Fortunately for the pear-grower Bitter Rot is never as common and destructive to the pear as to the apple. Whereas apple Bitter Rot ranks second in importance only to apple scab over the country as a whole, pear Bitter Rot is rare and has never been found doing extensive damage. The fungus, G. cingulata, was reported as causing cankers on both young and old trees in Texas a few years ago. Characteristics of the disease on the fruit and woody portions of the tree, together with a description of the life-history and control of the patho - gene, are given in some detail under Apple, page 14.
