I've been getting conflicting advise dormant spray for peach, nectarine,
apricot etc. I was told that sulfur is bad for apricots but that copper is
OK for everything. My questions:

1. Other than for apricots, is sulfur better than copper? What's the
difference in using one vs. the other?

2. Why is the recommended mix more concentrated for sulfur (4 oz per gal)
than for copper (4-5 tbl. per gal.) ?

3. Some of the trees show little drops of sap on the trunk and some
branches. What the best remedy for this?
