THE REPORT OF THE 



No. 36 



received the Codling Moth spray, but not the one just before bloom, the Greenings 

 and Spys averaged from 35 to 30 per cent, scabby fruit, and the Gravenstein 50 per 

 cent, or upwards, while a heavily loaded Gravenstein in the dusted plot averaged 

 6 per cent, scab, but it should be mentioned that this tree, owing to its blooming 

 earlier than the other trees of the orchard, had been sprayed with lime-sulphur 

 three days before it was dusted. (The dust had not arrived yet). 



An examination of 'many trees throughout the district led us to estimate that 

 in general unsprayed Spy trees were about GO per cent, infested with Scab, Green- 

 ings and Baldwins about 40 per cent. These figures show that in spite of the wet 

 season, the scab fungus was not specially abundant in the Grimsby district, and 

 therefore much better results were obtained by spraying there than would likely 

 have been obtained in almost any other part of the Province. The average un- 

 sprayed orchard elsewhere would show 95 per cent, of scabby apples. 



Another view of the dusting machine at work. 



What has been said shows that dusting as done by me under Grimsby weather 

 conditions, gave satisfactory results on Apple Scab, but I fear I could not have 

 obtained nearly so good results in most, or perhaps, in any other part of the 

 Province. Mr. Kydd, of the Fruit Branch, Toronto, who is just as thorough an 

 experimenter as I am, did not secure nearly so good results from the dust spray as 

 from the lime-sulphur liquid spray. The contrast is a striking one.
