all know the indications. The only thing that we think of doing is 

 to tear it out as soon as we see it. Don't drag it through the orchard 

 or take any chance whatever. Dig it out immediately and burn it 

 on the stump. 



More trouble to us than the yellows, is the "little peach." It is 

 worse than the yellows in that it is quicker. It will put a tree out 

 of commission a year sooner than the yellows will. The peach is 

 not only small but the seed is correspondingly small. The leaves 

 are stunted and also if you take the leaves between the eye and 

 the sun there is a spotted condition. We do the same with that as 

 with the yellows and in wet seasons we have most trouble to hold it 

 down. It gets a little ahead of us. Scientific men see no reason 

 why it should. We feel that it is our greatest menace, and if you 

 haven't got it you want to be on the lookout. 



We dig out the borers in the fall. If you get them out anytime 

 before the 20th of May you are all right. We don't use any 

 wash on trunks. We used to whitewash them but never saw that it 

 had any effect at all. We take the dirt away to prevent the ravages 

 of the mice. They seem to have a regular home in there, and do us 

 a lot of damage. 



We have no trouble in holding the scale in check on the peach 

 by spraying with the sulphur and lime. We feel this has a three- 

 fold function: takes care of the scale and leaf-curl and has proven 

 a safeguard to a considerable extent against summer rot. Since 

 we have taken that up, we have never been bothered with leaf-curl. 

 As I said in the beginning, we have not done as much work on 

 summer spraying for fungous troubles as you have through here. 

 This fall I was over at Mr. Wertz' in the Cumberland Valley, and 

 he had used sulphur and lime somewhat through the summer, also 

 Bordoaux mixture, but his results seemed indefinite. 



ME. W. E. GROVE: How much lime and Bordeaux for peach? 

 MR. BARTON: 2-10-50. 



MR. BETERS: Is it possible that you get too much lime? 

 MR. BARTON : There is a point there. I don't think with 2-10-50 

 we would. 

 MR. PETERS: I used 2-4-50 with good results. 

 MR. BARTON: Our fertilizing is taken care of through the truck 

 crops in the early life of the orchard. After an orchard begins to 

 bear, we use a half-ton of muriate of potash and phosphoric acid 

 per acre and that, in addition to the green mulch, gives us as 

 rank an orchard as we can take care of. We have used crimson 

 clover to the extent of getting in a very dangerous condition and 

 this year we shall use no more than one-half the above application 

 of fertilizer, unless it is a little nitrate of soda as a medicine where 

 there is a sick-trer>. A Tier the fruit is thoroughly set in the spring, 

 we would use about 100 pounds to the acre of nitrate of soda on an 

 orchard which has cropped heavily the year before. But in a gen- 

 eral way, I would caution against any heavy application of nitrate. 



You do not make as great a growth up here in your hills as we 

 do in our sandy soil and you can stand a little more Bordeaux, a 

 little more copper sulphate, than we can because your foliage is a 

 little harder. We don't get as hard foliage and we expect to cut a 

 little of that foliage out with the Bordeaux, but we are glad to get 

 rid of it for the sake of getting a little more air. Remember that
