What can be done to prevent pear blight or tomato rotV 



rrof. Troop: That is something the United States department has 

 buLU worliiug on tor years. 



Mr. Van Deman: There is nothing that will destroy pear blight. All 

 you can do is to try to destroy the source of the disease. 



Prof. Troop: You should be very careful in cutting off pear blight 

 wood, so as not to inoculate the other parts of the tree if you use the 

 same knife again. It becomes a difhcult matter to stop pear blight when 

 it once gets started. Some varieties are affected more and some less. 



Mr. Van Deman: In the apple it usually doesn't affect a shoot more 

 than a foot. 



Prof. Troop: No, not more than that. 



Mr. Grossman: My Yellow Transparents are blighted so that I fear 

 they will die. 



Prof. Troop: That depends on the locality. I have had so many tell 

 me that they are having serious times with their Yellow Transparent, 

 and I have some right in among the other trees that ai-e blighted, and 

 the Transparents do not have a bit of blight on them. 



Mr. Grossman: I would like to know whether there is any difference 

 in the blight between the orchards that uvo cultivated and the ones that 

 are sprayed? 



Prof. Troop: Someone that has tried that can answer that question. 

 There is a great deal of difference in the varieties that blight, and our 

 orchards are made up of two or three trees of a kind. Some orchards 

 are cultivated and some have been soAved down in grass for years. I be- 

 lieve that those that have been cultivated all the time have blighted worse 

 this year than others. 



Mr. Grossman: That has been my observation. I have noticed that 

 the crabs have blighted seriously this year, .iiul instead of stopping it 

 is getting worse and worse. 



Mr. Flick: Some recent investigations Ijy the Commission appointed 

 by the State of California has recommended certain tilings with regard 

 to blight. First, tliat manuring pear trees should be avoided; second, 

 that the trees should be starved partially. 



Pi'of. Latta: I think witli a few announcements we might close. 



Mr. Peebles: I move you that we give a vote of thanks to the people 

 of this church for their kindness to us while we have been here, in the 

 use of the church and the furnishing of the special music we have had.
