will lose every leaf, so it jsn't safe for the grower to go 

 ahead blindly. If youwant to experiment and try, that is 

 a different matter. 



MR. TENNEY OF MAINE. I would like to ask, if you 

 use the same strength of spraying material at the first of 

 August, if there wouldn't be danger of your hurting the 

 fruit? 



DR. WHETZEL. You want to know whether the same 

 strength of solution should be used for all the sprayings for 

 scabs ? Yes : one to forty. There is less danger of burning 

 your foliage in the first spray than there is the second and 

 third. As I pointed out, when the leaves first come out the 

 surfaces are protected by a cuticle which is perfect. Yoa 

 can actually use a stronger solution. As a matter of fact, 

 I know men in the State of New York who have used one to 

 eleven for this first spray when the blossoms showed pink, 

 without any injury. However, I shouldn 't advise you to try 

 it. On the other hand, with one to forty, if the foliage is 

 injured you will get serious burning. The general practice 

 is, however, one to forty. If you are to dilute it any it 

 should be later, the first of July or August, and then per- 

 haps one to fifty would be safer, because the foliage is cer- 

 tain to be more or less injured then and you might get more 

 or less injury by burning. I have never seen any cases 

 where it caused injury to fruit under ordinary circumstan- 

 ces. I have seen cases where they thought it did, but when 

 an examination was made the evidence didn't bear that out. 

 Apples may scald in hot weather from spraying with any- 

 thing, but that is due to the water, and the action of the 

 sun. 



MR. WILDER OF LANCASTER. Will the Professor 

 kindly tell us the spraying outfit he uses for his small or- 

 chard? 



DR. WHETZEL. I use the Gould Pomona outfit. A 

 barrel hung in a cart, and I can carry 200 pounds pressure 

 with that pump. Of course, I have to work a little, but they 

 say that exercise is good once in a while for a professor. I
