we did, aud the result was they lost their foliage very badly. This was 

 all due to the few days' delay. 



Prof. Green — We have come to the conclusion that the lime-sulphur 

 is not so strong a fungicide as Bordeaux, and does not control grape 

 rot and bitter rot so well. Lime-sulphur is strong enough for most 

 l)urposes. On the other hand, Bordeaux sometimes does a lot of damage 

 to the apple and the foliage. What we call the "Yellow Leafing" or 

 yellowing of the leaf in June, turning yellow and falling off in some 

 varieties, especially the Rome Beauty. Bordeaux makes it worse. Some 

 of our experiments that we laid out where lime-sulphur and Bordeaux 

 had been used the year before, we found that the results of that year 

 had been such that the value of our experiment was destroyed. That is, 

 the Bordeaux did so much harm that the leaves all fell off and there were 

 no fruit buds this year. This has occurred with us several times in the 

 past, and so we have come to regard Bordeaux as rather risky to use 

 because of this result, as well as from the russeting of the fruit. 



Mr. Farrand — For the past ten years, with all the work I have put in 

 along this line, I have been conservative. I would be the last one to 

 let the bars down by throwing away something that shows good results 

 without first giving it a thorough trial. Twenty years ago we did not 

 have the injury from the Bordeaux that we have now — I can not explain 

 why^ — it has been the greatest spray for apples we have ever had in 

 Michigan, and yet during the past two to four years there has been a 

 good deal of injury resulted from the use of Bordeaux. And yet I am 

 free to say that I would rather have that injury than take the chance of 

 not using any spray. But with the experience I have had I would 

 not spend a cent for blue vitriol as an apple spray, and if anyone would 

 ask me for my opinion I Avould advise that they use lime-sulphur instead 

 of Bordeaux aud honestly too. What the future will bring forth I do 

 not know. I may change my mind — that will depend on new facts that 

 may possibly be brought to light on this subject. 



A Member — Do you not think that 1-50 spray for the summer would 

 be strong enough? 



Mr. Farrand — I do not know — I use 1-35. 



A Member — We use 1-50 on all orchards in our locality, and it seems 

 to be strong enough. 



Mr. Farrand — I am glad to know this, but as for myself I do not want 

 to take any chances with the scab. 



A Member — How late do you consider it safe to spray, providing you 

 could not get jonv spraying done earlier — at the opening of the leaf or 

 buds? 



Mr. Farrand — We had an orchard that we sprayed with a solution 

 1-8 when the foliage was out, little leaves had started, and the buds 

 were swelling and some of the blossoms had opened, and we think it 

 was the wisest thing we could have done. We had some little injury 

 to the foliage, but it was a wise thing to do. 



Prof. Green — We had a case of that kind, and it killed nine-tenths 

 of the blossoms. I had done it in previous j^ears without serious injury, 

 but I do not think it is very safe to spray as late as that. 



A Member — I would like to have answers to question No. 34, which 

 is, "Does Lime Sulphur deteriorate by freezing?"
