This Leaf Spot disease of gooseberry (Fig. 58) is the same as that found on the currant. It prevails to some extent in America wherever the host is grown, having been reported from at least ten states over the northern half of the United States. It is probably most important in Ohio, New York and Iowa, where defoliation of affected gooseberries may be more extensive than of the currant. This may take place before maturation of the fruit, in which case the berries wither and are rendered worthless. Native gooseberries are injured more than other varieties; this is true in New York at least.
The control of this trouble is said to be accomplished with more ease than in the case of the same disease on currants. For the schedule of remedial measures, see Currant, page 205.
