> the sulfur your notes refer to is micronized sulfur a powder not the same thing as lime sulfur
> Summer sprays cannot combine oil and sulphur (or lime-sulphur) since the combination is phytotoxic. But there are no leaves in the winter so they can be combined then.
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!
> I am curious about how people time their dormant sprays. I do only one spray and feel like it is best to spray as late as possible, just before the leaves come, so the bugs have started to wake up a bit and will be more vulnerable. I think I read something to this effect at some point and it sounded convincing. I think this stage is called "bud swell", before "green tip".
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.
