Temp in upper 90s, is it too hot to spray for BS?

Our temps have been in upper 90s past few days and it looks like it will continue. My roses have some black spot, it is so humid here, and I am wondering if it would be ok to spray with Bayer Advanced with the high temps? Any suggestions? I have been picking off BS leaves but they really need sprayed. Thanks.
