I've had good luck with the Bayer fungal prevention, but it doesn't do very
well on active block spot. Mancozeb and Pentathlon both are more effective
at addressing active black spot. (Checkout Rosemania for details) Also, I
prefer to Bayer's spray fungal prevention (Disease Control) over the stuff
you pour on the ground. That may be 'cause I'm old and don't know any
better.

Best Regards

Jeff

I have black spots on mt roses and have been using the Bayer Rose stuff,
says it protects from the inside out. It seems to help a little but does
it really work? Anybody ever use this stuff?
