NINTH ANNUAL MEETING. 



DISCUSSION OF THE QUESTION LIST. 



Question : What is Peach Leaf Curl and how can it be 

 prevented? 



Answer — Professor Britton: It is a fungus. Spraying 

 will prevent it, only we do not seem to be successful in 

 spraying peach trees here in Connecticut. 



President Hale: In Michigan they spray their trees 

 when in a dormant condition, either with Copper Sulphate 

 or Bordeaux. 



Mr. Merriraan : Does the leaf curl amount to much 

 here in Connecticut? 



President Hale: I think not. I know of very few 

 instances. The Elberta peach tree makes a magnificent 

 growth of foliage in Michigan, but is so subject to the leaf 

 curl that they will have to abandon its growth. 



Q. Should fruit growers specialize or aim to produce 

 both the orchard and small fruits? 



A. Mr. Piatt: I think it will be wiser for them when 

 opportunity offers to specialize and raise larger quantity 

 and better, but we cannot always do it, but it should be the 

 aim of Connecticut people generally. 



Q. Is the twenty-five per cent mixture of kerosene 

 and water sufficient to kill the San Jose scale in all cases, 

 where properly applied? 



A. Professor GuUey: Not in all cases. I question 

 whether any spray of kerosene and water, or kerosene in 

 any form, will kill the San Jose scale so that it will not 

 appear again. Professor Johnson had sprayed trees as thor- 

 oughly as he could with a twenty-five per cent solution, and 

 there was not a live scale left that he could find, yet after 

 about a month there was plenty of live scale on the plants. 

 It cannot be relied upon to exterminate the scale. Spray- 

 ing, with crude petroleum is better than spraying with 

 kerosene.
