Browning of European Pear Leaves: I am experiencing a foliar disease on an European pear. The variety is Starking Delicious which is meant to be fire blight resistant. I follow the MD extension service schedule for regular preventative spraying of pear trees with fungicides, using Mancozeb in early season and then Captan in the summer cover sprays. In early July 2012 leaves on the tree started to become brown, with maybe 70% infection rate by the end of July. The infected leaves hang on the tree for a considerable period after they become brown but they do eventually fall off. The disease was not obvious in 2013. In July 2014 I am again starting to see the same browning of some leaves. The browning of the leaves certainly resembles fire blight. However, I am very familiar with fire blight as 2012 and 2014 were bad fire blight years on some of my apples. I have been pruning out fire blight infected small branches from my apples since about two weeks post-bloom but the pear tree leaves have looked very healthy until early July. If my pear was infected by fire blight I think I would see some symptoms of "wilting" of young shoots but I saw no evidence of this in 2012 and none this year. Furthermore, the leaf die back with fire blight also generally starts at either a flower spur or the tip of the new shoots but with this pear tree there is no pattern to which leaves on the branch are starting to brown off. There is no evidence of any of the fruit shriveling as occurs with severe fire blight. Also, on my tree the discoloration in each leaf is initially very localized within each leaf. This seems more a characteristic of a fungus. With fire blight the entire leaf seems to discolor more uniformly throughout the leaf. I have an adjacent younger pear tree of the same variety and it is not affected at all. So it is odd that the disease is not infecting the other trees. I do not think that this a response to drought as 2014 has been a wet year. The soil is a well drained sand so the tree is not responding to a waterlogged soil Thanks for your help
