Default Peach leaf curl - copper or sulfur to treat?

Did you prune these trees? How?

Did you mulch these trees? How and with what?

Did you plant the tree? How?

Did you apply N? If so how much over what area?

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

I have a copper based fungicide, and a sulfur based fungicide. Both claim
to be the definitive cure for peach leaf curl. Does anyone know which works
better, or if both are equally effective? Last year my peaches had peach
leaf curl quite severly. I'd like to prevent it from happening this year.
