SUMMARY OF REQUIREMENTS OF KENTUCKY
NURSERY INSPECTION LAW
(1) It shall be unlawful to sell or offer for sale uninspected or
unceitified nursery stock. A certificate of inspection indicates free-
dom from certain injurious insects and plant diseases but does not
vouch for trueness to variety nor for grade and condition of any .
nursery stock.
(2) Growers of nursery stock, for sale or shipment, shall apply
in writing before ]une lst of each year to the State Entomologist,
Kentucky Agricultural Experiment Station, Lexington, for inspection
services.
(3) Every dealer in nursery stock shall secure a nursery dealer’s
permit. Before this is issued, however, he must fumish an affidavit
that he will buy and sell only stock that is certified and will maintain

 Iusmzcrrou or Nuuszmr Srocic, 1952. — 53 7
with the State Entomologist a correct and complete list of all sources
from which he gets his stock. Landscape architects and tree movers
who handle nursery stock are classified as dealers.
(4) Every person who solicits orders for nursery stock shall ob- _
tain and carry an agent’s permit which is secured only upon request `
. of the nurseryman or dealer to be represented.
(5) All packages or bundles of nursery stock shipped by common
carrier must have attached a copy of the inspection certificate or
permit.
(6) Certificates and permits may be revoked for cause.
(7) Fees shall be paid as follows: Inspection certificate $5;
dealer’s permit, $5. Agents’ permits and nonresident nurserymen’s
certificates are furnished without cost. Fees shall accompany appli-
cation. Application blanks may be obtained from the State Entomolo-
gist.
(8) Nonresident nurserymen shall file copies of their state cer-
tificates and secure nonresident permits. Every package of nursery
stock coming into Kentucky shall have a valid inspection certificate
attached to the package. Nonresident nurserymen, dealers, and
agents shall carry their Kentucky permits when soliciting orders or
delivering nursery stock in Kentucky.
(9) All certificates and permits automatically expire ]une 30
following date of issuance.
"NURSERY STOCK" DEFINED
Nursery stock includes all trees, shrubs, vines; roses, strawberry, I
raspberry, and blackberry plants; herbaceous perennial plants and
roots; ornamental bulbs, corms, tubers, and rhizomes; and any part .
of the above groups of plants capable of disseminating injurious
insects and plant diseases. For regulatory purposes the term “Nursery
Stocl<” includes all plants which grow out of doors and live more
than one year, whether nursery grown or native.
REQUIREMENTS FOR SHIPMENT OF NURSERY STOCK
INTO OTHER STATES
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 nur-
sery inspection certificate with the proper administrative authority

 8 Regulatory Bulletin 107
before shipments are made. Only three states require Hhng fees, ex-
cept 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); Georgia ($1.00 per 100
tags); and New MEXICO ($1.25 per 100 tags).
A special tag should be secured and attached to each bundle of

‘ INTERSTATE SHIPMENT OF BARBERRY
·~ AND MAHONIA RESTRICTED
` Federal Quarantine Number 38, on account of Black Stem Rust was
‘ ammended by the Secretary of Agriculture to become effective February ·
I 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, mahonia, or mahoberberis shipped interstate;
(Z) shipments of seeds and fruits of approved species and varieties are
required to have special permit tags attached when going into any of
the eradication states.
The requirements of Federal Quarantine Number 38 are surn-
marized as follows: (1) 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; (Z) Barberry,
mahonia, and mahoberberis, in any variety, can be shipped interstate
V (to any state) only under certificate issued by the Bureau of Entomolo-
gy and Plant Quarantine; (3) Application for Federal certificate must
x be filed in duplicate, not later than May 15 each year, with the Bureau
of Entomology and Plant Quarantine Division of Plant Disease Control
‘ Washington 25, D. C.; (4) Only species and varieties known to be rust
resistant and approved by the Bureau will be acceptable for certifica-
tion. 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 varie-
ties are granted; (5) The following species and varieties of barberry,
j mahonia, and mahoberberis are designated as rust resistant:

 Inspection of Nursery Stock, 1952-53 13
_ PLANT INIP JRTATION
Under provisions of Federal Quarantine Number 37 certain limita-
tions are placed upon the importation of plants and seeds fr om foreign
— countries. Anyone wishing to irnport nursery, stock, plants, or seeds V
must first obtain a permit from the Bureau of Entomology and Plant
_ Quarantine, 209 River Street, Hoboken, New Jersey. In applying for
I a permit to import plant material ·the following information is required:
i (a) The name and location of the producer from whom the plants or
Seeds &1'€ to be secured; (b) the name and adress 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 irnported under the conditions listed above are
lirnited 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 Witha 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 $1’15P€€l·l°“
regulations. Such plants are not released to the trade· until such tirrie
as their freedom from plant diseases and insect pests has been estab-
. lished. The plants are therefore grown for one or more yea r s in a
place where the state inspector may have access to them for inspection
purposes, for such time as appears necessary. When their freedom
from pests and diseases has been established, the plants under quaran-
tine are released,
OAK WILT
A comparatively new disease, oak wilt (Whalara 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
with oak wilt more readily than white and burr oats, 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
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. In 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
stands of oaks can occur through natural root grafts or unions. Itis
. not known to plant pathologists how the disease is spread from one i
