(b) Conditions (joverning 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: 
(1) Class I. 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 beeen found may be classified as class I. Upon 
compliance with the requirements of paragraph (b) (7) of this section, nursery 
and ornamental stock may be certified by the inspector for shipment from such 
premises without further inspection, and without meeting the safeguards pre- 
scribed as a condition of interstate shipment of plants originating in nurseries 
or greenhouses of class III. 
(2) Class III. (i) 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 (a) there are maintained on the premises subdivided class I areas, 
certified houses, frames, or plots or other certified areas, or (b) 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 approx- 
imately 500 feet) of such nurseries, etc., on adjacent property or properties. 
In the case of nursery properties under single ownership and management but 
represented by parcels of land widely separated, such parcels may be inde- 
pendently 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 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 in- 
festation occurs. 
(ii) Upon compliance with paragraphs (b) (3), (6), and (7) of this section, 
nursery and ornamental stock may be certified by the inspector for shipment 
from such premises under any one of the following conditions: (a) 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 
(o) in the case of plants in which the root system is such that a thorough inspec- 
tion may be made, that the soil shall he entirely removed from the stock by 
shaking or washing; or (c) that it shall be shown by evidence satisfactory to 
the inspector that the plants concerned were produced in a certified greenhouse. 
(3) Greenhouses of class III may be certified upon compliance with alt 
the following conditions with respect to the greenhouses themselves and to 
all potting beds, heeling-in areas, hotbeds, coldframes, and similar plots: 
(i) Ventilators, doors, and all other openings in greenhouses or coldframes 
on premises in class III shall be kept screened in manner satisfactory to the 
inspector during the period of flight of the beetle, namely, south of the 
northern boundaries of Maryland and Delaware between June 1 and October 
1, inclusive, or north thereof between June 15 and October 15, inclusive.
