Situation of the breeding of fungus-resistant Portuguese grape varieties with  Jorge Boehm Portugal

While science in the Germanic countries has been successfully experimenting with the introduction of resistance to mildew and downy mildew in grape varieties since the 1960s and 1970s, the Mediterranean countries have only recently become aware of this new type of ecologically sustainable vine, after the first interspecific variety was officially recognized for wine production in the EU in 1996.
(Repetition because not feasible at the last summit for technical reasons)

Optimizing plant protection for PIWIs

Despite the tolerance and low susceptibility to fungal diseases, targeted plant protection plays an important role for PIWIs. This input focuses on general and specific possibilities to optimize plant protection measures.
