may make the matter more clear. A bag of dusting material 

 is placed in the hopper— about 100 qounds. The motor is 

 started with the dust outlet closed. The team enters the 

 row, and the outlet pipe, about four inches in diameter, is 

 opened. The man stands on a platform at the rear of the 

 wagon, and as the team moves along, he sweeps the outlet 

 pipe toward the tree, creating a big cloud of dust, that en- 

 ters the foliage, and rises above the tree, finally settling 

 down through the foliage. If it is properly done it must cov- 

 er everything. Then he turns to the other side of the row, 

 and sweeps the outlet pipe to cover the trees on that side, the 

 team moving along all the time, its speed guaged to the time 

 required for covering the trees on both sides, and the time 

 varying with the size of the trees. As to the protection from 

 brown rot developing in transit, I think that will depend 

 largelj^ on how the crop has been protected in the growing 

 stage and the weather the peaches are subject to in transit. 

 We all know how big a factor the weather is in encouraging 

 or retarding brown rot, all through the season. I do not at- 

 tempt to state it as a positive fact, but I think it is true tliat 

 peaches that have been protected by dust applications 

 through the growing season will stand up better in tranrdt. 

 Our own fruit last year stood up better than it ever did 

 when we used liquid summer spray. We have the statement 

 of one of the large growers in New York that the dusting 

 makes the fruit travel better to distant markets. If the dust 

 has been applied in the growing season so as to prevent the 

 development of brown rot, I would not think a special appli- 

 cation necessary just before picking in order to protect the 

 fruit in transit. 



MR. VAN METER: Do you think, one year with an- 

 other, you can always depend on controlling such a disease as 

 brown rot ? 



MR. ITACKETT: You mean eradicating the disease? 

 No, because I do not think brown rot can ever be wiped out. 

 What you can do is to hold it in control in your own or- 

 chards. The better you control In-own rot, one season with
