MODIFICATION OF MISSISSIPPI STATE PLANT QUARANTINES 
Post Office Department, 
Third Assistant Postmaster General, 
Washington, September 24, 19^1. 
The State Plant Board of Mississippi has established a quarantine under the 
provisions of the law embodied in section 596, P. L. and R., designed to prevent 
the dissemination of black rot, stem rot, nematodes, sweetpotato weevil, and 
other injurious pests of the sweetpotato which restricts the shipment of the 
hosts of these diseases and pests from one point to another within the State of 
Mississippi. 
Under the quarantine no shipments of sweetpotatoes, sweetpotato plants or 
vines may be accepted for mailing unless there is attached to each container 
a certificate tag and each bundle of one hundred plants is tied with a valid 
certificate tape issued by the Mississippi State Plant Board showing compliance 
with the State plant-quarantine laws or regulations pertaining to injurious pests. 
You will please, therefore, take the necessary steps to prevent the acceptance 
of such material except when having the required certificate tag or certificate 
tape attached. 
You are also reminded of the Mississippi State quarantine and regulations 
relating to the shipment of sweetpotatoes, sweetpotato plants, vines, cuttings, 
draws, and slips and morning-glory plants or parts thereof from other States 
into Mississippi as set forth in the notices of this Bureau dated April 7, 1937, 
May 7, 1940, and March 28, 1941, which have been published in the Supplements 
to the Postal Guide.
