SECTION 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: 
(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 been found may be classified as Class I. Upon com- 
pliance with the requirements of subsection (6) 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. — (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. Such 
classification also may be given to nurseries, etc., in localities known to be gen- 
erally infested 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 properties. In the case of nursery properties under single ownership 
and management, but represented by parcels of land widely separated, such 
parcels may be independently classified either as Class I or Class III upon com- 
pliance 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 bound- 
aries of a permanent nature which shall be approximately 500 feet beyond the 
point where the infestation occurs. 
(6) Upon compliance with subsections (3) and (6) 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: (i) That the roots shall be 
treated by means approved by the Bureau of Plant Quarantine in manner and by 
method satisfactory to the inspector; or (it) 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 w r ashmg, or (Hi) 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 all the 
following conditions with respect to the greenhouses themselves and to all potting 
beds, heeling-in areas, hotbeds, coldframes, and similar plots: 
(a) 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. 
3 The interstate movement of narcissus bulbs is subject to the restrictions contained in the Rules and 
Regulations Supplemental to Notice of Quarantine No. 62 (Narcissus Bulb Quarantine).
