ELEVENTH ANNUAL MEETING. 27 



a commercial scale. ]\[r. Plant reports the black rot prevalent 

 even where the vines were sprayed, and suggests washing the 

 vines in the spring with a solution of copper sulphate in addi- 

 tion to regular spraying. Usually a thorough use of Bordeaux 

 will control it, supplemented in bad seasons with the weak 

 solution of copper sulphate, — three ounces to fifty gallons of 

 water. 



Anthracnose and mildew are controlled by the same appli- 

 cation. 



Anthracnose is reported as prevalent on the black rasp- 

 berry, but less on the red variety. Keeping the young canes 

 covered with Bordeaux, and cutting out the old canes as soon 

 as done fruiting, is the best treatment. 



Blackberry rust is reported in some sections. Cutting out 

 the diseased plants as soon as they appear is the only remedy, 

 Selection of resistant varieties is a great help. 



Leaf-blight of currants and gooseberries has been prevalent 

 in mv vicinity for several years, but I find little difficulty in 

 controlling it with two early sprayings with Bordeaux, and 

 one after the fruit is gathered. It may be out of my province 

 to remark here that I have usually included paris green in 

 the second application, but this year I used Bowker's Disparne 

 (which is but another name for arsenate of lead) with deadly 

 effect on the currant worms, and no deaths reported from 

 families using the fruit. 



The mildew of the gooseberry is a disease where selection 

 of variety counts for much, the American variety being little 

 troubled while the European kinds are very susceptible. 

 Potassium sulphide, one ounce to two or three gallons of water, 

 is the best treatment, though Bordeaux is useful in holding it 

 in check. 



The mildew of the melon can be controlled by Bordeaux, 

 but I have been unable to get any definite results in the treat- 

 ment of the blight, and I trust some light may be thrown 

 upon this most destructive disease during this meeting. 

 Unless we get help we must give up growing the muskmelon. 



In many sections the strawberry rust has caused great 

 damage to crops. The new beds must be kept sprayed, and 

 it is undoubtedly good economy to dip the young plants in 

 Bordeaux before planting. It will do little good to spray old 

 beds, or anv bed where the rust is well established.
