(Geneva) Bulletins 163 and 185, or Ann. Reports 1899 and 1900.) The Blight Canker.—This is a common canker of apple and pear trees in many parts of the State. The blight cankers are caused by the bacteria of Fire Blight and are but another form of that dreaded disease. They usually appear on the body and main limbs of young apple trees just coming into bearing. They usually appear about the base of short spurs or water sprouts which have been blighted, the bacteria work- ing their way down into the bark of the limb. (See Fig. 366.) This canker diflFers from the New York Apple Tree Canker in appearance, being smooth and sunken with a distinct crack marking its boundary. It is not black, the diseased area being about the color of the healthy bark. It is in these cankers that the bacteria are carried over winter, especially those on the pear tree. From these "hold over" cankers as they are called, the bacteria are carried in the spriner to the blossoms and twigs by bees, causing blossom and twig blight. Now is the time to tackle this disease. Cut out and treat the cankers as described for the New York Apple Tree Canker above. Spraying the trees, after the cankers are removed with lime or sulphur wash or strong, Bordeaux may also be of some benefit. (See N. Y. (Cornell) Bulletin 236.)
