ABSTRACT
The article discusses the benefit of early copper application for disease control on apples. The author explains that the positive disease-control benefits of coppers on apples are counterbalanced by the phytotoxicity risk to trees, particularly through russeting of apple fruit. The fire blight pathogen Erwinia amylovora and the apple scab pathogen Venturia inaequalis are highly sensitive to copper. Application of coppers is to be done immediately prior to the trees breaking dormancy.
