nectarine tree has white powdery substance and oozing sap

[jim rossman]

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.)

Thanks for the info!!

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?
