The amoimt of damage done by this disease varies consid- erably with the season. In some years seventy-five per cent of the crop is destroyed. In New Jersey the annual loss to cranberry-growers on account of scald is estimated at about one-third of the crop. Symptoms. The berries, flowers, leaves, stems and roots are affected. The first evidence of scald appears as a minute, light-colored, watery area on the surface of a berry. This enlarges until the whole berry is involved, softens, and turns brown (Fig. 52). It is thought that in the East affected ber- ries do not turn brown, and that this character is influenced by the soil and climatic conditions. Sometimes several spots develop on a single berry. Finally, either the whole affected fruit assumes a scalded or cooked appearance; or, in case only a portion decays, the berry shows a concave surface on the affected side. The interior of scalded berries is soft and watery. It is sometimes difficult to say whether a berry is affected with scald, for although it appears healthy it may still be diseased. Berries when affected before they are one-half grown usually hang shriveled, and covered with black dots — the fruiting bodies of the causal fungus. Dark concentric rings often show; however, this is not a peculiarity of scald, for it does not occur constantly, and furthermore.
