ANNOUNCEMENTS RELATING TO WHITE-PINE BLISTER-RUST 
QUARANTINE (No. 63) 
REVISION OF WHITE-PINE BLISTER-RUST QUARANTINE REGULATIONS 
INTRODUCTORY NOTE 
The following revision of the white-pine blister-rust quarantine regulations 
adds five States to the list of States designated as infected with the rust. These 
are Iowa, Maryland, Ohio, Virginia, and West Virginia. Since the District of 
Columbia is surrounded by infected States, it is also classed as infected although 
the blister rust has not yet been found within the limits of the District. 
The new regulations will widely increase the market for 5-leafed pines raised 
under conditions in which they are protected from rust infection. The embargo 
which prohibited the shipment of such pines from infected to noninfected States 
is removed, and the Federal pine-shipping permits which heretofore authorized 
shipments only between infected States may now be used for shipments to non- 
infected States also. The change is based on the satisfactory results of the pro- 
tective work carried out around nurseries during the past several years. 
At the same time the interstate movement into other infected States, of 
5-leafed pines grown in the lightly infected States, is somewhat more restricted 
than heretofore, experience indicating that such pines should be raised in a 
Ribes-free environment in order to be considered safe from blister rust. 
The embargo which has hitherto prohibited the movement of 5-leafed pines 
from points east of the Missouri Valley to the Western States is removed. 
The interstate shipment of currant and gooseberry plants is also simplified 
by the elimination of the provision that such plants if transported from the 
infected States were required to be both dormant and dipped in lime-sulphur 
solution. Hereafter such plants will not be required to be disinfected in lime- 
sulphur unless shipped with leaves or active buds. 
During the consideration of these changes, the Bureau of Plant Quarantine 
has been in correspondence with the plant-quarantine officers of the various
