In September 1998, the Montreal Botanical Garden (Le Jardin Botanique de Montreal) carried out a survey of its roses' resistance to black spot, powdery mildew and rust. This was one of the outstanding varieties which showed a 0% to 5% infection rate. The data were taken on well-established roses.

In recent years in some parts of the northern midwestern states of the USA, such as Minnesota and Wisconsin, 'John Cabot' has been hit hard by a variety of leaf spot diseases.
