. Fig. 56.—Pear stigmonose, sections of affected fruit. Scab.—The first symptom is dark, velvety mold patches, consisting of the fungus Venturia pyrina, on young fruit and leaves (fig. 10, p. 25). Fruit badly affected by this fungus drops; on that which remains, the dark areas become hard, rough, and cracked, and the fruit much de- formed (fig. 54). Spray with lime-sulfur 1-50 (p. 160) or bordeaux mixture 3-3-50 (p. 156) just as the cluster buds first start to open. Eepeat just before the first individual flowers open and, in severe cases, again as the last of the petals are falling. Bordeaux

Bordeaux mixture—applied early in the blossom period—is sometimes beneficial in reducing blossom blight.
