REPORT OF THE SOCIETY , 35 



the experimenter does not dust so early in the morning as the average 

 grower. 



Last year I came upon a new type of data. Oneof the bankers in William- 

 son, N. Y., decided that he would find oat how dusting really worked out. He 

 sent a man to every grower shipping apples into Williamson and got the full 

 data on material used, average crop and pack out of the fruit. 



Pack out of all apples shipped through Williamson, N. Y., Season of 1921-22. 



This is rough data and some of the sprayed orchards gave excellent 

 fruit and some of the dusted ones poor fruit, but there are some things here 

 that cause us to wonder. We find here that the growers are not getting the 

 same relative results from spraying and dusting as the professional experimen- 

 ters are get ting. Apparently the farmer is not doing his spraying as thoroughly 

 as the experimenter and he is doing his dusting a little better. These differences 

 in results make us wonder whethter we would serve the country better by 

 advocating dusting or by advocating spraying. 



Some of you may say^ "That is the opinion of a dust enthusiast who is 

 now manufacturing dusting material". That is true, bii'^t let me tell you 

 that for immediate profit there is more money to be made is Paris grfeen, 

 a material that we manufacture and do not recommend, than in all the dust 

 that has ever been made. We have to manufacture what the public demand. 

 In such a gathering as this I try to recommend what I think is best irrespective 

 of the profit that may be in it. 



The question of dusting vs. spraying is one that the farmer has been forced 

 to settle and is settling to his own satisfaction since experimental data is not 

 proving to him an accurate guide as to what he can accomplish in his own 

 way in his own orchard. 



I think that I am safe in saj'ing that 95 per cent of the experiment station 

 workers refuse to recommend dusting yet. I know of numerous questionaires 

 that have been sent out to orchardists who are dusting and invariably over 

 95 per cent of the users have expressed themselves as satisfied with the method. 

 On a recent qUestionaire sent out in the United States 97 per cent of the 

 owners of dusters stated that they intended continuing dusting. There is
