DISCUSSION 57 



about as clean an orchard as we found in the state this year. 



Now on our experiments in orchards at Bracken, the lime sul- 

 phur showed correspondingly less burn under the same conditions. 

 The same thing was tL^ue at Florence, where we had a great deal 

 of rain during the season, that is compared to the rest of the state, 

 the bordeaux mixture continued to give us more burns there than 

 the lime sulphur, and of course the lime sulphur correspondingly less 

 burn. 



A Member: I was ten years in the Grand River Valley In Col- 

 orado, and there they use banded trees, and sprayed twice with the 

 best results. And some sprayed with good results, where they have 

 been careful for years, with two sprays, and have about 85 to 90 per 

 cent. I would like to know if there is any man in Nebraska who has 

 banded his trees, and got the moth from a band? 



A. I don't know of anybody. I always banded a few of the 

 trees when I found that the coddling moth was coming on. I found 

 ic was a good proposition. 



A Member: I have been through Washington, Oregon, Cali- 

 fornia, Idaho and all the valleys, and I have had experience in all of 

 them, and I am willing to come back and take my chances in Nebraska. 

 This year my apples,^ — if I wantel Jonathans, they cost me $6.50 a 

 barrel up at Kearney, raised down in the eastern part of the state 

 here. You fellows didn't get any such big price as that. Did you? 

 And I would like to know the cause of it. I had to pay out in Col- 

 orado, $1.75 per box, and then paid the express of $1.75 more. 

 It is pretty hard to live in Nebraska without fruit. 



Mir. Pollard: There is a question I would like to ask in regard 

 to this spray burn. Did you make any observations as to whether or 

 not you had a little burn on all the trees as you went down the row 

 or whether they were in one or two trees together? 



A. Well this is a fact. We had some spray burn on all the 

 trees, but in certain places there were some trees that had more 

 spray burn than others. 



Q. (By a member): What do I understand you to mean, by 

 an open spray, simply an enlargement of the disc of the nozzle? 



A. I said the penetrating spray. Now in the penetrating spray 

 we use the nozzle that turns the spray in a fan shape and with a 

 great" deal of force, and there is not much missed. 



A Member: I wish you would review in brief and sum up all 

 these combinations, between the bordeaux, and this other spray? 



Professor Cooper: The bordeaux spray does not seem to injure 

 the Genitan and the Missouri Pippin apple, to any extent, but the 

 other varieties it burns a great deal more. So in order to control 

 this, I would say to spray with bordeaux mixture for the first spray.
