United States Department of Agriculture — Instructions for Sterilization of Sand, 



Soll or Barth Used for Packing Bulbs Imported Under 



Notice of Quarantine No. 37 



Amendment No. 1 to the regulation supplemental to Notice of Quarantine No. 

 37, provides that the requirement of regulation 3 as to freedom from sand, soll 

 or earth of nursery stock and other plants and seeds permitted entry under that 

 regulation, shall not apply to sand, soll or earth used for packing the articles 

 enumerated in item No. 1, when such sand, soll or earth has been previously 

 sterilized in accordance with methods prescribed by the Federal Horticultural 

 Board under the supervision of a duly authorized inspector of the country of 

 origin. 



The requirement as to sterilization may he met by heating the sand, soll or 

 earth to a temperature of 100 degrees Centigrade (212 degrees Fahrenheit) and 

 maintaining that temperature for a period of one hour. Such sterilization is 

 accomplished at one of the field stations of this department by the use of a large 

 iron receptacle holding about a cubic yard of soll. A fire is built under the 

 receptacle and in a Short period the contained earth is heated sufficiently to kill 

 all larvae, nematodes, etc. It is necessary to keep the soll stirred while heating. 

 Any device which will maintain the heat at the required temperature for one hour 

 will be satisfactory to the board. 



The invoice covering importations of bulbs packed in such sterilized sand, soll 

 er earth must be accompanied by a certificate of a duly authorized inspector of 

 the country of origin to the effect that the required sterilization has been accom- 

 plished under his direction. The certificate should indicate the marks and 

 numbers on the cases and should contain such other Information as may be 

 necessary to identify the cases which it Covers.
