Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 1244 PEAR PEAR. 1684. Cluster of Pear flow^ers. with two or three exceptions, are not verj' serious. The tree is attacked by borers, although to a less extent than peaches and apples. These are kept in check by digging them out once or twice a year as on other fruit stocks. The fruit is attacked to some extent by the codlin-moth, but the arsenical sprays keep this insect in check. Of late years the psylla. attacking the growing parts, has been serious in parts of the East, al- though it is very irregu- lar in its outbreaks. It can be controlled by thor- ough work with a spray of whale-oil soap, one pound in three to five gallons of water, begin- ning soon after the fruit has set, and repeating the application whenever the psyllas become nu- merous. In some parts of the East the fruit is attacked by the Pear midge, a minute fly whose maggots work in the very young fruit. Thorough cultivation will check this seri- ous pest, but its complete control often involves the destruction of all the young fruit on the infested trees; in some sections the application of kainit to tlie soil is said to kill the insect after it leaves the fruit to un- dergo its transformations. The foliage and fruit of the Pear are attacked by para- sitic fungi, which cause the leaves to drop and the fruit to become scabby. These diseases are readily held in check by spraying with Bordeaux mixtiire. Fifty years ago the White Doyenne Pear was the most popular va- riety for growing on the quince root, but because of the Pear scab it passed away. It was supposed that the disease was due to uncongenial climate. Since the ad- vent of the sulfate of copper sprays, however, it has been found that the White Doyenne can be g
