Spraying for Flyspec and Sooty Blotch
I know Fly Spec and Sooty Blotch are mostly cosmetic. I know with scrubbing, I can usually wash most of it off. But, when my Granny Smith's are 80% covered with FS/SB, it means a lot of scrubbing, and I never get it all off, and thus, they're less appetizing. Yes I know, I should educate everyone about how it's just cosmetic, etc, but I've only had limited success with that. My bagging of the apples helps slightly, but not really enough. This year, I've had enough.
I currently spray dormant oil, Immunox, Triazicide, and Agristep, and I bag my apples. For the few others out there that are spraying for SB/FS, what are you guys using? I actually do have both Captan(rated as Good against SB/FS) and Ferbam(rated as Fair) lying around. Would you guys try that? Would you try the Captain? If so, schedule? Or go for some 3336 / Topsin? If so, where to get small quantities?
Thanks in advance,
