Peach Leaf Curl

[coach]

My peach standard has peach leaf curl and has for the last 5 years!
Does anybody know how to prevent it?
I spray it in Autumn and Spring with Bordeaux Mixture and I cover it over winter.
Any help?

Hello, and welcome to the Vine I have never managed to stop peach leaf curl yet. I do the same as you but I still get it every year and it is now at the point where it has really weakened the tree. Can you get hold of some good manure for the roots, that might help otherwise, I'm afraid, I'm stumped.

I bought a dwarf standard tree which I keep in the poly tunnel almost all year on the understanding that PLC is in the rain. I know people who have them growing against walls, construct a plastic cover which goes on over winter.

EDIT my original link was incorrect - apologies - use Martin's below to the RHS site.

Some one who knows something will be along soon.

The RHS don't mention this on their page Organic Disease Control For Peach Leaf Curl though.

This is the RHS page: https://www.rhs.org.uk/Advice/Profile?PID=232. It explains using a plastic cover.

We never had it on our young tree when we kept it in the greenhouse.
As soon as it was planted outside we got it.
I've tried spraying it with Bordeaux mixture in the autumn and spring and every 2-3 weeks to the point the plant went blue and it still didn't stop it.
The only thing I haven't done is use plastic sheeting, but that's not possible where it is situated.

I think it's trying to tell me it really doesn't suit my growing conditions I'm offering it.

I keep giving it another year but after about 7 years with only a few peaches the first year I think it's a waste of space.
Pity really.
I think I will dig it up and pass it on to someone else to see if they can make it happier than me!

And so- after all that natter- I'd say that if you can't offer a greenhouse to keep the rain off, then I'd certainly say go down the plastic cover route! Not pretty though I'm afraid.

I think the problem is that we're trying to grow something which is more Mediterranean in an area too damp/rainy and cool??

Spraying is both a waste of time and money.
You need to construct a shelter to keep the rain off throughout the late autumn and winter, but allow access for pollinators. Similar to the picture in the RHS website, as linked in Martins post above.

in the greenhouse didnt have a probelem, outside it is, spray or not, but I do get fruit, just rubbish leaves

I am trying some new things.....

net bag ( like onions come in ) with crushed raw egg shells in....hang in a tree.....did and the ones I dd it to are almost healthy and i did nothing else

There is a fairly new patent about leaf curl cures, seems oregano and thyme oil work well, even after a tree is infected, one tree I sprayed once looks a bit healthier after the oregano oil but I ran out so waiting for some from ebay, cant see why it wont work....many natural things tend to work quite well, the claim is it helps even after infection unlike other sprays , bit long winded but jump to the detailed description half way down...

basically....mix something like 2 ml of oregano or thyme oil into litre of water of (probably use a drop of dishwash liquid to emulsify) and spray tree....

Method for treating peach trees for peach leaf curl disease - BECKER JACK L.

Quote:
several (e.g., two or three) heavy doses of Carvacrol by way of oregano oil (sold commercially as Oil of Oregano) or thyme oil (sold commercially as Oil of Thyme) to the infected trees has been found to cure the trees without the use of chemical fungicides. A solution containing about 6-7 ml Oil of Oregano or 7.5-8.5 ml Oil of Thyme and one gallon of water can be sprayed onto the infected trees to kill the fungus so that new leaves will retain their full green color and blooming buds will blossom into fruit as if no infection had occurred.

^^^ sounds interesting!

Certainly worth a try!

leaf curl

Hi
many years ago l had the peach tree peregrine growing on the wall in the background of this photo
at that time the lean to did not exist just the fan triand tree, l always got some some fruit and some
leaf curl, l would remove the curled leaves and plod on.
Now l have my dwarfe peaches covered l am having much more success.
Speaks for itself l suppose, peaches in my climate need to grow under cover.
kind reg

Those look really healthy!

Peaches in any climate are easier under cover, but over here in Bulgaria everyone grows peaches, orchards full of them everywhere, gardens full of them as well, they all get leaf curl if not sprayed regularly unless covered

there are so many gardens that nobody uses any more full of them loads of places for it to spread from

My outdoor peachs in the UK are not often affected but it was not at all affected untill aldi started to sell cheap �3 peach trees that nobody sprays so now lots of places for leaf curl to spread from

In Bulgaria nobody ever covers the trees as they are too big, most times grown as 20 foot+ high high trees ,leaf curl is just always there, with a big in ground tree there is no way to cover it so people just spray everywhere using mainly copper/lime , sprayed at the right time it usually works very well but once infected it has no effect, so I am hoping the oregano oil does its tick and it did have an effect

The egg shells in nets.....seem to work quite well....I presume sulfur is given off from them over time?

[BUFFS]

who would have thought that the aldi peach, "red haven", @ �3.99, would be the recommended one (by RHS) as being resistant to peach leaf curl, mine is 5 yrs in its pot and @ 4ft tall, from soil level, it is carrying about 35-40 young fruit at the moment so we are looking forward to the crop....
