When I planted my two Asian pear trees about 20 years ago, I had real hell because my back yard soil is heavy clay and I dug little and filled with water, waited over night, dug more and filled water. I repeated this for many days and finally dug up enough depth to plant my two pear trees. About 10 years ago these pear trees had fireblight disease and I needed to remove many affected branches to save these trees. Year after year, these trees gave us more than enough juicy sugar sweet delicious pears but now all leaves of these trees are curled and miserable looking fruits are size of US quarter coin. About this time of the year, we always harvesting beautiful fruits and shared with our neighbors but not anymore. I am so disappointed and desperately trying to save these trees. Sorry for my poor English. English is my second language. P.S. When I was doing research on Asian pear diseases, I found this link and leaves on my Asian pear trees looks exactly same as pictures in link below. http://plantpath.caes.uga.edu/extension/plants/woodyornamentals/PearEntomosporiumLeafSpot.html Now, what kind of fungicide is best for my Asion pear trees? I need organic safe fungicide.
