PUBLIC HEARING CALLED TO CONSIDER THE ADVISABILITY OF QUARANTINING 
THE STATES OF CALIFORNIA, COLORADO, NEW MEXICO, TEXAS, AND UTAH ON 
ACCOUNT OF THE PEACH MOSAIC DISEASE 
[Press notice] 
August 21, 1936. 
A public hearing to consider the advisability of quarantining the States of 
California, Colorado, New Mexico, Texas, and Utah on account of the peach 
mosaic disease will be held before the Bureau of Entomology and Plant Quar- 
antine in room 2050, Extensible Building, Independence Avenue and Fourteenth 
Street SW., Washington, D. C, at 2 p. m., September 14, 1936. 
The peach mosaic disease was first observed in Texas in 1931 by Federal 
inspectors and was identified by the Bureau of Plant Industry as a previously 
unknown virus disease. The presence of this disease has since been determined 
in California, Colorado, New Mexico, and Utah. 
Special investigations begun in 1931 by the United States Department of 
Agriculture to determine the cause of the disease and the methods of control 
have resulted in finding that the disease is communicable and is spreading in 
the manner of a contagious disease, but the exact cause or nature of the con- 
tagion is unknown. From this information it appears advisable to prohibit or 
restrict the shipment of peach and nectarine trees and parts thereof from the 
infected States in an effort to prevent its spread to other peach districts. 
With the onset of the disease, a peach mosaic infected tree develops shortened 
internodes, the blade and leaf axils start intergrowth in profusion, and the leaf 
blades develop striking mosaic patterns and in many instances are small, nar- 
row, irregular in outline, and crinkly. After the disease appears there is a 
notable decrease in the average size of the fruit, which is apt to be irregular 
in shape and the texture of the pulp is inclined to be pithy. 
The hearing is called by the Secretary of Agriculture in accordance with the 
Plant Quarantine Act in order that any person interested in the proposed 
quarantine may appear and be heard, either in person or by attorney. 
NOTICE OF PUBLIC HEARING TO CONSIDER THE ADVISABILITY OF QUARANTINING 
THE STATES OF CALIFORNIA, COLORADO, NEW MEXICO, TEXAS, AND UTAH ON 
ACCOUNT OF THE PEACH MOSAIC DISEASE 
August 19, 1936. 
The Secretary of Agriculture has information that peach mosaic, a dangerous 
plant disease not heretofore widely prevalent or distributed within and through- 
out the United States, exists in portions of the States of California, Colorado, 
New Mexico, Texas, and Utah. 
It appears necessary, therefore, to consider the advisability of quarantining 
the States of California, Colorado, New Mexico, Texas, and Utah, and of 
restricting or prohibiting the movement of peach and nectarine trees and parts 
thereof from these States or from any districts therein designated as infected. 
Notice is, therefore, hereby given that in accordance with the Plant Quarantine 
Act of August 20, 1912 (37 Stat. 315), as amended by the act of Congress 
approved March 4, 1917 (39 Stat. 1134, 1165), a public hearing will be held 
before the Bureau of Entomology and Plant Quarantine in room 2050, Bureau 
of Agricultural Economics conference room, Extensible Building, Independence 
Avenue and Fourteenth Street SW., Washington, D. C, at 2 p. m., September 14, 
1936, in order that any persons interested in the proposed quarantine may 
appear and be heard, either in person or by attorney.
