NINTH ANNUAL MEETING. 23 



withstanding' the dryness of the past season, it attacked 

 vineyards with great severity. Mr. Plant reports that in 

 his own vineyard spraying completely prevented it. 



The Black Rot (Laestadia) is unquestionably the most 

 serious fungous disease of grapes in this State. During- 

 the last season there was much less of it than usual, proba- 

 bly owing to the dry weather, and vines which were 

 sprayed were entirely exempt. 



Melons. — The Wilt (Bacillus and Fusarium) was 

 extremely destructive everywhere. The trouble seems to 

 be steadily increasing throughout the State. Spraying 

 seems to have no effect upon it and as yet we have no cer- 

 tain means of checking it. 



The "Downy Mildew" (Plasm opara) occurred last sum- 

 mer for the first time to any extent. It proved a serious 

 trouble in a few localities. 



Should it increase there is every reason for supposing 

 that it may be as readily held in check by spraying as is 

 the Downy Mildew of the grape. 



TREE FRUITS. 



Pear. — Mr. Plant reports the usual quantity of Pear- 

 scab (Fusicladium) where trees are not sprayed. I do not 

 think any disease of the large fruits responds more satisfac- 

 torily to spraying than pear-scab. In this matter, Mr. 

 Plant speaks from wide experience. Mr. Plant has had 

 trees in his pear orchard for years that have been affected 

 with the Fire Blight (Bacillus), but, upon the whole, he 

 reports that this disease is not increasing throughout the 

 State. Although trees can be kept along for many years 

 by careful pruning, old trees affected with it will finally 

 succumb to it. 



Apples. — The apple was quite free from disease this last 

 year, owing largely to the climatic conditions, making it 

 one of the off years for fungous depredations. It is doubt- 

 ful if, under such conditions, spraying was a profitable 

 operation. 



Quince. — The Leaf Spot was quite prevalent. The 

 Quince seems to be a tree that it is impossible to get any
