white roses for a no-spray garden?

Two roses that I'm curious about, how resistant to disease are

-Fair Bianca' and

- 'Blanc de Vibert'

I love them both but I don't spray and so I need to buy the healthiest of the two.

Where I live about a mile from the San Francisco bay, conditions favor powdery mildew for c.8- 9 months of the year and blackspot 3-4 months out of the year. To make it clear how bad the p.m. gets my Ducher defoliated and stopped blooming, and its on the Earthkind list for disease resistance (in Texas) which goes to show... location location location is everything...

We have heavy clay soil which I amend well with compost, manure et cet.

My no-spray white rose list includes:

Lamarque'

Westside Road Cream Tea' I love this so much that I bought two of them. As fragrant as Ducher but far healthier where conditions favor p.m..

'Sombreuil' an easy low-care climber, here.

'Pax'

'Mme. Jules Bouche'

Nastarana'

White maman cochet. (pink guard petals)

Little white Pet'

Iceberg'

Borderline disease resistance;

My 'Mme. Alfred Carriere was covered with powdery mildew most of the year, as is my neighbors' Devoniensis' but neither defoliate from this disease.

'Prosperity' I got rid of this for two reasons, too Hybrid Tea for me, and moderate blackspot . I did love its fragrance though and kinda miss it for that.

Which are your healthiest white roses? and do you spray?
