Glad to hear it is working for you so far!
Brown rot often shows up at ripening so I would keep my eyes out for it. Especially because you are not using any synthetics it can really come out if we get a lot of rain. So, I would definitely keep spraying for it.
Apple rots usually show up later, I often think I am clear and neglect to spray and get some rot. Which reminds me, I should spray my apples again soon. I have only done one spray since mid-June. They only need one more spray; I will also hit the later peaches and pears at the same time.
