68 NEBRASKA STATE HORTICULTURAL SOCIETY. 



Mr. Beltzek: Talk about these cedar trees. I don't believe 

 in cutting them down; in same parts of the state I imagine the 

 cedar trees are as valuable as the apple trees. I w^ant to say 

 that on Platte Valley there vv^as a lady experimenting wath this 

 cedar rust, and she commenced to use w^ood ashes v^hen the 

 dew was on, or just after a rain, and that tree looked a hundred 

 per cent better. There was a cedar ball there, and I examined 

 it, and it seemed dead. My opinion is that the spraying did 

 some good. There are trees twenty years old in our county 

 that haven't died. 



Prof. Emerson: In the lasttwo years there has been abhght. 

 I don't think it is business for horticulturists to study the 

 fungus diseases; I think that is the business of the botanists. I 

 think it is their duty to try to control these diseases. I cannot 

 study these diseases as botanists do, I haven't had the training 

 in this line. 



Mr. J. R. Davidson: Will spraying do much good if followed 

 immediately by heavy rains? How do you manage to keep the 

 spray on the tree? 



Prof. Emerson: I admit when you have a large orchard 

 and have to get in there with heavy machinery, it is a hard 

 proposition. There has not been a single time this year w^hen 

 it has not rained within forty-eight hours, and most of the time 

 the night following. In one case I began one afternoon and 

 sprayed for two or three hours, and was compelled to quit on 

 account of heavy rain, and the trees which were sprayed in the 

 first part of the afternoon the next day looked just as well as if 

 the rain had not come at all. The trees sprayed immediately 

 before the rain didn't show much of it. I don't believe after it 

 is dry once it will wash off of apple trees. If you can get into 

 the orchard, I will risk the rain washing the spraying off. I 

 would not stop for that. 



Mr. Russell: If they are through with this question of 

 cedar rust and spraying, I would like to ask the Professor if he 

 has had any experience in spraying the peach tree for this 

 blistered leaf? 



Prof. Emerson: I have not had any experience except I 

 have sprayed two or three trees and see no disease this year.
