another, the more likely are you to have less of it the ensuing 

 season. But as I said before, the weather is practically the 

 determining factor as to whether brown rot shall be light or 

 heavy, local or widespread. Perhaps you will understand my 

 policy better if I state the proportions of varieties, or classes, 

 of peaches, that we grow. About 30 % of our trees are El- 

 berta. Elberta in many sections is very subject to brown 

 rot— that is, if brown rot is bad in a section, it will probably 

 do a lot of damage to an Elberta crop. On the other hand, 

 if brown rot is not extensively prevalent, Elberta may not 

 need protection from it. Now my theory is that if I can hold 

 brown rot down close enough on the white varieties compris- 

 ing the other 70 % of our trees, — the white varieties being 

 more susceptible to brown rot than the yellow Elberta — I 

 may be spared the expense of protecting Elberta by dusting 

 or spraying for some years to come. 



MR. VAN METER : From the evidence we now have on 

 the subject, I should think a man shipping peaches to distant 

 points would certainly be justified in dusting before picking. 



MR. HACKETT : I do not think a final dusting applica- 

 tion, say about ten days before picking, would do any harm, 

 although it might not be absolutely necessary. 



The CHAIRMAN : Mi*. Barclay, I wonder if you can tell 

 us what is being done in New Jersey in the way of dusting? 



MR. BARCLAY: I really know nothing about dusting 

 on peaches personally, but I think some growers in the state 

 have tried it out and it is quite satisfactory on peaches, more 

 so than it is on apples. 



THE CHAIRMAN: Mr. Frost, have you had any ex- 

 perience with dusting, or heard of people in this state or 

 elsewhere that have had- experience in dusting? 



MR. FROST : No, but I am convinced that dusting is all 

 right on peach or apple trees. It must not be overlooked that 

 it is necessary to have two outfits. You must have an out- 

 fit for liquid spray for the dormant application. If an or- 

 chard is large enough to stand two outfits, I think it is a good 

 thing to get into the dusting.
