The encyclopedia of practical horticulture; a reference system of commercial horticulture, covering the practical and scientific phases of horticulture, with special reference to fruits and vegetables;. Gardening; Fruit-culture; Vegetable gardening. 1760 ENCYCLOPEDIA OF PRACTICAL HORTICULTURE Pyrus japonica, is grown in gardens for the sake of its flowers, which vary in color from creamy white to rich red, and are produced during the winter and early spring months. The fruit is green and fragrant but quite unedible. Cydonia mau- le% a more recently introduced shrub from Japan, bears a profusion of equally beau- tiful orange-red flowers, which are fol- lowed by fruit of a yellow color and agreeable fragrance; so that, when cooked with sugar, it forms an agreeable conserve, as in the case of the ordinary quince. QUmCE DISEASES The quince is attacked by the diseases and pests common to apple and pear; and, for the most part, they will be found listed under those heads. Antliracnose H. S. Jackson Mr. C. C. Cate, formerly assistant in plant pathology at the Oregon Agricul- tural College, records the presence of apple tree anthracnose as a disease of the quince. The writer has also observed this disease upon several occasions in the vicinity of Corvallis, first in the fall of 1909. We are informed by W. H. Law- rence that he found the disease quite com- mon in the Hood River valley in the fall of 1911. It is apparently not infrequently found on the fruit, particularly in sea- sons of early fall rains. It also causes small cankers on the branches and twigs. No experiments looking toward the con- trol of this disease on the quince have been carried out, but it is probable that fall spraying with Bordeaux mixture, as for the apple, would control the trouble. Apple trees in the vicinity of quinces should be protected by fall spraying in order to prevent the disease from spread- ing to the quinces.
