Natural Fungicide for Peach Leaf Curl?

I’m looking for a home grown treatment for peach leaf curl on my nectarine. The tree is about 3 years old and only about 7 leaves survived this year. I tried spraying garlic concentrate last fall and early this spring but maybe it was just too rainy.

I was just reading an article about horsetail being a good fungicide for peach curl, and then also thyme oil apparently works on fungus too. So I was wondering if anyone has experience using any of these for peach leaf curl…or a combination? I’m thinking of making a batch of horsetail and thyme tea and then adding the garlic and letting it sit overnight. Is this overkill? Will they cancel each other out? Will this work on rust spots on my pear too? Thyme is also an insecticide so should I omit the thyme? I also have soapwort, would that help?

Any advice is appreciated! Thanks

bonide copper fungicide is a certified organic solution for treating exactly what you describe. removing any dead leaves or decaying organic matter from under tree seems to be very important if you have such problems or sometimes its described as keeping  your orchard sanitary.
but maybe there are some other ways folks have found to control such problems in stone fruit trees that are in forest gardens and such.

Not sure if this will work for you, but I tried a remedy I found somewhere online (here?) that seemed to have worked for me (fingers-crossed) ...the 'cure' involved taking some copper (I used old 1/2" copper pipe that I cut into 1/4" pieces) and bury it in the ground around the tree. Then take some egg shells, unwashed, and hang them in the tree (I used an old onion 'net' bag) ...I totally didn't think this would work, but swear to God this is the first year my peach leaf curl problems have abated. I had to pick off & dispose of a few offending leaves early in the year, but the tree is looking its best since I planted it. I didn't get any peaches this year, but would recommend giving it a try next Spring and would be interested to hear if it worked for you (or not).

best,
