Too late to treat peach leaf curl?
 

When I moved here there were two dwarf peach trees. They have generally
been susceptible to peach leaf curl, and I suppose that's the reason
that one tree died. The other seemed to die, but sent up shoots from the
root area and now is alive, although not doing too well. Still, I got
maybe 3-4 quarts of little peaches each of the last two years or so.

We had an exceptionally rainy spring here in Berkeley, CA this year and
the surviving dwarf peach tree has terrible peach leaf curl. Almost all
the leaves are yellow and badly deformed. The only leaves that look OK
are very small and rather rare. I've never treated the tree, although I
have a plastic bottle of Chacon Bordoil copper-oil fungicide that I
purchased some 20 years ago (and never used).

So, my questions a

1. Is this Bordoil peach leaf curl treatment still usable, and is it a
wise choice for treating the condition?

2. Is it at all possible to do something to alleviate the condition at
this point in time, or do I have to wait for fall or winter?

Thanks for any information.

Too late to treat peach leaf curl?
 

The only effective treatment of peach leaf curl that I have used in
fungicide applied during dormancy. Ferbam after leaf drop or just
before buds swell. Severely infested trees both fall and late winter
applications are recommended, I also use lime and sulphur and dormant
oils for other problems but it did not suffice for peach leaf curl.
