THIRTY-SEVENTH ANNUAL [REPORT. 101 



Q. How much lime do you use? 



Mr. Farnsworth: We put in about four pounds. If lump lime, then 

 three pounds would be enough. With the hydrate of lime a little more is 

 required; it is a little more expensive than the fresh lump lime, but a little 

 more convenient. 



With regard to the spraying of the lime and sulphur upon trees up to the 

 blooming time: it is perfectly safe to spray with lime and sulphur on the 

 peach up to the time the blossoms open. I have tried it year after year. 

 It may burn the apple foliage slightly, because the leaves on the apple get 

 much farther advanced at the time of blossom than on the peach. This 

 question comes up. We find people that just find out the scale is in their 

 orchard possibly late in the season, and they say, "I. am afraid I will kill 

 my buds, or burn the foliage, and this will hurt my blossoms and possibly 

 the tree, and I don't want to spray." By all means spray for the San Jose- 

 scale, even if the leaves are out up to blossoming time, on any kind of fruit, 

 rather than let it go over for the season. Better do it a little earlier; but do 

 it anyway. 



Q. If you had an orchard and only once in a while a tree that had a scale 

 on, would you spray the 'whole orchard, or wait a year or two? 



Mr. Farnsworth: I would spray the whole thing right away, because 

 if you find it pretty generally on one or two trees, the probabilities are it is 

 scattered here and there all over the trees. Mr. William Miller said he 

 would spray all his trees with the lime and sulphur if he did not have a scale 

 on the place, it seemed to have such an invigorating effect, as well as fungicidal 

 effect. I only have a few scales here and there over the orchard, and I spray 

 every fruit tree except the sour cherries, because if I find here and there one, 

 there are many scattered over the orchard. As a matter of benefit to the 

 entire orchard, I spray them all. There might be exceptions to that. If 

 I had good reason to think in a large orchard there were only a few trees, 

 it might be better to spray that tree and a few surrounding trees. I rather 

 tell what I do than to give general advice. I simply say in my case I do 

 spray them all. 



Q. Ever see any scale on grape vines? 

 Mr. Farnsworth: No, I never have. 



A Member: I advise a little caution in using lime and sulphur during 

 the growing period of the trees, especially in the spring when the trees are 

 very sappy and the young foliage is coming out. I know from experience 

 it injures foliage; the leaves being the lungs of the tree, it would retard the 

 growth and have a tendency to check their growth; and I have been very 

 cautious in that respect. 



Mr. Farnsworth : Better to get it done before the foliage appears if possible. 

 Same Member: The insoluble oil will be more to be recommended 

 during that time of year, and in fact during the entire growing season. I 

 don't think the wrong impression ought to be brought out here with reference 

 to the sulphur and lime solution being used during the time when trees are 

 growing, because it is injurious to the foliage. 



Mr. Farnsworth : We never have used it after foliage is formed and would 

 consider it dangerous. 



Mr. Crane: That was my experience last year. Brother Taft was in 

 my orchard when 1 was spraying for the scale in the spring, and I put the 

 question to him how long I could spray, and he thought it would be safe 

 up to the time they bloomed. I wanted to know whether I could use that 

 spraying instead of the first spraying of the Bordeaux, and so I left a little
