FORTY-FIRST ANNUAL REPORT. 117 



results with only one spraying, they used the arsenate of lead without 

 any fungicide with it. 



As I said before, there may come years when because of the atmos- 

 pheric or some other conditions, the lime-sulphur will not give as satis- 

 factory results as we Avould desire, but unless there is a change of a 

 material nature, or until something is found that is better, I think it 

 will be safe for us to go ou using lime-sulphur as a summer spray as a 

 substitute for Bordeaux mixture. 



DISCUSSION. 



A Member — Did you notice any fungus leaf-spot on cherries? 



Mr. Farrand — I cannot say for certain, although I think they must 

 have been about normal or I would have noticed it. I remember as we 

 were putting in our cover crop that I noticed a pretty good foliage. 

 If there had been any defoliation of those trees I would have noticed it. 



A Member ( further) ^Some cherry trees would have the cherries 

 hanging on with only a few leaves on the trees; on other trees the foli- 

 age was very good after spraying. I noticed these two conditions. 



Mr. Eose — Regarding the burning of certain varieties, would say that 

 we tested it thoroughly at our place, and found that the Wagoner, the 

 Grimes Golden and the 20-ounce Pippin were very susceptible to the 

 burning when Bordeaux mixture was used. Personally, I would not 

 recommend Bordeaux for spraying apples at all. There are some vari- 

 eties, like the Spy, for instance, that have a tough skin and will stand 

 it pretty well, but the great majority will not. The lime-sulphur solu- 

 tion did not affect them this way. 



A Member — Can we take care of cherries, without Bordeaux, using 

 lime-sulphur? 



A Member — I had some experience with plums — sprayed with 1-35 and 

 secured a good crop. On some others I tried 1-40 and I had rot. 



Mr. White — During this past year we performed some experiments 

 with commercial Bordeaux and self-boiled lime sulphur. On the plums 

 the commercial lime sulphur controlled the rot absolutely. On the 

 unsprayed trees the rot was so bad that the crop was not worth harvest- 

 ing. There was some rot where the Bordeaux was used. On sweet 

 cherries we tried the self-boiled lime-sulphur, 8-50, commercial lime- 

 sulphur, 1-40, on Windsors and one or two other varieties, the result 

 was that with commercial lime sulphur spraying there was a heavy foli- 

 age, but when we had that hot weather in July, 3-5, the sun did not 

 bake the cherries as in the others. On the unsprayed trees, and those 

 on which were used the self-boiled lime sulphur, the crop was so badly 

 withered up by the hot sun because of the lack of foliage, that the crop 

 was all lost. 



Mr. Rose — ^How did it come that you did not have any foliage? 



Mr. ^\Tiite — It came from shot hole fungus. We used commercial 

 lime sulphur and also Bordeaux, equally one with the other. Apparently 

 from our experiments which we conducted in an orchard a mile and a 

 half from where the United States Government were at work, we did our 

 work just at the right time, for on account of having to wait for direc- 

 tions from Washington they delayed for a week or ten days later than
