Does anyone know how long Bordeaux or Burgundy spray has to be on peaches to
give protection? I made up the copper sulphate segment of the Burgundy
spray yesterday, mixed the full recipe this morning and sprayed but we have
rain forcast in about 3 days time and I wondered if 3 days on the plants
will be enough time to work. Anyone know?

I think you are sweet. If it hasn't done the fungi present in 3 days it
won't. As for those that blow in on the wind next week that's another
matter. I do all the stone fruit at this time with copper oxychloride (very
similar, works the same way) and I only do it once. Seems to work against
peach leaf curl which is a fungus regardless of dew or rain a few days
later.

Eh? Well I guess it's nice to be called 'sweet' at least once in my life
because no-one who knows me would do that :-))

Ah! So it's a 'contact' fungicide.

I wasn't being personal You may be sweet but I don't know that. I mean
she'll be right mate. It's apples. Success is likely.

Yes but it also will stop spores getting started for as long as it remains,
so rain will reduce the long term impact somewhat.
