PLANT IMPORTATION
Under provisions of Federal Quarantine Number 37 certain limita-
tions are placed upon the importation of plants and seeds from foreign
countries. Anyone wishing to import nursery stock, plants, or seeds
must first obtain a permit from the Bureau of Entomology and Plant
Quarantine, 209 River Street, Hoboken, New jersey. In applying for
a permit to import plant material the follwoing information is required:
(a) The name and location of the producer from whom the plants or
seeds are to be secured; (b) the name and address of the person or firm
to which the plants or seeds are to be shipped; (c) the number and genus
of the plants or seeds for which the permit is desired.
All restricted plants imported under the conditions listed above are
limited in size and age to the youngest and smallest which can be S1C·
cessfully freed from soil about their roots, transported to the United ·
States, and established in this country with a reasonable degree of suc-
cess. Certain classes of plants permitted entry under quarantine 37
are required to be grown by the importer under post entry inspection
_ regulations. Such plants are not released to the trade until such time
as their freedom from plant diseases and insect pests has been estab-
lished. The plants are therefore grown for one or more years in a
place where the state inspector may have access to them forinspection
purposes, for such time as appears necessary. When their freedcrn
from pests and diseases has been established, the plants under quaran -
tine are released.
OAK WILT
A comparatively new disease, oak wilt (Chalara quercina Henry),
is threatening all oaks in the midwest. The disease is caused by a
fungus organism that can be identified by plant pathologists in one -to
two-year old vascular tissue from infected trees.
Varieties of the red and black groups seem to become infected i
with oak wilt more readily then white and burr oaks, although all _
species and varieties of oaks are susceptible to the disease.
The first symptoms in the red and black oaks are the appearance
of leaves on the upper branches. They show dull light green color and
curl upward, Later the leaves may turn yellow or reddish brown before
falling. All leaves may fall within a month after first symptoms occur .
ln white and burr oaks the disease develops more slowly, with one or
more branches near the top showing disease symptoms first.
Spread of the disease from diseased to healthy trees within native
