Many ex- periments have demonstrated that this scab-produc- ing fungus can be kept down by the use of the Bordeaux mixture and various other similar substances. The fun- gus thrives below the skin of the fruit and the epider- mis of the leaf, producing spores in abundance upon the surface. The fungicide, when left in a thin film upon the susceptible surface, prevents the germination of the spores and the extrance of the fungus. It likewise may kill the spores in the places where they are formed and before they have been transplanted to another part of the plant. The fungicide cannot act as a cure in the sense of replacing the diseased,by healthy tissue, but may, by destroying the prevent the spread that the healthy parts may predominate. In the case of foli- age, the spraying is chiefly preventive, and should be particularly directed to the younger leaves, the older ones, with the fungus already established in them, in time falling away. With the ordinary fruits there is no ,=^^. 723. Effects of the leaf-curl fungus on peach foliaee (X X). such succession, and the aim is to have each apple or pear coated with the fungicide. As a rule a fungus that attacks the fruit also infests the leaves, and may likewise thrive in the stems. From this it is gathered that the spray should be very thoroughly applied to all parts of the plant, in order that the foliage may be kept in vigor and make the required food sub- stances for the growth of the fruit, and the latter saved from decay due to direct attack of
