152 NEBRASKA STATE HORTICri/nRAI. SOCIETY 



Mr. Green : I do not want to enter into too many of these discussions 

 but just one point Mr. Duncan brought out, that I would like to emphasize 

 here. He spoke of diluting lime sulphur. Every fruit grower should have 

 his hydrometer and test his solution before he uses it and go according 

 to the hydrometer test. I believe that he will find that if he will spray 

 for scab before he does his rluster bud spraying he \\ill find less scab. 



A Member: I would like to inquire about how many acres growers 

 find it possible to handle with one spraying outfit. We had one machine 

 and had about twenty acres in our home orchard, and could get over that 

 just about right, and then we had ten acres in our other orchard, and by 

 the time we got over that, we were a little too late and wonder if the 

 machine was not large enough, or if we were too slow. Of course these 

 trees were good sized, and about 25 years old. 



Mr. Marshall: We have an orchard of about 1,000 trees that we have 

 been spraying. We have to haul the water just a few rods. We dip it 

 from a tank usually into the sprayer and we can put on from seven to ten 

 loads a day, and it takes us about two or three days to spray this orchard. 

 Sometimes we get over it a little quicker, but the second spraying we put 

 in three good full days to spray them. Now maybe we are a little slow, 

 but these trees are about twenty years old, and just ordinary sized trees. 



Q. How large is your tank? 



A. Two hundred-gallon tank. 



Q. How many leads of hose do you use? 



A. Three. 



A Member: I would like to say that in our experience in this line, 

 we have three different sized sprayers, and we are using 250, 200 and 150- 

 gallon tanks. We figure we can get out five tanks a day of the 250-gallon 

 size. We figure that the tank will cover, depending on the size of the 

 trees, on an average, twenty to thirty trees to a 250-gallon tank. And we 

 can get five or six tanks a day out. We, of course, are a little fortunate 

 in having our water right in our orchard. We have a forty acre orchard 

 in this particular instance. That has been our experience in the amount 

 we can cover, and I should say one sprayer in every forty acres is a great 

 plenty. You would not want m ire than forty acres to one sprayer to do 

 any kind of a good job, and in fact thirty acres would be better for one 

 sprayer. 



Q. Do you think that a man can cover tliirty acres in proper time? 



A. Yes, sir, I think so. 



A Member: It seems to me that if you can get over with one ma- 

 chine in proper time, it depends on what you are spraying for. When it 

 comes to the first codling moth spraying, that is a hurry-up job. Your 

 calyxes stay open just a day or so, and then you must spray while the 

 calyxes are open. It seems to me that the number of acres that you can 

 assume that that spraying machine can cover, any specific number of 

 acres, depends largely on what you are spraying for, and the varieties. 



Mr. Yager: All of the talks so far this morning, have been relative 

 to commercial orchards. Now there are thousands of farmers in the state
