ANNOUNCEMENTS RELATING TO WHITE PINE BLISTER RUST 
QUARANTINE (FOREIGN) (NO. 7) 
LIFT SPECIAL QUARANTINES ON FOREIGN PINE TREES 
[Press notice] 
July 23, 1936. 
Foreign Plant Quarantine No. 7, as amended, which prohibits the entry into 
the United States of white pines, currants, and gooseberries from Europe, Asia, 
Canada, and Newfoundland, and Foreign Plant Quarantine No. 20, which pro- 
hibits the entry of certain pines from Europe, have been lifted by the United 
States Department of Agriculture. The order, signed July 20 by Acting Secre- 
tary of Agriculture W. R. Gregg, becomes effective September 1, 1936. Control 
will be continued under Foreign Plant Quarantine 37, which provides that plants 
can be imported only under permit and such safeguards as are necessary to pro- 
tect against the entry of various pests. 
Foreign Plant Quarantine No. 7 was promulgated in 1913 to prevent the intro- 
duction into this country of the white pine blister rust, which passes part of 
its life cycle on .currants and gooseberries. The host plants of this serious 
plant disease can now come in under certain conditions without any risk of 
spreading it to new localities. Foreign plant quarantine no. 20 was promul- 
gated in 1915 to prevent the entry of the European pine shoot moth. This 
insect pest is now established in some parts of the eastern United States. 
WHITE PINES, CURRANTS, AND GOOSEBERRIES FROM EUROPE, ASIA, CANADA, AND 
NEWFOUNDLAND BROUGHT UNDER QUARANTINE 37 BY REVOCATION OF QUAR- 
ANTINE 7 
INTRODUCTORY NOTE 
As promulgated on May 21, 1913, February 29, 1916, and April 21, 1917, 
respectively, Notice of i Quarantine No. 7 and its amendments nos. 1 and 2 pro- 
hibited entirely (except for experimental purposes by the Department of Agri- 
culture) the entry into the United States from Europe, Asia, Canada, and 
Newfoundland of five-leafed pines, currants, and gooseberries. The object of 
this quarantine was to prevent the introduction into this country of the white 
pine blister rust, an injurious plant disease. Our present knowledge of the 
distribution of this disease in this country, and of factors necessary for its 
establishment, indicates that, under certain conditions, host plants may be per- 
mitted entry without the risk of spread of the disease to new localities. For 
that reason a completely prohibitory quarantine is deemed no longer necessary. 
The revocation of quarantine no. 7 automatically places the entry of white 
pines, currants, and gooseberries under the provisions of Notice of Quarantine 
No. 37, the Nursery Stock, Plant, and Seed Quarantine,' and under that quaran- 
tine their entry will be regulated in harmony with the restrictions of the 
Domestic White Pine Blister Rust Quarantine No. 63.
