Hi Col - it looks like it still has leaf curl. Someone will know more about this than me.

But - are these pics of the current growth?

Do you only spray at bud swell?

I usually do my trees twice in winter - the first spray at leaf drop - getting right into all the nooks and crannies and bark. Then one at bud swell.

Have a look in the search function (top right hand corner of Forum main page) under "leaf curl" also...the thread 'Spring Sprays" may also be helpful.

This link may help too - it does say that once the fungus is inside the leaf then there is no treatement....

Hi Amanda
I usually spray once a year.
I know it still has leaf curl, but I'm more concerned with the leaf drying & been crumbly.
Also note the stem spots in Pic1 and the brown center in pic5.
Some branches are bare and dry.

I love your "garden".
Got to fly in a few hours to Perth and your home town.

Anyone else have any ideas here?
Col - it's really hard to say if the problem is due to the leaf curl or maybe even black heart/something else?

Try gooling - black heart disease in fruit trees - and see what u think - and here is one short link:

http://www.sardi.sa.gov.au/pestsdiseases/horticulture/horticultural_crops/apricot_pests__and__diseases/black_heart

The leaves look very burnt - but this could be due to disease or fertilisers/sprays... you may have a better feel for this?

Either way it's not looking too good hey. :-(

Sorry I may not have much help to this but dry leaves like that makes me feel like it is chemical burns...did you fertilise it? Heavy fertilsing can kill it too...

I think peach trees are very good with frost and cold so doubt it is due to that.

Looks like dead arm -a fungus infection requiring radical pruning and sterilise secateurs after use.
