make much difference whether it was Bordeaux or the self- 

 boiled or some other sort. 1 think that the rust, as I stated 

 in my paper, will depend on the number of sprayings. Ordi- 

 narily the two or three sprayings that are given in this state 

 will not control rust ; you will have to make at least three or 

 four with whatever fungicide you use. 



Vice-President Drew: You mean cedar apple fungus? 

 Dr. Clinton: Yes. Just a word about Bordeaux. 

 While I said I ■ preferred commercial lime-sulphur to Bor- 

 deaux on apples, I did not prefer it on potatoes and melons. 

 Bordeaux is the standard yet for potatoes and melons, in my 

 opinion. 



A Member : How about grapes ? 

 Dr. Clinton : I have not tried it on grapes at all. 

 Prof. Whetzel: Dr. Riddick has tried out the com- 

 mercial and the self-boiled in comparison with Bordeaux, and 

 all the evidence goes to show that Bordeaux is the only thing 

 we can use in the state of New York for black rot of grapes. 

 A dilution of lime-sulphur of 1-75 or 1-100 on most varieties 

 of grapes, we find, will cause serious burning, and in some 

 cases will cause a shriveling of the fruit. We cannot use 

 lime-sulphur as yet for grape spraying. 



I saw some interesting photographs from Virginia of 

 apples sprayed with a new type of lime-sulphur. It was not 

 concentrate, but some other type of lime-sulphur, some com- 

 mercial brand, which in the pictures looked very good, and the 

 man in whose orchard the apples were grown, was there 

 and swore they were all right, but I didn't see them. I have 

 no doubt but what the diseases can be controlled with sulphur 

 sprays of this type. 



Mr. Hillyer, of Farmington : It seems to me here is an 

 opportunity for a further word, although there is a commer- 

 cial element in what I have to say. Prof. Whetzel in his 

 speech has spoken of the effect of the self-boiled sulphur as 

 being probably due to the elementary sulphur which was used 

 in it. Other experiments seem to show that horticulturists
