174 Twenty-Second Annual Repokt of the 



The Commissioner of Agriculture exempts from fumigation all herbaceous 

 plants, conifers, greenhouse plants, flowers and cuttings, but this does not 

 refer to stock that may distribute injurious pests or disease. Certificates 

 issued by this department will be valid until September 1, 1916. No certi- 

 ficate will be granted on a final inspection made earlier than August 1, 1915, 

 and the most important inspection work will be done after August 1 and con- 

 tinue throughout the year wherever it is found necessary. 



Vineyardists who make a business of selling cuttings, and small fruit 

 growers who do no general nursery business will receive a special certificate 

 of inspection. Transportation companies class cuttings as nursery stock and 

 require copies of inspection certificates. 



Duplicate certificates of inspection will be furnished by the department for 

 filing in the offices of the states requiring them, as follows: 



Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, 

 Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, North Caro- 

 lina, North Dakota, Rhode Island, South Carolina, Tennessee, Texas, Virginia, 

 Wisconsin and Wyoming. 



To avoid delay and possible loss of stock, no nurseryman should ship to 

 another state, without first having learned the requirements of that state. 



SCALE-MARKED TREES SHOULD NOT BE SHIPPED 



If trees infested with San Jose scale have been treated in an approved 

 manner, and at a time long enough prior to inspection to be convincing that 

 no live insects are visible, shipments may be permitted, but not otherwise. 



Nurserymen are advised that it is not regarded good policy to use scale- 

 marked trees. 



The following letters were received in June, 1915, from the inspection 

 authorities of five of the largest nursery stock-producing states: 



With reference to your inquiry as to our attitude concerning the presence of San 

 Jose scale on nursery stock which has been sprayed and then followed by fumiga- 

 tion, I would state that it is, of course, preferable that stock should have no 

 evidence of scale in any condition. I realize the difficulties in the way of this in 

 some cases, however, and for some little time we have been guided, in the acceptance 

 or rejection of stock, by our own findings. "Where we find living scale, whether 

 the trees have been treated or not, we either reject the stock or require its treat- 

 ment at the consignor's expense. 



However, if any person finding scale on the stock, either living or dead, should 

 object to receiving it on that account, I believe we should support him in his posi- 

 tion and feel that, as he is paying for the stock, his wishes in the matter should 

 be considered. 



Regarding your inquiry as to the attitude of nurserymen shipping nursery stock 

 which shows marks of scale, I advise our men against such practice, on the basis 

 that dead scale or scale marks hurt them with the growers as badly as if the trees 

 were infested with live scale. 



Our policy is that they should throw out any stock that has been infested with 

 scale, believing that by such policy we eliminate to the minimum any trees that 

 might slip through hand inspection. As a general rule, I believe our nurserymen 

 follow this practice, and, as we check up on their work by sending an inspector 

 to the large nurseries at given periods of the year during the shipping season, I 

 believe that they are following it as carefully as possible. That does not necessarily
