buds come out, but two years age we had severe injury from 

 spraying with lime-sulfur just as the blossoms bloomed, by 

 causing a stunting of the whole tree, and for six weeks the 

 tree practically stood still. Last year we tried oil on two 

 orchards, and did very well, but there are a good many pears 

 in that section, and the pear psylla came from those neighbor- 

 ing orchards and from the fence rows and rubbish that 

 might be around, and so we feel that we can lay a great deal 

 to the oil, though we have got to follow it up by some spray 

 mixture until the pear psylla is controlled in the whole sec- 

 tion. 



MR. HITTINGER: I wish you could have seen our trees 

 seven or eight years ago. One year we had a lot of the Bosc 

 pears, and there wasn't a leaf on the trees. I thought they 

 were going to die, but I gave them a good spraying with oil 

 the next year, and the trees started out new, and I had some 

 nice pears, good and bright. I had a few pears on some of 

 the trees that were a little rusty, but not from the pear 

 psylla. 



QUESTION: What kind of oil did you use? 



MR. HITTINGER: Arlington Oil. 



MR. CLARKE: What do you use for summer spraying, 

 for instance, for the codling moth? 



MR. HITTINGER: Only arsenate of lead for the eating 

 insects. ' We haven't used anything for that fungus or any- 

 thing of that kind. We are a little handicapped. We have 

 crops underneath and we can hardly get in there to spray. 



QUESTION: What strength did you use? 



MR. HITTINGER : I think it was 1 to 12. I have used 

 1 to 15, but when I put it onto the apples it was 1 to 10. I 

 think, and now I use 1 to 12. I was going to say, that if I 

 was going to plant a pear orchard agairt I would give them 

 about 22 or 25 feet, and I would plant the rows north and 

 .couth, as I said before. 



THE PRESIDENT: You mean the rows 22 feet apart? 



]MR. HITTINGER : The rows 22, and the trees about 8 

 feet apart in the rows. That is the way I planted peachea.
