 Apple Scab. 

 Some experiments 'wore conducted last summer with the co-operation of 

 Messrs. Wm. Ci'aig, jun., and J. M. Fisk, of Abbotsford, Que., which were designed 

 to throw light upon the following points in the treatment of apple scab: — 



1. The relative efficacy of copper carbonate in suspension and solution. 



2. The relative efficacy of copper carbonate unwashed (a modified eau-celeste) 

 in solution and in suspension. 



3. The possibility and effect of using Paris green with these mixtures. 



The results are given in detail in the accompanying table, and may be briefly 

 summarized as follows : — 



1. Pajing results were obtained from the application of all of the mixtures. 



2. In no case was the foliage injured. 



3. The unwashed solution (a modification of eau-celeste) gave the. best results, 

 and the same preparation in suspension the lowest i-eturns. 



4. The addition of Paris green to the fungicides at the time of the second appli- 

 cation had no injurious effect upon the foliage, and increased the c^uantity of sound 

 fruit 8-2 per cent.
