Like Bart, I wouldn't want fungicides (not to mention insecticides) right outside my window or door. Remember that ". . . cide" means that it kills something.
Decades ago, when a dog we loved began to seizure everytime we sprayed, we re-assessed our priorities. We decided that roses which rusted or mildewed to an unacceptable level without spray weren't going to work for us. So . . .
If it rusts, it goes. We look for cultivars that are resistant to fungus diseases. Without sprays, we have fewer harmful insects, rather than more.
