I tried @JoeReal’s Italian salad dressing spray couple of times during the dormant season. I didn’t have any PLC when the peaches leafed out but reading CRFG emails, others in the area who didn’t spray at all didn’t have it then either. After a spell of dry season and rains, I got hit badly (others too) but observing the tree, I think it was concentrated on a couple of my grafts (which were not likely sprayed) and mildly spread to the rest of the tree. So, hard to say anything about the effectiveness of the spray. I’ll try the same procedure again and observe what happens.
Octoberfest sounds very interesting. I have my eye on it for next winter order. @RandallW What are your fav peaches/nectarines so far?
