Bpray applied just as the leaf buds are beginning to swell would prove 

 very beneficial, not only in the control of any aphids or scale, which 

 may be present, but to some extent in preventing the spread of 

 Illinois cranker. Dormant spraying will not control this disease after 

 It has once gained entrance into a tree. But should aid in prevent- 

 ing Infection, through winter pruning, wounds and other injuries. 

 The dormant spray will at least prove a good insurance for young 

 orchards. 



Discussion. 



Mr. Pollard: I notice in the opening of this latter discus- 

 sion you state you made your first spray with bordeaux, and you fol- 

 lowed, — the next two with lime sulphur, and then followed with bor- 

 deaux and vice-versa, do yott have any place where you sprayed only with 

 lime sulphur? 



A. Yes sir, in every case we aimed to have one block in every 

 orchard sprayed with bordeaux mixture straight, and one with lime 

 sulphur straight, and then with diffrenet combinations of spraying. 

 That being the case of the orchard at Wymore, which gives better 

 results where we sprayed with lime sulphur than where we sprayed 

 with bordeaux mixture; we got as good results as we did with the 

 bordeaux, but the lime sulphur on account of the hot dry weatner, 

 seemed to cause very much more spray burning, and much more 

 deeper burn than the bordeaux did. Now I think that was found to 

 be the case in the Kansas experiments, a few years ago, that the 

 lime sulphur was inclined to burn a great deal more severely than the 

 bordeaux mixture. 



A Member: Wouldn't it be practical to dilute this lime sulphur 

 solution? 



A. YoU' might weaken the solution but the question is to get 

 the solution to a point where it will destroy all of this fungus disease 

 and at the same time not to injure the tree. 



Mr. Pollard: In answer to Mr. Williams' question, I think thai 

 in the orchards where they used lime sulpbur exclusively, where 

 they used less than a gallon and a half of lime sulphur to 50 gallons 

 of water, they didn't control the scab. 



Prof. Cooper: Did you have as much burn though? 



Mr. Pollard. We didn't care so much about the burn. It we 

 controlled the scab, that is all we wanted. And in my own orchard 

 at home, that I have charge of, we have practically no burn. We 

 used a gallon and a half with subsequent sprays in my orchard. 

 In the orchards where they used less than that, without a single ex- 

 ception, they did not control the scab. 



Prof. Cooper: I would like to say gentlemen that while I have 

 been through Mr. Pollard's orchard, several times, and while we 

 didn't make any experiments on his orchard he seemed to have
