Paul,

The only approved sprays for Peacock Spot or copper sprays, either copper
hydroxide or copper oxychloride. Both are more preventative than curative,
so I'm a bit dubious how effective they would be. I'm pretty sure they are
both approved by the organic people.

I believe Mancozeb is an effective curative, but isn't approved for use on
olives. Damian Conlan from NSW Dept of Agriculture is well up on this sort
of stuff.

I have managed to bring Peacock Spot under some sort of control using copper
hydroxide (in the Hunter, glad to hear you enjoyed the conference) but it
did take 3 sprays over a period of months to knock the infection down to
manageable. Timing is important, and a spray now is vital to inhibit spore
growth with the spring flush.

Regards,

Mike Wilson.
