Please see if you can give me a suggestion on this disease that is hitting our spring planted peach tree. I took leaves of it down to our local nursery where I bought the tree when the disease first started showing up and they couldn't ID it....I thought it was Anthracnose from research on the web but the owner of the nursery said that doesn't bother peaches.....she gave me "Copper Soap" spray and I thoroughly sprayed the tree....it is just getting worse & worse....Thank you for any suggestions you can provide....weather here was very warm for a week early in the season, then cool with rain for abit.... now it's been close to the 100's here....I don't know if weather would affect this....the apricot, cherries, and pear trees that are planted in the same grove are not affected...Deb
