ANNOUNCEMENT RELATING TO NURSERY STOCK, PLANT, AND SEED 
QUARANTINE (NO. 37) 
TREATMENT OF TULIPS, HYACINTHS, AND CERTAIN OTHER KNOWN HOSTS OF 
THE BULB NEMATODE NOT TO BE REQUIRED 
February 15, 1937. 
A conference was held in Washington, D. C, on December 15, 1936, to con- 
sider the desirability of re(iniring the treatment under the provisions of the 
Nursery Stock, Plant, and Seed Quarantine No. 37, of all known bulb nema- 
tode hosts intended for propagation and not at that time being treated as a con- 
dition of entry. The evidence presented at the conference indicated that the 
bulb nematode risk which accompanies the importation of most ornamental bulbs 
which have been inspected in the country of origin, supplemented by inspection 
at the port of entry in the United States, does not justify the requirement that 
all known hosts to be treated as a condition of entry. No change in the require- 
ments as to importation of narcissus bulbs is announced at this time.

[Press notice] 
February 19, 1937. 
A revision of the white-pine blister rust quarantine regulations, effective 
March 1, was announced today by tlie Secretary of Agriculture. 
The revision adds Maryland, Ohio, Pennsylvania, and Wisconsin to tlie list' 
of States which have established blister rust-c ontrol areas, in which both the 
planting and possession of currant and gooseberry j)l;ints are prohibited under 
State aulliorily. Stairs to which this provision previously ap])lied are Con- 
necticut, Idaho, Maino, Massaciiusetts. Minnesota. .Michigan, New Hampshire, 
New York, Rhode Island, and Vermont. The purpose of this provision is to 
l)revent the introducMon of the alternate host plants of the disease (currant 
and gooseberry plants) into the portions of the States where five-leafed pines 
are of economic importance and from which such hosts have been or are being 
removed. 
Conditions under which Federal permits may be issued for the interstate 
shipment of five-leaf (m1 pines from States vvh(u-e the blister rust is known to 
be present, are modified so that such pines — vviiich have not been raised from 
the seedling stage under the rigid disease-free conditions previously pre- 
scribed — may now be moved interslate wlien. in the judgment of the Bureau 
of Entomology and Plant Quarantine, there is little or no risk of such pines 
spreading the rust. 
Regulations pertaining to five-leafed pines also are revised to prohibit their 
interstate movement when visibly infected with the white-pine blister rust, un- 
less such trees are shipped in a preservative or are authorized and labeled 
under the provisions of regulation 7. which provides that such infected trees 
may be shipped interstate by the United States Dc^partment of Agriculture for 
experimental, educational, or scientific purposes under safeguards prescribed by 
the Bureau of Entomology and Plant Quarantine.
