regulated area, or from a regulated area through a nonregulated area to 
another regulated area, except that a certificate is required between June 15 
and October 15 for interstate movement of cut flowers, aquatic plants, and of 
portions of plants without roots and free from soil (such as branches, twigs,

Brewer and Waterville, Maine ; Buffalo, Hornell, Mount Morris, and Water-

B. Conditions governing the issuance of certificates and permits. — For the 
purpose of certification of nursery and ornamental stock, nurseries, greenhouses, 
and other premises concerned in the movement of such stock will be classified 
as follows : 
(5) Class 7.— Nurseries, greenhouses and other premises concerned in the 
movement of nursery and ornamental stock on or within approximately 500 
feet of which no infestation has been found may be classified as class I. 
Upon compliance with the requirements of paragraph 10 of this regulation, 
nursery and ornamental stock may be certified by the inspector for shipment 
from such premises without further inspection, and without meeting the 
safeguards prescribed as a condition of interstate shipment of plants originating 
in nurseries or greenhouses of class III. 
(6) Class III. — (a) Nurseries, greenhouses, and other premises concerned 
in the movement of nursery and ornamental stock on which either grubs in the 
soil or one or more beetles have been found, will be classified as class III, 
provided, (/) there are maintained on the premises subdivided class I areas, 
certified houses, frames, or plots, or other certified areas, or (U) there is a 
legitimate need for interstate or intradealer certification of such stock. Such 
classification will not be granted to nurseries, greenhouses, and other premises 
that do not maintain certified or subdivided areas and require only infrequent 
certification. Such classification also may be given to nurseries, etc., where 
one or more beetles or grubs are found in the immediate proximity (within 
approximately 500 feet) of such nurseries, etc., on adjacent property or prop- 
erties. In the case of nursery properties under single ownership and manage- 
ment but represented by parcels of land widely separated, such parcels may 
be independently classified either as class I or class III upon compliance with 
such conditions and safeguards as shall be required by the inspector. Similarly, 
unit nursery properties, which would otherwise fall in class III, may be open 
to subdivision, for the purpose of rating such subdivisions in classes I or III. 
when in the judgment of the inspector such action is warranted by recent and 
scanty infestation limited to a portion of the nursery concerned : Provided, 
That the subdivision containing the infestation shall be clearly marked by 
boundaries of a permanent nature which shall be approximately 500 feet beyond 
the point where the infestation occurs. 
(&) Upon compliance with paragraphs (7) and (10) of this regulation, 
nursery and ornamental stock may be certified by the inspector for shipment 
from such premises under any one of the following conditions: (i) That the 
roots shall be treated by means approved by the Bureau of Entomology and 
Plant Quarantine in manner and by method satisfactory to the inspector ; or 
(ii) in the case of plants in which the root system is such that a thorough 
inspection may be made, that the soil shall be entirely removed from the stock 
by shaking or washing: or (Hi) that it shall be shown by evidence satisfactory 
to the inspector that the plants concerned were produced in a certified 
greenhouse.
