Shot-hole Fungus of Apricot and Peach; also Peach-curl.

The Bordeaux mixture is likewise most valuable in treatment of these diseases. The first treatment should be just when the buds show signs of swelling, again just before the blossom opens, another when the leaves are an inch long, and again a fortnight later. The rust, which makes its appearance in the beginning of autumn, giving the upper side of the leaves a yellow-spotted appearance, and the under side dotted over with small rusty-looking specks, in some districts seriously damages both peach-and plum-trees by destroying the foliage before the wood is ripe. Where this disease is prevalent the trees should receive a spraying, directed particularly to the under side of the leaves, on the first appearance of the fungus, and again a fortnight later. These sprayings are not only of service against the rust, but they also do good in destroying any of the other fungi which may have escaped the early sprayings, and which will now be forming resting-spores or seeds for the crop of next season.
