As soon as the mildew made its appearance last year on our vines 

 they were thoroughtly sprayed with the above mixture. Two 

 applications and the removal of all diseased berries had the effect of 

 ■checking the spread of the malady, but at the same time demon- 

 strated — when compared with the results of my former experiments 

 — that the proper line of treatment leading to complete success, 

 lies in the early apjylication of the remedy. 



The following is the course of treatment planned for the vineyard 

 of the Experimental Farm this season : 



1. All prunings, leaves, etc., to be carfully bui-ned. 



2. When vines are uncovered spray them — including the posts 

 nhd trellises — with a simple solution of copper sulphate (blue 

 vitriol) 1 lb, dissolved in 15 gallons of water. 



3. Spray with the ammoniacal copper carbonate using the formula 

 already given soon after the fruits sets ; make two or three additional 

 applications at intervals of ten days or two weeks as the necessities 

 of the case seem to demand, 



4. Eemove and destroy diseased parts of the fruit and foliage. 



GOOSEBERRY MILDEW. 



The great di-aw back to the successful cultivation of the European 

 goosebery in Canada has been the annual loss occasioned by the 

 prevalence of this disease (Sphcerotheca mors-uvae B. & C.) The 

 external appearance of the fungus is well known, showing on the 

 young woods, leaves and fruit as a whitish downy coating, usually 

 appearing soon after the leaves have fully expanded. 



TREATxMENT. 



Successful results are reported by Prof, Groff of the Agi-icultural 

 Experiment Station of Wisconsin, by the use of Potassium Sulphide 

 (liver of sulphur) at the rate of 1 ounce dissolved in four gallons 

 of water. Spraying was commenced when the leaves were partly 

 expanded, and repeated seven or eight times during the summer. 



Without actual experiment it would not be wise to recommand 

 the unrestricted use of any remedy for this disease, but from our 

 present knowledge of the general efficacy of the ammoniacal copper 

 carbonate, it seems safe to advise a trial at any rate, of this remedy 

 in the same proportions as thofee given for the apple and grape.
