226 MANUAL OF FRUIT DISEASES 
LEAF-SpPorT 
Caused by Mycospherella Grossularie (Fr.) Lind. 
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 re- 
ported from at least 
ten states over the 
northern half of the 
United States. It 
is probably most 
important in Ohio, 
New York and 
Jowa, where defo- 
liation 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 worth- 
less. Native gooseberries are injured more than other varie- 
ties; 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.
