Got it. There seems to be a bit of disagreement here, but the end result 
is the same (at least for dormant spraying) - that I don't have to worry 
about combining lime sulfur and dormant oil. Thanks much!

That would sound good to me, too. As I mentioned, I'm mainly concerned 
that I don't encourage the breaking of dormancy - and the resultant 
blooming - any earlier than I have to.
