Hi Bill, thanks for that .pdf, it does look like a good resource on a lot of topics. Researching on the web I noticed that Powdery Mildew is species specific, i.e. powdery mildew from on an apple tree is not the same powdery mildew on squash, nor is the treatment. That .pdf talks about powdery mildew treatments for cherries, peaches, apricots but I didn't see a discussion on treatment for apple (other than apple toxicity comments for chemicals used for the other fruits). I guess I need help interpreting what to use on apple. Thanks, Rye Hefley Future Farmers Marketer So.

So I looked it up and low and behold they have powdery mildew. The coating is not as thick as the worst picture I saw on the web, but the coverage area is a lot, i.e. it is worse than just splotchy. Of course I aim to eradicate the problem on those trees but also don't want it to spread to this years planting. Yesterday I pruned off and discarded as much of the infected wood as I could. I plan to hunt down some Serenade today. The trees don't have any leaves yet and the recent planting only has leaf clusters on the variety that "woke up" in the nursery. I'm anxious to start spraying as soon as possible, so my question is: Is it good to start spraying now when all there is to spray at this point is wood? Thanks, Rye Hefley Future Farmers Marketer So.
