Dr. t'lus said thai this was the worst problem that pear growers have to contend with. It Las been known to sweep Lhrouuh entire fruit sections and entire states causing loss- of many thousands thou-sands of dollars. The organism eausini: the disease is known definitely defin-itely to be a bacteria, and it is rallied from tree to tree by bees and ot her insects at blossoming time. Oregon and Washington states have "pear blight" inspectors who are trained to detect the dise i-e instantly and have authority to enforce en-force its clean up. If it were not for these riiritl measures, Oregon and Washington wuuld have been out of the pear growing business Ion;; a so. The most discouraging part of fighting "pear blight" is there are always careless neighbors neigh-bors whose trees are a constant menace to the community. A county-wide county-wide movement is the only sure way of eradicating the blight. Pear IJlight Schools In Michigan, "pear blight" schools are established among the farmers. There they are taught to identify bacterial cankers and to carefully cut out and disinfect them. f The three control measures are: Prune out dead limits six inches below lession and carefully scraie out cankers on large limbs, and disinfect dis-infect them with one part mecuric bichloride, one part cyanide of mercury mer-cury and 50U parts of water. This material can be purchased at any drug store. Add a little Diamond dye to give red color. This makes it easy to see where the trees have been treated. Prune during growing season. Special attention should be given shortly after blossoming time. Either disinfect the tools or the wound. Hold back the growth on the tree, for where the tree grows vigorously, the blight also grows vigorously. A young Martlet t pear tree should make an annual growth of from (i to S inches' instead of 2 to 'A feet. In-. Clos spoke on the cherry situation sit-uation in the county.
