" strawberry-root borer." It has attacked our peaches. He lays his 

 egg in the cross of the tree. If you spray early with lime, sulphur, and 

 salt you don't catch him; but if you will wait until just after he has 

 come out you never fail to kill him, and you kill everything pertaining 

 to curl leaf. You kill this scale and you kill the curl leaf. 



Mr. Dodson, of Shasta: I have had some experience with this dip 

 mentioned, both on prune trees and on Bartlett pear trees. My experi- 

 ence is that it not only kills the scale, but it seems to act as a fertilizer 

 to the tree. The past season I sprayed prunes early in the spring. 

 Those which I sprayed produced more and larger fruit than the trees 

 which were not sprayed, and it almost entirely eradicated the scale. 

 Late in the spring I sprayed the orchard of a neighbor of mine when 

 the pears were as large perhaps as three peas. There was a question in 

 the community as to whether or not the dip would injure the fruit, and 

 I examined the fruit after it got as big as a quail's egg, and I could see 

 the spray in the blossom end of the fruit, and it showed that it had not 

 injured it in any way, shape, or form, and that orchard is nearly clear 

 of scale. 



Mr. Block: I will give my reasons why I advocate early spraying 

 for the Lecanium that attacks the apricots and in many cases the prunes. 

 I used sheep-dip early in December on my trees, and destroyed the 

 scale effectually at that time. I believe in staying by what we have 

 found to be beneficial. I don't like to be making so many experiments. 

 And I know that it has a good effect if applied early. I don't want to 

 be experimenting in April or May to know what effect it will have then. 

 Now, in regard to the effect on curl leaf. The early wash has quite as 

 much effect on curl leaf as the late wash. In reference to the borer, I 

 know nothing about it. For that purpose it may no doubt be better to 

 spray later. No doubt rhy friend Motheral has had valuable experience 

 on that point. But with that exception I should recommend the early 

 wash. 



Prof. Hussmann: I would like to ask Mr. Block if that wash which 

 he uses has any effect on the codlin moth? 



Mr. Block: I should say not; I don't know. I have never depended 

 on it for the codlin moth. I depend on Paris green for the codlin moth. 



Question, " What is to be done when the individual's orchard is affected 

 by San Jose scale, and he is too poor to treat it?" 



Mr. Block: I would answer that he should become rich, and treat it 

 by all means. [Laughter.] 



Question, " What is to be done when a community is too poor to properly 

 treat the ravages of the San Jose scale?" 



Mr. Block: The community should move. [Laughter.] 



Question, " What course should be pursued when a man is able but 

 unwilling to treat San Jose scale?" 



Mr. Block: He should be made to get out of the community. 

 [Laughter.] 



Question, 11 In sections where the San Jose scale is prevalent, what pro- 

 tection should be taken by those whose orchards are free from it?" 

 Mr. Block: Spray.
