yes, the active ingredients - Iprodione (AquaFlo) and Strobilurin (Scorpio) are available in the U.S But those two named products are not available in the U.S and aren't listed as being effective against botrytis convoluta, probably because the two active ingredients haven't been tested against this particular pathogen but because of their systemic action they'd be very much worth investigating.
I appreciate the head up, and will do more research on these two active ingredients
