. Bulletin. Agriculture -- New Hampshire. Sl•l^\^ IN'.i TllK Al'l' OIUIIAUI). 41 rot fungi, which soon destroy it. The spots on the leaves and fruit are the source of an abundant crop of spores which are able to start the disease in new places. The fungus lives through the winter in the fallen leaves, pro- ducing another form of spore in the spring. These spores are carried by the wind to the young leaves and the disease starts anew. Some varieties of apples are affected more often than others, the Fameuse and Mackintosh Red being especially susceptible and ahnost always scabby unless sprayed. In comparisons made in the orchard of Prof. F. W. Hooper at Walpole, N. H., in 1906, we found that on the Mackintosh trees not sprayed 43% of the picked fruit was scabby, while on those sprayed twice with Bordeaux mix- ture, but were scabby. The photo of the amount of scabby and clean fruit on two of the sprayed and un- sprayed trees shows the profit from the spraying. Fruit Spot.—Several varieties of New Hampshire ap- ples, especially the Bald- win, are seriously affected by a fungous disease known as the "fruit si)ot" or "brown ; When the apples are near- ly mature small depressed spots begin to form on the surface. On the greoii parts of the apple the spots are deeper green; on the red portions, a. Fig. 27.—" Fruit spot" on Baldwin. deeper red. The tissue immediately beneath these spots is brown and corky. In storage the spots often become larger and more sunken, but are never over one fourth an inch in diameter. Spraying with Bordeaux mixture greatly re- duces this disease, the late applications seeming to be most effective. The following data show the results obtained in the station experiments made in the orchard of Mr. Albert.
