Neem oil doesn't work and it makes your roses a mess. Theo is
right--it burns. Why aren't you using an effective systemic like
Orthenex? The bs you have will defoliate and weaken your roses and it
does indeed encourage canker. I have maybe 5-10 JBs a year, and see
them staggering around on the ground after a few bites.

My roses suck right now because I have not had a dry enough period or
time to spray them since mid-May, but they surely do not look as bad
as yours. Except the ones that are totally naked.
