[nd Shall carry their Kentucky permits when soliciting orders or delivering
nursery stock in Kentucky.
(9) All certificates and permits automatically expire June 30
following date of issuance.
· Nursery stock includes all trees, shrubs, vines; roses, strawberry,
raspberry and blackberry plants; herbaceous perennial plants and roots;
grass "plugs", "sprigs" and sod; ornamental bulbs, corms, tubers and
:69 rhizomes; and any part of the above groups of plants capable of dissemi-
nating injurious insects and plant diseases. For regulatory purposes
the term “Nursery Stock" includes all plants which grow out of doors
and live more than one year, whether nursery grown or native.
A su mary of the major requirements for shipping nursery stock
into other states is given on the following page. It will be noted
that most states require the out-of-state shipper to file a copy of his
nursery inspection certificate with the proper administrative authority
in before shipments are made. Only three states require filing fees,
ky except under special conditions, that are noted in a table which
TIS Special shipping tags are required by the following states and
¤ will be furnished by them at a nominal cost to the shippers: Arkansas
r' ($2 per 100 tags); Florida ($3.24 per 100 tags); and New Mexico ($l.25
per 100 tags).
A special tag should be secured and attached to each bundle of
nursery stock shipped to any of the three states listed.

Federal Quarantine Number 38, because of Black Stem Rust, was
att- am€¤d€d by the Secretary of Agriculture to become effective February 11,
I 1950. Among the important changes in regulations are: (1) the elimi—
nation of the requirement to place a special permit tag on each package
su-y’ Of bafbefty, mahonia or mahoberberis shipped interstate; (2) shipments
of seeds and fruits of approved species and varieties when produced
10gY within the eradication states can be moved under certificate only if
going to another eradication state. Seed or fruit produced outside the
E eradication states cannot be shipped into any of the eradication states.

 12 Regulatory Bulletin No. 174
The requirements of Federal Quarantine Number 38 are sum arized as
‘ follows: (l) The eradication states are: Colorado, Illinois, Indiana,
. Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska, North
{ Dakota, Ohio, Pennsylvania, South Dakota, virginia, Washington, West
Virginia, Wisconsin and Wyoming; (2) Barberry, mahonia and mahoberberis,
in any variety, can be shipped interstate (to any state) only under
certificate issued by the Plant Pest Control Branch; (3) Application
_ for Federal certificate must be filed in duplicate not later than May 15
each year with the Quarantine Division of Plant Disease Control, ·
Washington 25, D. C.; (4) Only species and varieties known to be rust
resistant and approved by the Branch will be acceptable for certifi-
cation. The list of approved species and varieties is revised from
time to time as new varieties prove to be resistant to stem rust.
Species and varieties not known to be resistant to rust cannot be
shipped interstate and growers who have such rust susceptible species
will be required to destroy them before permits to ship approved
varieties are granted; (5) The following species and varieties of bar-
berry, mahonia and mahoberberis are designated as rust resistant:

Under provisions of Federal Quarantine Number 37 certain limita-
tions are placed on 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 Plant Quarantine Branch, U.S.D.A.,
BO9 River Street, Hoboken, New Jersey. In applying for a permit to
import plant material the following 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 seeds or plants are to be shipped; (c) the number and genus of
the plants or seeds for which the permit is desired.

 lh Regulatory Bulletin No. 174
All restricted plants imported under the conditions listed above new
· are limited in size and age to the youngest and smallest which can be lan
, successfully freed from soil about their roots, transported to the ‘
{ United States and established in this country with a reasonable degree
5 of success. Certain classes of plants permitted entry under quarantine Kan
' 37 are required to be grown by the importer under post entry inspection NOT
regulations. Such plants are not released to the trade until such time and
_ as their freedom from plant diseases and insect pests has been estab- pre
lished. The plants are therefore grown for one or more years in a , Sam,
place where the state inspector may have access to them for inspection Sent
purposes for such time as appears necessary. When their freedom from Ashe
pests and diseases has been established, the plants under quarantine
are released.

Oak wilt disease (Endoconidiophora fagacearum) is now well estab- shou
lished in the woodlands of Kentucky. The disease is caused by a fungus in s
organism that can be identified by plant pathologists in one to two whic
year old vascular tissue from infected trees.
Varieties of the red and black groups seem to become infected with supe
oak wilt more readily than white and burr oaks, although all species serv
and varieties of oaks are susceptible to the disease. inte
54 c
The first symptoms in the red and black oaks are shown by the had
appearance of leaves on the upper branches. They show dull light green deep
color and curl upward. Later the leaves may turn yellow or reddish alon
brown before falling. All leaves may fall within a month after first wilt
symptoms occur. In white and burr oaks the disease develops more This
slowly with one or more branches near the top showing disease symptoms spre
Spread of the disease from diseased to healthy trees within native
stands of oaks can occur through natural root grafts or unions. During
recent years it has been proven that certain insects are capable of
` carrying the disease from tree to tree and that even squirrels might over
possibly spread the disease. recer
As the oak wilt fungus develops under the bark of infected trees, knowr
fungus cushions or mats are formed. These mats enlarge and thicken, trees
` thereby creating sufficient pressure to crack the bark and separate it
from the wood. As soon as the cracks are formed they are invaded by
several species of sap beetles known as Nitidulids. These beetles, as elm i
well as the common fruit flies, are attracted by the characteristic odvf bYa¤C
of the fungus. After crawling over the fungus mats and becoming contami· and {
nated with spores of the fungus, the insects move on to other trees and the b
wherever there is auwund in the tree the contaminated insect is capable the i
` of bringing the spores of oak wilt into contact with the sap wood of butte
uninfected oaks, thereby starting new infections. the i
E There seems to be some association between the long distance spread necro
of oak wilt and the activities and travel of man since so many of the

 Plant Pest Control Law Administration, l96l·62 l5
new disease finds have been along highways and other heavily traveled
Oak wilt is known to occur in Arkansas, Illinois, Indiana, Iowa,
€ Kansas, Kentucky, Minnesota, Maryland, Michigan, Missouri, Nebraska,
H North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia
e and Wisconsin. Nurserymen, foresters and all others interested in
preventing the loss of oaks should be on the alert for this trouble.
· Samples of twigs from oaks showing symptoms of the disease should be
sent to the Southeastern Forest Experiment=Station, Federal Building,
Asheville, North Carolina.
Six twigs or branches about six to eight inches long and one—half
to one inch in diameter are best for laboratory examination. The twigs
should be alive or just recently dead but not completely dry. Do not
send leaves, dead branches or decayed wood. The twigs should be tied
in a bundle, wrapped in paper so as to prevent excessive drying but
- should not be wrapped in wet moss or cotton. Labels should be attached
is in such a manner as to couple the laboratory report with the tree from
which the twigs were taken.
The oak wilt survey and control program in Kentucky is under the
;h supervision of the Kentucky Division of Forestry, Department of Con-
servation. In its annual report on "Oak Wilt in Kentucky" some
interesting and encouraging figures are given. Since l95l a total of
54 counties have had oak wilt but in 1959 only 35 of these counties
had centers of oak wilt infection. Oak wilt centers of infection
