If you are expecting rain then a surfactant is a good idea. Neem oil works well and so do some of the synthetic surfactants now on the market.
I don't care for several of the traditional dormant oils, especially those with distillates.
Until I began filling up my yard with 2,000 fruit trees I just used Liqui-Cop with no surfactant. My pit fruits had maybe 5% curl symptoms, where as my next door neighbors untreated trees had almost 100%. The directions are extensive -- follow them.
Nowadays I have more plants to treat and more microbes to control -- such as fireblight on my pear and quince stock. I'm going to spray with Liqui-Cop and then follow-up in a day or two with AgriMycin (license required). Then I'll come along a week later and do a pre-emptive strike for thrips with either Spinosad or the equivalent of Green Light brand Fruit Tree Spray.
Then in 90 days I'll come along again with something minor to control pest insects -- having taken care of the bulk of the problem now.
