Ampelinum ) known as an- thracnose . It first appears on the shoots, leaves, and berries of grape-vines as minute brown spots which are a little depre ed in the middle and have a slightly raised darker-colored rim. These spots soon increase in size and elongate longitudinally. On the fruit the spots retain a more or le regularly rounded outline, and have a well- defined band of bright vermilion between the dark border and the central portion. Finally, under the action of the disease, the berries dry up, leaving nothing, apparently, but the skin and seeds. Washing the vines with a strong solution of sulphate of iron before the appearance of the leaves has been found effective in destroying or checking the disease. See anthracnose.
