I started the discussion...I didn't WANT to mix captan and sulfur, but I ran
out of captan and so switched to sulfur.  I rinsed the sprayer first but
since some trees are close together, there was some small amount of
overspray and some branches got some of each.

No big deal, I'm sure.

I did manage to get in my petal fall spray in tonight.  The weather is
funny, it has been cool. There are small apples, but too small yet to bag.
I don't see any curculio; I think it has been too cool for them to emerge
yet. 

Thanks for all the comments.

Mark,

Yeah, you are right,  but combinations of captan and sulfur can cause
necrotic spotting on leaves of susceptible varieties (e.g., Jonathan,
MacIntosh), so I usually tell growers not to mix the two.
Captan is more effective on scab than sulfur anyway, so I'm with you....I'm
not sure why anyone would want to do this anyway.
