To prevent mildew, both currants and gooseberries were sprayed on the 

 ■22d, using 3 oz. potassium sulphide in ten gallons of water. The same 

 preparation was again applied on June 1. 



Mildew was discovered on the foliage and fruit of a single plant of 

 Triumph gooseberry, the plant being under the lee of an evergreen screen. 



Sprayed currants and gooseberries with potassium sulphide on June 

 20, and, aphides having appeared on several plants, these were also 

 ^sprayed with buhach in water. This not proving sufficiently effective, a 

 second spray was given June 25 with strong tobacco water, care being 

 taken to apply it to the under sides of the leaves. 



June 27, again sprayed currants and gooseberries with tobacco water, 

 ior currant worms. 



June 29 repeated the same. 



June 30 repeated the potassium sulphide spray for mildew. 



July 14 repeated the potassium spray on gooseberries and currants. 



July 28 gave currants and gooseberries a final spray of potassium 

 flulphide. 



The fact that the Paris green and buhach were less effective than was 

 anticipated, may probably be charged in part to the occurrence of rain; 

 and, perhaps, in part, to adulteration of those insecticides. The tobacco 

 water was prepared on the premises, and proved quite as effective as the 

 other applications. 



With the exception of the cases already noted, no other important insect 

 or fungous depredations have been observed, except that, in the effort to 

 suppress the twig borer, considerable bearing wood has necessarily been 

 sacrificed.
