TWENTIETH ANNUAL MEETING. 03 



with the question box, there was what was to me a very 

 interesting" vote on a particular question that was asked by 

 the man in charge of the question box, as to how many 

 were going to use lime-sulphur during the season of 1911 

 as a spray mixture for summer spraying of their apple 

 orchards. I suppose there were a thousand people in the 

 room, and it looked to me as though all of them got up. 

 After they sat down he asked how many^ were going to 

 use Bordeaux mixture. Not a single man got up. Now 

 that is significant, because two years before had that same 

 question been asked, the vote would certainly have been 

 practically the other way. It seems to me it is remark- 

 able, that within a space of two years in the State of New 

 York, so conservative a bunch of growers as we have, men 

 inclined to go into a new proposition carefully and slowly, 

 should have absolutely changed from one fungicide to 

 another. It must be due to the fact that that fungicide is 

 eminently successful and readily used by the average 

 grower with success, or else we could hardly have expect- 

 ed so marked a change in so short a time. 



Of course, the main objection which has always been 

 urged against Bordeaux mixture, and urged more strongly 

 as we have come to use it more extensively, is the objec- 

 tion, not that it does not control apple scab, because, as 

 Doctor Clinton has pointed out to you in his paper, 

 Bordeaux mixture controls apple scab about as well as 

 does lime-sulphur. It has been very successfully used as 

 far as scab is concerned. But it does, in some seasons, and 

 under certain weather conditions, cause russeting and scab 

 of the fruit. When it is not scab it is russet, and scab 

 and russet do not please the man who buys fine fruit. 



Then, of course, there has always been the objection to 

 Bordeaux mixture in wet seasons also, that more or less 

 leaf injury occurs. Now whenever the operator is ready 

 I will be glad to have him throw some pictures on the 

 screen and try to follow those pictures in telling you some- 

 thing of the work we have been trying to do at Cornell
