“ in Kentucky.
(9) All certificates and permits automatically expire june 30 fol- ‘
lowing 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
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 summary 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 mirsery
inspection certificate with the proper administrative authority before
i shipments are made. Only three states require filing fees, except under
special conditions, that are noted in a table which follows.
. Special shipping tags are required by the following states and will
, be furnished by them at a nominal cost to the shippers: Arkansas ($2 per
100 tags); Florida ($3. 24 per 100 tags); and New Mexico ($1. 25 per 100
. tags).
A special tag should be secured and attached to each bundle of nur-
sery stock shipped to any of the three states listed.

Federal Quarantine Number 38, because of Black Stem Rust, was
amended by the Secretary of Agriculture to become effective February
11, 1950. Among the important changes in regulations are: (1) the
elimination of the requirement to place a special permit tag on each
package of barberry, mahonla, or mahoberberis shipped interstate; (2)
shipments of seeds and fruits of approved species and varieties when pro-
duced within the eradication states, can be moved under certificate A
only lf going to another eradication state. Seed or fruit produced out-
side the eradication states cannot be shipped into any of the eradication ‘
states. ‘
The requirements of Federal Quarantine Number 38 are summarized
as follows: (1) The eradication states are: Colorado, Illinois, Indiana,
Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska,
North Dakota, Ohio, Pennsylvania, South Dakota, Virginia, Washing-
ton, West Virginia, Wisconsin, and Wyoming; (2) Barberry, mahonla,
and mahoberberris, 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

 Inspection of Nursery Stock, 1956-57 13
known to be rust resistant and approved by the Branch will be acceptable
for certification. 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 lmown to be resistant to rust cannot be shipped
V interstate and growers who have such rust susceptible species will be re-
quired to destroy them before permits to ship approved varieties are
granted; {5) The following species and varieties of baxberry, znahonia,
and mahoberberis are designated as mt resistant:

Under provisions of Federal Quarantine Number 37 certain limita-
tions are placed under the Lmportatlon 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. ,
209 River Street, Hoboken, New jersey. In applying for a permit to
import plant material the following imformation is required; ga) The

 Inspection of Nursery Stock, 1956-57 15
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.
All restricted plants imported under the conditions listed above are
limited in size and age to the youngest and smallest which can be suc-
cessfully freed from soil about their roots, transported to the United
States, and established in this country with a reasonable degree of suc-
A cess. Certain classes of plants permitted entry under quarantine 37 are
required to be grown by the importer under post entry inspection regu- ·
. lations. Such plants are not released to the trade until such time as
their freedom from plant diseases and insect pests has been established.
The plants are therefore grown for one or more years in a place where
the state inspector may have access to them for inspection purposes,
for such tlme as appears necessary. When their freedom from pests
~. and diseases has been established, the plants under quarantine are re-
X leased.
A comparatively new disease, oak wilt (Endoconidiophora fagace-
arum) 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 t.he red and black groups seem to become infected
with oak wilt more readily than 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 shown by the ap-
pearance of leaves on the upper branches. They show dull light green
color and curl upward. Later the leaves may tum yellow or reddish
brown before falling. All leaves may fall within a month after first
symptoms occur. In white and burr oaks the disease develops more
slowly, with one or more branches near the top showing disease symp-
. l toms first.
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
possibly spread the disease.

 16 ~ Regulatory Bulletin 139
As the oak wilt fungus develops under the bark of infected trees,
fungus cushions or mats are formed. These mats enlarge and thicken,
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 Nitidullds. These beetles, as
well as the common fruit flies, are attracted by the characteristic odor
of the fungus. After crawling over the fungus mats and becoming con-
taminated with spores of the fungus, the insects move on to other trees
and wherever there is a wound in the tree the contaminated insect is
capable of bringing the spores of oak wilt into contact with the sap wood
of uninfected oaks, there by starting new infections.
There seems to be some association between the long distance
spread of oak wilt and the activities and travel of man since so many
of the new disease finds have been along highways and other heavily
traveled lanes.
Oak wilt is known to occur in Arkansas, Illinois, Indiana, Iowa, ‘
Kansas, Kentucky, Minnesota, Maryland, Michigan, Missouri, Nebras-
ka, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West
Virginia and Wisconsin. Nurseryrnen, foresters, and all others inter- .
ested in preventing the loss of oaks should be on the alert for this trou-
ble. Samples of twigs from oaks showing symptoms of the disease ‘
should be sent to the Southeastern Forest Experiment Station, Federal
Building, Ashville, North Carolina.
Six twigs or branches about 6 to 8 inches long and 1/2 to 1 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 in such a
manner as to couple the laboratory report with the tree from which the
twigs were taken.
Kentucky is fortunate in having a well organized Department of For-
estry under the capable supervision of experienced men. Mr. H. B. New-
land, State Forester, and Mr. Harry Nadler, in charge of Forestry Manage- )
ment, are well aware of the potential dangers of oak wilt disease and have
set up a well coordinated program of survey and control. They do not con- ~
sider oak wilt a disaster problem but one which is potentially serious and I
will require long range planning.

 Inspection of Nursery Stock, 1956-57 17
A The area of heaviest oak wilt disease infection in Kentucky is located
in Breathitt and Perry Counties. Since the first oak wilt diseased tree was
found in Greenup County in 1950, the entire state has been surveyed. The
disease seems to be fairly widespread in the eastern part: of the state but
comparatively rare in Western Kentnclqr. Much work is yet to be done be-
fore odicials can predict the future of oak wilt disease.
Elm phloem necrosis and Dutch elnz disease have been found to oc- _
cur in the state of Kentucky. Elm phloem necrosis has been by far the
most destructive disease of elms yet known to Kentucky forests and
landscape plantings. Dutch elm disease has been found in only a small
number of elms in northern Kentucky near Cincinnati, Ohio. Although
no cure is known for these maladies, measures can be taken to protect
healthy trees from infection.
Dutch elm disease or phloem necrosis should be suspected when-
ever elm foliage suddenly wills and the dry, dead leaves adhere to the
branches; or when the leaves of an entire branch, or the top, turn yel-
low and fall prematurely. To further identify the diseases, cut through
the bark at ground level, or below, and pry the bark from the wood so `
the inner bark will show. If the inner bark surface is yellow or like but-
terscotch in color, phloem necrosis is indicated. If a portion of the in-
ner bark is confined in a bottle or the closed hands for a few minutes a
faint odor of wintergreen can be detected from phloem-necrosis-diseased
To test for Dutch elm disease remove several small branches having
wilted, yellow, or dying leaves. If the cross sections where cuts are
made show several brown spots or dlscolorations in one or more annual
rings of wood, the trouble is probably Dutch elm
