Thank you Larry,
I noticed that it started on few of my roses, I have the spray but wonder if anybody have better idea that do not involve chemical...
This is part of an article at Gardenguides.com, anyone tried these ?

"Alternative Fungicides
Alternative treatments to traditional chemical based fungicides to help stem the advancement of black spot include lime sulfur, neem oil, hydrogen dioxide, potassium bicarbonate and copper products. These can be applied as a liquid spray."

Thanks,
