cut flowers thereof may be shipped interstate without inspection or certification * 
under these regulations on condition that each box or package thereof is plainly- 
labeled to show that the contents were greenhouse grown. 
(6) Herbaceous plants unrestricted. — No restrictions l are placed by these 
regulations on the interstate movement of strawberry plants, or of other herba- 
ceous annual or perennial plants or parts thereof. 
Regulation 6. Conditions Governing the Issuance of Certificates 
(a) Application; assembly of articles for inspection. — Persons intending to move 
or allow to be moved restricted articles interstate shall make application therefor 
as far as possible in advance of the probable date of shipment. Applications 
must show the nature and quantity of the plants or plant products or stone or 
quarry products it is proposed to move, together with their exact location, and, 
if practicable, the contemplated date of shipment. Applicants for inspection 
will be required to assemble or indicate the articles to be snipped so that they can 
be readily examined by the inspector. If not so placed inspection will be refused. 
Articles to be inspected must be free from ice and snow and in condition to make 
inspection easily practicable. 
(b) Nursery-grown stock. — With respect to nursery-grown stock, Federal inspec- 
tion and the issuance of Federal certificates authorizing the interstate movement 
of nursery products will be conditioned on the presentation of a valid State cer- 
tificate stating that the nursery in question has been inspected by a State nursery 
inspector and certifying that it is apparently free from infestation with gypsy 
and brown-tail moths. Such State certification shall be renewed each year, 
shall be based on an inspection made as promptly as practicable after the egg- 
laying period of the gypsy moth, and shall be valid for the purpose of Federal 
certification, until the following egg-hatching period, except that, pending rein- 
spection, shipments may be inspected and certified for interstate movement on 
the basis of the State certification of the preceding year. Whenever any nursery 
or independent unit thereof in the regulated area, or any shipment therefrom, is 
reported by a State inspector to be appreciably infested with either the gypsy 
moth or the brown-tail moth, or whenever such infestation is determined by a 
Federal inspector on his examination of material offered for shipment, further 
certification for interstate movement from such nursery, or independent unit 
thereof, will be refused until such nursery has been freed from infestation and 
has been again inspected and certified by the State to be apparently clean. 
During the larval period of the gypsy moth all nursery stock shall be assembled 
for the examination of the Federal inspector, and if passed by him as free from 
any infestation, either by egg masses or wind-blown larvae, it may then be lined 
up and thoroughly sprayed under the direction of and in manner and method 
satisfactory to the said inspector, who will certify each shipment as having been 
thus inspected and treated. 
(c) Native trees and shrubs. — With respect to living trees and plants not grown 
in nurseries, inspection and certification for interstate movement will be condi- 
tioned upon the presentation of a statement by the applicant indicating the 
exact source of such trees and plants, and in addition to such statement, if dug 
on land other than the property of the applicant, a permit from the owner of the 
said land authorizing such digging, provided such permit is required under the 
law of the State wherein the land is situated. If the inspection of the trees or 
plants intended for shipment discloses infestation with either the gypsy moth or 
brown-tail moth, certification will be refused as to the intended shipment and 
as to other similar shipments of trees or plants originating on the same property 
or in the same locality. 
(d) Forest products and stone and quarry products. — Certificates of inspection 
authorizing the interstate movement of forest products and stone and quarry 
products may be issued under either of the following conditions: (1) When the 
articles to be shipped have actually been inspected and found free from infesta- 
tion; or (2) when the articles have been disinfected under the supervision of an 
inspector in such a manner as to eliminate all risk of infestation. With respect 
to quarries, and with respect to yards or other places where forest products are 
assembled for shipment, as a condition of inspection and certification the premises 
or surroundings of such places shall be cleaned up and kept free from gypsy moth 
infestation. 
i Shipments of such plants and flowers from the area regulated under the Japanese beetle quarantine are 
subject to the certification requirements of that quarantine.
