Thanks for the reply Deb. I thought you were the only reply. Then I 
noticed that I had been dropped from the group and I had to sign up 
again. I then checked the archives and found that Jim Freeman had 
replied also. Thanks Jim. Oh, and there's another one from Eric Hambly. 
Also helpful.
In the end, I didn't spray with Sevin after all. Imidan is also 
recommended, from what I read last year. I was spraying my plums for 
curculio anyway, so I just sprayed the apples with the Imidan too.
Another year, when the apples look too plentiful, I'll probably try 
spraying Sevin on maybe one half of a couple of trees and the other half 
with Imidan, just to see what happens. (And of course to kill the 
sawflies too.) This year looks like a light crop so it's probably good 
that I didn't go ahead with the Sevin.
