovative strategies to increase resilience in cultivated plants and to contain plant epidemics.
He has published over 250 articles in which he proposes actionable solutions for farmers; including functional solutions for viral diseases, such as Rice Yellows; and indirect/direct Recovery techniques against bacteria called phytoplasmas that cause Apple Proliferation, ESFY (European Stone Fruit Yellows), and Flavescence Dorée of the grapevine.
He began his viticulture research in sanitary clonal selections, and then subsequently opted to focus on population selections, ultimately concentrating on the fittest grapevines, produced by Darwianian natural selection, those with effective transgenerational acquired/induced resistances and tolerances.
