Remedies.—This fungus is closely related to other anthrac-noses previously considered and may be controlled by theuse of the standard fungicides. The Leaf Spot {Septo?-ia ribis Desm.) is a fungus that pro-duces effects similar to those of the anthracnose, while itsmicroscopic structure is quite different. Remedies.—Spraying should be thorough and begin early inthe season. The currant is well adapted in size for the ap-plication of fungicides, and any adhering lime upon the smoothfruit is easily removed. To avoid this coating a clear mix

The Gooseberry.—The diseases of the currant are practi-cally the same as those of the gooseberry, and all that has beenremarked above regarding them generally applies here. 238 THE DISEASES OF FRUITS. The Mildew {Sphcerotheca mors-uvce Schw.) is a fungus thatis very destructive to the gooseberry, but is rarely met withupon the currant. The European varieties are particularly.

This mildewproduces a felt-like brown coating upon the young growth ofstems, including the leaves and fruit, which are much dwarfedand distorted.

There is a second form of spore produced inspherical thick-walled bodies, designed for preserving themildew through the winter. These form later in the seasonthan the small naked spores previously mentioned. Remedies.—Satisfactory results are obtained from sprayingthe gooseberry plants, partly because the mildew is upon thesurface only.
