CURRANTS.— Bi&es. 



The stand of currants, having been transplanted two years since, is not 

 yet at its best, so far as the yield of fruit is concerned, while it is also 

 true, that several of the newer varieties have not yet a full stand of plants. 



On March 29th, foliage' being yet dormant, the plants were sprayed with 

 a solution of one pound of copper sulphate, in twenty-five gallons of water. 



The spray of potassium sulphide, used to prevent mildew of gooseber- 

 ries, proves effective also in preventing loss of the foliage of currants, for 

 which reason a spray of this has been occasionally applied to the currants 

 also. 



On May 29 th, aphides having appeared on the foliage of currants they 

 were treated with a decoction of tobacco stems in water, the same being 

 directed upon the under side of the leaves where only these insects occur. 



The imported currant borer — ^geria tipuliformis, which has, for 

 several years, proved a very troublesome enemy of the currant throughout 

 this region, has been persistently attacked by cutting away and burning the 

 infested twigs. This has already so reduced their numbers that a careful 

 examination, in early November of the present year, only detected a single 

 larva. 



The currant worm — Nemaius ventricosiis, appeared at the usual season 

 but yielded readily to the usual treatment with a spray of buhach in 

 water. This is considered preferable to the usual poisonous applications, 

 since it must be applied when the fruit is near ripening.
