ently set free. In the State of New York I recall no cases 

 where injury of serious nature was due to that. 



There is one thing which I might mention, and that is 

 that you are practically certain to get serious injury from 

 lime-sulfur and arsenate of lead if you spray foliage that is 

 already injured. The common experience of our growers 

 is that in the early spraying there is a little burning; then 

 they use a much stronger solution when the leaves are young 

 than when they are older. The answer to that question is 

 that when the leaves become older they, get scabbed or 

 pimctured by insects, which allows the mixture to go in and 

 you get spots. Another reason why you should spray just 

 before the blossoms open is that if you get a bad infection 

 (•f scabby foliage and go on and spray after the blossoms 

 open, you will get bad burning and you will say it is bad 

 stuff. Well, it isn't. If the leaves are perfect and have no 

 .spots on them lime-sulfur, one to forty will not injure them. 

 MR. CARTER OF WILMINGTON. I would like to ask 

 the gentleman if it isn't necessary to use a different kind of 

 spray for peaches and plums and grapes than what we do 

 tor apples'? 



MR. WHETZEL. Yes, sir, you can use a lime-sulfur 

 for apples. Generally speaking, you cannot use lime-sulfur 

 i^olution for peaches or plums or grapes. It has a dwarfing 

 and burning effect on grapes, even in very dilute solution. 

 We have tried it out very thoroughly on grapes in New 

 York State. If I had peaches or plums in the orchard I 

 should use commercial lime-sulfur, that is, on my own or- 

 chard. I don't want you to try it, just because I would, be- 

 cause you might burn all j^our leaves off. But if I had a 

 peach or plum orchard I should use it from one to one hun- 

 dred and fifty to one to two hundred for the control of thr; 

 brown rot and scab. I use it right along on my plum trees 

 at home, five or six of them, and have never had any serious 

 trouble. They are a little spotted, but nothing serious. 

 Certain varieties of peaches can be sprayed with a stronger 

 solution, about one to fifty, and others right side of them
