No. 4.] BUSH-FKUITS. 357 



Among the enemies of the groselles, the San Jose scale 

 should perhaps receive first mention, since it seems to be 

 very partial to the currant as a food plant. This })est is 

 now so thoroughly established and so generally distributed 

 in New Enoland that we must reckon with it as one of our 

 standing enemies. We may be fortunate enough to escape it 

 for a time, but are liable to meet it at any time. It can be 

 controlled by spraying with the lime, sulphiir and salt mix- 

 tures which are now so generally used, and by several other 

 methods. The recommended methods for dealing with this 

 pest have changed so rapidly in recent years that it is prob- 

 able that we have not yet found the best plan of treatment. 

 It is true, however, that the lime, sulphur and salt is proving 

 an efficient remedy, though one somewhat troublesome to 

 prepare. 



Currant borers sometimes cause serious injury to these 

 fruits. The only feasible remedy is to cut out and destroy 

 infested stalks. When the principle of frequent renewal in 

 pruning is followed, there is not likely' to be serious loss 

 from this pest. The older method of growing the plants in 

 tree form, with a single stalk, rendered the possiliility of 

 damage from this insect much greater than it is under the 

 present more general custom of allowing a number of stalks 

 to grow from each root. 



The currant fly sometimes causes serious trouble. This 

 insect deposits its egg within the growing fruit. The larva 

 which hatches may work from l)erry to berry, destroying the 

 appearance of the cluster, and rendering it practically worth- 

 less for market purposes. Unfortunately, the only remedy 

 which seems available is to pick off and destroy infested 

 fruits as soon as the insect is known. This, though a some- 

 what expensive process, may be really more feasible than at 

 first glance it appears to be, provided help can be obtained 

 to do the work. 



The currant worms, of which there are two species, one 

 native and the other imported, are the best-known enemies 

 of these fruits. They are, however, easily controlled.
