nectarine tree has white powdery substance and oozing sap

I deep water my Nectarine tree once a week. I have not had any problems the last two years. I now have a white powdery substance on most all the new fruit and lots of them are oozing with sap. What can I do to get rid of this :?:

I don't have fruit trees myself, but at a guess it sounds like powdery mildew. Does it look like this:

If that is the case, it is a fungal condition. I would get rid of all already diseased fruits and then spray the tree with either a milk solution or a baking soda solution. (Put milk treatment into the search the forum feature if you aren't familiar with it.)

OOzing with sap?

When you full off the fruit cut some open - look for larvae that are eating their way into your fruit - which can open them to mildew etc.

Clean up the oozers or you may soon have ants and aphids.

Did you use an oil spray early this spring?
